11.1 Introduction

ST 700 HART and Fieldbus 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 ST 700 HART DTM on Pactware (Version 4.1 or above).

11.2 Components

In order to be able to use the HART DTM you need the following:

PACTware or some other Container application.

Microsoft .NET Framework

Latest HART Communication DTM: Free version of HART Communication DTM available
for download from CodeWrights website.

Honeywell HART DTM Library

Viator modem from MacTek: RS-232 interface for HART Networks

11.4 Procedure to Install and Run the DTM

1. Install the Downloads 1, 2, or 3 above.
2. Connect the Transmitter to the 30V DC power supply with a 250ohm loop resistor.
3. Connect the Viator modem terminals to the Transmitter power terminals.
4. Connect the Viator modem DB9 connector to the PC COM port.
5. Run Pactware. Click Update Device Catalog before adding Device (before adding HART
Comm DTM).
6. Add Device – Add HART Comm DTM.
7. Right-click HART DTM, click Connect.
8. Right-click HART Comm DTM and click Add device.
9. Add the Device DTM from for your device from the list (for example: ST 700 DevRev 1).
10. Right-click Device DTM, and click Connect.
11. Right-click Device DTM, and click Parameter/online parameterization. You should see
Status "Connected" to be able to do configuration, calibration etc.
12. Browse through the menus to access various parameters/functions.
The following sections provide a high level overview of ST 700 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
details. In the following sections, emphasis is given to show the various DTM screens.
