Working on a model PFXGP4501TAA panel that's been in operation for 5 years. It communicates with a SLC500 over RS232. Today the HMI screens would no longer switch nor the the tocuh cells seemed to work. It locked up while running production.
We tried to power cycle but no change - it stayed locked on main/powerup screen. Also I could not get into the setup menu (pressing opposite corners) which is a bit tricky. Gave up on that quickly thinking locked touch cells would prevent that too. We turned the power off and went to research a new unit in the office. After 15minutes I returned to try entering the setup again. Now the unit worked as before.
This issue is something new to me. The question now is if this will happn again (heat issue, weak component) or if it locked up for another reason (communication to PLC?). Looking for advice...
