I wrote a fairly basic program using full version of studio 5000 v30 that works well. Today I tried to add a few more rungs to control motor starters via push buttons.
I made the changes offline, downloaded the new program to the PAC and placed it back in run mode. The new rungs will not work, I can push the buttons and see the rung prove true but the output will not turn on. I can force the output and it works fine.
There are no faults or warning, the rungs were added to an existing routine, everything else (existing) works fine. I even went back and added some very basic I/O and I can force the output but it will not work on its own even if I force the Input.
I spent 8 hours wracking my brain on this and have run out of ideas to try. I thought about wiping the controller (1769-L36ERM) and starting over but I don't want to end up with a $4k paper weight .
