HART Configuration Quick

Start

To get your module started with HART features, follow these quick set up

procedures.

Pick HART Input Data Format

To set the module to collect data from your HART instrument and place it in

the Input Tag, choose the Comm Format "Input Data and HART PV" when

adding the module to your I/O Configuration. If you choose "Input Data",

you can access HART data via Pass through messages, but it is not included in

the module's Input Tag data. If you know that you will not be using these

HART variables in your control logic then choose "Input Data".

Enable HART

In the module configuration tag "ChXHARTDisable", make sure the value is

"0" for each channel that is connected to a HART device.
