5. In the user program, assign the IP address 192.168.1.10 to the data type
"IF_CONF_NTP":
"NTP".NTP_Server.NTP_IP[1].ADDR[1] := 192;
"NTP".NTP_Server.NTP_IP[1].ADDR[2] := 168;
"NTP".NTP_Server.NTP_IP[1].ADDR[3] := 1;
"NTP".NTP_Server.NTP_IP[1].ADDR[4] := 10;
6. You change the IP address of the NTP server by generating a positive edge for the tag
"change_NTP-Server" in the user program.
"NTP"."change_NTP-Server" := true;
