1756-IF8H Fault Reporting The graphic below offers an overview of the fault reporting process for the
1756-IF8H module.
If set, any bit in the Channel Fault word also sets the
Analog Group Fault in the Module Fault word.
A channel calibration fault
sets the calibration fault in
the Module Fault word.
An underrange, overrange condition
sets appropriate Channel Fault bits.
When the module is calibrating, all
bits in the Channel Fault word are set.
Alarm bits 0…4 in the Channel Status word do not set additional
bits at any higher level. You must monitor these conditions here.
