STT700 Series HART/DE Option User’s Manual
Revision 1
10 - DTMs
10.1 Introduction
STT700 HART models support DTMs running on PACTware or FDM / Experion. To set up the DTM
network on the FDM/Experion, refer to the
FDM/Experion User Guide
. In this manual, the procedure
is given to run the STT700 HART DTM on PACTware (Version 4.1 or above).
10.2 Components
In order to use the STT700 HART DTM, the following items are recommended:
PACTware or some other container application.
Microsoft .NET Framework
Current HART Communication DTM
o
Free version of HART Communication DTM is available for download from
CodeWrights website.
Honeywell HART DTM Library
HART USB or RS-232 modem
o
Viator modem from MacTek

10.4 Procedure to Install and Run the DTM
Install the Download 1, 2, or 3 from above.
Connect the transmitter to the 30 V DC power supply with a 250 ohm loop resistor.
Connect the Viator modem terminals to the transmitter power terminals.
Connect the Viator modem connector to the PC COM port.
Run PACTware. Select Update Device Catalog before adding Device (before adding HART
Comm DTM).
Add Device – Add HART Comm DTM.
Right click on HART DTM, select Connect.
Right Click on HART Comm DTM and select Add device.
Add the Device DTM from for your device from the list (for example: STT700 DevRev 1).
Right Click on Device DTM, and select Connect.
Right click on Device DTM, and select Parameter/online parameterization. Status should
display “Connected” which then allows configuration, calibration etc. to be done.
Browse through the menus to access various parameters and functions
The following sections provide a high level overview of STT700 DTM screens. The menu structure is
similar to the MC Toolkit FDC application and behavior of the parameters / methods is the same as the
MC Toolkit FDC application. Refer to Table 9 for a complete listing of all the parameters and details.
In the following sections, emphasis is given to show the various DTM screens.
