5 4 3 2 1 0
15 = AnalogGroupFault
13 = OutGroupFault
12 = Calibrating
11 = Cal Fault
14 is not used by the
1756-OF6CI or
1756-OF6VI.
5 = Ch5Fault
4 = Ch4Fault
3 = Ch3Fault
2 = Ch2Fault

4 = Ch5InHold 15, 13, 11, 9, 7, & 5
are not used by the
1756-OF6CI and
1756-OF6VI in
integer mode.
If set, any bit in the Channel Fault word, also sets the Analog
Group Fault and Output Group Fault in the Module Fault word.
When the module is calibrating, all bits
in the Channel Fault word are set.
