• T = Temperature

1.2.2 Functional Characteristics

The transmitter measures process temperature and outputs a signal proportional to the measured process variable (PV). Available output communication protocols include analog 4 to 20 mA and HART protocol.

An optional 3-button assembly is available to set up and m ak e adjustm ents to the transm itter. In addition, a Honeywell Multi-Communication MC Toolkit (MCT404) (not supplied with the transmitter) can facilitate setup and adjustment procedures in the case of HART.

1.3 STT750 SmartLine Transmitter NamePlate

The Transmitter nameplate mounted on the top of the Electronics Housing (see Figure 2) lists the model number, physical configuration, electronics options, accessories, certifications, and manufacturing specialties. Figure 3 is an example of a typical STT750 temperature Name plate. The model number format consists of a Key Number with several table selections.

Figure 3 –Typical STT750 Nameplate

You can readily identify the series and basic transmitter type from the key number. The letter in the third digit represents one of these basic transmitter types:

For a complete selection breakdown, refer to the appropriate Specification and Model Selection Guide provided as a separate docum ent.

1.4 Safety Certification Information

An “approvals” name plate is located on the bottom of the Electronics Assembly; see Figure 1 for exact location. The approvals name plate contains information and service marks that disclose the transmitter compliance information. Refer to Appendix A in the STT750 SmartLine Transmitters User’s Manual, document number 34-ST-25-13 for details.

1.5 Transmitter Adjustments

Span adjustments are possible in new generation STT750 SmartLine Temperature Transmitters by using the optional 3-button assembly located at the top of the Electronic Housing, see Optional 3-

Button Assembly on page 5. However, certain c ap ab il i ties are limited in th e fo l lo w ing configurat ion s :

• Without a display –Span setting only for a HART device.

• With a display – Complete transm itter configuration is possible for a HART device.

Revision 3.0 STT750 Series HART Option User’s Manual Page 3

For HART you can also use the Honeywell MC Toolkit or other third-party hand-held to make any adjustments to an STT750 SmartLine Temperature Transmitter. Alternately, certain adjustments can be made through the Experion or Universal Station, if the transmitter is digitally integrated with a Honeywell Experion or TPS system. .

1.6 Local Display Options

2 Communication Modes

2.1 Overview

The STT750 SmartLine Temperature Transmitter can be configured for operation with HART version 7 communication. This manual addresses the processes to configure and calibrate a transmitter for HART communication.

2.2 HART Mode Communication

When using MCToolkit (MCT404), but before connecting to a HART transmitter, verify that

the FDC application is used and not the MC Toolkit application.

• Transmitters with HART capability have features that vary among manufacturers and with the

characteristics of specific devices. The FDC software application executing on the MCT404 supports the HART Universal, Common Practice and Device Specific Commands which are implemented in the Honeywell transmitters.

As indicated in Figure 4, the output of a transmitter co nfig ured for HART protocol includes two primary modes:

Figure 4 – HART Point-to-Point and Multi-drop Value Scaling

• Point-to-Point Mode, in which one transmitter is connected via a two-conductor, 4-20 mA

current loop to one receiver.

• Multi-Drop Mode, in which several transmitte rs are co nnec ted through a two-conductor

network to a multiplexed receiver device.

Revision 3.0 STT750 Series HART Option User’s Manual Page 7

In point-to-point mode, the value of the primary Process Variable (PV) is represented by a 4-20 mA current loop, almost identical to that of a tr ansm itter operating in analog m ode. You can also have one device in analog output mode when you are configured as multi-drop. In this case, however, the analog signal is modulated by Frequency Shift Keying (FSK), using frequencies and current amplitude that do not affect analog sensing at the receiver. The accuracy of the analog level must be precisely controlled for accurate sensing. HART communication will not bump process variables.

In multi-drop mode, up to 16 transmitters in HART 5 (addresses 0-15) and up to 64 transmitters in HART6/7 (addresses 0-63) can exist on the two-conductor network.

Startup tasks and procedures

3 Configuration Tools and Interfaces

3.1 Overview

This section describes the tools and interfaces involved in configuring a new STT750 SmartLine Temperature Transmitter for HART communication operation. The information in this section also applies to adjusting the configuration of a transmitter that has been in operation and updating one that is currently in operation.

3.2 Pre-requisites

The information and procedures in this manual are based on the assumption that personnel performing configuration and calibration tasks are fully qualified and knowledgeable in the use of the Honeywell MCT404. The name MC Toolkit (MCT404) are used interchangeably as MCT404 is the model name for the Honeywell MC Toolkit product. Furthermore, we assume that the reader is intimately familiar with the STT750 family of SmartLine Temperature Transmitters and thoroughly experienced in the type of process application targeted for transmitter deployment. Therefore, detailed procedures are supplied only in so far as necessary to ensure satisfactory completion of configuration tasks.

3.3 Application Design, Installation, Startup, and Oper a ti on

The STT750 SmartLine Temperature Transmitters User’s Manual, document number 34-ST-25-13, provides the details for application design, installation, and startup; see Table 3 for topics.

3.3.1 Organization

This information in this section is arranged in the following sequence:

• MC Toolkit participation in STT750 transmitter setup and configuration:

o Physical circuit connection s o Application components o Configuration for Analog and HART operation

• STT750 Transmitter

o Basic display o Health indications

o Ability to be configured and operate in a process system

Revision 3.0 STT750 Series HART Option User’s Manual Page 9

3.4 MC Toolkit Participation

Before using the MC Toolkit, be sure that you are aware of the potential consequences of each procedure, and that you use appropriate safeguards to avoid possible problems. For example, if the transmitter is an element in a control loop, the loop needs to be put in manual mode, and alarms and interlocks (i.e., trips) need to be disabled, as appropriate, before starting a procedure.

3.4.1 MC Toolkit Software Applications

The MC Toolkit has two software applications to work with STT750 SmartLine Temperature Transmitters:

• Field Device Configurator (FDC). This application is used for configuring, calibrating,

monitoring, and diagnosing HART devices. FDC conforms to the IEC 61804-3 EDDL (Electronic Data Desc riptio n Lang uage) stan dard specific ation. The FDC application is an open solution that supports devices with a registered device description (DD) file compatible with HART Communication Foundation (HCF) requirements.

Details for work in g with the MC Toolkit are provided in the MC Toolkit User Manual, document, #34-ST-25-50 (MCT404). In subsequent sections of this manual, explicit operating instructions are provided only in so far as necessary to complete required tasks and procedures.

3.4.2 Configuration Databases

The MC Toolkit is used to establish and/or change selected operating pa ram eters in a transmitter database.

3.4.3 Configuration

Configuration can be accomplished both online and offline with the transmitter powered up and connected to the MC Toolkit. Online configuration immediately changes the transmitter operating parameters. For offline configuration, transmitter operating characteristics are entered into Toolkit memory for subsequent downloading to a transmitter.

When you set up or configure a transmitter, it can take up to 30 seconds for the value to

be stored in it. If you change a value and transmitter power is interrupted before the change is copied to nonvolatile memory, the changed value will not be moved to nonvolatile memory.

4 HART Transmitter Configuration

4.1 Overview

Each new STT750 Temperature Transmitter configured for HART protocol is shipped from the factory with a basic configuration database installed. This basic configuration database must be edited or revised to meet the requirements of your process system. The process in this section assumes that you will use the Field Device Communicator (FDC) application for HART configura tion tasks. The FDC application provides the facilities for the online and offline configuration of trans mitters operating with HART protocol

Online configuration requires that the transmitter and MC Toolkit are connected and communication between the two has been established. Online co nfiguration provides a set of functions with which to perform various operations on a HART communication network through an active communication link. These operations primarily include configuration, calibration, monitoring, and diagnostics. Typically, these operations could be realized through various constructs exposed by the Device Description (DD) file. In addition, the FDC application provides some functions for convenient execution of these functions.

Offline Configuration refers to configuring a device when the device is not physically present or communicating with the application. This process enables you to create and save a configuration for a device, even when the device is not there physically. Later when the device becomes available with live communication, the same configuration can be downloaded to the device. This feature enables you to save on device commissioning time and even helps you to replicate the configuration in multiplicity of devices with lesser efforts. Currently, FDC does not support creating offline configuration. However, it supports importing of offline configuration from FDM R310 or later versions. The configurations thus imported can be downloaded to the device from FDC. The following are the tasks that you need to perform for importing offline configuration in FDC application software and then downloading it to the device.

• Create offline configuration template in FDM

• Save the configuration in FDM in FDM format.

• Import the offline configuration in FDC

• Download the offline configuration to the device

Note: For details on creating and using offline configuration, refer to section Offline configuration in FDM User’s Guide.

4.1.1 Personnel Requirements

The information and procedures in this section are based on the assumption that the person accomplishing configuration tasks is fully qualified and knowledgeable on the use of the MC Toolkit and is intimately familiar with the STT750 family of SmartLine Temperature Transmitters. Therefore, detailed procedures are supplied only in so far as necessary to ensure satisfactory configuration. The other HART configuration tools are Honeywell Experion in conjunction with FDM, iDTMs running on FDM or Pactware, and Emerson 375/475. The organization of Device Configuration and Parameter Descriptions on page 24 is given in

4.2.1 Settings

Use this feature to customize FDC. You can customize FDC for device detection, DD selection, and other application settings.

4.2.1.1 Device Identification

Use the following options to configure FDC to identify a device.

• Using Poll Address

− Use poll address 0 only: Use this to detect a device with the poll address as zero.

− Find first poll address and use: Use this to detect a device with the first available

poll address in the range of poll addresses that are avai lab le.

− Use selected poll address: Use this to detect a device with a specific poll address in

the range of zero to 63.

− Use From: Use this to detect a device based on a range of poll addresses.

Using Device TAG: Use this to detect a device with a known HART tag.

•

Using Device LONG TAG: Use this to detect a device with a known HART long tag

•

(applicable for devices with HART 6 or later Universal revisions).

Note: If you choose the option Using Device TAG or Using Device LONG TAG, FDC prompts you to enter a device tag/long tag name during device detection.

4.2.1.2 DD selection

Use the following options to configure FDC to select DD files when a DD with matching device revision is not available.

- Use DD file of previous device revision: Use this option to automatically communicate using

a DD file having device revision lower than that of the device.

- Use generic DD file: Use this option to automatically communicate to the device using an

appropriate generic DD file.

- Always ask user: Use this option to always prompt you with a choice for communicating to

the device either using the previous device revision or using a generic DD file.

- Always Use Generic: Use this option to always communicate to the device using generic DD

files even if a DD file with matching device revision as the device is present.

Note: A generic DD file is a DD file that provides access and interface to the universal data and features of a HART device.

4.2.1.3 Other settings

Low storage notification: Use this option to set a percentage value and to notify you with a warning message when the available storage card space is less than the percentage set. Application diagnostics: Use this option to enable or disable the logging infrastructure for application diagnostics. With this option enabled, FDC creates necessary log files for troubleshooting and diagnostics. These files are stored in SD Card\FDC folder. Note: You must not enable this option unless suggested by Honeywell TAC because this may impact the application performance.

4.2.2 Manage DDs

Using this feature, you can manage the DD files installed with FDC. A DD file contains descriptive information about the functionality of a device. By default, a set of DD files are installed with FDC.

However, if you do not have a DD for a given device, you can install it using the “Add DD” feature. Similarly, you can uninstall a DD file or a set of DD files using “Delete DD” feature. You can also directly copy the DD files in appropriate hierarchy using a card reader or “Active Sync/Mobile Device Center” mechanisms. In such a case, you should validate the library view using the “Refresh” feature.

4.2.2.1 Overview

Using Manage DDs, you can view, add, or delete DD files for devices. A list of already available DD files is maintained in the DD Library. FDC lists the installed DD files in a hierarchy as below:

Manufacturer

Revision 3.0 STT750 Series HART Option User’s Manual Page 17

4.2.3 Online configuration

Using online configuration, you can configure, calibrate, monitor and diagnose a HART device which is connected to MC Toolkit. FDC provides the features to perform these functions through the various constructs offered through the DD file of the device. Besides there are certain other features available under this link for you to conveniently work with a HART device with live communication. After making changes to the device you can also save a snapshot of the device data as history to later transfer it to FDM for record and audit purposes.

4.2.4 Offline configuration

Offline configuration refers to configuring a device offline (without physically connecting to the device) using a template and then downloading the configuration to the device. Presently, FDC application software does not support creating offline configuration. However, it supports importing of offline configuration from FDM (R310 and above).

4.2.5 Online Configuration Overview

Online Configuration option provides you a set of functions with which you can perform various operations on a device with an active communication link. These operations primarily include configuration, calibration, monitoring, and diagnostics of a HART device. Typically, these operations could be realized through various constructs exposed by the DD file of the device. In addition, FDC also provides some additional application functions for you to perform these functions more conveniently.

Online configuration includes a set of functions to perform various operations on a transmitter with active communication link. These operations primarily include:

• Identifying a transmitter

• Reading and reviewing transmitter variable values

• Editing transmitter variable values

• Downloading the selected/edited variable set to the transmitter

4.2.5.1 Detecting and loading a device

Tap the Online Configuration button on the Application Home page.

The device detection and loading process automatically gets started. Depending upon the Device Detection and DD Selection settings you may have chosen, you may be prompted for certain inputs as described in the Settings section.

Page 18 STT750 Series HART Option User’s Manual Revision 3.0

4.2.6 Overview of Device Homepage

Once the device is detected and loaded successfully, you can view the device homepage for the identified device.

The workspace area on the device homepage consists of 4 tabs on the left hand side. Selecting a tab displays functions/information associated with that tab on the right hand side.

Figure 7 – Device Homepage

Table 5 lists the device health status and their indications.

Revision 3.0 STT750 Series HART Option User’s Manual Page 19

4.2.7 Tabs on the Device Home page

The following are the options that are available on the device homepage

• Information tab: Use this option to view the device identity related information. You can

view the manufacturer name, device type, device revision, DD revision, and universal revision of the HART device.

• Functions tab: This tab provides various options which you may use for navigating

through the device specific user interface and some standard features offered by FDC across all devices. For the sake of explanations, the right side options under this tab shall be referred as “Entry points” throughout the rest of the document.

Page 20 STT750 Series HART Option User’s Manual Revision 3.0

• My Views tab: Quite often, you may be interested only in a set of variables of a device.

But navigating through the menu tree of a device may not be helpful because of time and further all variables that you want may not be in the same location. Using this unique feature of FDC, you can now choose what you want to view in a device in your own views. FDC allows you to create two such views per device revision of a specific device type. You can always modify them as per your needs.

• Tools tab: This tab is a placeholder for FDC specific tools for providing certain functionality.

Currently t he only option it provides is called as Save History. Using thi s option you can save the snapshot of the device variables. This snapshot is saved in a format which can be later imported as a history record in FDM.

Revision 3.0 STT750 Series HART Option User’s Manual Page 21

4.2.8 Using FDC for various device operations

Typical operations with a smart field device involve configuration, calibration, monitoring, and diagnostics. FDC enables you to achieve these operations with a HART device via the various interfaces/constructs exposed through the DD file of the device.

The “Functions” tab under the device home page provides the entry points for navigating through the device specific user interface to perform the above mentioned operations. A device may define up to four entry points in the DD file. All devices shall have at least one entry point, generally referred to as “Online”. Besides the device specific entry points, FDC provides custom entry points for navigational aids to specific ty pe s of information/features. One such entry point is called Device Status, which is used for reviewing device health. Another is called Methods List, which is used to navigate to all the methods available in a device.

All of the device specific entry points represent the device interface, as explained using the Online entry point as an example. All the other device specific entry points have a similar interface except for the fact that the variables and other DD constructs provided under each may vary as indicated by the title of each entry point.

For the sake of explanation, the pages that appear on navigating through the device specific entry points are referred to as “Device Configuration” pages in this document. However it must be noted that this does not prohibit you from performing other device operations as explained above.

Page 22 STT750 Series HART Option User’s Manual Revision 3.0

Online Device Entry Point: When you tap on to open the Online tab, the device configuration screen appears as shown below. Typical Online Menu is shown below. Based on the connected Device type, Menu items will be shown

Alternately you can access the full EDDL features by selecting the “My Device” Tab. Typical My Device Tab is shown. Based on the connected device type Menu items will be show n

Experion PKS. When a HART device requires maintenance, the engineer or the operator changes the PV Source value of the corresponding AI channel to MAN. As soon as the PV Source value is changed for the channels connected to the STT850 transmitters, Experion communicates the channel mode status to the corresponding STT850 transmitters. Upon receiving this status, if the value is MAN, the transmitter displays an M and Available for Maintenance on the local display of the transmitter. The status display on the transmitter ensures that the field technician can locate and perform the maintenance work on the correct transmitter without impacting the integrated devices in the process loop. The transmitter continues to display the Available for Maintenance status on its local display until the PV Source status of the corresponding AI channel is changed to AUTO / SUB or the transmitter is power cycled.

5.3 Calibrating Analog I nput s

The STT750 SmartLine Temperature Transmitter supports two-point input calibration. This means that when two points in a range are calibrated, all points in that range adjust to the calibration. LRV and the URV should always be calibrated both at the same time.

This procedure assumes that the transmitter has been removed from the process and is located in a controlled environment.

IMPORTANT! You must have a precision calibrator source with an accuracy of 0.02% or

better to do an input calibration. Note that the factory calibrates STT750 SmartLine Temperature Transmitters temperature in deg C.

Sensor Input Calibration (Corre cts ) Proced ur e

• Ensure transmitter is not in Write Protection Mode and operational without any critical fault.

• Ensure sensor type configured in transmitter matches with sensor input connected to

transmitter terminals from accurate source or simulator

• Configure Lower Calibration Point (Lower Calib Point) & Upper Calibration Point (Upper

Calib Point) available from the Online/Device Settings/ Calibration and Correction Record/ menu, which are used to perform 2-point calibration. T hese cal ib ration po ints can b e same or different from LRV & URV

• The calibration points can be accessed by navigating menus as mentioned below on any

HART compatible handheld device using Honeywell STT750 DD files

Lower Calibration point: Online/Device Settings/ Calibration and Correction Record/Sensor 1 Calibration/ Sensor Lower Calib point

Upper Calibration point: Online/Device Settings/ Calibration and Correction Record/Sensor 1 Calibration/ Sensor Upper Calib point

• To perform Sensor input LRV and URV correct, navigate menus through Online/Device

Settings/ Calibration and Correction Record/Sensor 1 Calibration

• See Figure 6 for typical test connections. Connect the power supply and communicator to the

signal terminals of the transmitter terminal block.

• Connect the precision calibrator source to the sensor (to be corrected) inputs of the transmitter.

• Turn on the power supply and allow the transmitter to become stable.

• Turn the MC Toolkit on, start the FDC application.

• On the FDC Home page, select Online, and establish communication with the transmitter.

Note : The field calibration data of sensor gets defaulted in the device when,

a. Sensor type or id changed b. When RTD wire changed from 3 wire to 4 wire and vice versa c. CVD enabled/disabled

5.3.3 Resetting Calibration

STT750 SmartLine HART Temperature Transmitter can erase incorrect calib ra tion data by resetting the device back to final fac tory calibration, which is performed per the ordered range. The Corrects Reset command returns the zero and span calibration factors to the original precise factory calibration. Incorrect or inaccurate user calibrations may be reset by performing a Reset Correct operation. This calibration reset will return the device to original factory calibration accuracy. Factory calibration is extremely accurate and user calibration is not typically recommended. However, if user calibration to a customized range is desired, it is recommended that the input calibration procedures be performed again after the calibration reset.

The following procedure is used to reset calibration data to factory calibrated range using the communicator.

1. Connect the MC Toolkit per Figure 5 across the loop wiring and turn on.

2. Turn the MC Toolkit on, start the FDC application.

3. On the FDC Home page, select Online, and establish communication with the transmitter.
