Synchronizing the system time in the
Figure 49: PTP Global dialog

Application example:

PTP is used to synchronize the time in the network. As an SNTP client,
the left device gets the time from the NTP server via SNTP. The device
assigns clock stratum "2" to the time received from an NTP server. Thus
the left device becomes the reference clock for the PTP synchronization
and is the "preferred master". The "preferred master" forwards the exact
time signal via its connections to the RT module. The device with RT mod-
ule receives the exact time signal at a connection of its RT module and
thus has the clock mode "ptp-mode-boundary-clock". The devicees with-
out an RT module have the clock mode "ptp-mode-simple-ptp".
