Implementation of (S)NTP client and (S)NTP server is based on protocol version 4.
For (S)NTP server configuration add a new object “SNTP Server” under of the available “Ethernet interfaces (ETH1-ETHn)”.
For a PLC only one instance of an (S)NTP server is possible.
The following parameters are available:
Not all parameters are shown in the user interface.
It should not be necessary to change the default values of the other parameters for the most applications.
But there is the possibility to edit them in the generic parameter editor.
