B&R PLC CPU Service mode

Hi Friends,

I have a issue with B&R PLC brand and my CPU X20 CP 1484 suddenly gone into service mode and i cant able to reset and get it back to operational mode .So Could you please help me some to get resolve

Thank you.

Maybe you can find something in this manual:
https://www.br-automation.com/en/do...ontroller/x20cbc0087/x20-system-users-manual/

It seems that the CPU 1484 is not in this manual, but 1483 and 1485 are (!?).
On page 1384 you can find descriptions for the LEDs on the 1483. Maybe the discriptions are valid for 1484 as well.
