Configuring the OS server for time synchronization
To configure time synchronization for the OS server, 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.
3. Select Open from the shortcut menu.
The "Time Synchronization" dialog box opens.
4. Select the check box "Synchronization via terminal bus (slave)".
Thus all associated check boxes and text boxes are active.
5. Select the "Accept time from permanently defined computers".
6. In the "Computer 1" text box, enter the first domain controller (DC1) and enter the
redundant domain controller (DC2) in the "Computer 2" text box.
7. Select the check box "Synchronization via plant bus (master/slave)".
Thus all associated check boxes and drop-down list boxes are available for selection.
8. Select the check box "Display symbolic names of the access points". This will display the
communication modules of the OS server with symbolic names, if they are not available
on the engineering station.
