I have been experiencing momentary push button tags and/or the logic sticking.
Example: start/stop buttons. We can click the start button, the equipment will start and the start indicator will be displayed. When we click the stop button, the indicator will go out if we click and hold the stop button, but will become true again after we release the mouse button. The equipment will continue to run.
Current work around is by double or triple clicking the “stuck” button to clear the logic or tag, then we can stop the machine by the stop button.
This isn’t happening every day, can be different screens and isn’t the same button or display every time. It can go weeks or a few days and one or more buttons or indicating displays will get stuck.
I first took notice with 7.7 installed on an AB control logix v17
We have since upgraded to 7.8 and a newer AB processor with V20.55 and the issue has followed.
