PM865 backup CPU error
I think that at atime of program download backup cpu went to error state.
Aftr controller reset Primary cpu blinks dual and after 2-3 minutes shortly lits dual on bouth controllers and after that backup cpu goes to error state. I added log files, meybe someone will find helpfull information

As per Controller log there is mismach in modulebus Cluster
I 2018-03-22 09:32:54.885 Clusters visible from primary: 1111000
I 2018-03-22 09:32:54.886 Clusters visible from backup: 1110000
In a redundant configuration an automatic switch-over from the Primary CPU to the
Backup CPU occurs in the following situations, provided they are in synchronized
state (DUAL LED is lit):
• Memory error in the Primary CPU.
• Other HW-error in the Primary CPU, which causes CPU crash.
• Severe communication errors on the Control network, that is, loss of both
network ports in the Primary CPU.
• Severe communication errors on the ModuleBus (if ModuleBus is part of the
HW configuration) that is, loss of clusters in the Primary CPU.
Note: that a Backup CPU with severe communication errors on the ModuleBus
will be rejected (if ModuleBus is part of the HW configuration) and
synchronized state will never be reached as long as error remains.
