Split from PCS 7 CPU410-5H System Time Setup.

Hi,

You will on the system (plant) bus need to define a Time Master. In best case this if you have a WinCC, you take the WinCC server or standalone as a time master. 

On the CP card or the PLC network interface please check the settings so that the time in accepted and forwarded to the CPU.

If you are still facing issues, let me know where and then we will try to find it.

If you have no WinCC installation, do you have somewhere an NTP Server avaialble? 

Kind Regards,
