I have an Rx7i Redundant Controller having a Single Genius Bus Network i.e Each Primary and Secondary rack have one GBC. This has happened three times now that when I make both the PLC`s live the redundancy seems to be working fine. But after a few days none of the devices can be controlled by the HMI.Both racks RMX cards show locally ACTIVE. If I STOP one PLC(Active) then all things return to normal. Any ideas why it happens?
