CIP Device WHO - meaning of status bits?

[dscish]

This is in an existing application, so stuff I've found and I'm trying to debug. I've got no Tech support contract, so can't view Tech Notes :/


There's a MSG instruction with a CIP Generic / Device WHO service running and a few of the Status bits are used to drive fault generation. From what I can see there's 16 bits in the status word which are packed into a ControllerDevice type tag, but I've got no idea what each bit means. If anyone has any info on what's what I'd appreciate if you could share it.


Thanks!

Sorry, forgot to mention, CLX / ControlLogix controller.

Thanks for the PM Mispeld!
