Backup CPU Ethernet Channel failure in redundant configuration of PM861
We have PM861 in redundant configuration.
when we download the program in CPU then both the LED(Tx & Rx) of CN1 of Primary blinks but in backup cpu only Rx LED blinks.(Here network redundancy is not used, Only CN1 Port is used)
If we disconnect the ethernet cable from primary cpu then communication fails. But if we switchover the CPU then same problem ocures with backup cpu only.
Every time the ethernet warning comes in harware configuration.("No communication BackupCPU." as screen shot)
This works fine with a different CPU units.
I have checked all ethernet configurations but unable to sortout the problem.
