● SNTP Server Port
Enter the port of the SNTP server.
The following ports are possible:
– 123 (standard port)
– 1025 to 36564
● Poll Interval[s]
Here, enter the interval between two-time queries. In this box, you enter the query interval
in seconds. Possible values are 16 to 16284 seconds.
Procedure
1. Click the "SNTP Client" check box to enable the automatic time setting.
2. In the "Time Zone" input box, enter the local time difference to world time (UTC). The
input format is "+/-HH:MM" (for example +02:00 for CEST), because the SNTP server
always sends the UTC time. This time is then recalculated and displayed as the local time
based on the specified time zone. On the device itself, there is no changeover from the
daylight saving to standard time. You also need to take this into account when completing
the "Time Zone" input box.
3. Select one of the following options from the "SNTP Mode" drop-down list:
– Listen
– Poll
4. In the "SNTP Server Address" input box, enter the IPv4 address of the SNTP server
whose frames will be used to synchronize the time of day.
5. In the "SNTP Server Port" input box, enter the port via which the SNTP server is
available. The port can only be modified if the IPv4 address of the SNTP server is
entered.
6. In the "Poll Interval[s]" input box, enter the time in seconds after which a new time query
is sent to the time server.
7. Click the "Set Values" button to transfer your changes to the device.
