How configure Modbus TCP communication with redundant Freelance 800F

We connected an ABB proces panel PP877(master) with redundant 800F controllers over Modbus TCP/IP. Now, we want to use the process panel even if one of the CPU is down. Please tell me how to configure the system? Do we need to specify both IP Station address on ABB Panel Builder6.0? Use process station IP1 or IP2?

Thanks,

Hi,

Yes, in setup or under tags in panel builder6.0 one need to provide both primary and secondary controller ip. so when primary controller is down panel knows secondary controller ip and remain connected to read/write values.
