Configuration Tab -
Output Module The following information describes how to configure the module’s input
channels.
Configure Individual Channels
With an individual channel button selected, use this table to configure the
parameters in the Channel box that apply to the individual channels.
Changes made to the parameters in
the Channel box only apply to the
individual channel that is selected.
Changes made to these parameters
apply to all channels.

Parameter Action Notes Available in
Hard Run Mode?
Enable HART Check or uncheck. • Unchecked by default.
• Output range must be 0…20 mA or 4…20 mA.
• When a channel is not enabled:
– HART messages are not sent on this channel.
– HART pass-through messages are not sent.
– HART data for this channel is not updated in the input tag.
• If you selected a HART PV or HART by Channel input tag input tag on the
General tab, process data (PV, SV, TV, and FV) from the HART instrument is
included in the input tag. If you selected Analog only, the process data is
not included in the input tag.
• Regardless of the choice of input tag, HART communication can be
enabled for each channel to provide pass-through HART message access.
If Enable HART is not checked, this pass-through message access is
not available.
• We recommend you Enable HART for any channel that has a HART device
connected so that information can be displayed on the HART Device Info
tab.
• One reason to disable HART communication is that each channel that is
enabled requires time to scan, so enabling unnecessary channels reduces
performance on the others.
