 A Conceptual View of the RM System
The flexibility of the RM family modules and software allows for a large range of configura-
tions. Acquiring a better understanding of the application requirements and then the overall
functionality and capabilities of each RM module will help to ensure maximum system perfor-
mance.
The RM system at a high level can have a total of 17 modules installed, only one of which
can be an RMA module and the others (16 maximum) can be any combination of available RM
modules. Each installed RM module must have a unique Standard Bus address (factory default
for an RMA is J while all other RM modules would be 1) ranging from 1-я, A-F (10 -15) and h
(16). Default zone addresses can be changed on any RM module using the button on the face
of each module. Ensure that each module has a unique address.
The RMA can be considered an accessory RM module in that by itself it has no PID control
loops. However, used in conjunction with an RM Control (RMC), RM High Density (RMH) or
an RM Expansion (RME) module, it could be placed in a remote location up to 200 feet away
from any of the other RM modules on the network. While in a remote location, the RMA is
still fully capable of using all of its features, such as, the real time clock (used with profiles)
and data logging. This can be done while also providing communications to / from a master
device on the fieldbus network.
Some of the user selectable ordering options are listed below:
1. Class 2 or SELV (Saftey Extra Low Voltage) equivalent Power Supplies:
• 90-264 Vac to 24Vdc @ 31 watts
• 90-264 Vac to 24Vdc @ 60 watts
• 90-264 Vac to 24Vdc @ 91 watts
2. The RMA Module can provide:
• Multiple field bus protocols
• Data logging capabilities (up to 200 data points)
• Real Time Clock with Battery Backup
• Automatically (upon power restoration) re-enable a profile to run after a power loss
• Auto-Configuration Backup
Note:
All RM modules can share data over the backplane (local and split rail). Once the system is
configured and running, changing zone addresses without careful deliberation may cause
disruption in operation.

RM System Configurations Using and RMA

Due to the scalability and flexibility in the system components a user has several options
available in the way that the hardware can be connected.

 Module Orientation
The picture below reflects a front view of an RMA module. Like all RM modules, there are
four slots that appear on the face (slot A, B, D, and E) of the module and one on the bottom
(slot C) not shown. For this particular module only slots D and E can be used. On the face of
the module there is a button (orange circle) under the Zone address J that when pushed and
held has the following function:
1. Push and hold for ~ 2 seconds to change the Zone address. Valid addresses range from 1
to 17 (1 - я, a is 10, b is 11, C is 12, d is 13, E is 14, f is 15, and h is 16). The Access
module is shipped (default factory address) at address J or 17

Note:
For correct operation and accuracy, the module must be mounted in a vertical orientation
as shown.

 RM Installation and Removal on a DIN Rail
Modular Backplane Connector
The picture on the right shows the Modular Backplane Connector, both front and rear view.
The rear view is bringing in to focus a metal clip. If the DIN rail is grounded the Modular
Backplane Connector and the module connected to it will be also (recommended).

Installing the Modular Backplane Connector

To install the backplane follow the steps below:
1. Hook backplane assembly to upper edge of DIN rail, (see rear view above, backplane hook
detail that mates with upper rail edge is circled)
2. Next, rotate back plane assembly downward to engage the lower edge of the rail.
Note:
Din Rail clipping distance ranges from
1.366 -1.389 inches. The back plane
assembly will not latch onto the rail
successfully if the rail is out of dimen-
sion.
3. For final positioning and locking, the
red tab is to be pushed upward to fur-
ther engage the bottom edge of the
rail with an over center snap action
latch. (The red locking tab protrudes
from the bottom side of the back
plane assembly).

Note:
For easy removal and placement of modules it is recommended that there be a 76.2 mm
(3.00 in) clearance on the top, bottom and front of each module.

Watlow EZ-ZONE ® RMA Module • 14 • Chapter 2 Install and Wire

 Installing Multiple Modular Backplane Connectors
Multiple modules are easily aligned and latched together. Each module includes matched
mating geometry that facilitates accurate and consistent interconnections.
To install backplane connectors follow the steps below:
1. Attach individual modules to the rail sepa-
rately.
2. Laterally slide the modules together until
they touch.
3. When the multi-module system is attached
and laterally positioned to the desired place-
ment the locking tab should be engaged to
secure the control system to the rail.

Module Installation
In the picture to the right notice that the arrow
is pointing at the top lip of the module (on side).
To install modules on the backplane follow the steps below:
1. Slide the lip of the module over the top of the Modular Backplane Connector and then
push down on the rear of the module. The module will then slide over the two posts just
above the green connector (see pictures below).

 Connecting and Wiring the Modules
RM System Connections
Components of a RM system can be installed as stand alone modules or can be interconnect-
ed on the DIN rail as shown below. When modules are connected together, power and com-
munications are shared between modules over the modular backplane interconnection.
Therefore, bringing the necessary power and communications Modular Backplane Interconnect
wiring to any one connector in slot C is sufficient. The modular
backplane interconnect comes standard with every module
ordered and is generic in nature, meaning any of the RM mod-
ules shown below on the DIN rail can use it.
Notice in the split rail system diagram that a single power sup-
ply is being used across both DIN rails. One notable consider-
ation when designing the hardware layout would be the avail-
able power supplied and the loading affect of all of the modules
used. Watlow provides three options for power supplies listed below:
1. 90-264 Vac to 24Vdc @ 31 watts (Part #: 0847-0299-0000)
2. 90-264 Vac to 24Vdc @ 60 watts (Part #: 0847-0300-0000)
3. 90-264 Vac to 24Vdc @ 91 watts (Part #: 0847-0301-0000)
With regards to the modular loading affect, maximum power for each is listed below:
1. RMCxxxxxxxxxxxx @ 7 watts
RM Controller RM Expansion RM Access
2. RMEx-xxxx-xxxx @ 7 watts Module Module Module

some assumptions pertaining to the split
rail system diagram shown below. The

power supply used is the 91W supply. EZKB - _ A_ _-_ _ _ _

The top DIN rail now has the following Standard Bus
modules:
98 99 CF CD CE

- 2 RMC modules consumes 14W

- 1 RMA consumes 4W
- 11 RME modules consumes 77W
As can now be seen, the total power requirement exceeds 91W. In this case, another power
supply would be required. To incorporate another supply in this system simply disconnect
pins 99 and 98 on the remote DIN rail and connect another appropriately sized power supply
to those same pins.

Watlow EZ-ZONE ® RMA Module • 22 • Chapter 2 Install and Wire

 When using a split rail configuration ensure that the interconnections for the Inter-module
Bus and Standard Bus do not exceed 200 feet.
Note:
Module is not provided with a disconnect, use of an external disconnect is required. It
should be located in close proximity to the module and be labeled as the disconnect for
the module.

Note:
Connecting power supplies in parallel is not allowed. When power consumption is greater
than 91 watts use a split rail configuration.

Wiring a Serial EIA-485 Network

Do not route network wires with power wires. Connect network wires in daisy-chain fash-
ion when connecting multiple devices in a network. A termination resistor may be required.
Place a 120 Ω resistor across T+/R+ and T-/R- of the last con-troller on a on a network.
Note:
Termination resistors when used, require a termination resistor at both ends of the net-
work.

 Range
Within this column notice that on occasion there will be numbers found within parenthesis.
This number represents the enumerated value for that particular selection. Range selections
can be made simply by writing the enumerated value of choice using any of the available
communications protocols. As an example, turn to the Setup Page and look at the Backup
Menu. To Save a configuration backup of all connected zones using Modbus simply right the
value of 1646 (save) to Modbus register 1270.
Communication Protocols
All RM modules come with the standard offering of Watlow's Standard Bus protocol used pri-
marily for inter-module communications as well as for configuration using EZ-ZONE Configu-
rator and Composer software (free download from Watlow's web site (http://www.watlow.
com). Along with Standard Bus, the RMH module can also be ordered with Modbus RTU (only
one protocol can be active at any given time). The RMA module has options for several dif-
ferent protocols listed below:
-- Modbus RTU 232/485
-- EtherNet/IP, Modbus TCP
-- DeviceNet
-- Profibus DP
To learn more about any of the available RM modules, click on the link below. Once there
simply type in RM in the Keyword field. http://www.watlow.com/literature/manuals.cfm
Modbus RTU Protocol
All Modbus registers are 16-bits and as displayed in this manual are relative addresses (ac-
tual). Some legacy software packages limit available Modbus registers to 40001 to 49999 (5
digits). Many applications today require access to all available Modbus registers which range
from 400001 to 465535 (6 digits).
Note:
In this User's Guide, all values shown representing Modbus addresses are added to 400,001
or 40,001 to acquire the absolute address.
For parameters listed as float notice that only one (low order) of the two registers is listed,
this is true throughout this document. By default, the low order word contains the two low
bytes of the 32-bit parameter. As an example, look in the RMA Setup Page for the Analog pa-
rameter under the Variable menu. Find the column identified in the header as Modbus Rela-
tive Address, notice that it lists register 1034. Because this parameter is a float it is actually
represented by registers 1034 (low order bytes) and 1035 (high order bytes). The Modbus
specification does not dictate which register should be high or low order so Watlow provides
the user the ability to swap this order (Setup Page, Communications Menu) from the default
low/high to high/low.
It should also be noted that some of the cells in the Modbus column contain wording pertain-
ing to an offset. Several parameters in the RMA contain more than one instance; such as,
Data Log points (200), Gateway Instances (17), etc... The Modbus register shown always rep-
resents instance one. Take for an example the Log Point parameter found in the RMA Setup
Page under the Log Point menu. Instance one for the Source Function is shown as address
1470 and the offset to the next instance is identified as +16. If there was a desire to read or
write to instance 3, simply add 32 to 1470 to find the appropriate address; in this case, Log
Point Source Function 3 address would be identified as 1502.

the Common Industrial Protocol (CIP). Due to the use of CIP as the foundation of either pro-
tocol (DeviceNet or EtherNet/IP), they both use the same addressing scheme and parameter
addresses can be found in the column header identified as CIP. There you will find the Class,
Instance and Attribute in hexadecimal, (decimal in parenthesis) for both protocols.
Note:
The RMA module equipped with EtherNet/IP supports implicit and unconnected explicit mes-
sages.
Data Types Used with CIP
uint = Unsigned 16 bit integer
int = Signed 16-bit
dint = Signed 32-bits, long
real = Float, IEEE 754 32-bit
string = ASCII, 8 bits per character
sint = Signed 8 bits , byte

RMA _ - A [3] _ _ - A A _ _
To learn more about the DeviceNet and EtherNet/IP protocol point your browser to http://
www.odva.org.

Profibus DP
To accommodate for Profibus DP addressing the following menus contain a column identified
as Profibus Index. Data types used in conjunction with Profibus DP can be found in the table
below.

Data Types Used with Profibus DP

word = Unsigned 16 bit
int = Signed 16-bit Integer
dint = Signed 32-bit Integer
real = Float, IEEE 754 32-bit
char = ASCII, 8 bits per character
byte = 8 bits

RMA _ - A [6] _ _ - A A _ _

 Saving and Restoring Settings Using an RUI
Recording setup and operations parameter settings for future reference is very important. If
you unintentionally change these, you will need to program the correct settings back into the
controller to return the equipment to operational condition.
After you program the controller and verify proper operation, use Save Settings As Usr.s
(Setup Page, Global Menu) to save the settings into either of two files in a special section of
memory.
If the settings in the controller are altered and you want to return the controller to the
saved values, use Restore Settings From Usr.r (Setup Page, Global Menu) to recall the previ-
ously saved settings.
Note:
Restoring to factory defaults will overwrite the entirety of the module memory; this would
include any customized assemblies used with any of the available communications proto-
cols.

Note:
Only perform the above procedure when you are sure that all the correct settings are pro-
grammed into the controller. Saving the settings overwrites any previously saved collec-
tion of settings. Be sure to document all the controller settings.

Using Password Security

It is sometimes desirable to apply a higher level of security when using an RUI with any of
the RM modules where a limited number of menus are visible while also not providing access
to others without a security password. Without the appropriate password those menus will
remain inaccessible. If Password Enabled pas.E in the Factory Page under the Lock LoC Menu
is set to on, an overriding Password Security will be in effect. When in effect, the only Pages
that a User without a password has visibility to are defined in the Locked Access Level LoC.L
prompt. On the other hand, a user with a password would have visibility restricted by the
Read Lockout Security rLoC. As an example, with Password Enabled and the Locked Access
Level LoC.L set to 1 and rLoC is set to 3, the available Pages for a user without a password
would be limited to the Home and Factory Pages (locked level 1). If the user password is en-
tered all pages would be accessible with the exception of the Setup Page as defined by level
3 access.
How to Enable Password Security
1. Go to the Factory Page by holding down the Infinity ˆ key and the Advance ‰ key for ap-
proximately six seconds.
2. Again push the Advance ‰ key until the Password Enabled pas.E prompt is visible. Lastly,
push either the up or down key to turn it on.
Once Password Enable is turned on, 4 new prompts will appear:
3. LoC.L - Locked Access Level (1 to 5) corresponding to the lockout table above.
4. roLL - Rolling Password will change the Customer Code every time power is cycled.
5. pas.u, User Password which is needed for a User to acquire access to the control.
6. pas.a, Administrator Password which is needed to acquire administrative access to the
control.
The Administrator can either change the User and or the Administrator password or leave
them in the default state. Once Password Security is enabled they will no longer be visible to
anyone other than the Administrator. As can be seen in the formula that follows, either the

Watlow EZ-ZONE ® RMA Module • 57 • Chapter 6 Features

 User or Administrator will need to know what those passwords are to acquire a higher level
of access to the control. Back out of this menu by pushing the Infinity ˆ key. Once out of the
menu, the Password Security will be enabled.
How to Acquire Access to the Module
To acquire access to any inaccessible Pages or Menus, go to the Factory Page and enter the
Unlock ULoC Menu. Once there follow the steps below:
Note:
The unlock menu will appear only if the Password Enable prompt has been enabled.
1. Acquire either the User Password pas.u or the Administrator Password pas.a.
2. Push the Advance ‰ key one time where the Code CodE prompt will be visible.
Note:
a. If the the Rolling Password is off push the Advance key one more time where the Pass-
word pass prompt will be displayed. Proceed to either step 7a or 8a. Pushing the
Up ¿ or Down ¯ arrow keys enter either the User or Administrator Password. Once en -
tered, push and hold the Infinity ˆ key for two seconds to return to the Home Page.
b. If the Rolling Password roLL was turned on proceed on through steps 3 - 9.
3. Assuming the Code CodE prompt (Public Key) is still visible on the face of the control sim-
ply push the Advance key ‰ to proceed to the Password pass prompt. If not find your way
back to the Factory Page as described above.
4. Execute the calculation defined below (7b or 8b) for either the User or Administrator.
5. Enter the result of the calculation in the upper display by using the Up ¿ and Down ¯ ar-
row keys or use EZ-ZONE Confgurator Software.
6. Exit the Factory Page by pushing and holding the Infinity ˆ key for two seconds.
Formulas used by the User and the Administrator to calculate the Password follows:
Passwords equal:
7. User
a. If Rolling Password roLL is Off, Password pass equals User Password pas.u.
b. If Rolling Password roLL is On, Password pass equals: (pas.u x code) Mod 929 + 70
8. Administrator
a. If Rolling Password roLL is Off, Password pass equals User Password pas.a.
b. If Rolling Password roLL is On, Password pass equals: (pas.a x code) Mod 997 + 1000
Differences Between a User Without Password, User With Password and Administrator
- User without a password is restricted by the Locked Access Level LoC.L.
- A User with a password is restricted by the Read Lockout Security rLoC never having ac-
cess to the Lock Menu LoC.
- An Administrator is restricted according to the Read Lockout Security rLoC however, the
Administrator has access to the Lock Menu where the Read Lockout can be changed.

Real Time Clock (RTC)

The RTC is used with the RMC module equipped with the profiling feature and Data Logging
(date and time stamp). With a little thought the programmer can use the RTC to synchronize
RMC profile engines (using wait-for steps, logic and compare functions)
While executing a profile the application requirements may dictate that if power is lost and
then restored that the profile execution automatically terminate or conversely continue
where it left off based on how long the power was out. Within the Setup Page under the

Watlow EZ-ZONE ® RMA Module • 58 • Chapter 6 Features

 Profile Menu a parameter can be found that addresses this need; it is called the "Power Off
Time" poti. This time is defined in seconds and a RTC is required to use this feature. As an
example, if the Power Off Time were set to 300 and the power is lost while a profile is ex-
ecuting and then restored before 5 minutes expires, the profile would continue where it was
at prior to the loss of power. If the power were to be restored after 300 seconds expires the
profile would be terminated.

Data Logging
The RMA module equipped (RMAX-XXXD-XXXX)and configured for data logging is capable of
recording data points every second to every hour. This setting (Period, pErd) can be found
in the Setup Page under the Data Logging Menu. All recording is stored to an SD card on the
RMA module where all data points must be from RM modules on the same Inter-module Bus
network. The RMA module equipped with this feature is shipped with a 2 GB card. If a user
chose to use one of their own there is no limitation with regards to the size of the SD card
that can be used.
Along with the setting for the frequency of the writing activity there is another setting that
the user will set (Full Action, f.act) that determines how the RMA module will react when
the card becomes full, as the name implies. When free memory is less than 1 MB, the card is
considered to be full. This setting can also be found on the Setup Page under the Data Log-
ging Menu. There are two actions that can be taken when this condition exists:
1. Stop
2. Overwrite - then delete oldest files first until an additional 1.5 MB is available.
The file name and folder structure as it is stored to the SD card is defined in the RMA firm-
ware and can be seen below. When the file number needs to increment, the current file
shall be closed and the new file will be opened. Conditions that can cause the file number to
increment:
• RMA module powers up
• RTC date changes
• File size reaches the maximum size of 1 MB
• Number of lines exceeds maximum number of lines supported by Microsoft Excel
• Defined log points are changed
• USB mounts and dismounts the SD card
All files saved to the SD card are in comma delimited format where they can be easily
opened using any software package capable of
reading *.csv files, such as Microsoft® Excel.
After data logging is complete the SD card can
be read via an SD card reader or from the RMA
module directly. To connect the PC directly to
the RMA module simply connect a mini-USB
cable to the RMA and a type B (for most computers) USB cable to the PC.
Note:
All data logging will discontinue after a USB cable is connected from the PC to the RMA
module.
Once connected to the SD card, drill down to the data files and simply open it up using your
software of choice to see the recorded data. The data below was recorded from an RMC
module (zone 8). The date and time formats can be changed (Setup Menu, RTC Menu) along
with the precision of the data (Setup Page, Log Point Menu).
Watlow EZ-ZONE ® RMA Module • 59 • Chapter 6 Features
 Backup
The RMA module equipped with limited backup capabilities (RMAX-XXXA-XXXX) can backup
no more than 4 RM modules. It will do so from the lowest to highest zone number. Because
this option stores the backup information for these modules in the on-board memory of the
RMA itself, there are some dependencies that must be considered. All four modules will be
backed up if no more than 2 modules has profiling capabilities. If there are more than 2
modules with profiling, the last module will not be backed up. If all 4 have profiling just 2
out of the 4 modules will be backed up. If there is a need to backup all modules the unlim-
ited version must be used. The unlimited version (RMAX-XXX[B,Y,D]-XXXX) stores all backup
information to the SD card for all RM modules on the Standard Bus network from the lowest
to highest zone number.
Note:
While performing a backup if the SD card runs out of memory the backup will occur on
zones up to the last zone that fit on the SD Card. For this reason, it would make sense to
perform a backup of all RM modules prior to data logging.

Note:
Only parameters associated with a prompt are saved and restored, the same set available
through EZ-ZONE Configurator, not User Set 1 or 2.

Note:
Assemblies for any of the RM modules are not backed up.

Restore
If the user sets Restore to Now, all modules that had been previously backed up will be re-
stored from the lowest zone to the highest assuming zone address and the part numbers are
the same.
If the user sets Restore to Change, the RMA will restore all modules with a serial number
change. For this to occur the zone address and part numbers for the swapped out modules
must be identical to those that had been previously backed up.

Watlow EZ-ZONE ® RMA Module • 60 • Chapter 6 Features

 Software Configuration
To enable a user to configure the RM module using a personal computer (PC), Watlow has
provided two different programs free of charge for your use.
• EZ-ZONE Configurator (text based), originally released with the EZ-ZONE family of controls.
• Composer (graphic based), released September 2014.
Note:
RM modules must have firmware revision 9.0 and above to be used with Composer soft-
ware.
Both programs can be acquired directly from the DVD (Controller Support Tools) which
shipped with the controller. Insert the DVD into your DVD drive and select and install the
preferred software. Alternatively, if you are viewing this document electronically and have
a connection to the internet, simply click on the link below and type either Configurator
or Composer into the Keyword field and then click Search to download the software free of
charge. http://www.watlow.com/literature/software.cfm

Using EZ-ZONE® Configurator Software

Installing the Software
To install the software:
1. Double-click the filename " EZCv6.exe.
2. After reading the license agreement click the I accept the terms in the License Agree-
ment radio button and then click on the Next button to proceed.
3. Once the installation is complete, click the Finish button.
Starting EZ-ZONE Configurator software:
1. Double-click the EZ-ZONE Configurator icon on the desktop.
Or
2. On the task bar, click Start and type ez-zone configurator.exe in the search box and then
press Enter.
3. Once the executable is found double-click the file to run.
The first screen that will appear is shown below.

Watlow EZ-ZONE ® RMA Module • 61 • Chapter 6 Features

 If the PC is already physically connected to the RMA module click the next button to go on-
line.
Note:
When establishing communications from PC to the RMA module an interface converter
will be required. The Standard Bus network uses EIA-485 as the interface. Most PCs today
would require a USB to EIA-485 converter. However, some PCs may still be equipped with
EIA-232 ports, therefore an EIA-232 to EIA-485 converter would be required.
As can be seen in the above screen shot the software provides the user with the option of
downloading a previously saved configuration as well as the ability to create a configuration
off-line to download later. The screen shots that follow will take the user on-line.
After clicking the next button above it is necessary to select the communications port on the
PC to use.

The available options allow the user to select "Try them all" or to use a specific known com-
munications port. After installation of your converter if you are not sure which communica-
tions port was allocated select "Try them all" and then click next. The screen to follow shows
that the software is scanning for devices on the network and that progress is being made.

Watlow EZ-ZONE ® RMA Module • 62 • Chapter 6 Features

 When complete the software will display all of the available devices found on the network as
shown below.

In the previous screen shot the RMA is shown highlighted to bring greater clarity to the mod-
ule in focus. Any EZ-ZONE device on the network will appear in this window and would be
available for the purpose of configuration or monitoring. After clicking on the module of
choice simply click the next button once again. The next screen appears below.

Watlow EZ-ZONE ® RMA Module • 63 • Chapter 6 Features

 In the screen shot above notice that the device part number is clearly displayed at the top
of the page (green highlight added for emphasis). When multiple EZ-ZONE devices are on
the network it is important that the part number be noted prior to configuring so as to avoid
making unwanted configuration changes to another control.
Looking closely at the left hand column (Parameter Menus) notice that it displays all of the
available menus and associated parameters within the control. The menu structure as laid
out within this software follows:
- Setup
- Operations
- Factory
Navigating from one menu to the next is easy and clearly visible. Simply slide the scroll bar
up or down to display the menu and parameter of choice. As an alternative, clicking on the
negative symbol next to Setup will collapse the Setup Menu where the Operations Menu will
appear next and perhaps deliver more clarity for the area of focus by not displaying un-
wanted menus and parameters. Once the focus is brought to an individual parameter (single
click of mouse) as is the case for Local Remote Gateway 1 in the left column, all that can
be setup related to that parameter will appear in the center column. The grayed out field in
the center column simply means that those parameters do not apply. In this particular case,
Modbus TCP Enable has been set to No under the Communications Menu, therefore, it is not
possible to define the Modbus Address Offset. To speed up the process of configuration no-
tice that at the bottom of the center column there is an option to copy settings. If Gateway
1, 2 and 3 will be configured the same click on "Copy Settings" where a copy from / to dialog
box will appear allowing for quick duplication of all settings. Notice too, that by clicking on
any of those items in the center column that context sensitive help will appear for that par-
ticular item in the right hand column.
Lastly, when the configuration is complete click the "Finish" button at the bottom right of
the previous screen shot. The screen that follows this action can be seen below.

Although the RMA module now contains the configuration (because the previous discussion
focused on doing the configuration on-line) it is suggested that after the configuration pro-
cess is completed that the user save this file on the PC for future use. If for some reason
someone inadvertently changed a setting without understanding the impact it would be easy
and perhaps faster to download a saved configuration back to the control versus trying to
figure out what was changed. Of course, there is an option to exit without saving a copy to
the local hard drive.

Watlow EZ-ZONE ® RMA Module • 64 • Chapter 6 Features

 After selecting Save above click the "Finish" button once again. The screen below will than
appear.

When saving the configuration note the location where the file will be placed (Saved in) and
enter the file name (File name) as well. The default path for saved files follows:
\Program Files\Watlow\EZ-ZONE CONFIGURATOR\Saved Configurations
The user can save the file to any folder of choice.

Watlow EZ-ZONE ® RMA Module • 65 • Chapter 6 Features

 Function Block Descriptions
Each of the next several pages graphically shows each of the RMA function blocks. Note that
as you view each you will find text that is black and text that appears gray. The gray text
represents inputs that are not currently available based on the functions defined use (red
text). For instance, when the defined use of the Ethernet IP Address Mode is set to DHCP
(where a DHCP host supplies the IP address) all fields for the IP address will appear gray.

Backup / Restore Function

Restores configuration settings into changed modules based on serial number change. Will
not restore modules having different hardware configurations. Ensure Standard Bus address
is set to match replaced module before restoring settings.
There is one Backup Status instance in the Operations Page for each module on the standard
bus network.

 Gateway Function
There is one menu instance for each zone (each standard bus address, 1 to 17). Use these
settings to configure each gateway to provide data from the devices on the Standard Bus net-
work to the fieldbus network (Modbus RTU, Modbus TCP, DeviceNet, EtherNet/IP or Profibus
DP).
• Ensure that only those gateways that have a corresponding module are enabled. If data is
not required from a particular module, field bus addressing space may be conserved by leav-
ing that gateway disabled.
• Each module must have a unique Standard Bus address. Use the button on the front of each
module to set a unique address. We suggest that the RMA remain at address ‘J’ or 17. If
changed, ensure it is the highest address in the system.
Note:
If it is desired to communicate to the internal registers of the RMA, enable Local Remote
Gateway with same Standard Bus address as the RMA module.

 Gateway (cont.)
Modbus® RTU or TCP
There is one menu instance for each zone (each Standard Bus address, 1 to 17). Use these
settings to configure the gateway to provide data from the devices on the Standard Bus net-
work to the Modbus RTU network.
• Use Device Enabled to enable the gateway function for the device.
• Device Status indicates if the device is currently active on the Standard Bus network.
• Use Modbus Address Offset to stagger the Modbus registers of the EZ-ZONE controller's pa-
rameters that are to be accessed through the gateway via Modbus communications. The
purpose of the offset is to divide the linear address space for Modbus which ranges from 0
to 65,535 into groups allocated to each module. The range for each module must be large
enough to reach the highest register required. As an example, Gateway 1 has an offset of
0 and Gateway 2 has an offset of 10,000. Registers 0 to 9,999 can be accessed in module 1.
Reading register 10,000 will retrieve register 0 of module 2. The Modbus Address Offset is
added to the Modbus address of each parameter in the EZ-ZONE controller at this Standard
Bus address. Use a large enough value to shift this controller's parameters above the ones
you need to access in devices with lower zone numbers on the Standard Bus network.

CIP (EtherNet/IP and DeviceNet)
There is one menu instance for each zone (each Standard Bus address, 1 to 17). Use these
settings to configure the gateway to provide data from the devices on the Standard Bus net-
work to the fieldbus network (DeviceNet or EtherNet/IP).
• Use Device Enabled to enable the gateway function for the device.
• Device Status indicates if the device is currently active on the Standard Bus network.
• CIP Instance Offset is used for explicit messages only. Use CIP Instance Offset to stagger
the CIP instances of the EZ-ZONE controller's parameters that are to be accessed through
the gateway via DeviceNet or EtherNet/IP. The CIP Instance Offset is added to the CIP In-
stance of each parameter in the EZ-ZONE controller at this Standard Bus address. Use a large
enough value to shift this controller's parameters above the ones you need to access in de-
vices with lower zone numbers on the Standard Bus network.
• CIP Implicit Assembly Input/Output Member Quantity defines the size for sending/receiving
data implicitly to/from a PLC. The RMs output is the PLC’s input. The RM’s input is the PLC’s
output. There will be one additional member sent called Device Status in addition to the
quantity specified by the RM Output Member Quantity. There is only one 32-bit Device Sta-
tus word sent per system (not one for each Local Remote Gateway).

 Gateway (cont.)
Profibus
There is one menu instance for each zone (each Standard Bus address, 1 to 17). Use these
settings to configure the gateway to provide data from the devices on the Standard Bus net-
work to the Profibus DP network.
• Use Device Enabled to enable the gateway function for the device.
• Device Status indicates if the device is currently active on the Standard Bus network.
• Use Slot Offset to stagger the addresses of parameters in EZ-ZONE controllers accessed
through the gateway via acyclic (DP-V1) Profibus communications. A Profibus master accesses
parameters in an EZ-ZONE controller using an address consisting of two parts: Slot and Index.
The Index for each accessible parameter is listed in the EZ-ZONE controller's User's Manual.
The Slot is determined by the Slot Offset and the Instance of the parameter to be read or
written.
For example, The Index for Alarm 1 High Set Point found in the user's guide is 19. To access
this parameter in a controller with its Slot Offset set to 10, the address is Slot 10 and Index
19. To address the next alarm's high set point, Alarm 2 High Set Point in the same controller,
use the next Slot, 11 and the same Index, 19. The Slot Offset for the first controller is typi-
cally set to zero (0). The Slot Offset set for each subsequent controller determines the num-
ber of parameter instances that can be accessed in the previous controllers configured in the
gateway. Use a large enough offset to allow unique slot numbers for all the instances of the
parameters you want to access in the controllers with lower zone numbers on the Standard
Bus network.

 7 Chapter 7: RMA Communications
EZ-ZONE RMA & Communications
With the introduction of the first Programmable Logic Controllers (PLC's) in the early to mid
1970's it quickly became apparent that there was a need to communicate between one PLC
and another, and then on a wider scale, between PLC's and other computers within the com-
pany infrastructure. Some of those needs involved applications with interlinking processes,
such as batch processes or assembly lines utilizing multiple controls that required better
synchronization and control.
Over time, the scope of the requirements for industrial communications broadened and be-
came better defined, with specific needs being addressed. Those requirements and specifica-
tions centered on collecting data, configuring controls, and controlling a process.
Protocols
The Protocol describes how to exchange data. Due to the volume of traffic (limited band-
width) and sensitivity to disturbances on the network the protocol will define the number of
bits in a packet of information, the speed of the data transfer, whether or not error checking
is done, etc... There are a number of different data communications protocols in use today.
The EZ-ZONE RMA module can be optionally equipped with the following protocols:
- Modbus® RTU & TCP
- Profibus® DP
- EtherNet/IP™
- DeviceNet™
Each of these protocols are heavily in use today within a wide array of industrial applica-
tions.
Modbus
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
reliable in exchanging information, a highly desirable feature for industrial data communi-
cations. 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 RM module User's Guide has a
comprehensive listing of these registers found in the Operations, Setup, Profiling, and Fac-
tory Pages.
Many parameter values within the various RM modules are four bytes in length and require
two Modbus registers. By default, the low order word contains the two lower bytes of the 32
bit parameter and the high register number contains the two higher bytes. If it makes your
programming easier you may reverse this Modbus default when using RM modules where the
low register number contains the two higher bytes and the high register number contains the
two lower bytes. This setting can be modified in the RM Access Setup pages under the Com-
munications CoЛЏ Menu.
If it is desired to acquire more information on Modbus RTU or Modbus TCP direct your brows-
er to: http://www.modbus.org.
Watlow EZ-ZONE ® RMA Module • 79 • Chapter 7 RMA Communications
 User Programmable Memory Blocks
All RM modules equipped with the Modbus protocol features a block of 80 contiguous Mod-
bus registers that can be configured by the user to reflect up to 40 members (parameters)
of their choice. This assembly allows for direct read/write (depending on actual parameter)
access in one contiguous block.
To acquire a better understanding of the tables found in the back of this guide please read
through the text below which defines the column headers used. (See Appendix: Modbus Pro-
grammable Memory Blocks)
Assembly Definition Addresses
Fixed addresses used to define the parameter that will be stored in the "Assembly Working
Addresses"; may also be referred to as a pointer. The value stored in these addresses will
reflect (point to) the Modbus address of a parameter within an RM module.
Assembly Working Addresses
Fixed addresses directly related to their associated "Assembly Definition Addresses" (e.g.,
Working Addresses 200 & 201 will assume the parameter pointed to by definition addresses
40 & 41). Take a look at the section entitled "Modbus Default Assembly Structure 40-119"
found in the Appendix. The RMC assembly can be seen where the first member is identified as
"Control Loop Set Point 1". This is a writable parameter, therefore, within the user program
when writing a new value to Modbus registers 200 and 201 the RMC loop 1 Closed Loop Set
Point will change accordingly. So, when the Modbus address of a target parameter is stored
in an "Assembly Definition Address" its corresponding working address will return that param-
eter’s actual value. If it’s a writable parameter, as in the case described above, writing to its
working registers will change the parameters actual value.

Using Modbus RTU

Default RMA Communication Parameters (Modbus RTU)
If your model number has a two in the identified placeholder (RMA x - x [2] x x - x x x x) then
these defaults apply.
Address (Ad.ЛЏ) = 1
Baud Rate ( bAUd) = 9600
Parity (PAr) = nonE
Word Order ЛЏ.hL) = Lohi
Modbus Units (C_f) = f
Non-volatile Save (nU.s) = yEs
To Change Communications Default Settings Using an RUI

8. Push the Infinity Key ˆ three times or push it and hold for approximately 3 seconds to
navigate back to the Home Page.
Communications To/From a Master:
After configuring the gateway, in order to read or write the expected parameter from the ex-
pected module the Modbus Offset prompt ЛЏ.of is most significant. This parameter provides
an offset for the purpose of module selection while at the same time providing the ability to
read and or write to any given Modbus register.
As an example, lets assume the offsets are as shown in the graphic on the previous page
(RMA with Modbus RTU Gateway) and the Master wants to read instance one Set Point from
both RMC modules at address 1 and 4. Open up the RMC User's Guide, turn to the Opera-
tions Page and look in the Loop Menu for Set Point. To read instance one Set Point from RMC
module address 1, the appropriate Map 1 address would be: 2500 + Modbus offset (0) = 2500.
Notice that there is no offset applied in this example. To read the Set Point from the RMC
module address 4 the address would now be: 2500 + Modbus offset (30000) = 32500.
As can be seen in this example, the Modbus Offset defines the module (in this case, RM 4)
where the specific Modbus address for the parameter in question does not change. The values
given for the Modbus Offset ЛЏ.of prompt also determine the available Modbus addresses
for each module. Looking at the graphic on the previous page, the following Modbus address-
es would be available for each module:
RM 1, 1 - 10,000
RM 2, 10,001 - 20,000
RM 3, 20,001 - 30,000
RM 4, 30,001 - 65,535
Note:
The Modbus Offset ЛЏ.oF as modified through the RUI cannot exceed 9999. Therefore,
if it is desired to utilize a Modbus offset as shown in the previous graphic (above 9999) it
must be entered using EZ-ZONE Configurator software. Simply click on the link below and

Note:
If it is desired to access Modbus addresses for the RMA module ensure that the RMA gate-
way (Standard Bus address) is enabled. An offset may be required if MB registers need to
be accessed in other modulesother modules and has an offset associated with it. In the
example that follows the RMA was given a Modbus Offset of 20,000.

Watlow EZ-ZONE ® RMA Module • 86 • Chapter 7 RMA Communications

 As another example, on this same network resides an RMC module with an offset of 20,001.
As the graphic below shows the Set Point at address 25001 is being read from the RMC mod-
ule ans is displayed in decimal as 75.

Lastly, the example below shows how to modify the Modbus User Programmable Memory
Blocks. As noted earlier, these blocks of memory are also referred to as an assembly. In this
example, the assembly to be modified will be within a RMC module with an offset of 0. Re-
member, if an offset is used simply add it to the Modbus address.
When a controller is delivered from the factory the first 20 members of the 40 available are
pre-configured for the RMC module, referred to as the default state. As can be seen in the
default Modbus assembly configuration graphic found in the Appendix of this user's guide the
first member is configured as the Loop 1 Set Point. In this example, the first two Definition
Addresses (40 and 41), or pointers will be overwritten to point to the Limit 4, High Set Point.
To do this follow the steps below.
Changing and Verifying the MB Assembly:
1. Find the desired parameter and MB register in the appropriate user's guide. In this case,
the MB register that is listed for the first instance of the Limit is shown as 726. Keep in
mind that it is Limit 4 not 1 that will be written to the first assembly member. This infor-
mation is found in the Setup Page, Limit menu in the RMC User's Guide.
2. Add the Map 1 offset (30) to the MB register listed for the appropriate instance. In this
case, the actual address for Limit 4
High Set Point would be: 726 + 90 =
816.
3. In the graphic to the right notice
the value written (yellow highlight)
to register 40 (pointer) is 816. Also
notice that when register 200 and
201 are read back we see a value
400 representing the Limit 4 High
Set Point. Similar steps could be
used to modify all assembly mem-
bers.
Note:
If the RM module is ever brought back to the factory defaults, the assemblies will be over-
written.

 Common Industrial Protocol (CIP)
Introduction to CIP
With the introduction of CIP a user can now collect data, configure a device and control in-
dustrial devices. CIP is an open protocol at the application layer fully managed by the Open
DeviceNet Vendors Association (ODVA, http://www.odva.org). Being that this is an open pro-
tocol there are many independent vendors offering a wide array of devices to the end user.
CIP provides the ability to communicate utilizing both implicit messaging (real-time I/O mes-
saging), and explicit messaging (information/configuration messaging). For implicit commu-
nications using a PLC simply configure the module (RMA) assembly size into the I/O structure
of the PLC (See: CIP Implicit Assemblies). The assembly structure can also be changed by the
user.
Explicit communications requires the use of specific addressing information. DeviceNet re-
quires that the node address be specified where EtherNet/IP requires just the Class, Instance
and Attribute.
• Node address or MAC ID (0 - 63, DeviceNet only)
• Class ID (1 to 255)
• Instance ID (0 to 255)
• Attribute ID (1 to 255)
EtherNet/IP and DeviceNet are both based on CIP. EtherNet/IP (Industrial Protocol) is a
network communication standard capable of handling large amounts of data at speeds of 10
Mbps or 100 Mbps, and at up to 1,500 bytes per packet. It makes use of standard off-the-
shelf Ethernet chip sets and the currently installed physical media (hardware connections).
DeviceNet was the first field bus offering of the ODVA group and has been around for many
years. DeviceNet can communicate at 125, 250 and 500 kilobytes per second with a maxi-
mum limitation of 64 nodes (0 to 63) on the network. The RMA module equipped with Ether-
net and DeviceNet hardware supports implicit and unconnected explicit messages. To enable
Ethernet communications with legacy Allen-Bradley PLCs the Ethernet card also supports the
PCCC protocol.

 CIP Implicit Assemblies
Communications using CIP (EtherNet/IP and DeviceNet) can be accomplished with any RM
module using the RMA. As was already mentioned, reading or writing when using CIP can be
accomplished via explicit and or implicit communications. Explicit communications is usually
executed via a message instruction within the PLC but there are other ways to do this as well
outside of the focus of this document.
Implicit communications is also commonly referred to as polled communications. When using
implicit communications there is an I/O assembly that would be read or written to. The de-
fault assemblies are embedded into the firmware of the specific module in use and they can
be different from module to module. Watlow refers to these assemblies as the T to O (Target
to Originator) and the O to T (Originator to Target) assemblies where the Target is always
the EZ-ZONE controller and the Originator is the PLC or master on the network. For each RM
module, the O to T assembly is made up of 40 (32-bit) members where the T to O consists of
41 (32-bit) members. All assembly members are user configurable with the exception of the
first T to O member. The first member of the T to O assembly is called the Device Status, it
is unique to the RMA and cannot be changed. Bits 16 - 31 of this 32-bit word represents the
communications status of the RM modules (zones) on the Standard Bus side of the RMA when
enabled. Once a zone is enabled, valid communications will be represented with the bit set
to a "1", if set to "0", the RMA is not communicating with the zone. Bit 16 represents Zone 1
where bit 31 represents Zone 16. The 40 members that follow Device Status are user configu-
rable. The Appendix of this User's Guide contains the assemblies for each of the RM modules
(See Appendix: CIP Implicit Assembly Structure by product).
Note:
EtherNet/IP allows for a maximum assembly size of 100 I/O members where DeviceNet al-
lows for a maximum of 200 I/O members.

Compact Implicit Assembly Class

Along with the standard implicit assembly where each module parameter (member) occupies
one 32-bit assembly member there is also a Compact Class of the assembly. The need for the
Compact Class of assembly members became apparent as the high density RM modules (up to
16 control loops) were being developed. The Compact Class allows for better utilization of
each bit within an assembly member by compacting parameters within one 32-bit assembly
member. As an example, if a standard assembly member were configured as a Variable just
7 bits out of the 32 will be used to write an off (62) or on (63) status to the module. With
the Variable Compact Class in use, 16 Variables can be placed in one 32-bit assembly mem-
ber using just 2 bits for each (00 = off, 01 = on). There is a variety of predefined Compact
Class members that can be used (See Appendix: CIP Compact Class Assemblies) to modify the
default implicit assemblies.

Modifying Implicit Assembly Members

There are a couple of ways to modify the assemblies; the easiest way would be to download
a utility program offered by Watlow free of charge and the other way would be to write
explicit messages from the Master to the RM modules. For examples using explicit messages
click the following link http://www.watlow.com/literature/whitepapers.cfm. Once there
type "gateway" into the Keyword field and click Search.
The program mentioned above is free of charge and serves the user well to get up and run-
ning quickly. It can be found and downloaded two ways:

Watlow EZ-ZONE ® RMA Module • 89 • Chapter 7 RMA Communications

 Locate and Download the Implicit Assembly Program:
1. Click on the following link: http://www.watlow.com/literature/software.cfm.
- Type "implicit message" in the Keyword field and click Search
- Click on the file identified as " EZ-ZONE Implicit Message Assembly Programming Ap-
plication" and save the file to your local storage device.
- Extract all of the files.
Or
2. Find and insert the Watlow Support Tools DVD into a DVD drive.
- Once opened, right-click on Utility Tools
- Mouse over "EZ-ZONE" and click on EZ-ZONE_Assembly_Programmer to open up and run
the program
In the example below a RMC module will be used and the first implicit assembly member will
be modified from the loop 1 Set Point to loop 1 Control Mode.
Writing a New Implicit Assembly Member:
1. Open the RMC user's guide and locate the parameter identified as Control loop 1 - Control
Mode. This can be found on the Operations Page under the Loop menu.
2. Identify the column labeled as Parameter ID and note the ID for the desired parameter. In
this case the parameter ID 8001.
3. Ensure that a PC communi-
cations port is connected to
Standard Bus while making
note of the comm port in
use.
4. Locate the unzipped files
from step 4 above and
double-click the file named
EZ-ZONE_Assembly_Pro-
grammer.exe.
5. Select the comm port iden-
tified in step 3 above and
click the Init button (red
box).
6. Enter the RM zone address
that will be modified (blue
box).
7. For Assembly 1 (O to T)
enter 8001 in the Parameter
Id column and 1 (Loop 1) in
the Instance column.
8. Click on the Write button to send to the controller.
9. To the right of the column identified as "Actual Value" click the Read button to validate
that the operation was completed successfully. According to the user's guide 62 indicates
that the controller is off.
If need be, these steps can be duplicated to modify and read all 40 members of both the
input and output assemblies for any RM module.

Watlow EZ-ZONE ® RMA Module • 90 • Chapter 7 RMA Communications

 Note:
Any changes made to the assemblies will be overwritten if the RM module is ever brought
back to factory defaults.

Using EtherNet/IP™
Communications To/From Third Party Device:
When using the EtherNet/IP protocol, there are two methods used in communicating, implic-
itly (See: CIP Implicit Assemblies) and explicitly. Once the gateway instance is enabled there
are two prompts that relate directly to these forms of communication.
Reference the graphic above (RMA with EtherNet/IP Gateway).
ost CIP Offset, used exclusively with explicit messages where this prompt defines the pa-
rameter instance as well as the module on the network. The CIP offset is unique to
each gateway instance (RM module) and should not overlap from one gateway instance
to another.
Application Note:
Assume that in the graphic above that there are 4 RMC modules on the network with each
having 4 instances of an Analog Input. If it is desired to access all of the Analog Inputs
from each module the CIP offset must, at a minimum, have an offset of 4 between each
module (gateway instance). If the offset for each module is set as shown on the follow-
ing page, the 4th instance would not be available. As another example, looking at the
RMC User's Guide in the Setup Page under the Variable Menu, it shows that there are 16
instances available. If all 16 for each module are to be made available to the Master (OIT,
PC, PLC) then the offsets should at a minimum be set as shown below: RM1 = 0, RM2 = 17,
RM3 = 33 and RM4 = 50.
Using the RMC User's Guide look at the Operations Page and then the Analog Input Menu.
There you will find the class, instance and attribute of the first instance of the Analog Input
Value for RM 2 to be the following:
Class = 104 or (0x68)
Instance = 6
Attribute = 1
This information would be needed to execute an explicit message to read this parameter.
Notice that the instance above is identified as 6 and not 1 as listed in the RMC documenta-
tion. The CIP offset is always added to the documented instance. Using the graphic above
the offset entries are listed below.
1. RUI prompt entry for gateway instance 1 (RM 1) follows: oSt = 0
2. RUI prompt entry for gateway instance 2 (RM 2) follows: oSt = 5
3. RUI prompt entry for gateway instance 3 (RM 3) follows: oSt = 10
4. RUI prompt entry for gateway instance 4 (RM 4) follows: oSt = 15
Likewise, to read the Analog Input Value instance 2 of RM 4 the following information would
need to be entered in the message instruction:
Class = 104 or (0x68)
Instance = 17 or (0x0E)
Attribute = 1
ao.nb CIP Implicit Output (Produced, input to Master) Assembly Size, used exclusively when
communicating implicitly. For any given RMA gateway instance (1 - 17), the output as-
sembly size will never be greater than 40, 32 bit members. The user entry ranges from
0 to 40.
Watlow EZ-ZONE ® RMA Module • 91 • Chapter 7 RMA Communications
 ai.nb CIP Implicit Input (Consumed, output from Master) Assembly Size, used exclusively when
communicating implicitly. For any given RMA gateway instance (1 - 17), the input as-
sembly size will never be greater than 40, 32 bit members. The user entry ranges from
0 to 40.
Note:
When configuring the RMA assemblies for each gateway instance it is important to note
that the maximum number of implicit input/output members using EtherNet/IP cannot ex-
ceed 100. A network could have up to 5 EZ-ZONE controllers with 20 members each maxi-
mum or the 100 members can be divided any way the user would like as long as 40 I/O
members per module are not exceeded.
Using the graphic above as an example, if:
gtФІ instance 1 has ai.nb and ao.nb set to 5
gtФІ instance 2 has ai.nb and ao.nb set to 5
gtФІ instance 3 has ai.nb and ao.nb set to 5
gtФІ instance 4 has ai.nb and ao.nb set to 5
Each of the four RM modules will contain the first 5 members of the I/O assembly and this
information would then be passed implicitly to/from the Master on the EtherNet/IP network.
Note:
In the graphic above identified as "RMA with EtherNet/IP Gateway" there are several
prompts omitted for the sake of saving some space. When the Ethernet addressing mode
is set to Fixed the user will find several more prompts that will follow the prompts shown
for "Ethernet Addressing Mode" related to specifying the actual IP ip.f1 - ip.f4, subnet
ip.s1 - ip.s4 and the gateway ip.g1 - ip.g4 (external gateway) addresses. If set to re-
ceive an IP address from a host dhCp computer, the prompts shown are accurate.
Note:
When changing the RMA IP address, power must be cycled for the new address to take af-
fect.

Ethernet Indicator LEDs

The RMA has four indicator LED's on the top of the module for Ethernet, two of which are not
used for Modbus TCP. The Module Status and Network Status LED’s apply only when EtherNet/
IP is enabled. The characteristics of the Activity and Link indicator LED’s are defined in the
Ethernet specification.
This is a view of the RMA module looking down into the top where
the arrow is pointing towards the front of the module.

Using DeviceNet™
Communications To/From Third Party Device:
Like EtherNet/IP when using the DeviceNet™ protocol, there are two methods used in com-
municating, implicitly (See: CIP Implicit Assemblies) and explicitly. Because DeviceNet and
Ethernet/IP both use CIP, the communications examples discussed above apply here as well.
To acquire a better understanding of DeviceNet communications substitute DeviceNet for
EtherNet/IP and review the section entitled "Using EtherNet/IP, Communications To/From a
Third Party Device".

DeviceNet Indicator LED's

The RMA has four indicator LEDs on the top of the module, two of which (rear two) are used
for DeviceNet (Module Status and Network Status). The characteristics of these two LEDs is
established by the Open DeviceNet Vendors Association (ODVA, http://www.odva.org)

Setting DeviceNet Communication Parameters from the RUI Front Panel
Valid DeviceNet node addresses range from 0 - 63 and there are three available baud rates
(network speed) for the user to choose from: 125Kb, 250Kb, or 500Kb. The EZ-ZONE RMA fac-
tory defaults are as follows: Node address = 63, Baud rate = 125Kb
To change the node address, go to the RMA "Setup Page" following the steps below:
1. Push and hold the up and down arrow keys on the front of the RUI for six seconds to go
the Setup Menu.
2. If not already visible push the up or down arrow key until CoЛЏ (Communications Menu)
appears in upper display and SEt in the lower display.
3. Push the green Advance Key ‰ to enter the Communications Menu where the lower display
shows Ad.d and the top display shows the current DeviceNet node address.
4. Push the up or down arrow to change the DeviceNet node address.
5. Push the green Advance Key ‰ once to change the baud rate where the lower display
shows baud and the top display shows the current DeviceNet baud rate.
6. Push the up or down arrow to change to the desired baud rate (125Kb, 250Kb, or 500Kb)
7. Push the green Advance Key ‰ once to enable/disable the DeviceNet quick connect fea-
ture. The lower display shows fC.E and the top display will show no or yEs based on the
current setting.
8. Push the up or down arrow key to enable or disable the quick connect feature.
9. Push the green Advance key ‰ once to change the temperature units passed over De-
viceNet where the lower display shows C_F and the top display will show f or C based
on the current setting.
10. Push the up or down arrow to change to the temperature units.

There are three prompts delivered to the user from the RUI when attached to the RMA that
are related to DeviceNet. Two of which are defined above, bAud (network baud rate or
speed) and Ad.d (network node address). There is one other which is identified and explained
below: FC.E (Quick Connect)
The Quick Connect feature is an option enabled on a node-by-node basis. When enabled, a
device transitions to the on-line state concurrently with sending the first Duplicate MACID re-
quest message. The device is still required to execute the network State Tranisition Diagram
(STD, used to describe object behavior), including going offline anytime a Duplicate MACID
response message is received.
Note:
Although this feature allows a device to begin communicating on the network faster, it is
at the expense of a delay in the duplicate node detection algorithm. It is left up to the
user to guarantee that no nodes exist with the same MAC ID and that no more than one
client device is configured to access the same device using the predefined Master/Slave
connection set. Bus errors may occur if either of these conditions exists. This feature is
enabled within a device through a non-volatile attribute in the DeviceNet object. A device
shall have this feature disabled (attribute set to ‘0’) as the factory default.
Once the above parameters have been changed cycle power on the DeviceNet network for
the new parameters to take affect.

Profibus DP
Introduction to Profibus DP
Profibus was created by the German government in the late 80's due to industrial automa-
tion demand. Profibus DP (Decentralized Periphery) is a serial communications fieldbus using
EIA-485 as the physical layer and is in accordance with the European Electrical Specification
EN50170.
Profibus DP uses a master slave network configuration where RM modules equipped with this
protocol serve as the slave. The RMA equipped with the Profibus DP protocol supports cyclic

Watlow EZ-ZONE ® RMA Module • 96 • Chapter 7 RMA Communications

 (DP-V0) and acyclic (DP-V1) communications. For your reference, cyclic communications
implies that a set of defined parameters (user configured as it relates to the RMA) are pe-
riodically read and or written. The frequency or period of the read/write operations is de-
termined (setup) via the master on the network. You can configure the cyclic parameter set
by installing the software (Profibus GSD Editor for EZ-ZONE Products) which can be found on
the CD that came with the product (Controller Support Tools) or by clicking on the link below
where it can be downloaded free of charge, point your browser to: http://www.watlow.com/
literature/pti_search.cfm?dltype=4
Once the GSD (Generic Station Description) file is created, simply upload it to the master
device.
Acyclic communications will read and or write data on demand and is based on the Slot Off-
set (as defined in the RMA configuration) and the specific parameter index (as can be found
in the menus of the modules User's Guide). Most of the discussion that follows is related to
acyclic communications.
As with all of the other available protocols, prior to establishing communications between
master and the slave the gateway instance must first be enabled du.En. Once enabled, the
user must define the Slot Offsets for each enabled EZ-ZONE controller.
Use the graphic below (RUI being used as a Profibus DP Gateway) in reference to the descrip-
tions that follow below.
s.of Slot Offsets are used exclusively with acyclic (DP-V1) communications and define the
individual EZ-ZONE controller on the network as well as the instance of the parameter
to be read or written to. The offset defaults are as shown in the graphic in incre-
ments of 20, however, they can be changed based on user needs.
As an example, when programming the master device ensure that the Slot Offset and the
Profibus Index (found in each product User's Guide in the various menus) are defined. To read
the first instance of the Analog Input Value in RM 2 use the following information when pro-
gramming the Master: RM 1

other RM module assemblies are undefined as delivered from the factory; if the undefined
members are to be used, they must be configured by the user.

 As can be seen on the previous page, the RMC module is the only RM module that defaults
to a populated assembly structure. If it is desired to use the implicit assembly for any of the
other RM modules the assembly structure must be built by the user. Their are many software
tools available to modify the assembly structure, one of which is described in this user's
guide. What can be found in this document is the process to build the assembly structure. If
viewing this document electronically simply click on the link below to read the section en-
titled " Modifying Implicit Assembly Members". Otherwise, turn back to the table of contents
to find the above named section.

Compact Class Assembly Structure

On the next six pages, the 17 available members of the Compact
Class are displayed. As an orientation to the format as displayed in
this document, notice that each member begins with header identi-
fied as "Assembly" and below the header you will see the member
number along with parameter information contained within. While
looking at these illustrations keep in mind that each member is actually 32-bits in length.
To better illustrate this information in this document, the following 6 pages present these
members divided in half where the letter "A" in the page header and assembly number rep-
resents the most significant 16-bits where the letter "B" in the title and assembly number
represents the least significant 16-bits of each member. In the event that these pages are
printed out and then mixed up, simply match up the page headers placing them side by side.
As an example, Compact Class 1 A through 7 A should be paired with Class 1 B through 7 B,
left to right.
For further explanation as to what the Compact Class assembly is, navigate to the RMA Com-
munications Chapter and then to the section entitled "Compact Implicit Assembly Class"
