How often does the Lenze controller c5x0 synchronise the system time with the NTP server?
Answer:
If the time base of the system time is set to 'NTP [0]' in parameter 0x245B:001, then the system time is synchronised with the NTP server once. After that, the Lenze controller synchronises the system time with the configured NTP server every hour (every 3600s).
The Lenze controller c750 has two operating systems. The Windows IoT side synchronises its time and date every second to that of the PLC side (Linux operating system) of the controller. The time base of the PLC side can be set to the internal real-time clock of the controller or to an external NTP server (see above). Therefore, the Windows IoT side must not also be synchronised to an external NTP server.
