When Configure HART Device is set to Yes for the 1718-IF4HB and 1718-
CF4H modules, a HART Command tab appears in the Module Properties
dialog.
In the HART Command tab, you can specify HART device parameters for each
channel. These values are sent to the HART device

When HART data is included in the input tag and a channel has HART enabled,
the 1718 Ex I/O HART I/O module automatically collects HART data and
places the most common Dynamic Process Data and Device Health information
directly in the input tag.
An overview of the HART data includes the following:
• HART Faults – At the beginning of the input tag included even if you
click Analog Only input data tag format. These faults indicate that HART
communication is not successful or that the field device is reporting a
problem such as Device Malfunction, Loop Current Saturated or PV out
of Limit. For example, Ch0HARTFault is set if Ch0Config.HARTEn is 0
or if no HART Field Device is attached.
