Viewing DTMs for Field Instruments

Use the Address Table dialog to view a list of HART field instruments that have been added in the DTM Browser . Each channel links to only 1 instrument.

The Address Table includes the following properties for each detected field instrument:

The Address Table dialog display refreshes at the rate of 1 channel per second. When a DTM for a new HART field device is added, the Address Table dialog automatically assigns the new instrument a channel number. Use the Select channel dialog to change the channel assignment so that it indicates the channel to which the instrument is connected.

Use the Rescan button to perform a scan of each connected field instrument DTM, and update the Matched State field for each channel.
