Hello,

At the site we have anWinCC server with accompanied WinCC Project.
To the (redundant) server is a DCF77 antenna connected, and some operater cliënts via a LAN bus.
In the server there is also an N-PCImoduleconnected on which server communicates to the Teleperm CS275 bus. On the CS275 bus are several AS488 CPU's.

The problem is thatthe AS488 CPU system time is not synchronisedto the WinCC server time.
The system time of the Cliënts on the LAN busarehowevercorrectly synchronised when the time is changed on the server.

Does somebody know what might casue the synchronisation problem?
The documentation onlydiscribed the implementation of the DCF77 Service Tool and synchronising the operator cliënt on the LAN. But nothing is mentioned about time sync the AS488 system on theCS275 bus.

Thank in advance.

Best regards,

Rosegarden
