Some queries on system redundancy.
In zenOn, we can have dual redundant servers, 1 server as Main, the other 1 as Standby. In normal operation, the Main server will be responsible in polling the PLC. Does the Standby also polls the PLC at the same time? Or does it work like a client to the Main server?
