CAUTION!
If you set mA Output Fault Action or Frequency Output Fault Action to None, be sure to set Digital
Communications Fault Action
Communications Fault Action
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.
Restriction
If you set Digital Communications Fault Action to NAN, you cannot set mA Output Fault Action or Frequency
Output Fault Action
Output Fault Action
to None. If you try to do this, the transmitter will not accept the configuration.
