Hi,

How can I time sync between S7-400H as a time master and TP1200 as a time slave?My program for S7-400H is in STEP7 ver5.6 and and program for TP1200 is TIA Portal V17.

Thanks

Hello smb1797

If you use a solution like this:

you can use the area pointer for "Date/Time PLC". this should also work if you use the changeconnection

As an alternative you also can use a NTP server for time synchronization in the network
