1.4 Fieldbus Overview

What is Fieldbus Fieldbus is an all digital, serial, two-way communication system which
interconnects industrial "field" equipment such as sensors, actuators, and
controllers. Fieldbus is a Local Area Network (LAN) for field
instruments with built-in capability to distribute the control application
across the network. See Figure 4.

Interface)

FF FF Device Device

24097

Open System Design The Fieldbus Foundation has defined standards to which field devices
and operator/control stations communicate with one another. The
communications protocol is built as an "open system" to allow all field
devices and control equipment which are built to fieldbus standards to be
integrated into a control system, regardless of the device manufacturer.
This interoperability of devices using fieldbus technology is to become
the industry standard for automation and distributed control systems.

1.4 Fieldbus Overview Continued

Hardware The physical architecture of fieldbus allows installation of fieldbus

Architecture devices using a twisted-pair cable. Often, existing wiring from analog
devices can be used to wire up digital fieldbus devices. Multiple field
devices can be connected on one cable (a multi-drop link), rather than
conventional point-to-point wiring used for analog devices. For more
details on wiring fieldbus networks, see Section 5.4.

Software Architecture Fieldbus software architecture provides for more control functions to be
available in the microprocessor-based field device. Since fieldbus is a
digital communication system, more data is available to operators for
process monitoring, trend analysis, report generation, and trouble
analysis. Device software changes can be downloaded to field devices
remotely from the operator station (or PC) in the control room.

Application An application is software that contains function block data and operating
parameters (objects) which help define the operation of a device such as,
sensor data acquisition or control algorithm processing. Some devices
may contain more than one application.

Function Blocks Usually, a device has a set of functions it can perform. These functions
are represented as function blocks within the device. See Figure 5.
Function blocks are software that provide a general structure for
specifying different device functions. Each function block is capable of
performing a control function or algorithm. Device functions may
include analog input, analog output, and Proportional Integral Derivative
(PID) control. These blocks can be connected together to build a process
loop. The action of these blocks can be changed by adjusting the block's
configuration and operating parameters.

5.3 Piping ST 3000 Transmitter

Summary The actual piping arrangement will vary depending upon the process
measurement requirements and the transmitter model. Except for
flanged and remote diaphragm seal connections, process connections are
made to ¼ inch or ½ inch NPT female connections in the process head
of the transmitter’s meter body. For example, a differential pressure
transmitter comes with double-ended process heads with ¼ inch NPT
connections but they can be modified to accept ½ inch NPT through
optional flange adapters. Some gauge pressure transmitters have a ½
inch NPT connection which mounts directly to a process pipe.

The most common type of pipe used is ½ inch schedule 80 steel pipe.
Many piping arrangements use a three-valve manifold to connect the
process piping to the transmitter. A manifold makes it easy to install
and remove a transmitter without interrupting the process. It also
accommodates the installation of blow-down valves to clear debris from
pressure lines to the transmitter.

Figure 18 shows a diagram of a typical piping arrangement using a

three-valve manifold and blow-down lines for a differential pressure
transmitter being used to measure flow.

process steam. The siphon
retains water as a “fill fluid.”

ATTENTION For liquid or steam, the piping should slope a minimum of 25.4 mm
(1 inch) per 305 mm (1 foot). Slope the piping down towards the
transmitter if the transmitter is below the process connection so the
bubbles may rise back into the piping through the liquid. If the
transmitter is located above the process connection, the piping should
rise vertically above the transmitter; then slope down towards the
flowline with a vent valve at the high point. For gas measurement, use a
condensate leg and drain at the low point (freeze protection may be
required here).
See Appendix C for some suggested freeze protection solutions.

5.3 Piping ST 3000 Transmitter Continued

ATTENTION Care must be taken when installing transmitters on hot processes. The
operating temperature limits for the device (as outlined in Table 4) must
not be exceeded. Impulse piping may be used to reduce the temperature
of the process that comes into contact with the transmitter meter body.
As a general rule there is a 56 degree C drop (100 degree F) in the
temperature of the process for every foot of ½-inch uninsulated piping.

5.4 Wiring ST 3000 FF Transmitter

Wiring the The ST 3000 FF transmitter is designed to operate in a two-wire fieldbus

Transmitter to a network. Although wiring the transmitter to a fieldbus network is a
Fieldbus Network
simple procedure, there are a number of rules that should be followed
when constructing and wiring a network. This section provides general
guidelines that should be considered when wiring the transmitter to a
fieldbus network segment. A procedure is given in this section for
properly wiring the transmitter.

For Detailed Fieldbus Refer to Fieldbus Foundation document AG-140, Wiring and
Wiring Information Installation 31.25 kbit/s, Voltage Mode, Wire Medium Application
Guide for complete information on wiring fieldbus devices and building
fieldbus networks.

Fieldbus Device The ST 3000 FF is identified as either of the following Fieldbus Device
Profile Type Profile Types in Table 15, (as per Fieldbus document #FF-816):
Table 15 Foundation Fieldbus Profile Types
Device Profile
Type: Characteristic
111 113

X X Uses standard-power signaling to communicate on a

fieldbus network.

X X Is a bus-powered device.
(The transmitter does not have an internal power supply and
so it receives its dc power from the fieldbus.)

X Is acceptable for intrinsically safe (I.S.) applications

X Is acceptable for non I.S. applications

Fieldbus Network There are a number of basic components used in constructing a fieldbus
Components network. These items can include:
· Fieldbus cable - Consists of a shielded, twisted pair made to fieldbus
specifications. (Although existing two-wire cable can be used in
some installations, fieldbus cable is recommended for new
installations.)
· Fieldbus power supply.
· Power conditioner is a fieldbus component that provides impedance
matching between the power supply and the fieldbus segment. (This
may be included as part of a fieldbus power supply.)

5.4 Wiring ST 3000 FF Transmitter Continued

Fieldbus Network · Fieldbus terminators - This component acts as a signal termination.

Components, Two are required for each fieldbus segment. One is connected at or
Continued
near each end of a network segment.
· Junction block - This is a terminal block used as a junction point for
fieldbus cable leads to individual devices.
· Fieldbus I.S. barriers - Limits the available power to the fieldbus
segment to eliminate explosion hazards. (Barriers must be designed
for fieldbus networks.)

Fieldbus Network There are various schemes that can be used to wire devices in a fieldbus
Wiring Schemes network. Devices can be connected:
· In a daisy-chain, (in parallel)
· To a bus, where the devices are attached in a multidrop scheme
· In a tree fashion, where devices are connected to a network segment
via a common junction block.

Daisy-Chain Wiring The fieldbus cable is routed from device to device in parallel along a bus
segment. The cable is interconnected at the terminals of each field
device. (This installation must be powered down to modify or replace
transmitter.) This scheme is illustrated in Figure 20.

Bus with Spurs In this scheme, field devices are connected to a bus by a length of
Wiring fieldbus cable called a spur (or drop). The spur can vary in length from
1 meter (3.28 ft.) to 120 m (394 ft.). Figure 21 shows devices and spurs
connected to a bus segment.

via a spur cable to a common junction block, terminal, or marshalling
panel. This scheme is practical if devices on the segment are well
separated, but in the general area of the same junction block. Figure 22

Fieldbus Network A number of factors limit the size of a fieldbus network:

Limitations 1. The cable type used in the wiring system limits the length of a
network segment. (See Fieldbus Cable Types.)
2. The number of field devices connected on a segment is limited
depending on:
- voltage of the power supply,
- resistance of the cable and
- current drawn by each device.
(See Voltage, Resistance and Current.)
3. Attenuation and distortion of the signal on the fieldbus due to:
- resistance of the cable,
- varying characteristic impedance along the cable,
- signal reflections from spur connections, and
- other factors that limit the size of a network segment.

Fieldbus Cable Types Various types of cable are useable for fieldbus network wiring. Table 16
lists the cable types. Please note that Type A is the preferred cable to
use for fieldbus; then type B, etc.

Table 16 Fieldbus Cable Types

5.4 Wiring ST 3000 FF Transmitter Continued

Voltage, Resistance Power supply output voltage, cable resistance and device current
and Current requirements limit the number of devices on a network segment.
1. The output voltage of the power supply must be considered when
building a fieldbus segment. Typical fieldbus devices require a
minimum of 9 volts to operate. (See power requirements for the
ST 3000 FF in Section 4.2.)
2. Resistance of the fieldbus cable produces a voltage drop along a
segment and must also be considered.
3. The device startup current as well as the operating current must be
considered, because some devices require considerably more current
when they are first powered up and begin to operate. (The ST 3000
FF does not require extra current at start up.)
The power calculation for a network segment should allow for these
factors (voltage, current and resistance), otherwise the network may not
start up when power is first applied.

ATTENTION Refer to Wiring Diagram #51309440 in Section 13 for current/resistance

wiring recommendations for the ST 3000 FF.

ATTENTION The operating power required by fieldbus devices varies by device type
and manufacturer. Please check the device specifications for the device
power requirements.

Number of Devices For the bus with spurs and tree wiring schemes, there are guidelines for
and Spur Length the length of spurs and the number of devices that can be connected on
these spurs. The guidelines established are only recommendations for
the maximum cable length to assure adequate signal quality. Spur
length depends upon:
· Cable type/characteristics/wire gauge, (cable types A, B, C, or D)
· Wiring scheme, (bus with spurs or trees)
· Number and type of devices, (are devices bus or self-powered and
are they suitable for I.S. applications).
In any fieldbus segment there may be a variety of cable and the quality
of existing cable may vary, therefore you should try to use the shortest
cable length possible.

ATTENTION If you are installing intrinsically safe field devices in hazardous areas,
there are additional things to consider. See Intrinsically Safe
Applications section.

5.4 Wiring ST 3000 FF Transmitter Continued

ST 3000 FF Wire Fieldbus signal communications and DC power are supplied to the
Connections transmitter using the same fieldbus twisted-pair cable.

Inside the electronics housing of the transmitter is the terminal block for
connecting external wiring as shown in Figure 23. Table 17 explains the
usage of the wiring terminals for fieldbus use.

Each transmitter includes an internal ground terminal to connect the

transmitter to earth ground. A ground terminal can be optionally added
to the outside of the electronics housing. While it is not necessary to
ground the transmitter for proper operation, we suggest that you do so to
minimize the possible effects of “noise” on the output signal and provide
additional protection against lightning and static discharge damage.
Note that grounding may be required to meet optional approval body
certification. Refer to section 3.2 CE Conformity (Europe) Notice for
special conditions.

Optional lightning protection (option LP) can be ordered for transmitters

that will be installed in areas highly susceptible to lightning strikes.
Figure 23 shows the 5-screw terminal block used when the lightning
protection option is ordered.

Intrinsically Safe Fieldbus barriers should be installed per manufacturer’s instructions for
Applications transmitters to be used in Intrinsically Safe (I.S.) applications.

The number of field devices on a segment may be limited due to power

limitations in hazardous area installations. Special fieldbus barriers and
special terminators may be required. Also the amount of cable may be
limited due to its capacitance or inductance per unit length.

6.5 Function Block Application Process

60 ST 3000 FF - Installation and Device Reference Guide 7/00

Function Block All fieldbus devices contain one or more Function Block Application
Application Process Processes (FBAP) as part of their device configuration. The Function
Block Application Process in the ST 3000 FF is a software application
that defines the particular characteristics of the transmitter. The FBAP
comprises function blocks, a transducer block, and a resource block, plus
other functions which support these blocks. Each function block
contains a set of operating parameters (some of which are user-
configurable) that define the operating characteristics of the transmitter.

Function blocks perform (or execute) their specific functions according to

a schedule. This schedule provides the sequence and timing of events
which occur within a device and also between other fieldbus devices.
This schedule is coordinated with the function block execution schedules
in the device and other fieldbus devices on the network.

Additional information on the FBAP contained in the ST 3000 FF is

found in Section 8, Function Block Application Description.

Default FBAP An FBAP containing default configuration parameters is resident in the

Configuration firmware of the transmitter and is loaded on power up. By using the NI-
FBUS configurator (or other fieldbus configuration) application, you can
create or make changes to a FBAP for the transmitter's process
application.

Device Configuration Configuring the ST 3000 FF results in:

· Function blocks that execute according to a user-defined schedule
· Measurements that are processed according to various user-
configurable parameters found within the function blocks
· An output "published" on the fieldbus network according to a user-
defined publishing schedule. The output then is available to other
fieldbus devices and function blocks.

Device Configuration Sample printout of a typical device configuration for ST 3000 FF

Example transmitters is given in Appendix B.

6.5 Function Block Application Process Continued

Fieldbus The ST 3000 FF transmitter is configured using a fieldbus configuration

Configuration application running on a operator station, PC or host computer. (The NI-
Application
FBUS configurator actually provides the means for you to configure the
FBAPs of fieldbus devices.) This configuration tool allows you to:
· Connect function block inputs and outputs according to the process
requirements
· Make changes to function block parameters according to the process
requirements
· Make changes to the schedule of function block execution.
· Write the FBAP changes to the device.
· Save the FBAP file.

Creating a New FBAP Again, all fieldbus devices contain one or more Function Block
Application Processes as part of their device configuration. Some or all of
a device’s function blocks may be used as a part of an FBAP. Also,
function blocks from a number of field devices may be connected as part
of an FBAP. Using a fieldbus configuration application you can create
and make changes to a FBAP according to your process application
requirements. The procedure in Table 22 outlines the tasks for creating a
typical FBAP file.

Table 22 Creating an FBAP file.

Step Task

1 Connect configurator/builder to network. Load and startup the fieldbus

configuration program on the host computer, PC or other operator
interface.

2 Connect fieldbus devices to the network. The configurator program will

Write Protect Feature ST 3000 transmitters are available with a “write protect feature”. It
consists of a hardware jumper located on the transmitter’s electronics
board and a software switch that you set to enable or disable the read and
write access to the transmitter configuration.

The jumper can be set to enable read only access (write protect) to the
transmitter’s configuration. When the jumper is in the read only (“R”)
position, the transmitter’s configuration parameters and calibration data
can only be read or viewed, (transmitter configuration is write
protected). When the jumper is set to “W”, configuration parameters
and calibration data can be written to the transmitter as well as viewed.

ATTENTION The jumper is factory set for read and write access (not write protected)
“W” position. See Figure 24 for the location of the write protect jumper.

NOTE: The write protect jumper is used in conjunction with the

FEATURE_SEL parameter (in the resource block) and it is
explained below.

Refer to Table 23 to set the write protect jumper.

Table 23 How to Set Write Protect Jumper

Step Action
1 Remove power to transmitter.

2 Loosen end cap lock and unscrew end cap from electronics side of

6.6 Setting Write Protect Feature Continued

Enabling Write Once the write protect jumper is set to the “R” position, you then set
Protect Feature HARD_W_LOCK of the FEATURE_SEL parameter. The write protect
feature is activated only when HARD_W_LOCK is set and the write
protect jumper is in the “R” position. The transmitter will remain write-
protected until the transmitter is powered down and the jumper is placed
in the "W" position and HARD_W_LOCK is cleared. See Table 25 for
truth table.

HARD_W_LOCK HARD_W_LOCK element of the FEATURE_SEL parameter acts as a

parameter switch to prevent changes to the transmitter configuration. When the
write protect jumper is set to the “R” position and HARD_W_LOCK is
set, any value stored in the transmitter’s non-volatile memory cannot be
changed. You can only read the parameter values from the device.
Normal block execution continues.

Simulation Jumper There is a second hardware jumper also on the transducer board which is
used for debugging communication problems independent of sensor
function. See Figure 24.

A simulation parameter in the AI block is used to aid in system debug if

the process is not running. A hardware jumper is provided to enable or
disable the simulate parameter. See Section 11.10 for details on setting
the simulation jumper.

7.3 Operation Considerations

Operation There are a number of considerations you should note when configuring
Considerations an ST 3000 FF to operate in a fieldbus network.

LAS Capability The ST 3000 FF is capable of operating as the Link Active Scheduler
(LAS). The LAS is a fieldbus device which controls traffic on the
network, such as controlling token-rotation and coordinating data
publishing. This fieldbus function is active in only one device at any
given time on a network. Devices which can be designated as the LAS
may be an operator station or a field device. The ST 3000 FF can be
designated as a LAS so that, in the event of a failure of the primary LAS,
control in the field could continue.

Please note that the ST 3000 FF does not support being configured as the
primary LAS, and therefore the LAS capability in the transmitter is
regarded as a "backup" LAS.

Special Non-volatile All function block parameters designated as Non-Volatile (N) in the FF
parameters and NVM specifications are updated to non-volatile memory (NVM) on a periodic
Wear-out
basis. NV_CYCLE_T parameter in the resource block specifies this
update interval.

To provide predictable restart behavior in the transmitter, the following

Non-Volatile parameters are updated to NVM each time they are written
over the fieldbus.
· MODE.TARGET for all blocks
· SP.VALUE for the PID block
Since these are user-written parameters, these additional updates to NVM
contribute negligibly to NVM wear out. However, user's are cautioned to
not construct control configurations where the above parameters are
written continuously (via a computer application for example) or at rates
greater than the NV_CYCLE_T interval. This consideration will help
minimize the possibility of NVM wear-out.

In the case of MODE this should not be a problem. When users wish to
provide set-points to the PID block via a computer application, users
should use RCAS mode with its corresponding setpoint value RCAS_IN.
RCAS_IN is updated only at the NV_CYCLE_T update rate and this
mode supports full shedding functionality and PID initialization
necessary for a robust application.

7/00 ST 3000 FF - Installation and Device Reference Guide 69

7.3 Operation Considerations Continued

Mode Restricted Some block parameters have restrictions on having write access to them.
Writes to Parameters These are specified in the FF specifications. Writing to certain AI block
and PID block parameters is restricted based on the block’s Target and/
or Actual mode. The listing of these parameters are given in the AI block
description and PID block descriptions in Section 8.

70 ST 3000 FF - Installation and Device Reference Guide 7/00

7.4 Monitoring Local Meter Display

Local Meter Display The Local Meter provides a means of monitoring the transmitter process
Description values at the transmitter. The display shows the read-only output of the
transmitter, specifically the value and status of the AI block OUT
parameter. The value is shown as % of range (shown on the meter
bargraph segments) and user-selected engineering units (shown on the
numeric display). Status on the display is shown using a number of
status indicators and/or segments of the digital readout.

When showing engineering units, the values are auto-ranged for the
most precision available within the limits of the display. The units are
shown as configured in the transmitter and are determined by setting the
OUT_SCALE parameter (in the AI block). If the engineering units are
not supported by the meter, or if the units are unknown, the display
shows no units indication. Stick-on labels can be applied to the display
to indicate units that are not supported by the meter. See Table 27. (See
Subsection 8.6 for additional details on local meter display values.)

Display Self-test The meter runs a brief self-test whenever power is applied to the
transmitter. You can check the status of all the indicators on the local
meter LCD display by cycling power to the transmitter. All the display
indicators are lit for two seconds during the self-test. Figure 25 shows a
local meter display with all display indicators lit. Table 27 gives a brief
description of all the possible indicators when in operation.

Changing Output The local meter display can be changed to display output in user-
Display selected engineering units. Table 30 lists the steps to select the
engineering units for your process application. A block diagram of the
AI block is shown in Figure 28 in Section 8.6 which may aid in
performing the procedure.

Table 30 Changing Local Meter Display Units

Step Action
1 At the operator station, access the device tag of the transmitter.
2 Set the AI block MODE_BLK parameter to O/S (Out Of Service).
3 Set the OUT_SCALE.UNITS_INDEX to the desired engineering unit
to be shown on the meter display.
4 Set parameters OUT_SCALE.EU_100 and OUT_SCALE.EU_0 to a
range for the unit selected in step 3.
5 Set parameter L_TYPE to INDIRECT
This allows the OUT_SCALE parameter values to be shown on
the meter display.
Also, setting L_TYPE to INDIRECT/SQRT allows you select
flow units for display.
6 Set the following parameters to values which do not exceed the
OUT_SCALE.EU_100 and .EU_0 parameter values:
HI_HI_LIM
HI_LIM
LO_LO_LIM
LO_LIM
For example, If OUT_SCALE.EU_100 = 400 and
OUT_SCALE.EU_0 = 0
Then: HI_HI_LIM and HI_LIM must be < 400 and
LO_LO_LIM and LO_LIM must be > 0.

7 Write the changes to the transmitter.

8 Change AI block parameter MODE_BLK.ACTUAL = Auto
9 At the transmitter, verify that the display shows the proper
engineering units.
NOTE: Depending on the selected engineering units, you may need
to attach the appropriate stick-on label to the display faceplate
(Honeywell drawing number 30756918-001).

About this Section This section provides information about the construction and contents of
the ST 3000 FF Function Block Application Process (FBAP); (This is
the application that defines transmitter function and operation in the
process application.) This information is provided to give some
understanding of the elements that make up the configuration of the
device application.

For More Information FBAP elements are described as they apply to the ST 3000 FF transmitter
on FBAP in the following sections. More detailed information can be found in
Fieldbus Foundation documents, FF-890 and FF-891 Foundation
Specification Function Block Application Process Parts 1 and 2.

8.2 Function Block Application Process (FBAP)

Function Block The Function Block Application Process (FBAP) (or application)
Application Process comprises a set of elementary functions which are modeled as function
(FBAP)
blocks (block objects). These block objects provide a general structure
for defining different types of device functions (such as analog inputs,
analog outputs and proportional integral derivative (PID) control).

The FBAP also contains other objects that provide other device
functions, such as furnishing alarm information, historical data, and
links to other blocks for transferring data.

FBAP Elements The key elements of the FBAP are device objects which are of the
following object types:
· Block objects and their parameters
(consisting of the following block types)
- Resource blocks
- Transducer blocks
- Function blocks
· Link Objects
· Alert Objects
· Trend Objects
· View Objects
· Domain Objects

Device Objects Link objects allow the transfer of process data from one block to
another. View, Alert and Trend objects provide a way of handling
function block parameters for operator interface of views, alarms and
events, and historical data. A brief description of these objects is
presented in the following sections.

8.3 Block Description

7/00 ST 3000 FF - Installation and Device Reference Guide 79

Block Objects Blocks are some of the key elements that make up the FBAP. The
blocks contain data, (block objects and parameters) which define the
application, such as the inputs and outputs, signal processing and
connections to other applications. The ST 3000 FF transmitter
application contains the following block objects:
· Resource block
· Transducer block
· Two Function blocks
- Analog Input (AI) function block
- Proportional Integral Derivative (PID) Controller function block

Table 31 briefly describes the operation of these blocks.

Table 31 Function Block Application Process Elements

Block Type Function

Resource Contains data which describes the hardware (physical)

characteristics of the device.
Such as : MANUFAC_ID
DEV_TYPE
Device firmware revision Information
The resource block does not perform any action, but
contains parameters which support application
downloads.
Transducer De-couples the function blocks from I/O devices such as
sensors, actuators and switches.
The transducer block interfaces with the sensor
hardware and provides either a direct pressure
measurement or a calculated value to the AI function
block. This block also contains sensor-specific
parameters for calibration and diagnostics.
Function Blocks In general, function blocks perform basic automation
functions that are integral to automated control and
processing operations. The ST 3000 contains two
function blocks, one Analog Input and one PID block.
Analog Input (AI) The analog input function block performs engineering
units scaling, square root, alarming, and publishing of
the PV on the bus.
PID Controller Performs standard or robust proportional integral
derivative algorithm used in closed loop processing.

†† CAUTION These values are for the sensor only! The maximum pressure allowed to
Maximum Values for any transmitter with remote seals, flange, or fittings must be limited to
SENSOR_MAX_SP & either the pressure rating of the transmitter sensor or the pressure rating
SENSOR_MAX_OVP of the remote seals, flange, and fittings, whichever is lower.

Level Calculation The ST 3000 FF has the ability to put the measured pressure value through
fifth-order polynomial equation. This calculation allows the transmitter to
closely approximate the level of an irregularly shaped tank or vessel. The
following pages describe the level calculation along with an example of its
use.

Enabling the Level The CHANNEL parameter in the Analog Input block is used to select the
Calculation measurement value from the transducer block (which is either
PRIMARY_VALUE or CALC_VAL).

· When CHANNEL = 1, PRIMARY_VALUE is selected as input to

the AI block.
· When CHANNEL = 2, the level calculation is enabled and
CALC_VAL is the selected input to the AI block which is the direct
pressure measurement value from the sensor.

Therefore, if you wish to use the level calculation, you set the AI block
CHANNEL parameter to equal 2.

Parameters used in The following parameters are used do the level calculation and these
the Level Calculation values are derived from your particular application:
· LEVEL_COEFF contains an array of floating point values
(coefficients) to be used in the equation.
· TANK_RANGE contains the upper and lower ranges of the tank
measurements (i.e. for a full and empty tank) and the engineering
units

LEVEL_COEFF The LEVEL_COEFF parameter will contain coefficients used in the

Parameter polynomial level equation. These coefficients must generated by you
for your application. Also these values must be such that the result of
the calculation is expressed in percent.

ATTENTION If the AI block's XD_SCALE is not configured with the engineering

units in percent value (and CHANNEL = 2), then a block configuration
error will be generated in the AI block and it will remain in Out of
Service (O/S) mode.

The polynomial can also be used for measuring flow,

Where flow = f (Dp).

TANK_RANGE The TANK_RANGE parameter is configured with the upper and lower
Parameter range values of the pressure coming from the tank measurement. This
must also take into account the head pressure of any fill fluid in remote
seal tubing (wet legs).

Level Calculation The level is calculated in the following way:

Formula
V = 100 • [C0 + (C1 • H1) + (C2 • H2) + (C3 • H3) + (C4 • H4) + (C5 • H5)]

where: V = Volume (%)

H = height of process tank fluid, in fraction (0.0 - 1.0)
of TANK_RANGE
Ci = LEVEL_COEFF[i]

NOTE: You must provide the coefficients for this equation, as the
transmitter has no knowledge of the shape of the tank.

The result of the calculation, V is placed in CALC_VAL and passed to

the AI block. The engineering units are always expressed in percent (%).

8.5 Transducer Block Continued

Example for Using The following paragraphs describe, using an example, how to determine
Level Calculation the values used to configure LEVEL_COEFF and TANK_RANGE.
Following the example are some measurement examples.

Step 1 Given the vessel shown below, determine the measurements of the
vessel and calculate the theoretical polynomial coefficients. To do this
use a height of “1” for the vertical distance, rather than the actual
distance, representing the pressure range to be configured in
TANK_RANGE. Remember that the polynomial calculates volume, not
simply vessel shape, as a function of level.

C
B

The actual vessel measurements are: A = 20 ft., B = 30 ft., C = 40 ft.

The theoretical coefficients, using a height of “1”, are derived to be:

C0 = 0
C1 = B • C = 1200
C2 = -0.5 • B • C = -600
C3,C4,C5 = 0

Step 2 Divide all theoretical coefficients by the maximum volume of the vessel,
again using the height of ”1” in the calculations. These become the
actual coefficients.

Maximum volume = 0.5 • “1” • B • C = 600

So, the actual coefficients are:
C1 = 1200/600 = 2
C2 = -600/600 = -1

8.5 Transducer Block Continued

Step 3 Configure the transducer block parameters LEVEL_COEFF and

TANK_RANGE.

So, LEVEL_COEFF is configured with the coefficients calculated above

in Step 2.

TANK_RANGE may be configured as described below, where

TANK_RANGE.EU_0 = actual pressure when tank is empty
(Pempty)
TANK_RANGE.EU_100 = actual pressure when tank is full
(Pfull)
TANK_RANGE.UNITS_INDEX = pressure units used

Configuring TANK_RANGE.EU_0 -
The lower range (pressure measurement when tank is empty) is
configured in TANK_RANGE.EU_0 and can be either of the following:

· Actual measured pressure when tank is empty, or

· H2 • Sf • -1

Where,
H2 = Height of fixed reference leg (vertical height between upper and
lower tank connections), in units configured in SENSOR_RANGE
subindex 3 (units index)
Sf = Specific gravity of fill fluid
(e.g. Sf of silicon "DC200" = 0.94)

Configuring TANK_RANGE.EU_100 -
The upper range (pressure measurement when tank is full) is configured
in TANK_RANGE.EU_100 and can be either of the following:

· Actual measured pressure when tank is full, or

· H1 • SL

Where,
H1 = Height of variable head, in units configured in SENSOR_RANGE
subindex 3 (units index)
SL = Specific gravity of measured liquid
(e.g. SL of water at 60 °F is 1.00)

8.5 Transducer Block Continued

Step 4 If desired, configure the AI block to convert the percentage (%) value
coming from the transducer block to engineering units. For example, if
you want to see the value in gallons rather than percent, configure the
following parameters as described below:

XD_SCALE.EU_0 = 0
XD_SCALE.EU_100 = 100
XD_SCALE.UNITS_INDEX = Percent

OUT_SCALE.EU_0 = 0
OUT_SCALE.EU_100 = Volume of the tank representing 100%
OUT_SCALE.UNITS_INDEX = Desired output engineering units

CHANNEL = 2
L_TYPE = Indirect (2)

If total vessel volume = 0.5 • A • B • C = 12000 cu. ft. = 89766 gallons,

Then configure
XD_SCALE - as described above
OUT_SCALE.EU_0 = 0
OUT_SCALE.EU_100 = 89766
OUT_SCALE.UNITS_INDEX = gallons

Measurement
Examples Given: Pempty = 0
Pfull = 100 PSI

If: Input pressure = 50 PSI

Then: V = 100 • [ (2 • 50/100) + (-1 • (50/100)2) ]
= 75 %
and: AI.OUT = 67324.5 gallons

If: Input pressure = 25 PSI

Then: V = 100 x [ (2 • 25/100) + (-1 • (25/100)2) ]
= 43.75 %
and: AI.OUT = 39272.625 gallons

Transmitter Output Viewing certain parameters and their values in the transmitter and
Signal and Status understanding their relationship to each other are helpful in
understanding transmitter output signal and status. The following
paragraphs and tables describe transducer and AI block parameters
which directly determine the way the transmitter output is presented.
Refer to Tables 39 and 40 and the AI block diagram for the following
discussion.

Pressure Sensor The characterized ST pressure signal is developed in the transducer

Signal block as PRIMARY_VALUE. This signal uses the elements in
PRIMARY_VALUE_RANGE in determining the engineering units, the
decimal places for display and the high and low scale of the value.

This signal becomes PV value in the AI block and uses the elements of
OUT_SCALE in determining the units, decimal places and the high and
low scale values for PV. The signal exits the AI block as OUT value
which also uses the elements of OUT_SCALE.

This Parameter Contains . . .

PRIMARY_VALUE The status and value of the pressure sensor measurement.

PRIMARY_VALUE_RANGE Elements used to display the PRIMARY_VALUE parameter. The
elements are:

· Engineering units used to display the value (UNITS_INDEX).
· Decimal places used to display the value (DECIMAL).

PRIMARY_VALUE The high and low scale values of PRIMARY_VALUE_RANGE

Status (EU_100 and EU_0) should be set to the maximum allowable range of
the pressure sensor signal. So, that

signal within the range of PRIMARY_VALUE_RANGE, the
PRIMARY_VALUE status is
Good Non Cascade::[alarm status]:Not Limited.
· When the signal exceeds the range of PRIMARY_VALUE_RANGE,
the PRIMARY_VALUE status becomes
Uncertain::[alarm status]:Engineering Units Range Violation, &

This Parameter Contains . . .

OUT The status and value of output from the AI block.

OUT_SCALE Elements used to display the OUT parameter. The elements are:
· High and low scale values (EU_100 and EU_0).
· Engineering units used to display the value (UNITS_INDEX).
· Decimal places used to display the value (DECIMAL).
PV The status and value of PV. This is usually the same as OUT and the
same value as PRIMARY_VALUE in the transducer block.
XD_SCALE Elements used to display the value obtained from the transducer block.
The elements are:
· High and low scale values (EU_100 and EU_0).
· Engineering units to display the value (UNITS_INDEX)
· Decimal places to display the value (DECIMAL).
NOTE: When CHANNEL = 1, XD_SCALE.UNITS_INDEX must contain
the same units as PRIMARY_VALUE_RANGE.UNITS_INDEX in
the transducer block.
When CHANNEL = 2, the XD_SCALE.UNITS_INDEX must be set
to engineering units of percent.
L_TYPE The state (Direct or Indirect) which values are passed from the transducer
block to the AI block.
· When L_TYPE = Direct.
Values are passed directly from the transducer block to the AI block.
(No units conversion.)
· When L_TYPE = Indirect.
Values from the transducer block are in different units, and must be
converted either linearly (Indirect) or in square root (Ind Sqr Root)
using the range defined by the transducer and the OUT_SCALE range.

Continued on next page

7/00 ST 3000 FF - Installation and Device Reference Guide 99

8.6 Analog Input Function Block Continued

XD_SCALE Range In the AI block, XD_SCALE values are used when L_TYPE is set to
Indirect which converts the signal to other units. (See L_TYPE in Table
39.) The high and low scale values of XD_SCALE (EU_100 and
EU_0) define the range over which the AI OUT will show Good status.

· When L_TYPE is set to either Indirect or Direct, XD_SCALE units

must match the transducer PRIMARY_VALUE_RANGE units
(CHANNEL = 1).
Therefore, the high and low scale values of XD_SCALE would
normally be set equal to or within the transducer
PRIMARY_VALUE_RANGE range.

· When L_TYPE is set to Direct, it is recommended that XD_SCALE

and OUT_SCALE should contain the same values

PV Value The AI block PV value is the same as the transducer block

PRIMARY_VALUE

AI OUT AI in Manual Mode - When the AI block is in manual mode, OUT can
be written as a fixed value between -10% and +110% of the
OUT_SCALE range. OUT values between 0 and 100% will show a
status of Good. OUT values outside the range will show a status of
Uncertain. The “limited” field will be marked as Constant for all values.

PV shows the live pressure signal in manual mode.

AI in Auto Mode - L_TYPE determines whether the signal is taken

directly from the transducer block and passed to the AI block output
(L_TYPE = Direct) or converted into different units before it is passed
to the AI block output (L_TYPE = Indirect or Ind Sqr Root).
OUT_SCALE determines the units conversion of the signal presented to
the output.

· When L_TYPE equals Direct, OUT is the same as the value passed
from the transducer block.

· When L_TYPE equals Indirect, the PRIMARY_VALUE is

converted to percent of XD_SCALE and that value is set equal to
percent of OUT (FIELD_VAL = %). The OUT in % is re-ranged to
a value using the OUT_SCALE.

Table 43 Honeywell PID Parameters

Parameter Name Description/Parameter Contents
PID_FORM Configuration parameter specifies the IDEAL or ROBUST PID equation to be used:
· IDEAL PID (default). Non-Interactive form of a three mode control equation
that provides Proportional, Integral and Derivative control action. Linear and
non-linear gain parameters are available.
· ROBUST PID. The same as Ideal PID. Additionally, the equation supports a
user-configurable lag filter applied to calculated output value. (See OUT_LAG
parameter.) Linear and non-linear gain parameters are available.
ALGO_TYPE Configuration parameter specifies algorithm type which can be A, B, or C:
· Type “A” equation where Proportional, Integral and Derivative act on ERROR.
· Type “B” equation where Proportional and Integral act on ERROR and
Derivative acts on PV.
· Type “C” equation where Integral acts on ERROR and Proportional and
Derivative act on PV.
OUT_LAG Time constant of single exponential LAG filter applied to the OUT parameter
(primary output).
Units (in seconds). For Ideal PID equation the lag filter is fixed at 1/16 and is not
configurable.

Parameter Name Description/Parameter Contents
GAIN_NLIN Dimensionless gain factor. When the gain factor is multiplied by absolute value of
the error and added to the linear GAIN, the result is a gain response which is
proportional to the deviation.
Default is zero resulting in no response due to non-linear gain action.
GAIN_COMP The composite gain quantity including both linear and non-linear gain parameters.
Read only parameter.
ERROR_ABS Absolute value of the difference between PV and working setpoint. Read only
parameter.
WSP Working setpoint. This is the setpoint value after absolute and rate limits have been
applied. Deviation alarms are computed on this value. Read only parameter.
BLOCK_TEST An internal Honeywell test parameter. See Section 11.7 and 11.8 for more details.

8.7 PID Function Block Continued

PID Block Description PID Control Function Block is an algorithm that produces an output
signal in response to the measured variable and the setpoint. The PID
function block allows you to choose either a standard PID control
equation (Ideal) or a robust PID equation defined by Honeywell. This
selection is defined in the PID_FORM parameter.

The output has three terms: Proportional, Integral and Derivative. The
output is adjusted by tuning constants. There are three tuning constants
in the Ideal PID equation. The robust PID uses four tuning constants.

1. GAIN is the tuning constant of the Proportional term.

2. RESET is the tuning constant of the Integral.
3. RATE is the tuning constant of the Derivative. RATE is usually
modified by a lag, which is set at some fixed ratio higher than the
rate time, to create a rate gain. There is no lag with the rate in this
implementation.
4. OUT_LAG is the fourth tuning constant used in the robust PID, it
adds roll off to the output response. The action is similar to PID
with rate gain.

PID Ideal and PID The Ideal equation is a parallel or non-interacting implementation of PID
Robust control using three tuning constants. It automatically fixes OUT_LAG
to 16 times the RATE time constant. This produces response
characteristics equivalent to the algorithms used in TPS products.

The Robust equation is the same parallel implementation of ideal PID

control but allows the engineer to set the OUT_LAG and effectively
change the rate gain.

ALGO_TYPE is a configuration parameter that contains one of three

selected algorithm types, A, B, or C.
Where:
· A - RATE, GAIN and RESET all act on the error between set point
and measured variable.
· B - RATE acts on the measured variable only, GAIN and RESET
use the error.
· C - RATE and GAIN act on the measured variable only, and
RESET uses the error.

8.7 PID Function Block Continued

PID Tuning Table 44 lists the valid ranges for the tuning parameters for the PID
Parameters block. Note that OUT_LAG parameter is not configurable when Ideal
PID is selected (PID_FORM = 1) and can be configured when Robust
PID is selected (PID_FORM = 2).

The values given for these tuning parameters are valid under the
following conditions:
· The values assume that the minimum configurable PID function
block execution period (Ts) is 0.125 seconds.
· Algorithm type setting (i.e. A, B, or C) has no effect on the
validation of these tuning parameters.
· The PID function block will reject all values outside these ranges.

In this case, the attribute indicates that it is a contained parameter and may
not be referenced by link objects for use as an input to function blocks.
Store Indicates the type of memory where the parameter is stored:
S - Static. Writing to the parameter changes the static revision counter
ST_REV
N - Non-volatile. Non-volatile. Non-volatile parameters are stored internally
to actual non-volatile memory on periodic basis to protect the life of the
memory. This interval is set by the resource block parameter
NV_CYCLE_T at 15 minutes (displayed as 28800000 in 1/32
milliseconds). It cannot be changed by the user. Parameter must be
retained during a power cycle.

Column Title Meaning
Attribute
Size The number of octets.

Valid Range Range of valid values the parameter is restricted to for use in the function block.
For bit strings:
0 (zero) is always valid as the state of a bit and is the inverse of the
described value.
For enumeration:
0 (zero) means that the value is invalid. This is required for initialization of
an unconfigured block.
Plus or minus infinity (+INF or -INF) may be included in the valid range to
indicate that it is permissible to use them to turn off a limit comparison,
such as an alarm limit.
Initial Value The default value inserted when the device is restarted with defaults. All limits
are set to plus or minus infinity (+INF or -INF), which is the same as no limit. All
dynamic values are initialized to zero.

Perm. Defines the setting of the GRANT_DENY parameter that allows write access to
Permission the parameter, for interface devices that obey this parameter.
Mode Indicates the lowest priority target mode required to allow a change to the
parameter. The actual mode must match the target mode, so that the block is
not in another mode than that chosen by the operator. Scaling changes are
protected by mode because the block may be using scaling to calculate its
output.

8.9 Link Objects

Background The function blocks configured to control a process are linked, or

connected by objects within the devices. These links allow you to
transfer process and event data from one block to another. These links
are defined through link objects.

Link Object Link objects define Virtual Communication Relationships (VCRs)

Description which are used to communicate between blocks. Link objects contain
information needed to define communication links between function
blocks and interface devices and other field devices. This information
may be read by an interface device that will access information in field
devices.

Example For example, link objects may be used to link the output parameter of
one function block to the input of another block, or a trend object, or
alert object.

ST 3000 Link Objects Link objects are used for alarms and events, function block linking and
trending. In the ST 3000 FF there are links objects defined for:
· The PID block (6 input parameters)
· The PID and AI blocks (3 output parameters)
· Every alert object
· Every trend object
Table 51 lists the link objects defined in the ST 3000 FF

8.10 View Objects

Description View objects define a grouping of parameters that can be read over
fieldbus using a single message. Typically, view objects are used by a
host device to retrieve certain data efficiently for display, without loading
down the network. Some host systems may be capable of being "tuned"
during configuration by using the knowledge by which parameters may be
accessed in the same view object group.

At least four view objects (View1, View2, View3 and View4.) are defined
for each resource block, function block, and transducer block in a device
(for a total of 16 views.) Block parameters can be grouped and displayed
depending on how the data is to be used. Four standard view objects
(groups) are defined for accessing the following types of information:
1. View1 - used to display dynamic operation data
2. View2 - used to display static operation data
3. View3 - used to display all dynamic data
4. View4 - used to display other static data.

ST 3000 View Objects In the ST 3000 FF, four view objects are defined for each of the four
blocks - for a total of 16 view objects. Some parameters are accessible in
all four views, while others are available in one view. Tables 52 through
55 list all the parameter objects in the transmitter.
· A number in the View columns of the table indicates the number of
view(s) in which a parameter is visible, (only if a number is shown
in the column for that parameter.)
· The number indicates the number of bytes of data which is shown
for that parameter in a view.
· The TOTAL line in each table shows the size of each view in bytes.

8.11 Alert Objects

Description Alert objects support the reporting of alarms and update events to
operator interface devices and other field devices. Alert objects are used
to communicate notification messages when alarms or events are
detected. These objects are defined in the function block application.

Alert objects contain:

· The value of the data
· Block index (a number)
· Alert key (parameter)
· Time stamp
· Priority

ST 3000 Alert Objects Three alert objects are defined in the ST 3000 FF for event and alarm
reporting.
- 1 for events (used for static parameter update events)
- 1 for discrete alarms (used for block alarms)
- 1 for analog alarms

7/00 ST 3000 FF - Installation and Device Reference Guide 123

8.12 Alarm and Event Reporting

Alarms, Events and Alarms are generated when a block leaves or returns from a particular
Alert Objects state. (A function block changes state and generates an alarm that
indicates high tank pressure.)

Events are instantaneous occurrences that are significant to block

execution or operation of a process. ( For example, a change in the state
of a variable generates an event message.)

Alarms and event messages are communicated to operator interfaces and

other devices using alert objects.

Alarm Messages · Alarm messages contain a:

- Time stamp
- Snapshot of the data
- Specified priority
· Alarms must be confirmed, otherwise the block will continually
report the alarm.
· Another alarm is generated when alarm conditions clear.
· Acknowledgment of alarms may be necessary to satisfy operation
requirements

Event Messages · Event messages contain a time stamp

· Events also must be confirmed, otherwise the block will continually
report the event.
· Acknowledgment of event may be necessary to satisfy operation
requirements

124 ST 3000 FF - Installation and Device Reference Guide 7/00

8.13 Trend Objects

Description Trend objects support the management and control of function blocks by
providing user access to history information. Trend objects provide for
short term history data to be collected and stored within a resource. The
collected data may be input and output parameters, and status
information from selected function blocks. Trend objects are available
anytime for you to view.

Trend Data Types Trend record data may include one of these types of data -
· analog
· discrete or (not used in ST 3000 FF)
· bit string (not used in ST 3000 FF).
It is important that the proper trend data type be chosen to match the data
type being recorded. Trend information may be used in support of
trending in interface devices or by function block objects that require
historical information.

Trend Objects Trend objects:

· Provide short term history data
· Track both values and status
· Track and hold the last 16 values
· Allow user-defined sampling rate
· Allow efficient transfer of large amounts of data.

ST 3000 Trend The ST 3000 FF has two defined trend objects for analog data:
Objects - one for the AI function block
- one for the PID function block.

8.14 Domain Objects

Description Domain objects support download services which are used to download
applications to a device. Standard generic download services (defined
by Fieldbus Foundation) are used in the domain object of the ST 3000
FF.

8.15 Device Description (DD)

Overview Standardized definitions are used to support and describe application

process objects. Two of these standardized "tools" used to describe these
objects are the Object Dictionary (OD) and the Device Description
(DD).
The Object Dictionary and the Device Descriptions define and describe
the network visible objects of a device, such as function blocks and
block parameters. These “tools” try to provide a consistency in
understanding and describing these objects in device applications.
See also Object Dictionary description in the following section.

Device Description A typical DD contains information about the device parameters and
Contents operation, such as:
· Attributes, like coding, name, engineering unit, write protection,
how to display, etc.
· The menu structure for listing parameters, including names of menus
and submenus.
· The relationship of one parameter to others
· Information about help text and help procedures
· Maintenance, calibration and other necessary operation information.

Standard and Device- Standard DD descriptions for function blocks and transducer blocks are
Specific DD maintained by the Fieldbus Foundation. These descriptions can be used
as part of a field device DD by manufacturers to describe the standard
features of their devices. Device-specific descriptions are developed by
manufacturers to describe custom features which are unique to that
particular device.
These two types of DDs (the standard and device-specific) can then be
combined to provide a complete DD for the field device.

Device Descriptions A Device Description provides a clear and structured text description of
and ODs a field device. The descriptions found in a DD supplement the object
dictionary definitions of device applications. So, an OD description used
in conjunction with the DD will provide a complete detailed description
of the device operation.

7/00 ST 3000 FF - Installation and Device Reference Guide 127

8.15 Device Description (DD) Continued

Access to Field DDs can be loaded into the device that it describes, or stored on an
Device DD external medium, such as a floppy disk or CD. You then can access this
information through an operator station and read the DD directly from
the device or from the floppy disk.
You can use the DD to determine what information is available from the
device, what rules must be applied when accessing the information and
how the information can be displayed to you.

Standardized The use of standardized descriptions and definitions to describe device

Descriptions and application processes promotes the interoperability of fieldbus devices.

8.16 Object Dictionary (OD)

Overview The Object Dictionary (OD) is one of a number of standardized “tools”

used to describe and define Application Process (AP) objects, (function
blocks, block parameters, alert objects, etc.). The OD is used in
conjunction with standard and device-specific Device Descriptions
(DD) to provide a complete description of the device’s application
process.

Device Descriptions contain standard and device-specific text

descriptions of function blocks and block parameters in device
applications. See Device Description also in the previous section.

Object Dictionary AP objects are described in the Object Dictionary (OD). The OD is
Description comprises a series of entries, each describing an individual AP object
and its message data. The message data may consist of a number of
characteristics defined for that particular object.

The OD allows the FBAP of a device to be visible to the fieldbus

communications system.

OD Entries OD entries are assigned an index by the AP. The index serves as a
means of identification and location of individual objects. The entries in
the Application Process OD are organized as follows:
Index 0 - Object Dictionary Description - Describes overall
structure of the OD.

Index 1-255 - Reserved for descriptions of data types and data

structures used by the AP. (There are a number of
standard data types and data structures already defined as
part of fieldbus foundation specifications.)

Index starting at 256 - Entries for AP objects defined by the

application. These entries contain the records and
parameters for the various blocks that make up the AP.
Also included are alert, trend, view, link, and domain
objects which are defined by the AP.

To Calculate Index To calculate the index of any block parameter or object, add the index in
number of an Object the block's parameter (or object) list to the index of the block's record in
the list above. For example:

OUT: Index of 8 in the AI block parameter list, (Table 31)

AI's block record is at index 257 in the OD (Table 41)
Therefore, OUT of the AI block is at index 257 + 8 = 265
in the OD.

System Application Each link in a fieldbus network contains an Application Clock Time
Clock Time Publisher responsible for distributing Application Time on the link.
Synchronization
A clock synchronization message is periodically sent by the time
publisher to all fieldbus devices. The application clock time is
independently maintained in each device based on its own internal
crystal clock.

Clock synchronization provides the capability for devices to time stamp

data (events and alarms when they occur).

Sync and Scheduling These objects are used by system management to provide application
Objects clock synchronization and macrocycle scheduling for the device. Table

Device ID, Tag Name Each fieldbus device on the network is uniquely identified by:
and Device Address · Device ID which is set by the manufacturer to identify the device.
· Device Name (Tag) - set by you to identify operation.
· Device Address - a unique numerical address on the fieldbus
segment. Address may be set automatically by system management.

Automatic Device Assignment of physical device addresses is performed automatically by

Address Management system management.
1. The sequence for assigning a physical address to a new device is:
2. A physical device address is assigned to a new device. This may be
done off-line before the device is installed on the fieldbus network.
(The address can be preconfigured at the factory or set by you.)
3. The device is connected to the bus and uses default address 248 to
251. If no physical device name is set, the manufacturer’s device ID
is used.
4. System management assigns an unused address to the new device.
Assignment is done automatically or by you.

Function Block The SMIB contains a schedule, called the Function Block Schedule, that
Scheduling indicates when that device's function blocks are to be executed.
System Management schedules the start of each function block relative
to the macrocycle of the device. The macrocycle represents one
complete cycle of the function block schedule in a device. The
macrocycles of all devices on the link are synchronized so that function
block executions and their corresponding data transfers are synchronized
in time.

Using the configurator software, the device's function block schedule

can be configured.

Function Block There are four scheduling objects defined in the ST 3000 FF. Any
Scheduling Objects function block can be configured in one or more scheduling objects. By
default, the first scheduling object is assigned to the AI block and the
second is assigned to the PID block. Table 63 lists the function block
scheduling objects with their object directory index and default values.

Maintenance Routines The ST 3000 transmitter itself does not require any specific maintenance
and Schedules routine at regularly scheduled intervals. However, you should consider
carrying out these typical inspection and maintenance routines on a
schedule that is dictated by the characteristics of the process medium
being measured and whether blow-down facilities or purge systems are
being used.

• Clear the piping of sediment or other foreign matter
• Clean the transmitter’s pressure chambers including the barrier
diaphragms

9.3 Inspecting and Cleaning Barrier Diaphragms

Background Depending on the characteristics of the process medium being measured,

sediment or other foreign particles may collect in the process head
cavity/chamber and cause faulty measurement. In addition, the barrier
diaphragm or diaphragms in the transmitter’s meter body may become
coated with a residue from the process medium. The latter is also true
for external diaphragms on flange mount and remote seal type
transmitters.

In most cases, you can readily remove the process head or heads from
the transmitter’s meter body to clean the process head cavity and inspect
the barrier diaphragm or diaphragms. For flange mount and remote seal
diaphragms, you may only need to run a purge line in the tank to rinse
off the face of the diaphragm.

Procedure The procedure in Table 65 outlines the general steps for inspecting and
cleaning barrier diaphragms. You may have to modify the steps to meet
your particular process or transmitter model requirements. Figure 30
shows an exploded view of a DP transmitter’s meter body for reference.

Table 65 Inspecting and Cleaning Barrier Diaphragms

Step Action

1 Close all valves and isolate transmitter from process. Open vent in
process head to drain fluid from transmitter’s meter body, if required.

ATTENTION We recommend that you remove the transmitter

from service and move it to a clean area before taking it apart.

2 Remove nuts from bolts that hold process head or heads to meter
body. Remove process heads and bolts. See Figure 30.

3 Remove O-ring and clean interior of process head using soft bristle
brush and suitable solvent.

4 Inspect barrier diaphragm for any signs of deterioration or corrosion.

Look for possible residue and clean if necessary.
NOTE: If diaphragm is dented, has distorted convolutions or radial
wrinkles, performance may be affected. Contact TAC for
assistance.

ATTENTION
• We recommend that you install a new O-ring whenever a process
head is removed for cleaning.
• The process head for a GP or AP transmitter with single-head
design has two O-ring grooves. A large one which is 2 in (50.8
mm) in diameter and a small one which is 1.3 in (33 mm) in
diameter as shown in the following illustration. For high-pressure
applications, be sure to use a small O-ring in the smaller/inner
groove. On other models of GP or AP transmitters, use a large O-
ring in the larger/outer groove. Never use both O-rings together.

9.6 Code Download

Code Download Utility A code download may be recommended to upgrade the transmitter
firmware. A download utility program is used to perform the upgrade.
A code download also updates other files necessary for proper operation;
specifically, new versions of the Standard Dictionary and Device
Description files are loaded on the host computer. These files are
compatible with the “new” code.
Table 69 outlines the procedure for code download on a ST 3000 FF
transmitter using the “Honeywell FF Products Download Application”.

WARNING A code download can be performed on an active live control loop.

Prepare the control loop by setting the final control device to a safe state.
The transmitter will be off-line for about 30 minutes. When the
download is complete, the transmitter will revert to default settings, so
before you download save the present configuration.

Table 69 Code Download Procedure

measurement range. It also covers the procedure for resetting calibration
to factory default values as a quick alternative to measurement range
calibration.

7/00 ST 3000 FF - Installation and Device Reference Guide 163

10.2 Overview

About Calibration Your transmitter was factory calibrated to its standard range or a range
specified on the purchase order. So there should be no need to recalibrate
the transmitter during installation.

When recalibration is required, we recommend that you do a bench

calibration with the transmitter removed from the process and located in a
controlled environment to get the best accuracy.

Calibration Sources ST 3000 FF transmitter can be calibrated to a number of sources. The

calibration values can be set, cleared, restored to original factory settings,
or even cleared so that the transmitter will operate using sensor
characterization values.

ATTENTION The NI_FBUS Configurator application can be used to perform the

calibration procedures. The software application is not a calibrated
measurement source. It is a digital diagnostic tool that provides
verification of device parameter values.

Calibration Process In general, calibration procedures follow this process:

1. Prepare the transmitter
2. Write the appropriate parameters
3. Write to CAL_CMD.
4. The results of the calibration procedure are read from the
CAL_SOURCE and CAL_STATUS block parameters.

The calibration parameter values and calibration commands are written to

and read from the transmitter using a fieldbus configuration application,
(such as the NI_FBUS Configurator).

See Table #

Two-point calibration - Calibrates the transmitter range 72

using the two-point procedure. This procedure is also used
to calibrate the transmitter to operate at a range that is
smaller than its full range (Turndown calibration).

Restore to factory calibration - Sets the transmitter to 73

operate using the calibration values set at the factory. (The
factory calibration is stored in non-volatile memory in the
transmitter.)

Clear calibration - (Formerly called “Corrects Reset”) 74

Resets calibration and allows transmitter to operate using
characterization constants only.

Calibrate zero - (Formerly called “Input Zero”) Calibrates 75

the sensor to correct the input measurement due to fill fluid
and transmitter position effects once the transmitter is
installed and operating under process conditions.

Local zero correction - Calibrates zero point of the sensor 76

using the pushbuttons on the local meter. Performs the
same function as calibrate zero procedure.

Two-Point Calibration The ST 3000 FF Transmitter has two-point calibration. The calibration
is used to correct for any sensor accuracy drift over time. Two-point
calibration means you calibrate at two points in the calibration range (the
lower and upper trim points) and then all points within that range adjust
to that calibration.

Determine Lower and The two trim points are not fixed values, therefore you may choose the
Upper Trim Points trim point values which calibrate the transmitter.
· The lower trim point can be zero or a user-selected value for the
lower range value.
· The upper trim point can be a user-selected value for the upper range
value.

10.3 Calibration Continued

Clear Calibration to You can erase incorrect calibration data by clearing (or resetting) the
Characterization data to default values. The default values return the transmitter
Values (Also called calibration to the original factory “characterization” values.
Corrects Reset) Characterization calculates a mathematical model of the performance of
the transmitter’s sensors and then stores that data in the transmitter’s
memory. Note that this is not the “factory calibration” which is done at
the end of the process against the ordered range.

While clearing the calibration will return the transmitter to a close

approximation of the previous calibration using its stored
characterization data, the accuracy of the “reset” transmitter will be
lower than the specified factory calibrated accuracy. The calibration is
not exact since the transmitter mounting angle may be different than the
factory mounting angle. This means that the transmitter is calculating its
output based on the characterization equation alone without any
compensation for the small residual errors of zero offset and span
correction.

Example A typical zero offset correction is less than 0.1 inH2O for a 400 inH2O
range and a typical span correction is less than 0.2% regardless of the
range (down to the point where specification turndown begins). The
typical performance of a 400 inH2O transmitter after clearing calibration
(or a “Corrects Reset” as it is often called) can be expressed as:
æ 0.1 inH 2 O ö

Accuracy = 0.2% + è Span inH 2 Oø

By correcting the zero input, the typical performance will be 0.2% or

better.

For other transmitter ranges, the initial zero offset will be scaled by the
ratio of the Upper Range Limit (URL) to 400 inH2O at 39.2°F (4°C).
Thus, for a 100 psi range, the initial zero offset can be expressed by:
2768inH 2 O
0.1inH 2 O · = 0.7inH2 O or 0.025psi
400inH 2 O

Note that these are typical values and they may vary. However, our
patented characterization method includes several techniques that help to
ensure that this level of performance can be achieved.

10.3 Calibration Continued

Calibrate Zero This calibration procedure is performed after the transmitter is mounted
and installed in a process control system. Also called “Input Zero”.

Background Bench calibration is performed with the device removed from the
process and calibrated using reference pressure conditions. Often, when
the device is mounted and connected to the process, the input
measurement due to fill fluid and position effects cause the measurement
to shift. This calibration provides a means of correcting for these effects
without changing the calibration.

Correct Zero Use the procedure in Table 74 when calibrating the sensor to correct the
Calibration Procedure input measurement due to fill fluid and transmitter position effects.
NOTE 1: This procedure is not used for calibrating AP transmitters,
since it is nearly impossible to measure a true “zero” pressure.
NOTE 2: This procedure can be performed using the local meter. See
Table 75 for local zero correction procedure.

Table 75 Correct Zero Sensor Calibration Procedure

Step Action

1 Set the differential pressure input to zero by connecting a tube

between the input connections in the high pressure (HP) and the low
pressure (LP) heads.

2 Using a fieldbus configuration application as the operator interface to

device, set the Transducer block MODE_BLK parameter to O/S (Out
of Service)

3 Write CAL_ZERO (3) to parameter CAL_CMD to calibrate zero.

See Table 70, Calibration Parameters.
The device will use the average of the last 10 pressure samples to
perform the correction.

4 If calibration was successful:

CAL_STATUS = Success (1)
CAL_SOURCE = User (2), Proceed to next step.
If calibration failed:
CAL_STATUS = a value other than Success (1).

About this section this section contains information to guide you in identifying device
faults and suggested actions to correct them. The approach to
troubleshooting is geared toward determining the cause of the fault
through definition of the symptoms (such as device not visible on
network or not able to write values to parameters).
The information is organized the following way:
· Device Troubleshooting tables list some of the more commonly
encountered faults and suggested things to check in order to find out
where the problem is and correct it.
· Transmitter status tables define some of the conditions that cause
critical or non-critical faults in the transmitter. Critical and non-
critical faults are described and suggestions are given on where to
find further information.
· Device Diagnostics briefly explains about some of the background
diagnostics that are active in the device during normal operation.
Device parameters are described, which provide information about
hardware and software status within the device.
· Block Configuration Errors summarize conditions within the
device that may be caused by configuration errors and suggestions
on where to look to correct the errors.
· Simulation Mode tells you how to set up the transmitter to generate
a user-defined simulated input. This feature is useful in debugging
the system when the process is not running.

7/00 ST 3000 FF - Installation and Device Reference Guide 175

11.2 Overview

Device Status and ST 3000 transmitter is constantly running internal background

Faults diagnostics to monitor the functions and status of device operation.
When errors and faults are detected, they are reported in the status bits of
certain block parameters, (for example, BLOCK_ERR or
ERROR_DETAIL). Other parameters can be viewed which show a
status description and/or a value, which may help to identify a fault.

Device status and operational faults are identified by viewing key

parameter values or status and then interpreting their meaning using the
tables in this section.

ATTENTION Additional diagnostics may be available through supervisory and control

applications that monitor and control fieldbus networks. These
diagnostics and messages are dependent upon the capabilities of the
application and control system you are using.

Troubleshooting with The diagnostic messages generated by the ST 3000 FF transmitter and
the NI-FBUS block parameters can be accessed and evaluated using the NI-FBUS
Configuration Tool
Configurator. Troubleshooting of some transmitter faults and corrective
actions also can be performed using the configurator.

Diagnostics categories and could cause the following results:
1. Non-Critical Fault ¾ Transmitter continues to calculate PV output.
2. Critical Fault ¾ Transmitter drives PV output to failsafe state.
3. Block Configuration Errors ¾ Incorrect parameter values may
cause the transmitter to generate a fault, (for example, BLOCK_ERR
or MODE_BLK = OS.
A description of each condition in each category is given in the
following tables. The condition is described, a probable cause is stated
and a recommended corrective action is given for each fault.

11.7 Device Diagnostics

ST 3000 FF Memory The ST 3000 FF contains a number of areas of memory. An EEPROM

provides a non-volatile memory area for static and non-volatile
parameter values. The transmitter also contains areas of RAM and
ROM.

Background Block objects (Resource, Transducer and Function blocks), the

Diagnostics communications stack and other device objects each have a designated
area of memory where their database resides. Diagnostic routines are
performed in the background during device operation which check the
integrity of these individual databases. When a failure is detected, a status
bit is set in the BLOCK_ERR parameter in the appropriate block object.

Diagnostic checks are performed continuously on the device functional

databases of the transmitter application shown in Table 84.

ERROR_DETAIL ERROR_DETAIL parameter in the resource block contains data that

parameter describes the cause of any device-critical error. This category of error
will cause the resource block to remain in O/S actual mode regardless of
its target mode. This in turn causes all other blocks to remain in O/S
actual mode.

ERROR_DETAIL is an array of three unsigned integers, each 16 bits in

size. The three sub-elements are generally defined as follows:
1 - Error Type
2 - Location
3 - Sub-type

ERROR_DETAIL Table 86 lists the enumerated values for the Error Type element only.
Enumeration The Location and Sub-type elements have no significant meaning for
users.

11.8 Block Configuration Errors

Configuration Errors Block configuration errors prevent a device block from leaving O/S
mode. The BLOCK_ERR parameter (bit 1) shows whether a block
configuration error is present. Table 87 summarizes the conditions that
may be the result of block configuration errors, which in turn cause a
device fault. Follow the recommended actions to correct these errors.

11.9 Clearing Block Configuration Errors

Clearing Block Tables 88 and 89 list the parameters in the AI and PID blocks that can
Configuration Errors cause the status bit of Block Configuration Error to be set in their
respective BLOCK_ERR parameters. The tables also provide the initial
values and the valid range for the parameters.

NOTE: Block configuration errors can only be cleared if the function

block is being executed (running). One way of determining
block execution is by doing a series of two or three reads of the
BLOCK_TEST parameter and confirming that the first byte of
the parameter is incrementing. This will work if the execute
rate is fast relative to the speed of reading BLOCK_TEST. A
very slowly executing block may not appear to execute
because block parameters are updated only when the block
executes.

Classes Hazardous (classified) locations, in both the United States and Canada,
are categorized into one of these three classes.

Class Description of Hazardous Location

I Presence of flammable gases or vapors may be present in

quantities sufficient to produce explosive or ignitable mixtures.

II Presence of combustible dusts, powders or grains.

III Presence of easily ignitable fibers or flyings.

Divisions The classes listed above are further categorized based upon the level of
risk present.

Division Description of Risk

1 Locations in which hazardous concentrations of flammable gases

or vapors, or combustible dust in suspension are continuously,
intermittently or periodically present under normal operating
conditions.

2 Locations in which flammable gases or vapors are present, but

normally confined within closed containers or systems from which
they can escape only under abnormal or fault conditions.
Combustible dusts are not normally in suspension nor likely to be
thrown into suspension.

Examples Given the criteria above, the following examples are made:
A Class III, Division 1 location is a location in which easily ignitable
fibers or material processing combustible flyings are
handled, manufactured or used.
A Class III, Division 2 location is a location in which easily ignitable
fibers are stored or handled.

Groups Flammable gases, vapors and ignitable dusts, fibers and flyings are
classified into groups according to the energy required to ignite the most
easily-ignitable mixture within air. Group classifications are as follows:

Class I Description of Atmosphere

Group
A Atmospheres containing acetylene.

B Atmospheres containing hydrogen, fuel and combustible process

gases containing more than 30 percent hydrogen by volume, or
gases or vapors of equivalent hazard.

C Atmospheres such as ethyl ether, ethylene, or gasses or vapors

of equivalent hazard.

D Atmospheres such as acetone, ammonia, benzene, butane,

cyclopropane, ethanol, gasoline, hexane, methanol, methane,
natural gas, naphtha, propane or gases or vapors of equivalent
hazard.
Class II Description
Group
E Atmospheres containing combustible metal dusts including
aluminum, magnesium, and their commercial alloys, and other
metals of similarly hazardous characteristics.

F Atmospheres containing combustible carbonaceous dusts

including carbon black, charcoal, coal or other dusts that have
been sensitized by other materials so that they present an
explosion hazard.

G Atmospheres containing combustible dusts not included in Group

E or F, including flour wood, grain, and other dusts of similarly
hazardous characteristics.

Entity Concept Under entity requirements, the concept allows interconnection of

intrinsically safe apparatus to associated apparatus, not specifically
examined in such combination. The criteria for interconnection is that the
voltage (Vmax ) and current (Imax ), which intrinsically safe apparatus
can receive and remain intrinsically safe, considering faults, must be
equal to or greater than the voltage (Voc or Vt ) and current (Isc or It )
levels which can be delivered by the associated apparatus, considering
faults and applicable factors. In addition, the maximum unprotected
capacitance (Ci ) and inductance (Li ) of the intrinsically safe apparatus,
including interconnecting wiring, must be less than or equal to the
capacitance (Ca ) and inductance (La ) which can be safely connected to
the associated apparatus. If these criteria are met, then the combination
may be connected and remain intrinsically safe. Both FMRC and CSA
define the entity parameters in Tables A-1 and A-2.

A.2 International Electrotechnical Commission (IEC)
Classification of Hazardous Locations

About IEC The IEC has established a number of recommendations applying to the
construction of explosion protected electrical apparatus identified.
These recommendations are found within IEC 79-0 through
79-15 and 79-28.

For all EC countries as well as various neighboring countries

(CENELEC member states), the European Standards EN 50 014 to EN
50 020 and EN 50 039 apply for the construction of explosion protected
electrical apparatus. They were established on the basis of the IEC.
However these recommendations are much more detailed by
comparison.

Zones Within IEC7-10, hazardous locations are defined into one of these three
zones.

ZONE Description of Hazardous Location

0 Explosive gas atmosphere is present continuously, or is present

for long periods.

1 Explosive gas atmosphere is likely to occur in normal operation.

2 Explosive gas atmosphere is not likely to occur in normal

operation and, if it does occur, it will exist for a short period only.

IEC Groups Flammable gases, vapors and mists are further classified into groups
according to the energy required to ignite the most easily-ignitable
mixture within air. Apparatus is grouped according to the atmospheres
it may be used within as follows:

Group Description of Atmosphere

IIC Atmospheres containing acetylene, hydrogen, fuel and

combustible process gases or vapors of equivalent hazard.

IIB Atmospheres such as ethyl ether, ethylene, or gasses or

vapors of equivalent hazard.

IIA Atmospheres such as acetone, benzene, butane,

cyclopropane, ethanol, gasoline, hexane, methanol, methane,
natural gas, naphtha, propane or gases or vapors of equivalent
hazard.

A.3 Enclosure Ratings

NEMA and IEC The NEMA (National Electrical Manufacturer’s Association) enclosure
Recognition classifications are recognized in the US. The IEC Publication 529
Classifications are recognized throughout Europe and those parts of the
world that use the IEC standards as a basis for product certifications.
The following paragraphs provide a discussion of the Comparison
Between NEMA Enclosure Type Numbers and IEC Enclosure
Classification Designations.

IEC Classifications IEC Publication 529, Classification of Degrees of Protection Provided

by Enclosures, provides a system for specifying the enclosures of
electrical equipment on the basis of the degree of protection provided by
the enclosure. IEC 529 does not specify degrees of protection against
mechanical damage of equipment, risk of explosion, or conditions such
as moisture (produced for example by condensation), corrosive vapors,
fungus, or vermin.

NEMA Standards NEMA Standards Publication 250, Enclosures for Electrical Equipment
(1000 Volts Maximum), does test for environmental conditions such as
corrosion, rust, icing, oil, and coolants. For this reason, and because the
tests and evaluations for other characteristics are not identical, the IEC
enclosure classification designations cannot be exactly equated with
NEMA enclosure type numbers.

IEC Designations Basically, the IEC designation consists of the letters IP followed by two
numerals. The first characteristic numeral indicates the degree of
protection provided by the enclosure with respect to persons and solid
foreign objects entering the enclosure. The second characteristic
numeral indicates the degree of protection provided by the enclosure
with respect to the harmful ingress of water.

IEC Designations, Table A-6 provides an approximate conversion from NEMA enclosure
continued type numbers to IEC enclosure classification designations. The NEMA
types meet or exceed the test requirements for the associated IEC
classifications; for this reason the Table cannot be used to convert
from IEC classifications to NEMA types.

 Appendix C – Freeze Protection of Transmitters
C.1 Possible Solutions/Methods

Problem
When water is present in the process fluid and ambient temperatures can
fall below the freezing point (32°F/0°C), pressure transmitters and their
piping require freeze protection. Transmitters may also require continuous
heating, if the process fluid is tar, wax, or other medium that will solidify
at normal ambient. However, uncontrolled steam or electric heating, in
addition to wasting energy, can cause errors and accidentally destroy the
transmitter.

Solution
These two basic solutions are possible:
• Eliminate the need for heating the transmitter by keeping the freezable
process fluid out of direct contact with transmitter.
• Control the steam or electric heat to prevent overheating on warm days
while protecting against freeze-ups under the coldest conditions.
The other paragraphs in this section review a number of methods for
implementing both solutions.

Sealing liquid method

The simplest and least costly method is to use a sealing liquid in the
transmitter meter body and its impulse piping to the process. The small
contact (interface) area between the sealing liquid and the process fluid
reduces the mixing of the two fluids.

You should select a sealing liquid that has a greater specific gravity than
the process fluid to inhibit mixing. It also must have freezing and boiling
temperatures compatible with the range of temperatures existing at the
site, including the heated interface.

WARNING
WARNING — The user must verify the compatibility of any sealing
liquid with their process fluid.

A reliable sealing liquid is a 50/50 percent (by volume) solution of

ethylene-glycol and water. This solution has a specific gravity of 1.070 at
60°F (15°C), a freezing temperature of –34°F (–36°C), and a boiling
temperature of +225°F (+106°C) at atmospheric pressure. Conventional
antifreeze liquids for automobile coolant systems such as Prestone and

Sealing liquid method, continued

Zerex are solutions of ethylene-glycol with some rust inhibitors and
possibly leak sealants added; they may be used in place of pure ethylene-
glycol.

Another sealing liquid, used in many chemical plants, is dibutylphalate an

oily-type liquid with a specific gravity of 1.045 at 70°F (21°C). It has a
boiling point 645°F (340°C) and does not freeze so it can be used down to
about –20°F (–30°C).

Figures C-1 and C-2 show typical piping installations for this method. The
process fluid must be heated above its freezing point. This is frequently
done by lagging in (insulating) the connecting nipple, shut-off valve and
“T” connector with the process piping. Where the process piping itself
requires heating, a steam or electric trace is run around their components
with consideration given to the boiling point of the sealing liquid.

The installation should be checked every 6 to 12 months to verify that the

sealing liquid is at its required specific gravity.

Purging
Purging air or water purges are commonly used to prevent viscous
materials from clogging the impulse lines to pressure, level, or flow
transmitters. The bubbler system, using a constant-air flow regulator, is
particularly common on open tank liquid level applications. No heating of
impulse lines or transmitter is required, but normal precautions are
required to keep water out of the air supply system.

Gas applications
We must not overlook the possibility of condensate freezing in impulse
lines to transmitters measuring gas flow or pressure. Although these
components could be heated similar to water and steam applications, the
simplest and best approach is to install transmitters so that they are self
draining. This means that the impulse lines are connected to the lowest

point in the transmitter meter body and the piping is sloped downward at
least one inch per foot. (Side-connected transmitters with vent-drains at a
lower point in the meter body must be regularly checked to assure
condensate removal.) If the transmitter is located below the process taps
(not recommended), piping must still run downward from the transmitter
to the drain point and then up to the process as shown in Figure C-3.
Steam or electric heating of the drain point will prevent pipe rupture due
to freezing.

Mechanical (diaphragm) seals

Diaphragm seals on the impulse lines provide the most expensive, yet
broadest application of all the methods. Similar in principle to the liquid
seals, diaphragm seals eliminate the possibility of seal liquid carry-over
into the process fluid. This eliminates the need for periodic maintenance
checks to assure full and equal liquid seal legs. Welded diaphragm seals
with special fills permit temperatures from –34° to 600°F (–36° to 315°C)
at the process interface which can therefore be steam or electrically heated
to assure viscosity of tars and similar high-freezing point fluids under the
coldest conditions.

(diaphragm) seals,
continued
You must be careful to specify large enough diaphragms to accommodate
expansion and contraction of the fill fluid under varying temperatures
without overextending the diaphragm into its stiff area. In general,
conventional diaphragm seals are satisfactory for pressure ranges above
approximately 75 psig with special large diameter elements required for
low pressure or differential pressure measurements.

You can lag (insulate) impulse lines and diaphragm seals with the process
piping, but this practice is only common with liquid level applications
involving highly viscous materials unsuitable for 1/2-inch impulse lines.
Use a tank-mounted flanged seal in such installations. Otherwise, it is
more desirable to keep the capillary lengths short, the transmitter
accessible for maintenance, and (for flow applications) the normal 3-valve
manifold assembly close to the transmitter for normal service checks.
Thus, the impulse lines, valving and diaphragm seals with 1/2-inch
connections would be electrically or steam traced, with high temperature
steam permitted without damage to the transmitter. See Figures C-4 and
C-5 for typical piping layouts.

Electric heating
Most transmitters will withstand higher temperatures at their process
interfaces (bodies) than at their electronics. Normally, it is impractical to
heat transmitter bodies above 225 to 250°F (107 to 121°C) without radiant
and conducted heat exceeding the rating at the electronics (normally
200°F/93°C). Prefabricated insulated enclosures with integral heating
coils and thermostats set at 200°F (93°C) can assure viscosity of fluids
which freeze below 180°F (82°C) while assuring safe transmitter
operation. For water or similar lower-temperature mediums, the control
can be set at 50°F (10°C) to save energy and call for heat only when
temperature and wind conditions require.

Systems can be engineered for uncontrolled, continuous electric heating to

prevent water freezing at 0°F (–18°C) and 20 mph wind velocity, while
not exceeding 225°F (107°C) at the transmitter body at 90°F (32°C)
ambient and zero wind velocity. The operating costs in energy for these
systems usually exceed the high initial cost of the thermostat systems.
Never attempt to maintain freeze points above 100°F (38°C) without
thermostat controls since the Btu required to prevent freezing will
normally exceed the body temperature rating under opposite extremes.

Electric heating,
continued
Although systems are available with hollow bolts replacing the normal
transmitter body bolts and containing electrical heating elements and
thermostats, certain precautions are required with such arrangements.
Some transmitter meter body bolts are too small to accept the available
thermostats. Also thermostat settings should not approach the body
temperature limit because the heat gradient across the meter body can be
such that limits are exceeded adjacent to the heating elements even when
the thermostat setting is lower.

Electrical heating systems are available in explosionproof ratings for Class

I, Group D, Division I and II installations.

The possibility of electric supply failure must be considered. For this

reason, we recommend using alarm devices with manual acknowledgment
and reset.

Steam heating
Steam heating is perhaps the most common, yet potentially the most
damaging method of protecting transmitters from freeze-ups. Since steam
is generated for use in the overall process operation, it is considered an
available by-product. The most important point to remember when steam
heating transmitter meter bodies is the temperature of the steam that will
be used and its pressure. We recommend that you review the next
paragraph Superheated steam considerations to get a better understanding
of the temperature problem with steam heating. In brief, do not assume
that 30 psig steam is 274°F (134°C) and cannot damage a transmitter rated
for 250°F (121°C). With steam heating, as with electrical, you should use
insulated transmitter body housing, impulse piping and valves.

piping down to the trap. You should also use conventional steam traps
with lower pressure desuperheated steam which cannot overheat the
transmitter under warm-day conditions. If the heating pipes are not
carefully installed to eliminate low spots and trapped condensate in the
piping, they could freeze at low temperatures.

All steam traps require a periodic maintenance program. Dirt, scale, and
water softeners will cause traps to stick or jam which result in their either
blowing steam continuously or not blowing steam, allowing condensate
freeze-up in cold weather. When steam traps are used for cold-weather
freeze protection of water lines, a thermostat controlled steam supply
valve, which will shut off the steam at ambient temperatures higher than
50°F (10°C), will save steam and prevent overheating.

A more general solution is offered by a specialized type of trap that

throttles condensate flow based on its temperature. This backs up hot
water in the radiator within the insulated transmitter enclosure, assuring
temperatures no higher than the saturated steam at the reduced pressure.
Models are available to set the condensate temperature from about 70° to
200°F (21° to 93°C). They must be located within 6 to 12 inches (15 to 30
cm) of the transmitter body and , like all steam traps, they also require
periodic maintenance. The engineering of this type system is more
complex than electric systems since the amount of heat loss upstream of
the CTV valve under varying conditions will determine the location of the
steam/water interface. It could occur within the heater coil or further up
the steam line, thus affecting the heating efficiency within the insulated
enclosure. Therefore, steam control of materials which freeze or become
too viscous above 100°F (38°C) should probably not be attempted without
some experimenting with the specific piping layout used.

Uncontrolled steam heating, even with the best pressure regulation and
desuperheating of steam, should not be used to maintain transmitter
temperatures above 100°F (38°C), since this type of fixed Btu input must
either over or under-heat under normal ambient swings.

As with electric heating, there are many types of commercial steam

heating units available such as radiant heaters, hollow meter body studs or
just tubing lagged to the impulse piping and transmitter body. The same
precaution applies to the use of hollow studs as on the electrical versions.

Superheated steam
considerations
We must remember that the temperature of steam is 212°F (100°C) only at
the normal atmospheric pressure of about 14.7 pounds per square inch
absolute (psia). If the pressure of steam is increased above 14.7 psia, the
temperature of the steam is also increased. For example, if we have steam
at 30 pounds per square inch gage (psig), the steam temperature is 274°F
(134°C).

C.1 Possible Solutions/Methods, Continued

Superheated steam
considerations,
continued
On industrial flow and pressure measurement applications, we may be
required to use steam to heat the impulse piping to the flow or pressure
transmitter, as well as the transmitter itself. For these applications, we
must verify the temperature of the heating steam used. As an example,
assume that steam at 100 psig saturated (338°F/170°C) is to be reduced to
30 psig pressure for the heating system. Too frequently, it is assumed that
this pressure reduction will result in steam at 274°F (134°C), the
temperature of saturated steam at 30 psig. Wrong! A reduction of the
steam pressure will not appreciably decrease the initial steam temperature.

In our example, we were talking about saturated steam in the main header
from the boiler. But modern industrial boilers cannot afford to let waste
heat go up the stack. After reaching the boiling point in the drum, the
steam flows through a series of pipes in the second pass of the flue gas
exit, extracting additional heat energy and being raised to a temperature
higher than the saturation temperature at the same pressure. This is
superheat and, depending on boiler design, it may amount to 50 to 300°F
(10 to 149°C) above the saturated steam temperature. It also permits
packing more heat energy in a given size pipe for transmission from the
process. Thus, in the typical application, the problem of steam heating is
compounded by the additional superheat in the main header.

Specifically, when steam is reduced in pressure, it retains about the same

latent heat or the same Btu’s/pound at the reduced pressure. Therefore, in
our example, steam at 100 psig and 338°F (170°C) when reduced to 30
psig steam will have a temperature of 306°F (152°C) or a loss of only
32°F (18°C).

This steam temperature can only be reduced by using a desuperheater.

This device mixes cold water with the superheated steam to reduce its
temperature by removing Btu’s per pound of water (steam). It is also
possible to use temperature controlled steam traps, which actually allow
the steam to condense to water and therefore reduce its temperature to a
pre-set value.

ST 3000 FF Transmitter
With Foundationä Fieldbus Option
Installation & Device Reference Guide
34-ST-25-15B

Overview Two new models have been added to the family of ST3000 Smart
Transmitters:

Gauge Pressure Model STG19L

Gauge Pressure Model STG99L.

Each of these has an Upper Range Limit (URL) of 10000 psi (690 bar),
which is significantly higher than previously available models. Also,
each of these new models has significantly higher ratings for Maximum
Working Pressure (10000 psi, or 690 bar) and Overpressure (15000 psi,
or 1034 bar). The burst pressure is rated at 26000 psi (1793 bar).

Except for the higher operating range, each of these two new models
includes physical and functional features similar to those of closely
related family members (STG1xL and STG9xL). With the exceptions
noted in this addendum, all parts of User Manual 34-ST-25-15B apply to
these new models.

Because of the similarities between new and existing models, these new
devices can be used as direct replacements in circumstances that require
higher pressure capabilities.

Details of pressure ranges for these new models are specified in

“Additions and Changes to the Manual”, below.

Overview Replacement Meterbody and Heads

The ST 3000 Pressure Transmitter, Models:

• STD110, STD120, STD125, STD130, and STD170
• STD924 and STD930 with optional Tantalum or Monel diaphragm
is now being shipped with newly designed meter body and process heads. If a
replacement meter body is needed, it should be ordered from the Model Number stated
on the meter body nameplate. This number includes the letter “S” after the model
number; for example, STD110S-xxx.
This new transmitter is functionally identical to previous models in that the working
ranges (Lower Range Limit to Upper Range Limit) and intended applications have not
changed. However, the specifications for the maximum Pressure Rating and for the
Overpressure Rating have been enhanced in all models except the draft range
transmitter. A summary of specifications is given in Table 7.
The new versions, which will continue as Models STD110, STD120, STD125,
STD130, STD170, STD924, and STD930, differ only in the physical size and form of
the meter body, process head, and associated components.
With exceptions noted in this addendum, information given in User’s Manual
34-ST-25-15B applies also to this newer design.
Installation, operation, maintenance, calibration, and troubleshooting tasks remain
virtually the same as for the previous version. Differences appear primarily in torque
specifications when replacing meter bodies, and in part numbering and part
recognition when replacing components or assemblies.
Related This addendum provides details for parts replacement that span a variety of
Publications applications of the Models STD110, STD120, STD125, STD130, STD170, STD924,
and STD930.

Overview ATEX Directive 94/6/EC

The ATEX Directive 94/6/EC is a European CE Mark directive concerning products

that are designed for use in potentially explosive environments. This “New
Approach” directive is based on, and is an expansion of, European Norms (EN,
CENELEC standards).
On June 30, 2003, the ATEX (ATmospheres EXplosibles) directive will replace
directives currently in effect, and from that time, only products with the ATEX
certification and with ATEX labeling will be approved for free movement in the 19
EU (European Union) and EFTA (European Free Trade Association) countries. As
defined in the directive, “free movement” refers to:

− placing a product on the market, and/or

− placing a product into service.

The ATEX Directive 94/6/EC is a living (set of) document(s), subject to further
change and refinement, whose details are beyond the scope of this addendum.
Further information can be obtained in the Official Journal of the European
Communities No L100/1, and in related publications such as Guidelines on the
Application of Directive 94/9/EC. Both of these items are available at:
http://europa.eu.int/comm/enterprise/atex/index.htm
Products that have been previously certified under the EN and CENELEC European
Norms, and which comply fully with all standards in the New Approach directive
have, by application, received certification under ATEX Directive 94/6/EC.
The Honeywell ST3000 Smart Pressure Transmitter is now ATEX certified, and all
units manufactured currently and in the future will include labeling that includes all
markings required under the ATEX directive.
Inclusions To ensure that all required information will be available to the user, the following
items are include with this Addendum for reference:
1. Declaration of Conformity – ATEX CE0344 (Honeywell document number
51452504 Revision B).
2. Certificate of Manufacturer – Ex II 3 G, EEx nA IIC ATEX CE (Honeywell
document number 51452622 Revision B).
