Having an issue writing data to an AB Compact Logix PLC. So far I have made a few buttons, labels, and number fields. Basically everything reads values from the PLC but I have not been able to write anything to the PLC.
Item: Pushbutton
Value: CompactLogix.pb
Tag Info
Name: pb
write_expression: CompactLogix.pb
I had tried that previously but there was an error message. Unfortunately I couldn’t see it because it was hidden under the keyboard. I’ve experienced that a lot. I’ll try it again later, hopefully I had I typo.
