Hi,

I have CRU320 CPU with two RMX128 modules on Primary and Secondary rack works as a redundant system.

Some how if the fiber link between two RMX128 of Primary and secondary is not working which makes both PLC as active and creates confusion :oops: to machine for its operation.

Can anyone help me on this issue?
