I am not sure if everyone completely understands this just yet, do you mean the process in the PLC starts automatically? If so, can you isolate the permissive rung, and see if you an isolate the issue that way? That is where I would be starting.
It definitely sounds like a very dangerous condition, and that the PLC code maybe is not as robust as it needs to be....
No, the process in the PLC did NOT start automatically. It's the main display in PV+ that starts automatically.
I should clarify that when the display in PV+ shows that it's running, the PLC is NOT running. Nothing is being energized. Even when I download the PV+ application to the PV+ terminal, and connect it to the PLC and all the equipments, nothing is energized and nothing is actually running, except that the PV+ displays are showing that they are running. Does this make sense? So I don't think it's the PLC problem here.
OK So I'm trying to attach the PV+ apa file here. But um... where do I find that apa file? I'm a complete newbie and this is my 1st time using PV+. Please forgive my stupid questions.
