How can CP600 HMI switch IP address between AC500-HA Redundancy system
How can CP600 HMI switch IP address between AC500-HA Redundancy system?
Is there any lib or sample program for this application?
I was think not to have two sets of GUI on one HMI with different IP address as its not practical to duplicat GUI with different IP address.

Additional tips for you:
1. Create a pair of connection to monitor HA variables (in global)
2. Create a real variable connection with Node Override IP to primary IP.
4. Switchover when state change using project.setTag on Node Override IP.
You have the posibility to change from which IP you get the variables. Using the system variable Node Overide IP. It can be used with ABB Codesys ETH and ABB Modbus TCP drivers.
If you define 2 protocols that monitor your 2 redundancy servers so you can see which are active. Then you can control the protocol IP with the before mentioned system tag.
