M340 time synchronization?

[szimano]

Hello,
I would like to ask how to synchronize the time in a PLC M340 P342020, when connecting the controller with a modem supporting NTP.
Whether to use any function blocks. I found a hint that I can handle it with the WRTC_DT function, but I don't know how to apply it.

I have an additional question about time synchronization with the use of the NOC0401 module, in which NTP time servers are declared. How to get information about this time from this module.
