Document Overview and Purpose

This document looks deeper at the system configuration using Composer software and the
F4T function blocks and their associated connections. Common product usage is described and
illustrated through application examples.

 A Conceptual View of the F4T System
The flexibility of the F4T controller hardware and software (Composer) allows for a large
range of configurations. Composer software is a graphically based tool used to program the
F4T controller in its entirety. To learn more about installing and using Composer software see
Chapter 2 of this document in the section titled "Installing Composer Software".
Acquiring a better understanding of the controllers overall functionality and capabilities while
at the same time planning out how the controller can be used will deliver maximum effec-
tiveness in your application.

Alarms Outputs

It is useful to think of the controller in three parts: inputs, functions and outputs. For the
control itself, information flows from an input to a function to an output when the controller
is properly configured. The F4T system can carry out several functions at the same time; such
as, monitoring and acting upon various inputs (temperature sensing devices, pressure trans-
ducers and digital inputs), PID control, monitoring for several different alarm situations and
then driving output devices such as heaters, audible alarms, and lights. Each process needs
to be thought out carefully and the controllers inputs, functions and outputs set up properly.
As an example, the graphic below illustrates the Function Block Diagram as seen when using
Composer software. The application requirements in this example are simple and defined be-
low:
Need two thermocouple inputs.
Monitor both thermocouple inputs for high process alarms.
Drive an output (alarm) device if either input is higher than expected.
Use one thermocouple input to drive the PID loop (Heat output) with a switched DC
output.
In the graphic below the following is true:
Universal Input 1 is connected to the Process Value (PV) input of the control loop.
When the control loop sees that the
PV is less than the user defined set
point it will drive the output to the
load through its heat (HT) output.
Two unique high process alarms are
configured to monitor Universal Inputs
1 and 2.
The logic function block (FB) is con-
figured as an OR where its output
will come on if either input comes on
driving the real-world digital output
(alarm) it's connected to.
Wa tlow F4T 6 C h ap t er 1 O v e r v i e w
 Note:
In this configuration, the heat output of the control function would be uninterrupted if an
alarm were to occur.
You will find more detailed information regarding the function blocks and how they work fur-
ther on in this document.

Inputs
The inputs provide the information that any given programmed function can act upon. In a
simple form, this information may come from an operator pushing a button, or as part of
a more complex function it may represent a remote set point being received from another
zone.
Each universal input can be configured for thermistors, thermocouples, or RTDs to read the
process variable. They can also read mV/volts, current or resistance, enabling usage of various
devices to read humidity, air pressure, operator inputs and other values. The settings associ-
ated to each analog input must be configured to match the device connected to that input.
Each digital input reads whether a device is on or off (voltage or resistance) and each system
can be equipped with multiple digital I/O modules. Each I/O point must be configured to func-
tion as either an input or output.

Functions
Functions use input signals to calculate a value and or performs an action. A function may be
as simple as reading a digital input as on or off, or reading an analog value (temperature) to
set an alarm state to on or off. As an example, a user could use sensor backup to avoid an un-
wanted shutdown if a failure with the primary sensing device should occur.

Keep in mind that a FB can be a purely internal function (i.e., control loop, alarm, logic,
etc...), while they can also serve as a connection point between real-world devices (i.e., ther-
mocouple, heater etc...) and internal functions like a Universal Input connected to the Control
Loop PV input. To have an effect outside of the controller, an output FB must be configured
to respond to some other function. Functions and all associated dependencies would be con-
figured using Composer software. To learn more about setting up function blocks see Chapter
2 of this document in the section titled "Configuring the Application with the Function Block
Diagram View".

Watl ow F4T 7 C h ap t er 1 O v e r v i e w
 Outputs
Outputs respond to information provided by a function such as, heat power from the output
of the control loop, driving a digital output based on a profile event, turn a light on or off,
unlocking a furnace door or turning on a buzzer.
More than one output can be assigned to respond to any given function, i.e., more than one
output device could be connected to the heat output of the control block. Another example
(not shown), could use the (internal) output of the alarm function and connect it to any avail-
able real-world output to trigger a flashing light and another real-world output that might be
connected to a siren.

A profile is a set of instructions consisting of a sequence of steps. When a profile runs, the
controller automatically executes its steps in sequence. The step type determines what ac-
tion the controller performs. Steps can change temperatures and other process values gradu-
ally over time, maintain the temperatures and process values for specific periods, or repeat a
sequence of steps numerous times. At each step the profile can activate or deactivate outputs
that control other equipment. Also a step can have the controller wait for specific conditions
before proceeding such as, waiting for a switch closure and/or a specific process value to be
detected by a sensor.

Data Logging
Controllers equipped with this feature will have the letter [J, K, L or M] in the fifth character
of its part number (see: F4T Ordering Information). Logging can be enabled at any time and is
intended to capture real-time data for a user selectable list of data points. With firmware re-
vision 3.0 and above, several new features are available.
1. User can determine if logged files will be moved automatically and or manually.
2. Destination of the saved file can be directed to internal memory, USB thumb drive, TFTP
server or a Samba shared drive.
3. Based on user choice, files can now be encrypted (filename.enc) for security purposes and
or saved as comma separated values (filename.csv). Creating both file types allows viewing
of the csv file while maintaining the integrity of the encrypted file.
To learn more about configuring these options see the section in this user's guide entitled Set-
ting Up Data Log Files Using Composer.

Data Logs Menu
Decrypt Log File: allows for de-
cryption of an encrypted data log
file.
View: displays the con-
tents of a data logged file
(enc or csv). Depending on files size this may take several minutes to open.
To decrypt an encrypted file follow the steps below:
1. If data logging has not yet been stopped do so now by pushing: Main Menu -> Data Log-
ging -> Stop buttons.
Note:
When data logging is stopped, allow at a minimum, six minutes for closure of all
files and movement of those files to the selected destination before attempting de-
cryption.
2. Open up Composer software and click on Data Logs and then Decrypt Log Files.
3. Locate the encrypted files and open them one-by-one (click on one *.enc file and click
Open), or by selecting more than one and click the Open button.
Note:
If logged file is sent to USB, the *.csv and the *.enc file are written directly to USB
constantly. If the File Size Limit is set to 10MB or larger, the csv will continue to be
written continuously while the encrypted portion (*.enc) is chunked into 7.5MB files,
buffered internally and then written out as 7.5MB chunks. If the maximum file size
is set to 10MB, there will be two *.enc files for each csv (7.5MB and 2.5MB). If File
Size Limit is set to 15MB, there would be two 7.5MB *.enc files for each *.csv file.

 Note:
As noted above, if a csv file is greater than 10MB there will be more than one en-
crypted file for the associated csv file. When decrypting these files, it is recom-
mended that all encrypted files be selected in the decryption process. Each of the
encrypted files will be concatenated into one csv file.
4. After selecting the desired encrypted files and then clicking Open, the window below
will appear. Notice the filename of the original csv and the one suggested in the dialog
box highlighted yellow below. The one within parentheses (1) is inserted to avoid over-

curity is enabled, a user must enter a password to gain access to protected features through
the controller's user interface or Composer software.
There are three configurable user groups and an admin account:
User: no password required, admin sets feature access
User with Password: requires a password, admin sets feature access, is permitted to
change the password for this user group.
Maintenance User: requires a password, admin sets feature access, is permitted to change
the password for this user group.
Admin: requires a password, has unlimited access to features, sets permissions and pass-
words for all user groups.
The Admin user can set permissions for each user group to allow full, read-only or no access
to the following features:

 Configuring Pluggable Flex Modules
This controller can have up to six Flex Modules (FM) installed in the chassis. The presence of
each FM must be confirmed and accepted using Composer software. FMs can be fully config-
ured as installed hardware or the user can type in a valid FM part number for later installa-
tion. For more detail regarding the module installation process, see the Installation and Trou-
bleshooting User's Guide for the controller in use.
Note:
Typing in a valid part number without the presence of the module is intended for the sole
purpose of building the FBD (connecting function blocks on the canvas). Errors may be
generated and all outputs will be off until the module is inserted.
Topics discussed in this section follow:
Screen Orientation: detailed description of the Pluggable Module configuration screen and as-
sociated characteristics.
Symbols Related to Pluggable Modules: description of the symbols that may be displayed when
using Composer software.
Configuring Flex Modules: configuration process described.
Entering FM Information Before Module Installation: detailed description of the why and how
a user would do this prior to acquiring the module.
Note:
The graphic below represents a controller that first had its flex modules installed with the
controller then being connected to a computer. Because of this scenario each slot appears
with no expected modules. This screen and symbols that are displayed will look different
using a different scenario.
Navigate to Pluggable Modules screen:
1. From any screen click on the Device Menu tab to drop down a submenu.
2. Click the Pluggable Modules button.

Detect Modules
The controller will shut off all outputs and initiate an evaluation of each slot to see if
any modules are present.
Note:
In the graphic above, if a module were inserted in slot 3, clicking detect modules will turn
the power on for the slot and report back with the module part number installed.
Finish
Will cause the controller to restart and take the user to the Function Block Diagram.
Note:
There are some FM slot dependencies. If there is a question as to whether or not an FM is
in an acceptable slot, refer to the Installation and Troubleshooting Guide for the controller
in use.

Symbols Related to Pluggable Modules

As viewed from the Menu bar, the symbol that will be displayed to the left of the
Pluggable Modules button will be of the most significance. The red exclamation will al-
ways take precedence.
Symbol Description

The expected module has been detected.

No module has been detected in a slot the controller expects to be empty.

A module has been detected in a slot the controller expects to be empty.

The controller expects a module, but that module is missing or a different

module has been detected.

Configuring Flex Modules

To accept the detected modules:
Note:
If modules were plugged in after powering up or resetting the controller, click on the De-
tect Modules button to restart the controller and detect all of the modules that are pres-
ent.

1. On the right side of the screen click the Use Detected Part Number button.
2. Repeat step 1 for each slot to be configured.
3. Click the Finish button to restart the controller and exit to the Function Block Editor.
Note:
Exiting the pluggable modules screen after any changes are made will cause the controller
to restart. A restart will stop all controller activities while turning off all outputs.

Watl ow F4T Controlle r 1 9 C h ap t er 2 C o n f ig u rat io n U sin g Co m p o s e r

 Entering Flex Module Information Prior to Installation
Function blocks associated with hardware will not be available until the hardware is expected
to be present. Entering a part number for any slot (even though the module is not currently
installed) allows the programmer access to the associated function blocks. As an example, if
an FMMA-UEKA-AAAA is installed in slot one,
the function blocks that would be available are
shown in the red box. After entering a part
number such as FMLA-YEBA-AAAA in slot 2, ad-
ditional hardware dependent function blocks
will appear as shown in the blue box.
Note:
When configuring modules as described
above (not installed), the controller will not
be able to control any outputs. All outputs
will be off.
To configure the controller to expect a module that is not yet installed:
1. Select the desired slot and enter a valid part number in the Expected Part Number field.
2. On the keyboard, push the Enter key.
3. Click Finish when complete to restart the controller. After the restart process is complete
the Function Block Diagram will appear.
Once the module is acquired, simply plug it into its assigned slot and click the Detect Mod-
ules button. After doing so, the controller will restart and a green flag will be displayed for
that slot number.

Configuring the Application using the Function Block Diagram

 Getting Started with the Function Block Diagram (FBD)
The basic steps for creating the function block diagram for any application are:
1. Add the function blocks from the library to the canvas that are needed to interpret the
signals from the physical inputs and set the physical outputs. Typically, these will include
Loop, Alarm and Profile Engine function blocks.
2. Connect the transmitters on the FBs that source data to the receivers on the FBs that
need the data.
3. Set each function block's parameters as needed for the application to perform as expect-
ed.
Detailed descriptions of each function block including all the function block's parameters can
be accessed in the online help for the function block and in the User's Guide, chapter entitled
Function Block Reference.
The FBs that represent the physical inputs and outputs from the controller and are associated
with the flex modules that are expected in the configuration are always on the canvas. These
FBs can only be removed by changing which modules are expected using the Pluggable Mod-
ules view.
Other FBs can be added to the canvas from the library. Some of these FBs such as Loop, Cas-
cade, Alarm and Profile Engine perform sophisticated functions. See the Application Examples
chapter in this User's Guide for more on these functions. Other function blocks such as Math
and Logic perform fundamental functions that can be combined to add custom behaviors to
the controller for specific applications.
The signals that carry data between function blocks normally appear as black lines in the dia-
gram, but when the block that transmits the signal cannot determine what the correct value
should be, the signal changes to yellow indicating the error. Each FB's response to errors re-
ceived is explained in the description of the function block.
Warning:
Once an output FB receiver is connected to another block, the output on the flex module
turns on according to the received signal. Do not connect outputs until it is safe to do so.
Notable facts about the FBD:
How a FB responds to its inputs and drives its output is dependent on its parameter set-
tings. Set the parameters for each function block as needed for the application.
Signals cannot be moved after they are created; to change where a signal gets data or
where it delivers it, delete the signal and create the desired connection.
There are several ways to do many things. Try right-clicking to see options or short
cuts.
FBs from the library that have no signals connected are returned to the library when
Composer is closed.
The location of dockable windows is not saved; windows return to their default loca-
tions when the system is closed.
The selection of signal values displayed in the diagram is not saved; all signal value dis-
plays are turned off when the system is closed.

 Hints:
Click-and-drag any blank spot on the canvas to change the view.
Use the scroll bars.
Use the Navigator to reposition the view of the canvas and to zoom in or out.
Use the mouse wheel to scroll the view. Hold the shift key to use the mouse wheel to
pan. Hold the Control key to use the mouse wheel to zoom.

Selecting and Placing Function Blocks on the Canvas

To place a FB on the Canvas:
1. Find the desired FB within the library (using scroll bars if present).
2. Click-and-drag the FB to the canvas.

Moving Function Blocks

To move a FB on the Canvas:
Click-and-drag the FB to the desired location on the canvas.
Hints:
Click the main body of the FB not one of its transmitters or receivers. Clicking a trans-
mitter or receiver begins to draw a signal rather than move the FB.
The canvas will scroll if the mouse pointer is close to the edge but not outside the dia-
gram window.
To make a long move, click the block to select it, then zoom out to make it easier to
move the block to the desired location.

Connecting Function Blocks Together

To connect a transmitter to a receiver:
Click and drag a signal from a FB's transmitter to a receiver on another FB.
Hint:
This can also be accomplished in reverse, i.e., click and drag from a receiver to a trans-
mitter.

Viewing Signal Values and Errors

To momentarily display a signal's value:
Mouse over (point the mouse cursor at) the signal.
To display a signal's value continuously:
1. Right-click the signal.
2. Click Show/Hide Data

 To cancel (turn off) the signal display:
1. Right-click the signal.
2. Click Show/Hide Data
Note:
The values displayed are not in real-time.

Troubleshooting Signal Errors

While building the FB diagram, or during operation, there may be occasions when the signal
from the transmitter of a FB is displayed yellow. This may reflect that the FB has encountered
an error or some other anomaly has occurred. From the user perspective, an evaluation of the
cause should be done to ensure that unexpected operation does not occur. Suggested steps to
evaluate the cause of a yellow link are listed below:
To evaluate the cause of a yellow signal:
1. Trace the yellow signal back to the source
(first occurrence of a yellow link) FB.
2. Place the mouse over the signal which
will display the error.
3. In this particular example, the error is identified as an Open sensor.
4. Click on the selected FB and view the Help window.
5. Search ("Ctrl-F") the help file for the word "Open".
6. Once found, evaluate, make note or correct the cause of the problem.
If further assistance is needed review the associated product User's Guides or contact the
Watlow Technical Support team (1-800-492-8569 or 1-507-494-5656).

Personalizing the User Interface (UI) Using Composer

The home screen of the F4T controller can be personalized to show multiple pages and mul-
tiple content blocks within each (4 maximum). Until personalized, the home screen will be
blank. Features that are available on
the Personalization screen are num-
bered corresponding to their associated
descriptions below:
Home screen can be modified in ac-
cordance with installed hardware
and named FBs on the FBD.
Modify user interface (UI) button col-
ors.
e Create a customized menu to be
viewed on the UI.
r Change the user interface screen brightness.
To personalize the home screen:
From the device menu choose Personalization from the drop down menu.
Much, if not all of what is displayed on the home pages comes from the FBD. Therefore, it
would make sense to first configure the FBD prior to personalizing the home screen.
The personalization settings shown above would produce a home page like the one below. Be-
cause it was the second page configured as shown above (red box), notice the arrow buttons
on the right and left of screen capture below allowing navigation to page 1 and 3.

Setting Up Data Log Files Using Composer

Data Logging can be enabled at any time and will log a user selectable list of data points.
While data logging is enabled, the data log file is stored within either the USB device memory
or internal memory. Once the file reaches a specified size (if being transferred automatically),
it will be sent directly to one of three other destinations (USB, TFTP server or a Samba serv-
er). The file transfer can also be initiated manually at any time. The file transfer process from
Watl ow F4T Controlle r 2 7 C h ap t er 2 C o n f ig u rat io n U sin g Co m p o s e r
 internal memory, whether completed automatically or manually, will move all log files from
internal memory to the selected destination. To learn more about data logging see "Data
Logging" in the Overview Section of this User Guide.
Note:
Data logging can also be enabled/configured through Modbus. There are specific Modbus
registers for each of the parameters defined below. If interested in identifying those regis-
ters, see the section entitled "Enabling Data Logging Using Modbus" in the Appendix of this
User's Guide.
Topics discussed in this section follow:
Setup Data Logging: discusses required fields that must be set prior to starting data logging.
Configuring a Samba Shared Folder: identifies and gives illustrations in defining the necessary
user account and the shared folder.
Configuring a TFTP Server: details required setup fields while illustrating steps to successfully
move files from the F4T to the TFTP destination.
Note:
Data logging is terminated when power is lost while the data log file itself will be main-
tained where it was captured.

Setup Data Logging

To setup data logging, follow the steps below:
1. Click on the Device Menu tab.
2. From the drop down menu click on Data Logging.
3. Select and add all of the desired Data Points for the data log file.
Note:
Selected data points will be used whenever data logging is enabled.
4. Click on the Setup button.
- Logging Status: indicates whether or not recording is active or not.
- File Name: any alphanumeric characters, 63 maximum.
Note:
When transferring files via TFTP, do not create a file on the server called "testfile".
Communications between the F4T and the TFTP server is tested prior to starting a
transfer using this filename while then verifying the response from the server.
- Log To: USB or Internal Memory.
Note:
When transferring files via TFTP or Samba, internal memory must be selected here.
Note:
There are many USB memory devices available. Watlow does not recommend using
micro SD or SD card to USB adapters in the USB slots. Be aware that we have not
tested all of the variations of USB memory devices but we have tested and validat-
ed those that are listed below:
Lexar, Kingston, Toshiba and Verbatim
Note:
Supported USB file systems: FAT16 and FAT32.
Wa tlow F4T Con trolle r 2 8 C h ap t er 2 C o n f ig u rat io n U sin g C om p o s e r
 Note:
Due to wear-leveling operations of flash memory devices (internal - F4T and exter-
nal - USB), there may be some gaps within the data logged file.
Note:
If logged file is sent to USB, the *.csv and the *.enc file are written directly to
USB constantly. If the File Size Limit is set to 10MB or larger, the csv will continue
to be written continuously while the encrypted portion (*.enc) is chunked into
7.5MB files, buffered internally and then written out as 7.5MB chunks. If the maxi-
mum file size is set to 10MB, there will be two *.enc files for each csv (7.5MB and
2.5MB). If File Size Limit is set to 15MB, there would be two 7.5MB *.enc files for
each *.csv file.
- Log Interval: defines the frequency in which the log will be written, 0.1 second to 60
minutes.
- File Type: Encrypted (filename.enc), comma separated values (filename.csv) or Both.
- File Size Limit: 20MB maximum when using internal memory, 1GB when using USB.
- Memory Full Action: when selected log to device is full, Overwrite or Stop.
Note:
Logging to USB allows for Stop only, when memory is full.
- Date Format: MM/DD/YYYY or DD/MM/YYYY.
Note:
Applies to each individual log entry alone, does not apply to filename.
- Time Format: 12 or 24 hour clock.
Note:
Applies to each individual log entry alone, does not apply to filename.
5. Click on the File Transfer button.
- Auto Transfer Type: None, TFTP, Samba or USB.
Note:
When automatic file transfer is enabled, the file as it's being created, will be buff-
ered in internal memory. The file will be moved to its destination when it either
reaches the maximum file size setting or the user stops data logging. If automatic
transfer fails for any reason, data logging will continue and the files will be stored
in internal memory until internal memory fills up. The setting for Memory Full Ac-
tion (Overwrite or Stop) will then be implemented.
Note:
A user can initiate a file transfer manually at any time if one or more of the avail-
able destinations (USB, TFTP or Samba) have been configured.
- Samba User Name: Windows user account name with access to shared directory.
Note:
If using Asian fonts, you may need to create a Latin character set login for use with
Samba transfers.
- Samba Password: Windows user account password.

Watl ow F4T Controlle r 2 9 C h ap t er 2 C o n f ig u rat io n U sin g Co m p o s e r

 Note:
If using Asian fonts, you may need to create a user, and password, using the Latin
character set.
- Samba Path: shared directory path and name.
Note:
If using Asian fonts in the path name, please try using latin characters, or numbers
as your folder name, and share name.
- Remote IP Address: the IP address of the remote computer.
- Remote Host Name: the name of the remote computer.
- Transfer Progress: when a transfer is initiated this will reflect its progress from 0% to
100%.

Configuring a Samba Shared Folder

Samba, also known as Server Message Block (SMB)/Common Internet File System (CIFS), is fully
supported by Windows File Sharing. Within this document, SMB/CIFS will be referred to as
Samba.
Samba, when in use, creates a directory on the F4T device that maps to a shared directory on
the users PC. There are several ways that a Windows shared drive can be configured. With
this is mind, one of those ways will be discussed and used for demonstration purposes below.
Note:
If a user account already exists with full Administrator rights, steps 1 through 12 can be
skipped.
Setting up a Windows shared drive:
1. Click the Windows Start button and type us-
er accounts in the search box.
2. When the Make changes to your user ac-
count window opens, click on Manage User
Accounts.
3. When the User Accounts window opens, click
on the Advance tab.
4. Under Advance user management, click on
the Advance button.
5. Under the Name column right-click on Users
and then New User.
6. In this example the new user will be identi-
fied as "Samba" and will be entered into the
User name field as shown to the right.

Watl ow F4T Controlle r 3 1 C h ap t er 2 C o n f ig u rat io n U sin g Co m p o s e r

 Note:
To ensure that there will be no changes required regarding the password, check Password
never expires.
7. Click on Create and then Close.
8. Click on the X (top right corner) to close the us-
ers window.
9. If not already open, navigate to Manage user ac-
counts and click on it. Once there, the new user
account should be visible as shown to the right.
10. Click the OK button.
11. Click on the X (top right corner) to close the Us-
er Account window.
12. Navigate to Windows Explorer and create a new
folder.
Note:
The name of the shared folder must not contain
any slashes, or back-slashes.
Note:
If the folder being created is a sub-folder off of
the root directory, right click on the created folder > select Properties > Sharing > Ad-
vanced Sharing and check Share this folder. Doing this will allow the sub-folder path to
be defined as if it were in the root directory of the selected domain. Lastly, click on Per-
missions and ensure that all boxes under Allow are checked as shown below.

13. Right-click on the folder created above and then mouse over Share with and click on Spe-
cific People.
14. Click on the drop down button and then Find people.
15. Enter the object name "Samba" and then click on the Check Names button.

Wa tlow F4T Con trolle r 3 2 C h ap t er 2 C o n f ig u rat io n U sin g C om p o s e r

 16. Click the OK button.
17. Click on the drop down button and ensure the folder is set for Read/Write capabilities as
shown below.

18. Click Share.

The graphic below shows the folder as being shared.

After the user account has been identified or created and the shared folder has been setup
it is time to configure the File Transfer function within the controller. The graphics below
show all fields that must be filled in to do an automatic transfer of the data logged file to the
shared folder identified in this example as SambaStore.
Note:
Transferring files via Samba may be accomplished by 2 methods; Auto-transfer, and a user
initiated transfer. Once the automatic transfer is enabled this function will move the file
to the remote computers shared folder whenever data logging is running and the set file
size has been reached. The graphics that follow illustrate automatic transfer.

Watl ow F4T Controlle r 3 3 C h ap t er 2 C o n f ig u rat io n U sin g Co m p o s e r

 First, a couple of fields (parameters) within Setup must be addressed, identified in the red
boxes below.
Log to - must be set to internal memory to automatically move the files to the shared folder.
File Size Limit - defines the maximum file size that will be moved to the shared drive.

Second, based on the example entries made above, the File Transfer fields need to be filled
in accordingly.

After these screens have been populated as shown, data logged files, once they reach approx-
imately 1MB in size, will be moved from internal memory to the shared folder (SambaStore).

Configuring a Trivial File Transfer Protocol (TFTP) Server

In order to use the TFTP file transfer option, a TFTP server must be setup and running on
your computer to service the TFTP transfers from the F4T. The user will need to specify the
IP address of the remote computer, and also the remote computer name.
TFTP requires no authentication and can transfer a file as large as 20MB to a remote host
computer. There are many TFTP servers available and many can be downloaded off the in-
ternet free of charge. To enable a TFTP transfer, within Composer or via the UI, simply enter
the IP address for the remote computer and ensure the TFTP server is running on the remote
computer.

Wa tlow F4T Con trolle r 3 4 C h ap t er 2 C o n f ig u rat io n U sin g C om p o s e r

 Configuring the TFTP Transfer:
1. Because there are several TFTP servers available note that naming may be different. What
is most important from the server standpoint is that the appropriate IP bindings are set
while the security allows for read/write capability as shown below.

2. Navigate back to the section entitled Setup Data Logging and follow the procedure to de-
fine what it is to be captured within the file. Within this same procedure (step 5), it will
be important to define the IP address of the remote computer while also determining
whether the file will be transferred manually or automatically.
3. Start the TFTP server and then start data logging by pushing the following buttons on the
F4T front panel: Main Menu > Data Logging > Start
If the file does not seem to be transferring as expected check out the parameter identified
above as Transfer Results and the table that follows it for some assistance.

Shows all currently existing steps for the selected profile (Oven 1).
A user can use "Add new step..." or use the buttons at the bottom to delete or insert a
step.
e Step Detail
Shows the current settings for the selected step while also allowing each to be modi-
fied.
The user has the ability to give the profile a name, apply password protection and en-
able data logging for this profile while running (red box above).

Profile Parameters
The following settings apply to the entire profile.

Wa tlow F4T Con trolle r 3 6 C h ap t er 2 C o n f ig u rat io n U sin g C om p o s e r

 Name
User-entered identifier for the profile. The name follows the profile when it is saved in a file
or moved to another controller.
Note:
If data logging is enabled for the profile it is suggested that the profile name be limited to
characters between A to Z, a to z or 0 to 9. The data log filename will replace any other
characters with an underscore ( _ ).

Password
User-set code that must be entered prior to editing a protected profile. A password may con-
sist of up to ten characters, may include letters, numbers or symbols and is case sensitive.

Guaranteed Soak Deviation/Guaranteed Soak Values: Loop1 to Loop4

The amount by which the process value is allowed to differ from the loops set point for steps
with Guaranteed Soak Enable set to On. In such steps when the process value differs from the
set point by more than this value, the step timer stops running until the process value is re-
turns to within the band defined by the set point plus or minus this value.

Step Parameters
The following parameters set the behavior of a profiles steps. Only the parameters that apply
to the selected step type appear in the step detail.

Step Type
Set the behavior of the step.
Options:
Soak: maintains the each loops set point constant for the steps Time.
Ramp Time: adjusts each loops set point gradually from the previous set point to the
steps Set Point over the steps Time.
Ramp Rate: adjusts each loops set point at the user-set Rate of change until it reaches
the steps Set Point.
Wait For Process or Event: holds the profile until the specified conditions on the event
inputs are met. When multiple conditions are specified, the profile will not proceed un-
til all the conditions are satisfied at the same time.
Instant Change: sets each loops set point to the steps Set Point without ramping from
the previous set point and holds that set point for the steps Time.
Jump: repeats previous steps in the profile starting at the step set with Jump to Step
for the Number of Times set. This option is not available for step 1. A value of zero en-
tered for the Number of Times will create an infinite loop.
End: sets what each loop and event output does when the profile ends.

Time: Hours Minutes Seconds

Set the duration of the step.
Note:
Step timing will be impacted if the a profile is running and the time settings are changed.

Watl ow F4T Controlle r 3 7 C h ap t er 2 C o n f ig u rat io n U sin g Co m p o s e r

 Ramp Rate
Set the speed at which the loops set point is increased or decreased to the steps Set Point
value.

Set Point
Set the value to which the loops set point is changed by the step.

Guaranteed Soak Enable

Set On to prevent step time from elapsing whenever the loops process value differs from its
Set Point by more than Guaranteed Soak Value for the loop.
Options: On, Off

Event Input 1 to Event Input 4

Set the condition on each input for a Wait for Process or Event step.
Options:
None: do not wait for this input.
On: wait until a digital input is on or true.
Off: wait until a digital input is off or false.
Greater Than: wait until the process value is greater than the setting of the corre-
sponding Input Value parameter.
Less Than: wait until the process value is less than the setting of the corresponding In-
put Value parameter.

Input 1 Value to Input 4 Value

Set the process value against which the corresponding analog input condition is evaluated in a
Wait for Process or Event step.

Jump To Step
Set the step at which the profile should begin to repeat steps.

Number of Times
Set the how many times the Jump Loop step repeats the previous profile steps.
Note:
Number of Times is the number of times the steps are repeated not including the time
they are executed prior to reaching the Jump step. For example if step 5 of a six step
profile is a Jump with Jump To Step set to 2 and Number of Times set to 1, when the pro-
file is run starting at step 1 it executes steps as follows: 1, 2, 3, 4, 5, 2, 3, 4, 5, 6.

Event Outputs: Event Output 1 to Event Output 4

Set the state to which the profile sets each event output at the start of the step.
Options:
On: the step sets the event output on or true.
Off: the step sets the event output off or false.
Unchanged: the step does not set the event output; it remains in whatever state was
previously set.

Wa tlow F4T Con trolle r 3 8 C h ap t er 2 C o n f ig u rat io n U sin g C om p o s e r

 End Action
Set what the control loop does after the profile is completed.
Options:
User: the loop controls at the Set Point setting prior to execution of the profile.
Off: the loop's control mode is set to Off.
Hold: the loop's Set Point is set to the last value used in the profile.
Note:
To anticipate and plan for expected control action at the end of a profile, an End step
should always be included as the last step in a profile. If not included within the profile,
a parameter within the control or cascade loop called "Profile End Action" will determine
which option above is active. End Action (if used within the profile), always takes prece-
dence over Profile End Action.

Event Driven Menus

During normal operation it is possible that an event can occur that will present the user with
indications, pop-up windows and menu selections that are not shown above. As an example,
if an alarm occurs the status bar (top of screen shot shown below) will indicate its existence
by blinking yellow. If the user pushes the status bar down button to view the alarm message,
and then pushes the alarm tab, menu options may appear (silence or clear) depending on the
alarm settings. A representative alarm display is shown below.

Watl ow F4T 4 3 C h ap t er 3 U sin g t h e F4 T Fro n t P a n e l

 As another example, if an input sensor opens, an error message will be displayed on the
screen requiring user intervention. Once the error is acknowledged (Dismiss), the status bar
will continue to blink red until the open sensor has been fixed. Once fixed, the status bar will
return to its normal operational display as shown below.

Navigation Keys and Displays

After initially powering up the controller a white initialization screen will appear first. Once
the startup process is complete the splash screen (shown below) will appear.

As described in the splash screen above...

After first time power-up, do the following:
1. Configure the controller using Composer software (see: Configuring Pluggable Flex Modules)
2. Using the Menu button setup the Home screen (see: Personalizing the Home Screen).
3. If the above steps have already been completed simply push the Done button to go to the
home screen.
The screen above will appear each time the controller power is cycled. If it is desired that the
splash screen no longer appear, check the box "Don't show this again" (shown in red box for
emphasis only).

Data Logging
Data Logging can be enabled at any time and will log a user selectable list of data points.
While data logging is enabled, the data log file is stored within either the USB device memory
or internal memory. Once the file reaches a specified size (if being transferred automatically),
it will be sent directly to one of three other destinations (USB, TFTP server or a Samba serv-
er). The file transfer can also be initiated manually at any time. The file transfer process from
internal memory, whether completed automatically or manually, will move all log files from
internal memory to the selected destination. To learn more about data logging see "Data
Logging" in the Overview Section of this User Guide.

 4 Chapter 4: Application Examples
Applications
This chapter contains the basic instructions for configuring sample applications. Refer to
Chapter 5 for detailed descriptions of the function blocks and parameters.

Single Loop Control

In this example, Universal Input 1 on module 1 measures the temperature of a chamber or
oven with a thermocouple. Control Loop 1 takes its feedback directly from the universal in-
put and signals output 2 on module 2 to switch the heater that heats the chamber or oven
accordingly.

Function Block Diagram

Watl ow F4T 5 8 C h ap t er 4 A p p licat io n E x a m p l e s

 Application Tips:
Loop blocks are initially located in the library and can be dragged to the canvas.
The signal from the universal input carries the process value to the PV receiver on the
loop block where it is used as feedback to the control algorithm.
The signal from HT on the loop to the output block controls the heater by signaling
when the heater should be on for on-off control or how much it should be on with a 0
to 100% signal for PID control.
Enter names for blocks where possible to make the application easier to understand.
Make sure the input blocks Sensor Type and other parameters are set correctly for
your sensor.
In the loop block set the Control Action and Heat Algorithm based on the type of load
being controlled.
If you use the PID algorithm, youll need to tune the loop for your system. For more in-
formation on autotuning see the section entitled "Autotune" in Chapter 5.
Depending on the type of output and the load it drives, you may be able to set Time
Base Type in the output block to Variable Time Base to improve control stability. Dont
use this setting with mechanical relays or switching devices or loads that are not purely
resistive.

Heat and Cool Control Loop

In this example Universal Input 1 on module 1 measures the temperature of an environmental
chamber with a thermocouple. Control Loop 1 takes its feedback directly from the universal
input, and uses output 2 on module 2 to heat the chamber and output 2 on module 1 to cool
the chamber as needed.

 Process Alarm
In this example Universal Input 1 on module 1 measures the temperature of a chamber or ov-
en with a thermocouple. Alarm 1 monitors the temperature from the universal input which is
also used by the control loop as feedback for heat control. When the temperature goes out-
side the normal range defined by the user-adjustable, alarm set points, output 1 on module 4,
a form C relay energizes an audible alarm and an indicator lamp to get the operators atten-
tion.

Function Block Diagram

Application Tips:
Alarm blocks are initially located in the library and can be dragged to the canvas.
The signal from the universal input to IN on the alarm is the one the alarm monitors
against the alarm set point.
The signal from the alarm to the output indicates when the alarm has occurred. The
alarm is indicated on the controller whether or not there is an output attached; the
output on the alarm block is for use with additional logic in the application diagram or
to drive external devices as is shown in this example.
Enter names for blocks where possible to make the application easier to understand.

Wa tlow F4T 6 1 C h ap t er 4 A p p licat io n E x a m p l e s

 The control loop is not necessary for the alarm; it is shown here just to make it clear
that more than one function block can receive the analog input signal.
Make sure the input blocks Sensor Type and other parameters are set correctly for
your sensor.
By default the alarms type setting is Off. Set it to Process Alarm.
Set the alarms Sides setting to High or Low if you want to monitor only for the pro-
cess value going too high or too low, or set Sides to Both if you want the alarm to occur
when the process value is either too high or too low.
For more information on alarm parameters see the section entitled "Alarm" in Chapter
5.

Deviation Alarm
In this example Universal Input 1 on module 1 measures the temperature of a chamber or ov-
en with a thermocouple. Alarm 1 monitors the temperature from the universal input which is
also used by the control loop as feedback for heat control. When the temperature gets farther
from set point than the user-adjustable, alarm set points, output 1 on module 4, a form C re-
lay energizes an audible alarm and an indicator lamp to get the operators attention.

Function Block Diagram

Watl ow F4T 6 2 C h ap t er 4 A p p licat io n E x a m p l e s

 Application Tips:
Alarm blocks are initially located in the library and can be dragged to the canvas.
The signal from the universal input to IN on the alarm is the one the alarm monitors
against the alarm set point.
The signal from CSP on the loop to CTR on the alarm transmits the loops set point to
the alarm so that the deviation alarms can be relative to the loops set point.
The signal from the alarm to the output indicates when the alarm has occurred. The
alarm is indicated on the controller whether or not there is an output attached; the
output on the alarm block is for use with additional logic in the application diagram or
to drive external devices as is shown in this example.
Enter names for blocks where possible to make the application easier to understand.
A deviation alarm uses the signal received at CTR as the center of the deviation band.
The high and low alarm set points are relative to that center value. In most devia-
tion alarm applications users want the alarm deviation centered on a control loops set
point as shown in this example, but any analog signal could be used.
Make sure the input blocks Sensor Type and other parameters are set correctly for
your sensor.
By default the alarms type setting is Off. Set it to Deviation Alarm.
Set the alarms Sides setting to High or Low if you want to monitor only for the pro-
cess value going too high or too low, or set Sides to Both if you want the alarm to occur
when the process value is either too high or too low.
For more information on alarm parameters see the section entitled "Alarm" in Chapter
5.

 Safety Limit
In this example one thermocouple measures the temperature of the chamber or oven provid-
ing feedback to a control loop that drives a heater with its heat output. A second thermocou-
ple connected to Temperature Input 1 on module 3 also measures the temperature but pro-
vides its signal to the limit function. The limit controls a form A relay output that is energized
when the temperature has not exceeded the safety limit setting and opens when the limit is
exceeded. The control loops output signal to the heater goes through the limit relay such that
power to the heater is cut off when the temperature is above the limit. Also a momentary
switch is connected to digital input 2 on module 3 so that the limit can be reset without using
the controller interface.

Function Block Diagram

Application Tips:
Because the limit option is designed for safety, the limit block is automatically present
on the diagram, and its input and output signals cannot be changed.
The signal from the digital input to the RST on the limit block allows a momentary
switch wired to that input to reset the limit alarm.

Watl ow F4T 6 4 C h ap t er 4 A p p licat io n E x a m p l e s

 The reset switch is optional. The limit can be reset using the controllers user inter-
face. Note that it is not considered good practice to locate a reset switch in a location
so remote from the equipment that the person resetting the limit cannot be sure it is
safe to do so.
Enter names for blocks where possible to make the application easier to understand.
Make sure the temperature input blocks Sensor Type and other parameters are set cor-
rectly for your sensor.
By default the limits Sides setting is Both. Set it to High or Low if you want to monitor
only for the process value going too high or too low, or leave it set to Both if you want
the limit to trip when the process value is either too high or too low.
Set the limit's Low Set Point and/or High Set Point to the values at which you want to
open the limit relays contacts.
Set the limit's Minimum Set Point and Maximum Set Point to the values above and below
which you do not want an operator to set the limit's Low Set Point and High Set Point.

Sensor Backup
In this example there are two thermocouples measuring the temperature of an oven. Normally
one provides feedback to a control loop that drives the heater. In the event the first thermo-
couple fails, the controller switches automatically to the second providing uninterrupted con-
trol.

 Application Tips:
Process blocks are initially located in the library and can be dragged to the canvas.
You can connect up to four sensors to the Process block. The process block passes along
the signal from the lowest number receiver that has no error on its sensor signal.
The signal transmitted by the process block can be used by a control loop or any other
function as if it was received directly from a universal input block.
Make sure the input blocks Sensor Type settings and other parameters are set correctly
for your sensors.
Set the Process blocks Function to Sensor Backup.

Profile Ramp and Soak

In this example the temperature of an environmental chamber is measured by a thermocouple
connected to Universal Input 1 on module 1 and controlled by a control loop with a heater
connected to output 2 on module 2. The chamber also has a door switch so the profile can
sense when the door is opened or closed and a test activation circuit to turn on parts that are
being tested at specific profile steps.

Function Block Diagram

Watl ow F4T 6 6 C h ap t er 4 A p p licat io n E x a m p l e s

 Application Tips:
The profile engine block is initially located in the library and can be dragged to the
canvas.
The signal from the input to PV1 on the profile engine lets the profile engine monitor
the process value when guaranteed soak is used and to establish the initial set point
when starting a profile.
The signal from SP1 on the profile engine to PSP on the control loop allows the profile
engine to control the loops set point.
If you want to be able to have a profile wait for a specific process value, connect the
process value signal to the EVT1 receiver (left side of the profile engine).
The door switch signal to EVT2 on the profile engine allows profiles to be programmed
to wait for the door to be open or closed.
The signal from the EVT1 transmitter (right side of the profile engine) to the test acti-
vation output allows the profile to enable an external circuit to power the parts under
test at the appropriate times.
Enter names for blocks where possible to make the application easier to understand.

Cascade Control
In this example a part is heated in an oven. The part takes a lot longer to heat up than the
heater and oven, and it can be damaged if heated so quickly that the temperature on the sur-
face is a lot higher than the interior temperature. To heat the part in the minimum amount of
time while protecting it from excessive thermal stress, two temperature sensors are used and
the controller is configured for cascade control.

 Function Block Diagram

Application Tips:
The cascade block is initially located in the library and can be dragged to the canvas.
The signal from the input for the part sensor to PVO on the cascade block lets the cas-
cade algorithm know the temperature of the part being heated and is used to deter-
mine the set point for the heater.
The signal from the input for the heater sensor to PVI on the cascade block is the feed-
back for the inner loop which controls the heater temperature.
The signal from HT on the cascade block to the output controls the heater.
Make sure the input blocks Sensor Type settings and other parameters are set correctly
for your sensors.
Set the Cascade blocks Function to Process.
Set Range Low and Range High settings to limit the heater temperatures to which the
part can be exposed. Setting Range Low to 50 and Range High to 210 means that when
the temperature in the part is low, the heater set point will go as high as 210, but as
the temperature inside the part increases, the heater set point drops.
In this example Control Action is set to Heat, the Inner Loop Heat Algorithm is set to
PID.
The Inner loop PID settings were set by using the auto tune feature, but the outer loop
PID settings were set manually for proportional only control with a proportional band of
20 so that the heater set point is proportional to how cool the part is.
If the oven must heat parts to many different temperatures or must heat parts over
a larger range of temperatures consider using the Deviation setting for the Cascade
blocks Function.
For more information on cascade control parameters see the section entitled "Cascade"
in Chapter 5.

 Compressor Control
In this example the temperature and humidity of an environmental chamber are controlled by
two loops. Loop 1 uses a heater to increase the temperature and a cooling coil to lower the
temperature. Loop 2 uses a solenoid to control water flow to an atomizer to raise the humid-
ity and a dehumidification coil to lower the humidity. The cooling and dehumidification coils
share a compressor. To minimize wear on the compressor and use of electricity, the compres-
sor is turned off and on by the controllers Special Output function block configured for com-
pressor control.

Function Block Diagram

Wa tlow F4T 6 9 C h ap t er 4 A p p licat io n E x a m p l e s

 Application Tips:
The special output block is initially located in the library and can be dragged to the
canvas.
The signals from the temperature and humidity loops PWR transmitters to A and B on
the special output block indicate the percent output power for each of the loops which
allow it to determine when the temperature and/or humidity loops need or may soon
need the compressor to be on.
The signal from OUT on the special output block signals when to turn on the compres-
sor.
Enter names for blocks where possible to make the application easier to understand.
Set the special outputs function parameter to Compressor Control.
Set the Minimum On Time and Minimum Off Time parameters long enough to protect
the compressor from too much cycling, but short enough to allow the compressor to
turn off between uses, for example 45 seconds for minimum on time and 15 seconds for
minimum off time.
Set Input A Turn On and Input B Turn On to the percent of power from the tempera-
ture and humidity loops at which you want the compressor to turn on so that it is ready
when the loop needs cooling or dehumidification, for example 0%.
Set Input A Turn Off and Input B Turn Off to the percent power at which you would be
comfortable having the compressor turn off, for example 2% for temperature and 5% for
humidity.
Note the correct settings for the parameters above depend on the specific application
hardware.
For more information on compressor control parameters see the section entitled "Com-
pressor Control" in Chapter 5.

F4T Functions Described
The controller is customized by connecting function blocks (FB) as needed for the application.
A transmitter of one function is commonly connected to a receiver of another using Com-
poser's function block diagram editor. The connections between blocks, referred to as signals,
carry information from one function block to another.
Each signal carries three pieces of information:
1. Value
The value is either analog
(floating point numbers) or
digital (on, off, true or false).
Most function blocks expect
a specific type of value to be
received at each receiver and produce a specific type of value at each transmitter.
Depending on the context, the value of a digital signal may be thought and spoken of
in various terms. The table below lists the various terms that occur in the various con-
texts.
Analog Value Digital Values Logic *Active Signal Parameter Settings
0% Off False Low
100% On True High
* When the state of a digital signal that triggers an action is configurable, the values are
referred to as Active and Inactive and a parameter is provided for choosing which state
triggers the action. As an example, if the TUN receiver in the graphic above is connected
to a digital device, the Loop 1 parameter "Initiate Autotune Active Level" (High or Low)
will determine when tuning occurs.
2. Units
An analog signal can be in units of absolute or relative temperature (Celsius or Fahr-
enheit), percent power or relative humidity. Values may have no units or unspecified
units, indicated as process. Digital signals have no units associated with them.
Units Description
The value is a temperature on the Celsius or Fahrenheit scale. For example,
Absolute 33 F as an absolute temperature is one degree above the freezing point
Temperature of water. An absolute temperature can be used as a set point or compared
with other temperatures to determine which is hotter or colder
The value is a relative number of degrees, not an absolute temperature.
For example, the difference between the two measured temperatures, 120
Relative
C and 100 C is 20 degrees, but it is not the temperature 20 C. A relative
Temperature
temperature is appropriate for use as a calibration offset or a deviation
alarm set point
Relative
The value is a measurement of percent relative humidity (%RH)
Humidity
The value is a percentage with 100% representing full power and 0% repre-
Power
senting no power
The value is in units of measure other than degrees Fahrenheit, degrees
Process
Celsius or relative humidity
None The value is a pure number without units

 3. Error Status
A signal's error status indicates whether or not the value can be relied on. A signal with
no errors (error status is none), is displayed as a black line in Composer. When some-
thing is wrong such that a function block cannot determine an appropriate value to
transmit, the signal is displayed as a yellow line in Composer. You can determine the
specific error status by mousing over the signal in the diagram. The table below lists
the possible errors that could be presented to the user. Any error status other than
none is considered an error.
Error Status Description
None No error is detected.
Open A sensor is broken or disconnected.
Shorted A sensor has failed or is shorted.
Measurement Error A measurement error has occurred.
Bad Calibration The controller has not been calibrated.
The ambient temperature is outside of the controller's operating
Ambient Error
range.
RTD Error An RTD sensor error has occurred.
Fail A measurement failure has occurred.
The source FB is missing a required signal at one of its receiv-
Not Sourced
ers.
Stale Data Data sourced from another controller has become unavailable.
Math Error A calculation has no defined result (such as divide by zero).

This chapter describes in detail each of the available functions as well as their associated pa-
rameters.
Note:
The addresses and other information required to read or set FB parameter values via a
field bus protocol is located in the "Communications" section of the Appendix to this Us-
er's Guide.

Alarm
Use an alarm to monitor an analog signal and set an output when that signal goes above or
below the user-set alarm conditions. This block is found in the Function Block Diagram edi-
tors Library when working with a controller that offers the Alarm block. The number of these
blocks available is shown within the parenthesis.

Use the Type parameter to set the blocks behavior. These options for Type are described in
detail in the following sections:
Off: no alarms occur. The blocks output is off.
Process Alarm: monitors an analog signal for specified alarm conditions.
Deviation Alarm: monitors an analog signal for alarm conditions relative to another signal.

 Off
When Type is set to Off, the output is off.

Process Alarm
A Process Alarm sets its output when the receiver (IN) rises above the High Set Point or drops
below the Low Set Point. The alarms behavior can be customized with Logic, Latching, Block-
ing, Silencing and Delay Time parameters.

Type
To monitor an analog signal for alarm conditions, set Type to Process Alarm.

Sides
Select whether the receiver (IN) is monitored for high, low or both high and low alarms.
Options:
Both: IN is monitored for high, low or both high and low alarms.
High: IN is monitored for a high alarm only. The low alarm is not monitored.
Low: IN is monitored for a low alarm only. The high alarm is not monitored.

Hysteresis
Set how far the process must return into the normal range before the alarm can be cleared.
Hysteresis defines how far the signal must drop below the High Alarm Set Point before a high
alarm can be cleared and how far the signal must rise above the Low Alarm Set Point before
a low alarm can be cleared.

Range: 1 to 9,999 F or units

2 to 5,555 C

Wa tlow F4T 76 C h ap t er 5 Fu n ct io n R ef e r e n c e
 Silencing
Set whether or not the output can be returned to the non-alarm state (silenced) before the
input returns to the normal range. Silencing an alarm returns the alarm's output to its inactive
state without requiring the alarm state to be cleared. Once the alarm is silenced, the output
remains inactive until the alarm is cleared and the alarm condition reoccurs.
Options:
Yes: alarm can be silenced by connecting a digital signal to SIL or by using the Silence
Alarm parameter
No: alarm cannot be silenced. After an alarm occurs, the functions output returns to
its non-alarm state only when the alarm is cleared

Latching
Select whether an alarm state is maintained (latched) or clears automatically when the pro-
cess value returns to an acceptable level.
Options:
Latching: alarm remains active until the condition that caused it no longer exists and
the alarm is reset by the CLR receiver or the Clear Alarm parameter.
Non-latching: alarm clears automatically once the condition that caused it no longer
exists.

Blocking
Alarm blocking allows a system to warm-up after being powered up or to be adjusted without
experiencing nuisance alarms. Set alarm blocking to prevent alarms before IN has first come
within the normal operating range.
Options:
Both: alarms are blocked when the controller powers up and deviation alarms are
blocked when the loop's Set Point or the alarm's High Set Point or Low Set Point is
changed.
Off: alarms are not blocked.
Set Point: deviation alarms are blocked when the loop's Set Point or the alarm's High
Set Point or Low Set Point is changed.
Startup: alarms are blocked when the controller powers up.

Display
Provides the ability to display alarm activity to the user interface (UI).
Options:
On: when an alarm is active will cause the controller status bar on the UI to flash yel-
low.
Off: when an alarm is active there will be no indication on the UI.

Watl ow F4T 77 C h ap t er 5 Fu n ct io n R e f e r e n c e
 Logic
Set which state (on or off) of the alarm function's transmitter indicates there is an alarm.
Options:
Close on Alarm: the alarm function's transmitter is off when there is no alarm and on
when there is an alarm.
Open on Alarm: the alarm function's transmitter is on when there is no alarm and off
when there is an alarm.

Delay Time
Set a length of time, in seconds, that an alarm condition must be present before the alarm
state and output are triggered. This setting determines the minimum time that the value at IN
must be continuously above the High Set Point or below the Low Set Point before the alarm
state and alarm functions output indicate an alarm. If the value at IN returns within the nor-
mal range before this time, no alarm occurs. This feature can be used to minimize nuisance
alarms.
Range: 0 to 9,999 seconds

Low Set Point

Set the process value or temperature that triggers the low process alarm.
Range: -99,999 to 99,999

High Set Point

Set the process value or temperature that triggers the high process alarm.
Range: -99,999 to 99,999

Clear Alarm
Set this parameter to clear to reset the alarm state after correcting the condition that caused
the alarm.
Options: Ignore, Clear

Silence Alarm
Set this parameter to silence alarms to deactivate the output after the alarm occurs.
Options: Ignore, Silence Alarms

Deviation Alarm
A Deviation Alarm's transmitter becomes active when the receiver (IN) rises above CTR (cen-
ter) by more than the High Set Point or drops below CTR by more than the Low Set Point. The
alarm conditions define a deviation window relative to CTR. CTR is typically connected to a
control loops set point so that when the control loops set point changes, the deviation alarm
window moves with it. The alarms behavior can be further customized with Logic, Latching,
Blocking, Silencing and Delay Time parameters.

This feature can be used to minimize nuisance alarms.
Range: 0 to 9,999 seconds

Low Set Point

Set how far the value at IN must drop below CTR to trigger a low deviation alarm. The low
deviation alarm occurs when the value at IN is below the centers value (CTR) plus this param-
eters setting. A negative value for Low Set Point sets the alarm condition below the center
and a positive value sets the alarm condition above the center.
Range: -99,999 to 99,999

High Set Point

Set how far the value at IN must rise above CTR to trigger a high deviation alarm. The high
deviation alarm occurs when the value at IN is above the centers value (CTR) plus this param-
eters setting. A negative value for High Set Point sets the alarm condition below the center
and a positive value sets the alarm condition above the center.

Error Handling Rules

When the alarm's receiver (IN) has an error the alarm is triggered. The Alarm function never
generates an error and the output's error status is always None.
Error Condition Result
Input has an error The Alarm State indicates there is an error and the output is active.

Analog Outputs
Use this block to operate an external device that takes an analog or process signal such as 4
to 20 mADC or 0 to 10 VDC.
These FBs are found on the canvas in the Function Block Diagram editor. The number of these
FBs available depends on the number of flex modules with analog outputs installed in the con-
troller.
These FBs can be used to operate a control element such as a proportional valve based on
the output of a control loop or to retransmit a signal proportional to a process value or set
point to another instrument such as a chart recorder. The illustrations below show examples
of these two uses. For a power output to a 4 to 20 mADC output, the value received is scaled
proportionally from the 0 to 100% input range to the 4 to 20 output scale. When the input is
25%, the output is 8 mADC.

For a retransmit output to a 0 to 10 VDC output, the value received at input In is scaled pro-
portionally from the 50 to 250 input range to the 0 to 10 output scale. When the input is
100, the output is 2.5 VDC.

Note that the settings of the Range Low and Range High settings do not limit the physical
output signal. The physical output is set according to the line defined by the range and scale
parameters and is limited by the range of values input to the function and the electrical limi-
tations of the hardware. If the input signal is limited to 0 to 100%, the Range Low is set to
0%, and the Range High is set to 100%, the output can be limited by setting the Scale Low and
Scale High parameters to the desired minimum and maximum signal levels.

Cascade
Cascade control can handle a difficult process with minimal overshoot, while reaching the set
point quickly. Using cascade control minimizes the possibility of causing damage to system
components and allows for over sizing heaters for optimal heat-up rates. Heater life is also ex-
tended by reducing thermal cycling of the heater. Systems with long lag times between the
energy source (heater, steam, etc.) and the measured controlled variable are very difficult to
control accurately and or efficiently with a single control loop. This is due primarily to a lot of
energy build-up before a response is detected. When using single loop control, the likelihood
of overshooting the set point is high, this overshoot can cause damage to the heater, product
or heat transfer medium such as a heat transfer fluid.
This block is found in the Function Block Diagram editors Library when working with a con-
troller that offers cascade control. The number of these FBs available is shown within the pa-
renthesis and is dependent on the controller part number.

When configuring the Cascade FB the user must select either Process or Deviation for the cas-
cade Function setting.

Process
When process is selected, the outer loop will compare the outer process variable (PVO) to its
set point. Based on the result of the comparison (error) the outer loop will generate a power
level. This power level will be converted and scaled to serve as the set point for the inner
loop. The range is defined by the user (y-axis) where the scaling (x-axis) is done automatically
based on whether or not the control action is set for heat, cool or both. As an example, in
the graph below for heat only, the user setting for Control Action would be heat with Range
Low set to 190 and Range High set to 210. In each graphic shown below, the solid line illus-
trates the proportional relationship between the scaling factors and the user defined range.
The resultant inner loop set point is displayed (dashed lines) before any filtering or offset is
applied.

Wa tlow F4T 84 C h ap t er 5 Fu n ct io n R ef e r e n c e
 Deviation
Deviation may be used instead of Process when it is desirable for the output range to be de-
fined relative to a value that might change frequently or automatically. For cascade control,
the outer loop will compare the outer process variable (PVO) to its set point. Based on the
result of the comparison (error), the outer loop will generate a power level. This power level
will be converted and scaled as an adjustment to the inner loop set point.
In the graphic below, the solid line illustrates the proportional relationship between the scal-
ing factors and the user defined range adjustment (-10 to +10) with the resultant inner loop
set point (dashed lines). Notice (in the graphic below) that with a user defined range of 10,
the inner loop set point will always be within the boundaries of 210 and 190. When the out-
er loop calculates a power of 75% that will generate an inner loop set point of 205.

remain between 91F and 97F. To control the process, two
loops of control are required along with two inputs; shown in

ly. The outer loop (PVO) monitors the controlled variable tem-
perature, which is then compared to its CLSP. The result of Heat/Cool

the comparison, the error signal, is conditioned by the PID PVI Inner Loop

settings and the Range high/low settings. Ultimately, the out- Power

er loop produces a remote set point for the inner loop. The PVO
Outer Loop

inner loop input (PVI) monitors the thermal medium, which is Remote SP

compared to the remote set point generated by the outer

loop. The result of the comparison, the error signal, is again conditioned by the PID settings in
the cascade inner loop and it will then generate an output power level between -100% to
+100%. If the power level is positive the heat will be on; if the power level is negative the
cool will come on. Power from the energy sources are supplied by the outputs of choice, al-
ways connected to the inner loop.
Note:
When cascade control is disabled via the FB receiver named Simple Set Point (SSP), the
input (PVO) and remote set point are virtually removed and the inner loop will now serve
as a single loop PID controller.

 Inner Loop Heat Algorithm
Set the method the control loop uses to set heat (HT) and power (PWR) outputs. For a given
application, on-off switches the output less frequently than PID, whereas PID maintains the
process value with much less cycling around set point than on-off.
For applications other than temperature control, use the heat output when there is an indi-
rect relationship between the input and the output, that is when the output should be in-
creased as the input drops below set point.
Options:
Off: no heat output is calculated or applied to HT or PWR
On/Off: On-Off control sets the HT and PWR to (100%) on, or off (0%)

PID: PID control sets the HT and PWR outputs to a value from 0% to 100%

Inner Loop Cool Algorithm

Set the method the control loop uses to set cool (CL) and power (PWR) outputs. For a given
application, on-off switches the output less frequently than PID, whereas PID maintains the
process value with much less cycling around set point than on-off.
For applications other than temperature control, use the cool output when there is a direct
relationship between the input and the output, that is when the output should be increased
as the input rises above set point.

 Options:
Off: no cool output is calculated or applied to CL or PWR outputs
On/Off: On-Off control sets the CL and PWR outputs on (100% for CL and -100% for

ing (100% for CL and -100% for PWR)

Inner Loop Deadband

Set the offset between the set point and the heat and cool proportional bands. A positive
deadband can reduce overshoot upon power up without changing the responsiveness of the
system at other times and prevents heating and cooling outputs from being on at the same
time. A negative deadband allows both the heat and cool outputs to be active around the set
point which can be of benefit when a process must be controlled near the ambient tempera-
ture.

 Cool Output Curve
Choose a cool output curve to set the responsiveness of the system. A nonlinear output curve
may improve performance when the systems response is
nonlinear. With the nonlinear curves, a given change in the
PID calculation at the lower part of the output range yields
a smaller change in the actual output level than a linear
output provides.
This feature is used in applications such as cooling of plas-
tic extruders where a small amount of water cooling has a
large effect initially, but diminishing returns as water flow
increases.
This parameter applies only when Cool Algorithm is set to
PID.
Options:
Off: the calculated PID value is applied linearly to the output.
Non-linear Curve 1: somewhat non-linear response such as with oil coolant.
Non-linear Curve 2: greater non-linear response such as with water coolant.

Profile End Action

Open Loop Detect Enable

Enable or disable the open-loop detect feature. When enabled, this feature monitors closed-
loop control for the appropriate process value response to the output signal. If the loop does
not respond as expected, the control mode is set to off.
Options:

PID Sets - Explained

This controller supports up to five heat/cool PID sets. This feature is extremely valuable if
the characteristics of your thermal system vary over its operating range. All PID sets can be
auto tuned or manually tuned and can also be configured to operate using any of the five sets
based on crossover points of the set point or process value. When the process or set point val-
ue crosses the crossover point, the PID set designated for that region of the operating range is
used to control the percent power being supplied to the load.
There is a -1 hysteresis for each crossover. A rising temperature will change PID sets at the
crossover value. A falling temperature will change PID sets at the crossover value -1.

Derivative Inner Loop [1 to 5]

Set how aggressively the derivative part of the PID algorithm acts. Derivative acts to prevent

 Autotune
When autotuning, the controller automatically selects the PID parameters for optimal control,
based on the thermal response of the system. Five sets of PID values are available. Default
PID values exist for all PID sets, although these values typically do not provide optimal con-
trol. PID values can be autotuned or adjusted manually.
When an autotune is started the current Set Point is used
to calculate the tuning set point. The controller will dis-
regard all set point changes until the tuning process is
complete. For example, if the active set point is 200 and
Autotune Set Point is set to 90 percent, the autotune func-
tion utilizes 180 for tuning.
Autotuning calculates the optimum heating and/or cool-
ing PID parameter settings based on the system's response.
Autotuning can be enabled whether or not TUNE-TUNE+
is enabled. The PID settings generated by the autotune
will be used until the autotune feature is rerun, the PID values are manually adjusted or
TRU-TUNE+ is enabled. You should not autotune while a profile is running. If the autotune
cannot be completed in 60 minutes, the autotune will time-out and the original settings will
take effect. The temperature must cross the Autotune Set Point five times to complete the
autotuning process. Once complete, the controller controls at the normal set point, using the
new parameters.
To initiate an autotune, follow the steps below:
1. Determine and set the operational Set Point
2. Set the Autotune Set Point (a percentage of the Set Point)
3. Connect and activate a digital signal to TUN (appropriate active level is required)
If need be, there are settings provided to adjust the tuning procedure's aggressiveness. Use
Autotune Aggressiveness. Select Under Damped to bring the process value to the set point
quickly. Select Over Damped to bring the process value to the set point with minimal over-
shoot. Select Critical Damped to balance a rapid response with minimal overshoot.
Set to start or stop automatically tuning the control loops PID parameters. This parameter ap-
plies when either Heat Algorithm or Cool Algorithm or both are set to PID.
Options:
No: if already started, aborts the autotuning process.
Yes: initiates the autotuning process.

application, on-off switches the output less frequently than PID, whereas PID maintains the
process value with much less cycling around set point than on-off.

 Dead Band
Set the offset between the set point and the heat and cool proportional bands. A positive
deadband can reduce overshoot upon power up without changing the responsiveness of the
system at other times and also prevents heating and cooling outputs from being on at the
same time. A negative deadband allows both the heat and cool outputs to be active around
the set point which can be of benefit when a process must be controlled near the ambient

Choose a cool output curve to set the responsiveness of the system. A nonlinear output curve
may improve performance when the systems response is nonlinear. With the nonlinear curves,
a given change in the PID calculation at the lower part of the output range yields a smaller
change in the actual output level than a linear output provides.
This feature is used in applications such as cooling of plastic extruders where a small amount
of water cooling has a large effect initially, but diminishing returns as water flow increases.

This parameter applies only when Cool Algorithm is set to PID.

PID Sets - Explained

This controller supports up to five heat/cool PID sets. This feature is extremely valuable if
the characteristics of your thermal system vary over its operating range. All PID sets can be
auto tuned or manually tuned and can also be configured to operate using any of the five sets
based on crossover points of the set point or process value. When the process or set point val-
ue crosses the crossover point, the PID set designated for that region of the operating range is
used to control the percent power being supplied to the load.
There is a -1 hysteresis for each crossover. A rising temperature will change PID sets at the
crossover value. A falling temperature will change PID sets at the crossover value -1.

Range: -99,000 to 99,999

Heat Proportional Band [1 to 5]

Set the proportional relationship between heat power (%) and the process value (typically
temperature). This setting determines how big a correction the proportional part of the PID
control algorithm makes when the process value deviates from set point. A smaller propor-
tional band yields a larger power adjustment for a given deviation from set point.
This parameter applies only when Heat Algorithm is set to PID. This parameter is set automat-
ically by autotuning the loop and when TRU-TUNE+ is enabled.
Range: 1 to 99,999 F or units
1 to 55,555 C

Cool Proportional Band [1 to 5]

Set the proportional relationship between cool power (%) and the process value (typically tem-
perature). This setting determines how big a correction the proportional part of the PID con-
trol algorithm makes when the process value deviates from set point. A smaller proportional
band yields a larger power adjustment for a given deviation from set point.
This parameter applies only when Cool Algorithm is set to PID. This parameter is set automati-
cally by autotuning the loop and when TRU-TUNE+ is enabled.
Range: 3 to 99,999 F or units
1 to 55,555 C

Integral [1 to 5]
Set how aggressively the integral part of the PID algorithm acts. Integral acts to drive the pro-
cess value to set point by steadily adjusting the output whenever the process value deviates
from the set point. A smaller Time Integral setting yields a larger power adjustment for a giv-
en deviation from set point over a given time.
This parameter applies when either Heat Algorithm or Cool Algorithm or both are set to PID.
This parameter is set automatically by autotuning the loop and when TRU-TUNE+ is enabled.
Range: 0 to 99,999 seconds per repeat

Watl ow F4T 111 C h ap t er 5 Fu n ct io n R e f e r e n c e

 Derivative [1 to 5]
Set how aggressively the derivative part of the PID algorithm acts. Derivative acts to prevent
the process value from changing too quickly. It can help minimize the effect of transient pro-
cess disturbances, but too much derivative can make the process slow to adjust to changes. A
greater Time Derivative setting yields a greater power adjustment for a given change.
This parameter applies when either Heat Algorithm or Cool Algorithm or both are set to PID.
This parameter is set automatically by autotuning the loop and when TRU-TUNE+ is enabled.
Range: 0 to 99,999 seconds

it starts at the Process Value and changes gradually to the Closed-Loop Set Point rather than
abruptly changing values.
Options:
Off: the loop controls to the Set Point immediately
Startup: each time the controller is powered up, the loop ramps the set point. At all
other times abrupt changes to the Set Point are allowed
Set Point: upon powering up the Set Point immediately resumes its last value, but the
loop ramps the set point each time the Set Point is changed

Use Idle Set Point Active Level below.
Range: Minimum Set Point to Maximum Set Point

Use Idle Set Point Active Level

Choose the signal value at the IDLE receiver which causes the loop to use the Idle Set Point.
Options:
High: the idle set point is used when the signal is on
Low: the idle set point is used when the signal is off

Remote Set Point

Choose whether or not the loop controls at the remote set point. The remote set point is re-
ceived on the control loops RSP input.
Options:
No: the loop does not use the remote set point for control
Yes: the loop uses the remote set point for control
Note:
Either the Remote Set Point parameter or the REN input can cause the remote set point
to override the loops set point.

Remote Set Point Type

Choose whether the remote set point received at input RSP overrides the Manual Power or
the Set Point when the remote set point feature is enabled by either the Remote Set Point
parameter or the REN input.
Options:
Manual: the remote set point is in percent power where -100% is full cooling, 0% is no
output and 100% is full heating and overrides the Manual Power when enabled
Auto: the remote set point is in the units of the PV input and overrides the Set Point

make the process value (input IN) equal to this setting.
Range: Minimum Set Point to Maximum Set Point

Manual Power
Set the desired output value for HT, CL and PWR outputs when Control Mode is Manual.
Range: Minimum Manual Power to Maximum Manual Power

Autotune Set Point

Set the percentage of the Set Point at which the loop autotunes. Because autotuning drives
the process value above and below the set point, in some applications it may be necessary or
preferable to autotune at a set point below or above the normal set point.
This parameter applies when either Heat Algorithm or Cool Algorithm or both are set to PID
and autotuning is performed.
Range: 50.0 to 200.0%

Autotune Aggressiveness
Choose the desired responsiveness for PID control after autotuning. This parameter applies
when either Heat Algorithm or Cool Algorithm or both are set to PID and autotuning is per-
formed.
Options:
Critical: balance a rapid response with minimal overshoot
Over: bring the process value to the set point with minimal overshoot
Under: bring the process value to the set point quickly tolerating overshoot

Autotune
When autotuning, the controller automatically selects
the PID parameters for optimal control, based on the
thermal response of the system. Five sets of PID val-
ues are available. Default PID values exist for all PID
sets, although these values typically do not provide
optimal control. PID values can be autotuned or ad-
justed manually.
When an autotune is started the current Set Point is
used to calculate the tuning set point. The controller
will disregard all set point changes until the tuning
process is complete. For example, if the active set

Wa tlow F4T 114 C h ap t er 5 Fu n ct io n R ef e r e n c e

 point is 200 and Autotune Set Point is set to 90 percent, the autotune function utilizes 180
for tuning.
Autotuning calculates the optimum heating and/or cooling PID parameter settings based on the
system's response. Autotuning can be enabled whether or not TUNE-TUNE+ is enabled. The
PID settings generated by the autotune will be used until the autotune feature is rerun, the
PID values are manually adjusted or TRU-TUNE+ is enabled. You should not autotune while a
profile is running. If the autotune cannot be completed in 60 minutes, the autotune will time-
out and the original settings will take effect. The temperature must cross the Autotune Set
Point five times to complete the autotuning process. Once complete, the controller controls at
the normal set point, using the new parameters.
To initiate an autotune, follow the steps below:
1. Determine and set the operational Set Point
2. Set the Autotune Set Point (a percentage of the Set Point)
3. Connect and activate a digital signal to TUN (appropriate active level is required)
If need be, there are settings provided to adjust the tuning procedure's aggressiveness. Use
Autotune Aggressiveness. Select Under Damped to bring the process value to the set point
quickly. Select over damped to bring the process value to the set point with minimal over-
shoot. Select critical damped to balance a rapid response with minimal overshoot.
Set to start or stop automatically tuning the control loops PID parameters. This parameter ap-
plies when either Heat Algorithm or Cool Algorithm or both are set to PID.
Options:
No: if already started, aborts the autotuning process.
Yes: initiates the autotuning process.

Counter Errors
If the CNT input has an error, the count will not increment or decrement. If the RST input has
an error, the count cannot be reset. An error on one input does not impact the operation of
the other input and its associated function. Regardless of errors on the inputs, the value of
the output is set according to the count and target values and the output never has an error.
The counter function never generates or propagates an error.

- RST has no error
- CNT has no error
The count increments or decrements normally but cannot be reset.

Current Input
This FB is found on the canvas of the FB diagram. The number of these FBs that are available
depends on the number of flex modules with current inputs installed.
Accurate current sensing requires that the controller's global AC Line Frequency be set to the
line frequency of current being measured and a current equal to or greater than 2 mA.
Note:
If an alarm is configured to monitor current as its source, the low alarm will be effective
only when the current level is equal to or greater than 2 mA. If there is no current pres-
ent, the low alarm will not be activated.
Use a current input to detect current flow in a load such as a heater and indicate a problem
if one were to occur, such as an open or short circuit.

Open and Shorted Load Circuit Detection

A Current Error can detect either an open or shorted load condition. A shorted condition
would be present if the control is calling for 0% power while current is detected as flowing
through the current transformer. Conversely, an open condition would be present when the
control is calling for power with no current flow detected through the transformer.
A Heater Error is used to determine if the load current flow is within the specified limits as
set by the user through the High Set Point and Low Set Point.

Units
Set the units of the output value.

temperature. For example, the difference between the two measured temperatures,
120 C and 100 C is 20 degrees, but it is not the temperature 20 C. A relative tem-
perature is appropriate for use as a calibration offset or a deviation alarm set point.

When the input has an error the signals connected to the output have the same error.
Error Condition Result

Logic
Use a logic block to set an output based on one or more digital signals. The logic block per-
forms logic operations on one or more inputs and sets its output based on the result.
This block is found in the Function Block Diagram editors Library when working with a con-
troller that offers the Logic block. Within the Library, the number of these blocks available is
shown in parenthesis.
Choose the logic operation with the Function parameter. These options for the Function pa-
rameter are described in detail in the following sections:
Off: the output is false.
And: If any input is false, the output is false. If all inputs are true, the output is true.
Nand: if any input is false, the output is true. If all inputs are true, the output is false.
Equal To: if all the inputs are false or all the inputs are true, the output is true. Otherwise,
the output is false.
Not Equal To: if all the inputs are false or all the inputs are true, the output is false. Other-
wise, the output is true.
Or: if any input is true, the output is true. If all inputs are false, the output is false.
Nor: if any input is true, the output is false. If all inputs are false, the output is true.
Latch: when the HOLD input is false, the output follows the IN input. When HOLD is true, the
output is held (latched) at the value it had when HOLD became true.
RS Flip Flop: one input sets the output true; the other sets it false.

The definition of the scaling line is very flexible. The input scale is not limited by the Scale
Low and Scale High values and the range of the scaling calculation is not limited to values be-
tween Range Low and Range High. Input values are converted according to the line defined by
the two points. Scale High need not be greater than Scale Low and Range High need not be
greater than Range Low. A filter and offset may be applied to the calculated value.
Process Scale can be used, for example, to convert from one set of units to another or to con-
vert a sensor signal to engineering units if the signal is linear with the value it represents.

Scale Low
Set the value of input X at which the Range Low setting is the desired result of scaling. Scale
Low and Range Low are the coordinates of a point on the line that relates input X to the
scaled output.

Set the value of input X at which the Range High setting is the desired result of scaling. Scale
High and Range High are the coordinates of a point on the line that relates input X to the
scaled output.
Range: -99,999.000 to 99,999.000

Units
Set the source units.
Options:
Source: when SW is on, the output has the same units as input X. When SW is off, the
output has the same units as input B.
None: the output value is a pure number without units
Absolute Temperature: the output value is a temperature value on the Celsius or Fahr-
enheit scale. For example, 33 F as an absolute temperature is one degree above the
freezing point of water. An absolute temperature can be used as a set point or com-
pared with other temperatures to determine which is hotter or colder.
Relative Temperature: the output is a value is a relative number of degrees, not an
absolute temperature. For example, the difference between the two measured tem-
peratures, 120 C and 100 C is 20 degrees, but it is not the temperature 20 C. A rela-
tive temperature is appropriate for use as a calibration offset or a deviation alarm set
point.
Power: the output value is a percentage signal where 100% represents full power and
0% represents no power.
Process: the output is in units of measure other than degrees Fahrenheit, degrees Cel-
sius or relative humidity.
Relative Humidity: the output is in percent relative humidity (%RH).

Range Low
Set the desired result of scaling at the point where input X equals the Scale Low setting.
Scale Low and Range Low are the coordinates of a point on the line that relates input X to the
scaled output.

 Filter
Set the amount of filtering to apply. Filtering smooths signal fluctuations. Increase the time to

Range: 0.0 to 60.0 seconds

Deviation Scale
When SW is off, the output equals the filtered, scaled value of input X plus DEV plus the off-
set. When SW is on, the output equals the filtered value of DEV plus the offset.
Scaling converts input X proportionally from the input scale to the output range according to
the line defined by the Scale Low, Scale High, Range Low and Range High settings as shown in
the illustration.

The definition of the scaling line is very flexible. The input scale is not limited by the Scale
Low and Scale High values and, the range of the scaling calculation is not limited to values be-
tween Range Low and Range High. Input values are converted according to the line defined by
the two points. Scale High need not be greater than Scale Low, and Range High need not be
greater than Range Low. A filter and offset may be applied to the calculated value. The out-
put has the same units as input DEV.
Deviation Scale may be used instead of Process Scale when it is desirable for the output range
to be defined relative to a value that might change frequently or automatically.

Profile
Use this block to configure how the profile features interact with control loops, physical inputs
and outputs and other application blocks. This block is found in the Function Block Diagram
editors Library when working with a controller that offers the Profile block. The number of
these blocks available is shown within the parenthesis.
Profiling is a feature that allows users to create time-based programs that, when run, change
control loop set points and output states automatically over time. The profile engine links the
controllers profiling feature with the inputs, outputs and other controller functions It provides
a way to integrate the use of profiles with the application as a whole.
Note:
After receivers PV1 - PV4 and EVT1 - EVT4 of the profile engine have been configured and
profiles have been created, any changes to those inputs will invalidate the existing profiles.
This is due to the fact that all input units (temperature, relative humidity, process, etc.)
must be compatible with the running profile. The profile invalidation will be graphically dis-
played in the profile editor with a yellow exclamation symbol . Changes are allowed to
the Profile Engine configuration for any of the other Inputs (PRF, STP, S/T, STRT, P/R, DIS)
or any of the outputs on the right side of the block without affecting the currently existing
profiles.

Note:
To learn more about using Modbus to define which profile will run, within the Appendix,

changes over the input range. At the low end of the range only A is considered. As the value

cant to the output until at the crossover point, the inputs are weighted equally, and the out-
put is the average of A and B. At the high end of the range only B is considered.

Special Output
Use this block to operate outputs for one of these applications: operating mechanical com-
pressors, controlling a motorized valve or sequencing multiple output devices to switch large
power loads. This FB is found in the Function Block Diagram editors Library. Within the Li-
brary, the number of these blocks available is shown in parenthesis and that number is deter-
mined by the controller part number.
Choose the algorithm with the Function parameter. These options for the Function parameter
are described in detail in the following sections:
Off: the first output follows the input all others are off.
Compressor Control: operates a compressor to meet demands for cooling or dehumidification
from one or two control loops while protecting it from excessive cycling.
Sequencer: operates a proportional power control and up to three on-off power controls as if
they were a single, larger, proportional controller.
Motorized Valve: operates a proportional valve without position feedback.

Off
The first output follows the input, all others are off.

Compressor Control
This function coordinates the demands of one or two control loops for a single compressor
and eliminates short cycling of the compressor. For example, when a compressor is used for
controlling an environment, a control loop may adjust a bypass valve proportionally to the
amount of cooling needed and another loop may adjust a valve proportionally for dehumidi-
fication. Both require the compressor to be on, but to save power and extend the life of the
compressor, it is desirable for the compressor to be off when it is not needed. The output
from this function turns the compressor on in anticipation of its use by either loop and turns
it off when it is not needed. The need for the compressor is anticipated by monitoring the
power outputs from the two loops (Input A for one loop and Input B for the second loop, if
used).
The diagram below illustrates how the compressor control functions for a single heat/cool
loop.
Compressor Settings:
Input A Turn On = -2%
Input A Turn Off = 2%
Minimum Off Time = 15 (sec)
Minimum On Time = 45 (sec)
Off Delay = 20 (sec)
Compressor Operation (Graphic Ex-
plained):
In this example, the power signal
from the temperature loop is con-
nected to Input A of the FB. When
the power signal drops below its
Turn On setting (-2%) and the Mini-
mum Off Time (15 sec) has been

Watl ow F4T 179 C h ap t er 5 Fu n ct io n R e f e r e n c e

 satisfied, the output to the compressor turns on immediately and will remain on until the
Minimum On Time is satisfied (45 sec).
w When the power level rises above 2% (Turn Off), the output to the compressor remains
on until the Off Delay is satisfied. Note that in this example the power level momentarily
drops below the 2% turn off, therefore the Off Delay is reset prior to reaching 20 seconds.
As soon as the power level rises to 2%, the Off Delay again starts; after 20 seconds the
output shuts off.
When the power signal drops below its Turn On setting (-2%) and the Minimum Off Time (15
sec) has been satisfied, the output to the compressor turns on immediately and will remain
on until the Minimum On Time is satisfied (45 sec). As soon as the power level rises to 2%,
the Off Delay again starts shutting the compressor off after 20 seconds.

The diagram below illustrates how the compressor control functions while coordinating the de-
mands from two control loops.
Compressor Settings:
Input A Turn On = 0%
Input B Turn On = -5%
Input A Turn Off = 2%
Input B Turn Off = 5%
Minimum On Time = 45 (sec)
Minimum Off Time = 15 (sec)
Off Delay = 5 (sec)
Compressor Operation (Graphic Explained):
In this example, the power signal from the humidity loop is connected to Input A and the
power signal from the temperature loop is connected to Input B. When the humidity signal
(A) drops below its Turn On setting (0%) and the Minimum Off Time has been satisfied, the
output to the compressor
turns on immediately.
w When the temperature
signal (B) drops below its
Turn On setting (-5%), the compressor is already on. When the humidify/dehumidify loop (A)
rises above its Turn Off (2%) the compressor remains on because it is still needed for the
temperature loop (Input B).
When Input B rises above 5% (Turn Off), the output to the compressor remains on for an
additional 5 seconds (Off Delay) to give the power signals time to stabilize. Notice that af-
ter the 5 second delay expires the output shuts off.
When Input B again drops below -5% (Turn On), the compressor turns on only after the
Minimum Off Time is met to minimize wear on the compressor. Again, Input B is calling for
the compressor to go off when it rises above 5%. In this case, the output will remain on
until the Minimum On Time of 45 seconds is satisfied plus the Off Delay (5 seconds). In the
event that Inputs A or B falls below their respective turn off percentages while the Off De-
lay is active, the Off Delay timer will reset as shown in the graphic above.
Once Input B rises above 5% the Off Delay timer is activated. When that time has been
satisfied the compressor goes off.

Function
To operate a compressor to meet demands for one or two control loops while protecting it

Input A Turn On
Set the value of the signal at receiver A that indicates demand for the compressor to turn on.
When A drops to or below this value and the Minimum Off Time condition has been met, the
function turns on the output to the compressor.
Range: -100.0 to 100.0%

Input A Turn Off

Set the value of the signal at receiver A that indicates there is no demand for the compressor
to be on. When A rises to or above this value and the Minimum On Time condition has been
met, the function turns off the output to the compressor.
Range: -100.0 to 100.0%

Input B Turn On
Set the value of the signal at receiver B that indicates demand for the compressor to turn on.
When B drops to or below this value and the Minimum Off Time condition has been met, the
function turns on the output to the compressor.
Range: -100.0 to 100.0%

Input B Turn Off

Set the value of the signal at receiver B that indicates there is no demand for the compressor
to be on. When B rises to or above this value and the Minimum On Time condition has been

Minimum On Time

 Off Delay
Set an amount of time the output signal remains on after the Minimum On Time is satisfied
and the signals at A and B indicate the compressor is no longer needed. This prevents the
compressor from turning off prematurely due to a transient condition such as opening a door.
Range: 0 to 9,999 seconds
Note:
During the Off Delay, if either channel's power signal drops below its turn off setting, the
compressor stays on and the Off Delay timer is reset. The timer starts again when A and B
are each above their Turn Off levels.
Time Delay
Set how long the compressor remains on while 0% power is received from the control loops.
This feature turns the compressor off when the power from the control loops is 0% for longer
than the Time Delay setting. Use the Time Delay to distinguish between the case where the
power is 0% because the loop is turned off, and the case where the power is 0% for a short
time when a loop switches from heating to cooling. To ensure the compressor stays on when
needed, but turns off when the control loops are off, set the Time Delay longer than the time
the loop outputs are at 0% in normal operation. If two loops are connected to the Special
Output function block, the Time Delay feature looks for both loops to output 0%. When the
Time Delay is set to 0, this feature is disabled.
Range: 0 to 9,999 seconds

Sequencer
This function coordinates a proportional output and up to three on-off outputs so that a large
amount of power may be controlled proportionally without the expense of a proportional
power control large enough to handle all the power at once.
The sequencer function takes a single input power signal and splits it up into four output
signals. Each output controls a portion of the total output power. The primary output, of-
ten referred to as the vernier output, operates a proportional power controller. The propor-
tional power controller must control the largest portion of the output. The other outputs are
contactors or other on-off power switches.

Timer
Use a timer when applications require timed control of outputs or a delay to an output for
a specific length of time. This block is found in the Function Block Diagram editors Library
when working with a controller that offers the Timer block.
The number of these blocks available to be added to the diagram is shown within the paren-
thesis.
Choose the type of timer with the Function parameter. These options for the Function param-
eter are described in detail in the following sections:
Off: disables the timer and holds the output is in its inactive state.
On Pulse: sets the output for a specified time.
Delay: switches the output a specified time after the input changes states.
One Shot: triggers the output by setting the time, timer counts down while the input is ac-
tive, output is active until time runs out.

When the Timer blocks function is set to Off, the transmitter is in its inactive state. See
Transmitter Active Level.

Function
To disable the timer and hold the output is in its inactive state, set Function to Off.

Transmitter Active Level

Choose the outputs active state. When Function is set to Off, the output is in the inactive
state, the opposite of the state selected here.
Options:
High: the timers output is off while the timer is disabled.

Low: the timers output is on while the timer is disabled.

On Pulse
This function produces an output pulse of a constant duration. This can be used as a mini-
mum on time for devices that do not tolerate excessive cycling.
To understand the timers behavior, consider these scenarios illustrated in the timing diagram
below:
1. When input changes to its active state, the function sets the output to its active state and
begins accumulating the elapsed time. Once the elapsed time reaches the value set for
the Time parameter, the output returns to its in-
active state and the elapsed time resets to zero.
2. The input need not stay active for the output to
remain active for the specified time.
3. However, while the timer is running, if the input
becomes inactive and then active again, the pulse
length is increased.

Note:
The active and inactive states are user configurable with the parameters described below.
Therefore, the description of the timers behavior for its inputs and outputs refers to the
active and inactive states for each rather than on or off. For example, if the inputs ac-
tive state is set to High, the timer starts running (becomes active) when the input changes
from low (off) to high (on). However, if the inputs active state is set to Low, the timer
starts running (becomes active) when the input changes from high (on) to low (off).

the timer is not running, Elapsed Time reads zero.
Range: 0 to 99,999.000
Note:
The elapsed time is not retained through a power loss; it is set to zero upon power up.

Watl ow F4T 191 C h ap t er 5 Fu n ct io n R e f e r e n c e

 Delay
The output follows the input, but only after the input is present for at least the specified
time. This can be used to keep short input pulses from propagating through to logic or an out-
put. It can also be used to trigger a secondary action following a primary action and a specif-
ic time delay, such as, turning on successive output devices. The timer can be configured as
an on-delay or off-delay by setting the Active State and Active Level parameters appropriately.
To understand the timers behavior, consider these scenarios illustrated in the timing diagram
below:
1. When the input changes to its active state, the elapsed
time begins to increment. Once the elapsed time reach-
es the value set for the Time parameter, the output
changes to its active state and the elapsed time holds.
When the input changes back to its inactive state, the
output returns to its inactive state and the elapsed
time resets to zero.
2. If the input is active for less than the Time setting, the
output never becomes active.
Note:
The active and inactive states are user configurable with the parameters described below.
Therefore, the description of the timers behavior for its inputs and outputs refers to the
active and inactive states for each rather than on or off. For example, if the inputs ac-
tive state is set to High, the timer starts running (becomes active) when the input changes
from low (off) to high (on). However, if the inputs active state is set to Low, the timer
starts running (becomes active) when the input changes from high (on) to low (off).

 Transmitter Active Level

Options:

Low: Off

Elapsed Time
Indicates the amount of time since the input became active up to the value set with the Time
parameter, then holds at that value until the input becomes inactive. When the input be-
comes inactive, Elapsed Time is reset to zero.
Range: 0 to 99,999.000
Note:
The elapsed time is not retained through a power loss; it is set to zero upon power up.

One Shot
The One Shot timer behaves like an analog oven timer. The user sets the time and the timer
counts down to zero without retaining the original time (hence the name one-shot). The out-
put is active whenever the time is greater than zero, and the timer counts down while the in-
put is active until the time reaches zero. This can be used in applications where the user may
set a different time each time the process runs.
To understand the timers behavior, consider these scenarios illustrated in the timing diagram
below:
1. If the input is active when the time is set by the user, the output becomes active and the
timer starts counting down immediately. The Time parameter counts down and Elapsed
Time counts up until Time reaches zero and Elapsed
Time reaches the value initially set for Time by the
user. Once the time has elapsed, the output becomes
inactive and the Elapsed Time resets to zero.
2. If the input is not active when the user sets the time,
the output becomes active, but the timer does not run.
When the input becomes active, the output remains ac-
tive until the timer counts down to zero. If the input
becomes inactive at any point while the timer is run-
ning, the output remains active and the Time and Elapsed Time hold until the input be-
comes active again at which point the timer resumes running.
Note:
The active and inactive states are user configurable with the parameters described below.
Therefore, the description of the timers behavior for its inputs and outputs refers to the
active and inactive states for each rather than on or off. For example, if the inputs ac-
tive state is set to High, the timer starts running (becomes active) when the input changes
from low (off) to high (on). However, if the inputs active state is set to Low, the timer
starts running (becomes active) when the input changes from high (on) to low (off).

 Retentive
A retentive timer is used to keep track of how much cumulative time the input has been ac-
tive. For example, it can be used to time how long an alarm is on over the course of a day.
The output can be used to trigger an event if the elapsed time is considered excessive.
To understand the timers behavior consider these scenarios illustrated in the timing diagram
below
1. While the RUN input is active, the elapsed time counts up. Whenever RUN is inactive, the
elapsed time holds. When the elapsed time reaches the specified time, the output be-
comes active and remains active until the timer is re-
set. When the RST input becomes active, the output
becomes inactive and the elapsed time is reset to zero.
2. If RST becomes active while the timer is running, the
timer stops and the elapsed time is reset to zero.
Note:
The elapsed time increments whenever the input is ac-
tive and the reset is not, even if it exceeds the Time
parameter setting.
Note:
The active and inactive states are user configurable with the parameters described below.
Therefore, the description of the timers behavior for its inputs and outputs refers to the
active and inactive states for each rather than on or off. For example, if the inputs ac-
tive state is set to High, the timer starts running (becomes active) when the input changes
from low (off to high (on). However, if the inputs active state is set to Low, the timer
starts running (becomes active) when the input changes from high (on) to low (off).

About the Universal Input

The Universal Input block scales the electrical signal received by the analog input hardware to
a process value that can be used by other blocks such as a control loop or alarm. If the signal
is from a thermocouple or RTD, once the Sensor Type, TC Linearization and RTD Leads param-
eters are set, the block scales the signal to an absolute temperature with no other configura-
tion required.
Note:
Flex Modules can be ordered as Mixed I/O or High Density (HD) I/O. When HD modules are
in use, the pinouts on the card are slightly different than Mixed I/O modules. Pinouts and
the associated graphics are displayed for both.
Note:
Although the functionality and parameters for any given sensor type does not change with
the selected Units, the graphic does. In the following descriptions, the associated graphics
for the sensor type will be displayed for the selected units.

Scaling Voltage and Current Inputs to Process Units

If the signal is from a device that outputs a voltage or current proportional to the process val-
ue, set the Sensor Type, Units, Scale Low, Scale High, Range Low and Range High parameters
to present the process value in the appropriate units. Scale Low and Range Low are the coor-
dinates of one point and Scale High and Range High are the coordinates of another point de-
fining the line relating the electrical signal to the conditioned process value produced by this
block. See the figure below.
For example, a flow meter is connected to the universal input. The flow meter provides a cur-
rent signal proportional to flow where 4 mA indicates 0
gallons per minute (gpm) and 20 mA indicates 10 gpm.
With the scaling parameters set as listed below, when the
universal input receives an 8 mA signal, the output of the
block is 2.5 (gpm).
Sensor Type: Milliamps
Units: Process
Scale Low: 4 mA
Scale High: 20 mA
Range Low: 0 (gpm)
Range High: 10 (gpm)

Millivolts/Volts
These FBs are found on the canvas of the FB diagram. The number of these FBs that are avail-
able depends on the number of flex modules with Universal Inputs installed and configured for

to be added to the diagram is shown within the parenthesis.
Choose the type of variable with the Data Type parameter. These options for the Data Type
parameter are described in detail in the following sections:
Analog: variable holds a user-set, analog value for use as an input to another block.
Digital: variable holds a user-set, digital or Boolean state for use as an input to another block.

Analog
Power: Use this function to integrate a user-set, power level or percentage in to the
application. When the Data Type is Analog and Units is Power, the Variable function ap-
pears as shown at the left.
Note:
When used as the input to the control loop FB, a profile will run in manual mode.
When the profile is not running, the control loop will run in the user defined mode.

Communications
The F4T controller is equipped with Modbus TCP and Standard Commands for Programmable
Instruments as embedded protocols.

Introduction to Standard Commands for Programmable Instruments (SCPI)

This protocol was originally designed in the 1960s by Hewlett-Packard using the IEEE 488
standard (8-bit parallel bus) and was created for the primary purpose of allowing comput-
ers to talk with programmable instrumentation. SCPI commands are ASCII text strings with a
wide array of defined SCPI commands, all of which are not included in this implementation.
Although the SCPI protocol can be deployed over multiple physical layers Watlow has imple-
mented this protocol over Ethernet port 502. The available SCPI commands are shown below:
1. :SOURCE:CLOOP#:PVALUE? - reads the process value for a control loop
- Example :SOURCE:CLOOP2:PVALUE? - read the process value from control loop 2
2. :SOURCE:CLOOP#:SPOINT? - reads the set point for a control loop
- Example :SOURCE:CLOOP1:SPOINT? - read the set point from control loop 1
3. :SOURCE:CLOOP#:SPOINT <value> - set the set point for a control loop
- Example :SOURCE:CLOOP2:SPOINT 75 - set the set point for control loop 2 to 75
4. :SOURCE:CLOOP#:RTIME? - reads the ramp time for a control loop where # is the control
loop instance
- Example :SOURCE:CLOOP1:RTIME? - read the ramp time for control loop 1

- Example :SOURCE:CLOOP1:RSCALE HOURS set the ramp time units to hours for con-
trol loop 1
8. :SOURce:CLOop#:RACTion OFF - Set the control loop ramping off (where # is the control
loop instance)
- Example :SOURCE:CLOOP3:RACTION OFF set ramping off for control loop 3
9. :SOURce:CLOop#:RACTion STArtup - Set the control loop to ramp the set point when the
controller powers on(where # is the control loop instance)
- Example :SOURCE:CLOOP4:RACTION STARTUP set ramping on at start up for control
loop 4

 10. :SOURce:CLOop#:RACTion SETPoint - Set the control loop to ramp the set point when the
set point is changed (where # is the control loop instance)

- Example :OUTPUT2:STATE OFF set event output 2 off
14. :OUTPut#:STATe ON - Set the event output on where # is the output number (1-8)
- Example :OUTPUT3:STATE ON set event output 3 on

- Example :PROGRAM:SELECTED:NUMBER 1 set the current profile to profile number 1
16. :PROGram:SELected:NAME? - Query the current profile name

Introduction to the Modbus Protocol

Gould Modicon, now called AEG Schneider, first created the protocol Referred to as Modbus
RTU used in process control systems. Modbus provides the advantage of being extremely reli-
able in exchanging information, a highly desirable feature for industrial data communications.
This protocol works on the principle of packet exchanges. The packet contains the address of
the controller to receive the information, a command field that says what is to be done with
the information, and several fields of data. Each F4T parameter has a unique Modbus address
and they can be found in the table below.
All Modbus registers are 16-bits and are listed in the following table as relative addresses (ac-
tual). Some F4T parameters are contained within 32 bits (IEEE float, signed 32 bit), notice that
only one (low order) of the two registers is listed. By default, the low order word contains the
two low bytes of the 32-bit parameter. As an example, in the table below find the Universal
Input and then take a close look at the first member (Analog Input Value). Note that it lists
register 27586. Because this parameter is a float, it is actually represented by registers 27586
(low order bytes) and 27587 (high order bytes) as stated above. The Modbus specification does
not dictate which register should be high or low order therefore, Watlow provides the user the
ability to swap this order.

Watl ow F4T 212 C h ap t er 6 Ap p e n d i x

 Note:
For the purpose of making an easy transition from the F4 to the F4T controller using
Modbus, a special set of the most commonly used F4 registers were created. Notice that
there are two tables of Modbus registers, they are unique sets of registers (not inter-
changeable) and the user must select one set or the other when implementing using
Modbus.
Map 1 = F4T registers (default)
Map 2 = Limited set of F4 compatible registers
To change the Modbus mapping using the F4T front panel:
1. From any screen, push the Menu button
2. Push the Settings button and then the Network button
3. Select the Ethernet communications channel
4. Scroll the screen down to find Data Map and select 1 or 2.

Enabling Data Logging Using Modbus

To enable data logging when using the Modbus communications protocol:
1. Load Modbus register 18888 (Profile Active File Number) with the desired profile number
(1 to 40).
2. Load Modbus register 19038 "Log Data" with 106 (yes).
3. Write Modbus registers to the controller.
Or
Manually enabling data logging (outside of a profile)
1. Think about and modify the following Modbus registers if need be:
- Memory Full Action, Modbus register 42350 [Stop or Overwrite]
- File Size Limit, Modbus register 42372 [20 MB or 1/4 of the available memory]
- Log Interval, Modbus register 42388 [0.1, 0.2, 0.5, 1, 2, 5, 10, 15 and 30 seconds, 1, 2,
5, 10, 15, 30 and 60 minutes]
2. Load Modbus register 42386 "Log Action" with 1782 [start].
3. Write Modbus registers to the controller.
Note:
To see a full listing of data log Modbus registers and associated enumerated values, navi-
gate to the table section entitled "Logging".

Using Modbus to Determine Profile Selection

It is important to know that when creating profiles an index is assigned to each in the order
in which they were created. When defining which profile to run through Modbus it is most im-
portant to understand how the indexing works.
The actual number of profiles within a controller and the index for each can be easily identi-
fied through 41 unique Modbus registers beginning at 48000 (Profile List Count) and a unique
List Member for each profile. If the list of profiles is created once without deletion of any of
those profiles, the List Member Modbus register for any given index will not change. However,
if any profiles are deleted after original creation, the List Members and index values for those
following the deletion point will be modified (shifted up in the profile listing). In the example

Wa tlow F4T 213 C h ap t er 6 A p p e n d i x

 that follows, 6 profiles have been created with given names shown to the left and the associ-
ated Modbus registers (Profile List Member) displayed with index values to the right. With the
profile listing as shown below, Modbus register 48000 (Profile List Count) would be equal to 6.
Profile Listing As Originally Created
Profile Listing (as viewed in controller) Profile List Member - Modbus Registers
Heat Only 48002 = 1
Heat/Cool 48004 = 2
Blk Furnace 48006 = 3
Part Chamber 48008 = 4
Part Cool Down 48010 = 5
Roaster 48012 = 6

To load and run "Part Cool Down" above, the value of 5 would be written to Modbus register
16558 (Start Profile) while then writing 1782 (start) to register 16562 (Profile Action Request).

If the profile listing were modified where Profile 3 is deleted, note the changes in the table
below for the profile listing and associated Profile List Member - Modbus registers.
Profile Listing After Changes

Note that all of the profiles following the deletion point where shifted up (name and index
value) and Modbus register 48000 (Profile List Count) would now be equal to 5. Notice that
for the same profile mentioned above (Part Cool Down) the index did not change but it was
moved from List Member 5 to 4 where index 3 no longer exists.

Modbus Table Orientation

In the tables that follow, each page will contain a header that describes available parameters
and their associated Modbus addresses. Further explanation can be found below. When en-
countered throughout this document, the word "default" implies as shipped from the factory.

Parameter Name - identifies the member name within a particular function.

Range - Defines options available for this prompt, i.e., min/max values (numerical), yes/no,
etc... (further explanation below).
Default - Values as delivered from the factory.
r Data Type and Access (R/W) - Unsigned 16 bit integer, Signed 32-bit, long, string = ASCII (8
bits per character), float = IEEE 754 32-bit, RW = Readable, Writable

 t Modbus Relative Address - Identifies unique parameters addresses using either the Modbus
RTU or Modbus TCP protocols (further explanation below).

Range
Within this column notice that on occasion there will be numbers found within parenthesis.
These numbers represent the enumerated value for that particular selection. Over Modbus,
range selections can be made simply by writing the enumerated value of choice to the desired
parameter. As an example, find the Sensor Type under the Universal Input. To turn the sen-
sor off using Modbus, simply write the value of 62 (off) to register 27594 (if in slot 1) and send
that value to the controller.

Modbus Relative Address

Within this column the listed address can also be referred to as the base address. To deter-
mine the address of any given member within a particular function see the example below.
To read the third thermocouple value from a Universal Input module (FMHA-RAAA-AAAA, High
Density I/O) that is placed in slot 5 of the controller follow the steps below:
1. Find the Universal Input and locate the Analog Input Value.
2. Identify the slot (module) in which the module resides and its associated base address
(base address is displayed for each module/slot).
3. Note offset (red arrow) to the next Modbus address from the base, in this case 110.
4. Multiply the displayed offset by two and add that to the base number (110 x 2) + 29346).
