5.6 Configuring time synchronization for a PC station without OS
5.6.1 Overview of configuration steps
Introduction
In PCS 7, operator stations offer an integrated time synchronization option in the form of the
"WinCC time synchronization" application. PC stations without OS include, for example:
● Engineering stations
● SIMATIC BATCH stations without OS
● SIMATIC Route Control stations without OS
If SIMATIC BATCH or SIMATIC Route Control is installed on the operator station, the PC
station is synchronized via the time synchronization facility of the OS.
The following time synchronization options are available for PC stations without OS:
● Recommended: DCF77 Client Service
You synchronize the PC stations directly with a time master (e.g. central plant clock,
domain controller, operator station).
The central plant clock can be synchronized via GPS.
● Synchronization via NTP mode
You will find additional information on this topic in Section "
How to synchronize PC
stations using NTP mode (Page
121)".
Configuration steps for PC stations with DCF77 Client Service
The following table shows which configuration steps are necessary to synchronize the PC
stations:
Step What?
1 Install the DCF77 Client Service
2 Configure the DCF77 Client Service
