AB Compact logix & Control logix drivers

While browsing AB device tags under Diagnostics >> Device there is a status tag.
Is there documentation that shows what the individual bits in this tag represent?

Its not the same as status bits in the AB GSV function.

The status tag changes when moving the AB program run switch between its positions.



It looks like the status value is read initially, but then gets replaced with whatever the driver is reading to determine “Run Mode” from then on afterwards. I’ll have to ask around to figure out what that actually is, and why it’s even doing that instead of using the status value.

Yep… looks like a bug. It SHOULD be the same status bits you can read with the GSV instruction, but it’s not.

It looks like it broke when someone attempted to start polling the status tag along with other processor status information instead of just on driver startup.
