Time synchronization

Before deactivating an OS server, you should check whether all computers in the PCS 7
plant are running in synchronism. System messages generated by the OS server are
assigned a time stamp by the OS server. If there is no time synchronization set for a
redundant OS server, for example, it is difficult to chronologically track the system
messages.
Note
You can find more information on time synchronization in manual "SIMATIC Process Control
System PCS 7 - Time Synchronization"
(https://support.industry.siemens.com/cs/ww/en/view/109746544).
