communication idle mode (program mode for most PLCs and DCS

When a communication fault occurs the relays can execute two types of
behavior. The behavior is selected on a per bit basis. Only valid for output
relays used as general purpose field outputs. See Communication Loss
Behavior parameter to set the behavior of outputs used in the control
profile. Each available output is assigned a bit in the Comm Fault Output
Action word. If the bit is “0” then the state of the output is determined by
the (Comm Fault Output State) Parameter. If the bit is “1” it will hold last
state.

This parameters works with the Comm Fault Output Action parameter.
Only if that parameter is set to Use Fault State does this parameter apply.
This parameter then selects the state of the outputs, On or Off when a
communication fault occurs. The behavior is selected on a per bit basis.
Only valid for output relays used as general purpose field outputs.
