Diagnostic Data
The 1771-OFE module has 8 bits of diagnostic data that can be
mapped to a flag read tag.
The good communication bit is set if the 1757-ABRIO module is
successfully communicating with the 1771-OFE module.
The data invalid bits are set if the value written to the channel is
outside the range of the scaling values entered in the configuration
dialog.
