Status Indicators Appendix A
IMPORTANT The presence of any temperature warning indicates that measures must be taken to reduce the ambient temperature of
the module.
Instructions for how to use relay ladder logic to check for a minor fault can be found in the Logix 5000 Controllers Major, Minor,
and I/O Faults Programming Manual, publication
1756-PM014.
You can use a GSV instruction to read the MinorFaultBits attribute of the FaultLog class name. If the Diagnostics minor fault bit
(Bit 17) is set, a temperature minor fault can be present. Check the Minor Faults tab of the Controller Properties dialog box in
Logix Designer application to see if the minor fault is a temperature warning.
