In some projects there is demand for time synchronization for I/NET system. Unlike other Xenta Servers, Xenta 527 NPR does not have an entry for setting up an NTP server on the webpage of the controller.
Xenta 527 NPR
Xenta 527 NPR is just the IP router for I/NET system. So the web page of it is simpler than the one of other Xenta servers.
We can set the NTP server for Xenta 527 NPR through HyperTerminal. Refer to Connecting a serial cable to a Xenta 5/7/9xx controller for how to use HyperTerminal to configure Xenta 527 NPR.
After entering Xenta 527 NPR by typing username and password, type the command "time_date". Then type "timesynch" command. There will be several options for it:
- Set whether to let Xenta 527 NPR act as NTP server. For this parameter, just leave default.
- Assign the IP address of the NTP server.
- Set the refresh interval.
After these parameters are set, restart the controller. After the refresh time passed, it will synchronize the time with the NTP server.
