Section 1 —Smart Field Communicator STS103 Overview

1.1 Introduction

Function

Smart Field Instruments (SFIs)

ATTENTION

The hand-held Smart Field Communicator(SFC), Model STS103 is a battery-powered device which establishes two-way communications

between Honeywell’s Smart Field Instruments (SFIs) and an operator over the existing SFI signal lines. The operator can send data to and receive data from the SFI’s microprocessor, through the STS103, when connected to the SFI’s signal lines at any accessible location from the control room to the Smart Field Instrument.

There are many current SFIs with which the STS103 communicates. The STS103 is designed for expansion and will be used with other new SFIs as they become available. The current Honeywell smart field instruments with which the STS103 may be used are listed below.

• Smart Pressure Transmitter ST 3000,

• Smart Temperature Transmitter STT 3000,

• Magnetic Mass Flowmeter MagneW 3000,

• Smart Coriolis Mass Flowmeter SCM 3000,

• Smart Gas Chromatograph SGC 3000, and

• Smart Multivariable Transmitter SMV 3000.

The specific instructions for using the SFC with SCM 3000, and SGC 3000 are contained in User’s Manual for that specific instrument.

Operation

You can use the STS103 to

• Select the Communications Mode – Command the SFI to transmit its

output signal in either an Analog (4-20 mA) mode or in the Digital Communications (DE) mode.

• Configure – Enter the desired operating parameters (For example:

LRV, URV, Damping, Failsafe Mode, Configuration Parameters) into the Smart Field Instrument.

• Diagnose – Access the SFI self-diagnostic capabilities to troubleshoot

suspected operation or communication problems.

• Calibrate – The SFC provides a simplified procedure for calibrating

Smart Field Instruments, thus maintaining excellent accuracy with significantly reduced maintenance requirements.

• Display – Readout all the configured operating parameters from the

SFI as well as other data such as PROM Serial Number, Device ID, Scratch pad memory, Sensor Temperature, Input values in selected Engineering Units, and others.

Battery pack location

The battery pack is located behind the LCD display and is accessed through a back panel. Two hex screws need to be removed to access the battery pack. Figure 1-4 shows the location of the battery pack and how it fits into the STS103.

Figure 1-4 STS103 Battery Pack

20722

Charging the batteries

STS103 charging terminal

Self-diagnostics

The battery pack is charged by plugging the battery charger into an outlet and inserting the lead into the charging terminal of the STS103. The battery pack takes a minimum of 10 hours to charge and the STS103 may be used continuously for up to 24 hours before the battery pack needs recharging. A colon (:) will be appear in the middle of the top line on the LCD display when the battery pack needs charging.

The battery pack is charged through a battery charger that plugs into the charging terminal. The charger inputs 110 or 220 Vac 50/60 Hz and outputs 7 Vdc 180 mA to the NiCd battery pack. The connector of the battery charger is inserted into the charging terminal on left side of the STS103 by the ON/OFF switch.

When the STS103 is turned on, it automatically runs diagnostics on its functions. Upon successful completion of the diagnostics, the message,

“PUT LOOP IN MAN” (analog communications) or “DE-XMTR PRESS ID” (digital communications)

appears. If an error occurs, the message,

“CRITICAL STATUS” appears.

Refer to Section 3 for a description of the STS103 errors or the individual device sections for device specific error messages.

1.3 Connections

Connecting the STS103 to junction boxes and IS panels

The STS103 connects to SFIs, IS panels, and junction boxes through a pair of wires with alligator clips on the ends. The STS103 communications terminal end of the wires has a stereo phone jack connection that is inserted into the communications terminal. The other end of the wires are clipped onto terminals in the junction box or IS barrier panel, or directly to the transmitter. The red SFC lead connects to the junction box or SFI positive terminal, the black lead to the negative terminal.

Figure 1-5 shows the STS103 connected to a junction box and an IS barrier panel.

The STS103 connects directly to the positive and negative terminals on the SFI. The STS103 can connect to only one SFI at a time.

REFER TO THE INDIVIDUAL DEVICE SECTIONS IN THIS MANUAL for instructions on how to wire the STS103 to your particular device (SFI).

4/99 STS103 Operating Guide 9

1.4 STS103/SFI Communication

How data is transferred

Types of communication

Sending and receiving data to and from an SFI is done over the

transmitter’s 4-20 mA wires. When the STS103 is connected to a transmitter and turned on, it automatically determines what type of transmitter it is communicating with. When data is sent to a transmitter, a request is sent to the transmitter and a response is sent back to the STS103. When the STS103 and SFI are communicating, the message “SFC Working...” is displayed on the STS103.

The message handling routines are transparent to you. The way the request and response messages are handled depend on whether the transmitter is an analog only model or an analog/digital model, and the mode configuration.

Analog communications uses half duplex communication (data can be sent in one direction at a time, to the transmitter or to the STS103) while the digital communication uses half duplex with or without broadcast (4 or 6 bytes). Table 1-3 describes the communication formats used.

Table 1-3 Communication Format Description

Format Description

Analog Communication Mode

DE READ

Digital (DE) Communication Mode

DE READ

SHH

HII

IFF

FTT

Analog communication uses a half-duplex , variable-length message with a wake-up pulse for on-demand requests and responses. While the messages travel back and forth, the

transmitter’s output varies between 4-20 mA, therefore, the control loop must be in manual so the data exchange does not interfere with the control loop.

Digital communication also uses a half-duplex , variablelength message with no wake-up pulse for on-demand requests and responses (not including data uploads). The data is piggybacked on the process variable data being sent on the control loop.

The broadcast 4-byte format is rarely used because no

database protection can be performed when used in the TDC 3000 system. This mode is only used when faster PV update rates are required. One byte is for transmitter status and configuration data; the other three are for process data.

The broadcast 6-byte format is used for uploading the transmitter’s database to the STS103’s hold memory. The bytes are similar to the 4-byte format, but it includes two additional bytes of transmitter database information.

1.4 STS103/SFI Communication, Continued

Analog data exchange

When the STS103 communicates with an analog transmitter, a 26 mA wake-up pulse is sent to the transmitter to put the device into the communication mode. The pulse also causes the current drawn by the device to drop to 4 mA. Data is then exchanged in an analog fashion (4-20 mA) between the STS103 and SFI. Figure 1-6 shows a typical analog data exchange using the STS103.

Digital data exchange

Data exchanges between the STS103 and digital devices are in ASCII. The exchange starts off with the STS103 requesting the transfer and the SFI then responds. Figure 1-7 shows a typical digital data exchange using the STS103 and Table 1-4 Describes the sequence of events.

4 The STS103 transmits a request and message during the next inter-

message gap.

5 The transmitter halts broadcasting process variable (PV) data when

the request is detected.

6 After receipt of a complete message, the transmitter returns to its

configured broadcast mode and processes a response message.

7 After completion of processing, the transmitter sends the response

message in half duplex protocol after the next PV data broadcast.

8 Upon completion of the data transfer, the transmitter returns to its

configured broadcast mode within 100 msec.

3.3 Diagnostics and SFC Messages

Introduction

OK Status

Critical status

The STS103 and the SFIs both run continuous self-diagnostics. This means that they are constantly testing the communications, the loop, and themselves.

Any time you want results of these diagnostics, press the STAT key. The SFC displays its report, in the form of messages, which identify

diagnostic conditions. Diagnostic conditions are broken down into three categories:

• an OK condition

• a critical condition

• a non-critical condition

An OK condition means no problem exists, and the display looks like this:

STATUS XXXX STATUS CHECK=OK

A critical condition means that the SFI is not functioning properly. When this occurs, the SFI goes into upscale burnout and maintains an output of

21.8 mA, or into downscale burnout and maintains an output of less than

3.9 mA. This message CRITICAL STATUS interrupts your operation and is followed by the message PRESS STATUS.

Non-critical status

Low battery voltage

After the PRESS STATUS message, you press the STAT key to find out what problem exists. You will receive one or more messages. Take

whatever corrective action necessary to solve the problem. Remember that the SFI will stay in upscale or down scale burnout until the condition is corrected. If the SFI sends more than one message, each message will be displayed in the order of importance for about 5 seconds. If you need to see them

again, press the STAT key again.

A non-critical condition means that although a problem exists, the SFI is still operating. When a non-critical condition occurs a “#” character appears on the right side of the display, along with whatever you’re displaying at the time.

This character means press the STAT key because some type of a problem exists. Again, one or more messages will appear on the display

for about five seconds each.

When the battery voltage becomes low, a colon “:” will appear in the middle of the display. It stays on the display until you either charge or replace the batteries.

Selecting configuration data for the digital communications mode

You determine how the Digital PV data is handled by configuring the DE configuration elements shown in Table 3-2.

Table 3-2 DE Configuration Elements

Element Selections And Definitions

Type of Transmitter This element selects the type of transmitter operation. The selections are:

• Single Range Working range PV (PVw) for STDC card or STI module.

• Single Range W/SV Working Range PV(PVw) with sensor temperature for STDC card or STI Module.

• Dual Range (STDC) Full range PV (PVt) and Working range PV (PVw) (For STDC only).

Message Format This element is the message format. The selections are:

• w/o DB (4 Byte) 4 Byte message format (PV or SV only), without

database information.

• W/DB (6 Byte) 6 Byte message format (PV or SV with database

information).

Failsafe Mode for

Digital Control System

This element is the Failsafe mode. You configure the flowmeter to tell the control system, via the ST/DC card, which failsafe mode to assume when the card detects a critical failure condition. A critical fault can be due to a critical status indication from the flowmeter or an extended loss of PV data.

The selections are:

• F/S=B/O Lo Burnout low (drives the PV value to the downscale limit).

• F/S=B/O Hi Burnout high (drives the PV value to the upscale limit).

• LKG Last known good PV value.

• F/S=FSO,B/O Lo Freeze slot output and burnout low (ST/DC card tells

the controller to hold the memory block output at the preset value and drives input to the controller downscale to trip alarms).

• F/S=FSO, B/O Hi Freeze slot output and burnout high (ST/DC card tells

the controller to hold the memory block output at the preset value and drives input to the controller upscale to trip alarms).

• F/S=LKG Freeze slot output and last known good PV (ST/DC

tells the controller to hold the memory block output at the present value and provides the last known good PV value as the input to the controller).

3.5 Using the Transmitter as a Current Source

Introduction

ATTENTION

One of the unique features of a Smart Field Instrument is its ability to be used as a constant current-source. This feature allows you to use it for calibrating other instruments in the loop such as recorders, controllers, and positioners.

As you know, the output of the SFI ranges from 4 to 20 milliamps where 4 mA = 0% output and 20 mA = 100% output. Using the STS103, you can tell the SFI to change its output to any value between 0 and 100% and maintain that output. Then you can use this output as a calibration input source to the other instruments in the loop.

Note that the current “output mode” overrides all other PV data from the SFI including the burnout data in the Digital Communications mode.

When you use the SFI as a current source, it no longer acts as a SFI. Make sure to clear this output mode when you are finished.

4.2 Wiring

Overview

Connecting the STS103 to junction boxes and IS panels

Establish communications with the ST 3000 by connecting the SFC leads

to the 4–20 mA line of the transmitter.

Your choices are either at a junction box somewhere along the 4–20 mA line, on the field side of the intrinsic safety barrier panel in the control room, or at the transmitter itself.

Following are examples for connecting to all these places. Use the one you need.

The STS103 connects to ST 3000 transmitters, IS Panels, and junction boxes through a pair of wires with alligator clips on the ends. The STS103 communications terminal end of the wires has a stereo phone jack connection that is inserted into the communications terminal. The other end of the wires are clipped onto terminals in the junction box or IS barrier panel, or directly to the transmitter. The red SFC lead connects to the junction box or SFI positive terminal, the black lead to the negative terminal.

Figure 4-1 shows the STS103 connected to a junction box or an IS barrier panel.

This loads the Digital Transmitter database to the SFC. The display indicates the percent of the database being loaded until it reaches 100%.

When setting-up or configuring a ST 3000, whether you are changing one element or a full database, you must copy all configuration data into the

transmitter’s non-volatile memory. This is the transmitter’s permanent memory. If the transmitter were to lose power, the values for the database will be saved here. The transmitter also contains a working memory that loses its contents if the power goes off; and when power is restored, the transmitter copies the contents of the non-volatile memory into the working memory.

There is a failsafe procedure. Thirty seconds after a value is changed, the transmitter automatically copies it into the non-volatile memory. But, if you change an element and power goes down before this runs, you will still lose the data in the working memory. Therefore, whenever you make any changes in the transmitter, always end your procedure as follows:

Adjusting the damping time

Damping time sets the unit of time for the damping constant. This constant establishes the upper limit of frequency response and the response time characteristics of the transmitter. This is used to reduce the electrical noise effect on the output signal.

Using the SFC, you can adjust the damping by selecting a value on the SFC and send that value to the transmitter.

• The minimum value is 0.0 seconds (no damping).

• The maximum value is 32.0 seconds.

Figure 4-3 is a graphic view of the key presses required to adjust the damping time value and also gives you the settings available.

You can also key–in a value using the numbered yellow keys but the value will default to the closest value listed.

Selecting the units in which to display values

Although the most common units for measuring pressure are inches of water or pounds per square inch, you may want it shown in another unit.

The SFC Model STS103 (Software Rev. 3.2 and up) can display the values for LRV, URV, SPAN, URL, and INPUT in one of thirteen pre-programmed units. These are:

• PSI Pounds per square inch

• KPa Kilopascals

• MPa Megapascals

• mBAR Millibar

• BAR Bar

• G/cm

• Kg/cm

Grams per square centimeter Kilograms per square centimeter

• inHg at 32F Inches of mercury at 32°F

• mmH2O at 4C Millimeters of water at 4°C

• mH2O at 4C Meters of water at 4°C

• inH2O at 39F Inches of water at 39.2°F *

• inH2O at 68F Inches of water at 68°F

• mmHg at 0C Millimeters of mercury at 0°C

ATTENTION

The Honeywell factory standard for the calibration of “inches of water” transmitters is to use inches of water referenced to a temperature of 39.2°F.

When a unit is changed, the SFC automatically performs a calculation for the new value and displays the new value in whichever unit you have selected.

Selecting configuration data for the digital (DE) communications mode

You determine how the Digital PV data is handled by configuring the DE configuration elements as shown in Table 4-3.

Table 4-3 The ST 3000 DE Configuration Elements

Element Selections And Definitions

Type of Transmitter This element selects the type of transmitter operation. The selections are:

• Single Range Working range PV (PVw) for STDC card or STI module.

• Single Range W/SV Working Range PV(PVw) with sensor temperature for STDC card or STI Module.

• Dual Range (STDC) Full range PV (PVt) and Working range PV (PVw) (For STDC only).

Message Format This element is the message format. The selections are:

• w/o DB (4 Byte) 4 Byte message format (PV or SV only), without database information.

• W/DB (6 Byte) 6 Byte message format (PV or SV with database information).

Failsafe Mode for

Digital Control System

This element is the Failsafe mode. You configure the transmitter to tell the control system, via the ST/DC card, which failsafe mode to assume when the card detects a critical failure condition. A critical fault can be due to a critical status indication from the transmitter or an extended loss of PV data.

The selections are:

• F/S=B/O Lo Burnout low (drives the PV value to the downscale limit).

• F/S=B/O Hi Burnout high (drives the PV value to the upscale limit).

• LKG Last known good PV value.

• F/S=FSO,B/O Lo Freeze slot output and burnout low (ST/DC card tells

the controller to hold the memory block output at the preset value and drives input to the controller downscale to trip alarms).

• F/S=FSO, B/O Hi Freeze slot output and burnout high (ST/DC card tells

the controller to hold the memory block output at the preset value and drives input to the controller upscale to trip alarms).

• F/S=LKG Freeze slot output and last known good PV (ST/DC

tells the controller to hold the memory block output at the present value and provides the last known good PV value as the input to the controller).

Setting the lower and upper range values of the transmitter using an applied pressure

On some applications there may be two unknown pressures (for example: liquid level) that represent a full and empty tank that you would want to use. The ST 3000 can set the lower and upper range values to these pressures. Follow the procedures given to set the LRV and URV using applied pressure. If you are working on a transmitter in a process, use the actual pressure from the process. If you are working on a set up with a pressure source, simulate the pressure.

Set the lower range value

4.5 Output Calibration

Introduction

To calibrate the output of an Analog transmitter, connect a precision volt– or ammeter at the appropriate connection point on your system or use the control room display to monitor the output signal.

If the 0 or 100% output is not correct, you can do a Digital to Analog Current Output Signal Calibration.

Do a DAC calibration

With this procedure you can calibrate the digital to analog current output zero and span.

Use the procedure in Table 4-7 to enter the Output mode, check the 0% and 100% output value and if necessary, do a digital to analog current output signal calibration.

4.7 Diagnostics and SFC Messages

Introduction

OK Status

Critical status

The ST 3000 and the STS103 both run continuous self-diagnostics. This means that they are constantly testing the communications, the loop, and themselves.

Any time you want results of these diagnostics, press the STAT key. The SFC displays its report, in the form of messages, which identify

diagnostic conditions. Diagnostic conditions are broken down into three categories:

• OK status

• critical status

• a non-critical condition

An OK condition means no problem exists, and the display looks like this:

STATUS (tag no.) STATUS CHECK=OK

A critical condition means that the transmitter is not functioning properly. When this occurs, the transmitter goes into upscale burnout and maintains an output of 21.8 mA, or into downscale burnout and maintains an output of less than 3.9 mA. The message CRITICAL STATUS interrupts your operation and is followed by the message PRESS STATUS.

Non-critical status

Low battery voltage

After the PRESS STATUS message, you press the STAT key to find out what problem exists. You will receive one or more messages. Take

whatever corrective action necessary to solve the problem. Remember that the transmitter will stay in upscale or down scale burnout until the condition is corrected. If the transmitter sends more than one message, each message will be displayed in the order of importance for about 5 seconds. If you need to

see them again, press the STAT key again.

A non-critical condition means that although a problem exists, the

transmitter is still operating. When a non-critical condition occurs a “#” character appears on the right side of the display, along with whatever you’re displaying at the time.

This character means press the STAT key because some type of a problem exists. Again, one or more messages will appear on the display

for about five seconds each.

When the battery voltage becomes low, a colon ”:” will appear in the middle of the display. It stays on the display until you either charge or replace the batteries.

5.2 Wiring

Overview

Connecting the STS103 to junction boxes and IS panels

Establish communications with the STT 3000 by connecting the SFC

leads to the 4–20 mA line of the Transmitter.

Your choices are either at a junction box somewhere along the 4–20 mA line, on the field side of the intrinsic safety barrier panel in the control room, or at the transmitter itself.

Following are examples for connecting to all these places. Use the one you need.

The STS103 connects to STT 3000 transmitters, IS Panels, and junction boxes through a pair of wires with alligator clips on the ends. The STS103 communications terminal end of the wires has a stereo phone jack connection that is inserted into the communications terminal. The other end of the wires are clipped onto terminals in the junction box or IS barrier panel, or directly to the transmitter. The red SFC lead connects to the junction box or SFI positive terminal, the black lead to the negative terminal.

Figure 5-1 shows the STS103 connected to a junction box or an IS barrier panel.

Setting the units in which to display values

Upon power up, the SFC always displays units in degrees C for any STT 3000 transmitter. You may want temperature shown in another unit.

The SFC can display the values for LRV, URV, SPAN, URL, LRL, +Hi/Lo PV, and INPUT in one of several pre-programmed units. These are:

• °F degrees Fahrenheit

• °C degrees Celsius

• °R degrees Rankine

• °K degrees Kelvin

In the case of non-linear inputs (Configuration selection O/P=NON_LINEAR - See Section 5.4)

• MV Millivolts

• Ω Ohms

When a unit is changed, the SFC automatically performs a calculation for the new value and displays the new value in whichever unit you have selected.
