● The OS server must be the time master on the plant bus
● All automation systems must be configured as time slaves.
● Restriction: CPU 416-3- PN/DP and CPU 414-3 PN/DP cannot be used in this
configuration (synchronization lacking).
Setting the terminal bus
To configure the OS server for time synchronization, proceed as follows:
1. Open the OS server in the PCS 7 project on the engineering station.
2. Select the "Time synchronization" editor from the tree view of WinCC Explorer.
