Fault Reporting Example
Figure 10
shows an example of what bits are set when a ControlLogix high-speed
analog I/O module reports a Wire Off condition on output channel 0. Three
events occur, beginning in the Output Channel Status word.
Figure 10 - Fault Reporting for Wire Off Condition
The following sections provide a listing and explanation of the bits included in
each of the module’s fault reporting words.

When set, the I.Out0Fault bit (bit 4) sets the I.OutGroupFault bit (bit 13) and the
I.AnalogGroupFault bit (bit 15).

When set, I.Out[0].WireOff bit sets the I.Out0Fault bit (bit 4) in the
Channel Fault word.
When the Wire Off condition on channel 0 occurs, the I.Out[0].WireOff bit (bit 5) in the
Output Channel Status word is set.

Table 8 - Module Fault Word Bit Descriptions
Bit
Name
Description
Bit 15
I.AnalogGroupFault
Bit is set when any of the bits in the Channel Fault word are set.
Bit 14
I.InGroupFault
Bit is set when any of the input channel fault bits in the Channel Fault word are
set.
Bit 13
I.OutGroupFault
Bit is set when any of the output channel fault bits in the Channel Fault word are
set.
Bit 12
I.Calibrating
Bit is set when any of the module’s channels are being calibrated. When this bit is
set, all used bits in the Channel Fault word are set.
Bit 11
I.CalFault
Bit is set when an individual channel calibration fault bit, such as I.In[0].CalFault,
is set.
