Additional Communications Response Delay is used to synchronize Modbus
communications with hosts that operate at a slower speed than the device. The
value specified here will be added to each response the device sends to the host. The
default value is 0. Valid values range from 1 to 255.
Tip
Do not set Additional Communications Response Delay unless required by your Modbus host.

Overview
Digital Communications Fault Action specifies the values that will be reported via digital
communications if the device encounters an internal fault condition.
Procedure
Set Digital Communications Fault Action as desired.
The default setting is None.
Restrictions
• If mA Output Fault Action is set to None, Digital Communications Faut Action should also be set to None. If
you do not, the output will not report actual process data, and this may result in measurement
errors or unintended consequences for your process.
• If you set Digital Communications Fault Action to NAN, you cannot set mA Output Fault Action to None. If
you try to do this, the transmitter will not accept the configuration.
