How can you set the time of an S7-300 CPU via Industrial Ethernet and via MPI?

Data synchronization over open communication between multiple field devices (S7-1200) and a head PLC (S7-1200/ S7-300/ WinAC).

 Hello,

Have a look there:

How do you synchronize the date and time between an operator ...

you will use a date/time tag in your winCC flexible and connect it (in variable list) to either a DB with an appropriate data field or a PLC variable.
