6.7.1 Failover reactions of OS clients with permanent operability
Functionality
If the network for the configured OS server is interrupted, the process values on the OS clients
are no longer updated and process control is no longer possible. Other OS clients connected
to the redundant OS partner server are not affected by this. The plant operator can therefore
switch to these OS clients, if needed.
