Creating new Digital Status tag and below I/O device, and next to bit 0 address there's usually a box that lets you drill down to the PLC tag. One out of seven times, it isn't there.

Any advice appreciated!

Only appears under drivers that retrieve tag information from the PLC [CIP]

But a shut down and restart fixes it. Weird.

If these are all on the same subnet you should make sure the gateway IP is set on all the PLCs.

Great point. I actually didn't make sure of that. I will first thing tomorrow. Thank you Mel.
