6.1 How to check the time of the PC stations
Introduction
The following control system message is displayed if time synchronization is disturbed at an
OS, for example:
"LAN-Sync: Time synchronization with PC <xxx> is disturbed".
Requirement
It must be possible to operate the operating system environment.
It must not be possible to execute the w32tm function if command prompts have been
disabled in the process mode (runtime) configuration. If you wish to use this function, you
must change the configuration for process mode.
Methods for checking the time
You can check the time of PC stations in the PCS 7 plant by using the operating system
function "w32tm". Use the "w32tm" operating system function to set the time difference to an
additional computer.
Note
Further information about the w32tm command is available by entering the string "w32tm/?"
in the Windows command prompt.
