SNTP time server
You can use this parameter to enter the IP address of a SNTP time server. If
you are using a time server, the device uses the time of the time server as
the system time.
Be sure to enter a valid time server address that is not 0.0.0.0, otherwise it
will not be possible to connect to the device.
Synchronization interval
You can use this parameter to set the interval at which the device is to call
up the time from the time server.
Automatic daylight saving / standard time
You can use this parameter to activate the automatic switchover between
daylight saving time and standard time. Depending on the time zone (region)
set, the device switches automatically between daylight saving time and
standard time on the specified days.
Time zone
If the time information is transmitted to the device by a network service
(SNTP or SCADA), this time is transferred depending on the set reference
time. To adjust the device time to your local time, you can use the time shift
parameter to set the time shift to UTC.
Example:
Region Time shift to UTC
Mumbai, India UTC +5:30 h
Beijing, China UTC +8:00 h
Brasilia, Brazil UTC -3:00 h
Table 19: Time shift to UTC (Coordinated Universal Time)
SNTP time server 2 (optional)
You can use this parameter to enter the IP address of the second time
server (optional).
9.5.1 Time synchronization via PTP
You can use this parameter to activate time synchronization via a PTP time
server.
PTP hops
You can use this parameter to enter the number of network sections be-
tween master and slave. You can set up to 16 hops.
