need some help here figuring out how to find a status bit for this.

I have channel 1B cofigured to rio. I have several rio racks. couple of racks divided into quarters. See below for example.

Rack 2 Group 0
Rack 2 Group 2
Rack 2 Group 4
Rack 2 Group 6
Rack 3 Group 0
Rack 3 Group 2
Rack 3 Group 4
Rack 3 Group 6

Want to know if there is a bit/word that indicates the failure of a group in a rack. The S7 bit is too course and indicates a rack failure if any of the groups in the rack fail. I am witing diagnotic file N53 and can't find a bit or a word that correlates to a rack/group fault.

thanks that was what i was looking for. i did not define a data file for S:16, which is where the faults reside. I defined the data file for the channel and kept looking there, which was the wrong place.
