I was messing around with a Compactlogix processor, and I found that if I try to read a Program tag, I get an error.
Invalid Tag Address. CIP Status4
Controller tags work fine.
My solution is to Copy the Program tag array in the PLC over to a controller tag array.
I then referenced the controller tag because I know that works.
AdvancedHMIv35'
Is there something else that I could have done in order to read Program tags?
