Why do I face 3 red leds on warm restart on my BMEP582040S

When power cycling an M580 Safety CPU rack, the PLC reboots, but both CPU and Coprocessor freeze with 3 solid red leds (ERR , ERR MS and ERR NS), then power cycling again the CPU rack leads to a Noconf state.

BMEP58x040S SV 3.10

Control Expert 14.1

This issue is diagnosed as a promptness problem of the Coprocessor boot time.

Some enhancement have been introduced as part of the Firmware SV 3.20 to reduce the boot duration of the Coprocessor. They are not mentioned in the Firmware History, but solve this particular case.
