When I turn on my T50 power panel, the screen goes black and nothing happens. If I push the backside button while turning on the panel, it blinks and goes to a command page with the lines:
PPT-Updatesystem
ppt50 login:
But even conecting a mouse or keyboard, no input is detected.
I believe the firmware is corrupted, is there a way I can factory restore this panel?
I have no idea what the purpose of the button is. I believe it’s not officially documented since it’s not accessible on a chassis.
Every update procedure documented in the help requires accessibility of the Service pages. That’s why I don’t see any other option apart from contacting a local B&R office and sending the T50 for a repair.
But maybe somebody else in the Community could help you.
