Deactivating and activating non-redundant OS servers
Deactivating
If a non-redundant OS server is deactivated, process operation cannot continue with the
corresponding OS clients.
1. Check to determine when the OS server function will not be necessary.
2. Check the configuration of the PCS 7 plant.
3. Check the plant status of the PCS 7 plant.
4. Check that the OS server is functioning correctly with the help of an OS client.
5. Deactivate the runtime of the OS server.
Note
In the case of a server shutdown you can, for example, operate an OS single station
system in parallel to the OS server for emergency opera
tion. The PCS 7 engineering
system does not support synchronization of the OS server and the OS single station
system in the PCS 7 project.
The OS single station system must be fully installed, configured, and licensed for
emergency operation.
The functionality of the client-server system needs to be checked once the OS server has
been activated. Read the section titled "Checking the OS functionality after restarting an OS
server (Page 31)" for more information.
1. Open the OS project on the OS server.
2. Activate Runtime on the OS server.
3. Check that the OS server is operating correctly.
