Flex I/O - 1794-IE8 - Fault and Status

Can anyone give me an idea of what the I.Fault and I.Status represent on a 1794-IE8? I can't locate this info in any documentation.

See link... Chapter 3

I've read that chapter numerous times. Nowhere does it mention Fault or Status. Ditto on the appendix entry (data map) for the IE8.

I'll state that I'm new to Rockwell. Am I missing something which would be obvious to someone with experience?

I think that the I.Status word contains all the .Underrange and the .PowerUp bits that appear underneath it in the RSLogix 5000 module-defined Tags.

The bit positions should be the same as are shown for Input Word 8 at the bottom of Page 44 of that User Manual.

As a practical matter you can use the explictly-laid-out .ChXUnderrange and .PowerUp sub-element tags in your logic.

I don't know the contents of the .Fault word. It's possible that it indicates a module self-test failure or something else that would be uncommon or difficult to test.
