Fault Reporting in
Integer Mode The illustration offers an overview of the fault reporting process
in integer mode.

0 = Ch0Fault
15 = Ch0Underrange
14 = Ch0Overrange
13 = Ch1Underrange
12 = Ch1Overrange
11 = Ch2Underrange
10 = Ch2Overrange

9 = Ch3Underrange
8 = Ch3Overrange
7 = Ch4Underrange
6 = Ch4Overrange
5 = Ch5Underrange
4 = Ch5Overrange
Underrange and overrange conditions set the corresponding
Channel Fault word bit for that channel.
When the module is
calibrating, all bits in
the Channel Fault
word are set.
If set, any bit in the Channel Fault word, also sets the Analog
Group Fault and Input Group Fault in the Module Fault word.
A calibrating fault
sets bit 11 in the
Module Fault word.
