Network Time Protocol (NTP)
Beckhoff RT Linux® IPCs use systemd-timesyncd for network time synchronization as standard. The internal time of an industrial PC is never absolutely accurate; with the Network Time Protocol (NTP), the exact time can be obtained from a time server and the local system time synchronized accordingly. Beckhoff provides a global NTP server pool for this purpose: ntp.beckhoff-cloud.com. This pool automatically provides suitable time servers depending on the geographical region. If no other server is detected in the network, an attempt is made to reach ntp.beckhoff-cloud.com.
cat /usr/lib/systemd/timesyncd.conf.d/50-beckhoff.conf[Time]
FallbackNTP=ntp.beckhoff-cloud.comThe systemd timesync client is configured via the file /etc/systemd/timesyncd.conf.
cat /etc/systemd/timesyncd.confTo check the status of time synchronization, use the command:
timedatectl status
