Overview

After you add a HART gateway DTM to the DTM Browser , you can then add a field instrument DTM.

NOTE: Before you can add a field instrument DTM, you need to confirm that the device DTM has been installed on your PC. If the desired field instrument DTM has not yet been installed, follow the manufacturer instructions for installation of the DTM.

When you next open Control Expert, a message is displayed indicating the DTM catalog is out of date. Click Yes to update the DTM catalog, and add the newly installed field instrument DTM to the list of available DTMs.

After a field instrument DTM has been added to the DTM Browser, you can use Control Expert to:

  • configure DTM properties

  • monitor dynamic DTM properties during run-time

Adding a Field Instrument DTM to the DTM Browser

To add a field instrument DTM to the DTM Browser, follow these steps:

Step

Action

1

If it is not already open, open the DTM Browser by selecting Tools > DTM Browser in the Control Expert main menu.

2

In the DTM Browser, navigate to and select a HART gateway DTM–for example, the DTM for the BMEAHI0812(H)–then click the right mouse button. A context menu opens.

3

Select Add. The Add dialog opens.

NOTE: If the DTM for the field instrument you want to add to the project has been installed, it appears in the Add dialog. If the DTM does not appear in the list, you need to install the DTM for the desired field instrument.

4

In the Add dialog, select the DTM for the field instrument you want to add (for example, the KROHNE TT51 field instrument) to the project, then click Add DTM . The Field bus discovery dialog opens.

5

In the Field bus discovery dialog, select the Channel setting for the newly added HART field instrument, then click OK . The Properties of device dialog opens.

6

In the Properties of device dialog, either accept the default Alias name or enter a new one; then click OK . The selected DTM appears in the DTM Browser beneath the previously selected HART gateway DTM.

7

In the DTM Browser, select the HART gateway DTM that is connected to the field instrument DTM that was added above; click the right mouse button; then select Open from the context menu. The fdtConfiguration window opens for the selected HART gateway DTM.

8

In the navigation control on the left side of the fdtConfiguration window, navigate to and select Address Table to display a list of field instruments that are connected to the HART gateway module.

9

In the navigation control on the left side of the fdtConfiguration window, navigate to and select Configuration > Parameter Configuration to display a list of configurable parameters.

10

Expand the CH-Enable parameter; select Enable for the channel to which the new field instrument is connected; then click Apply.

NOTE: If you cannot edit the CH-Enable channel settings, it is because this parameter is selected in the Process Data page and channels are dynamically enabled or disabled by operation of program logic. To enable a channel in the Parameter Configuration page, open the Process Data page, de-select the CH-Enable output parameter, then click Apply .
