Non-redundant/Cold backup server
Hello
Currently we have a working project with one Zenon Server/Client on one machine, operating a substation with multiple IEC-104 and 61850 devices.
We have to add additional Client/ Second operator station and I am investigating the options to add additional/stand by server on that second PC.
The problem is, that I can not configure second connection to all clients/PLC/ for the standard software redundancy option.
Is there a way to have the stand-by server running without PLC connection, and enable this connections if the main one is offline? I realize, that some data can be lost, but for this project this is acceptable.
Another possibility is to have the main server work in network mode with two clients and prepare some simple instruction how to manually start a server on the back-up pc if the main server fails and goes offline for repairs.
