Ntp Client - Siemens SIMATIC NET SCALANCE W780 Series Configuration Manual

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. You configure the daylight saving time switchover on
the pages "System > System Time > DST Overview" and "System > System Time > DST
Configuration". 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:
– Poll
– Listen
4. In the "Poll Interval[s]" input box, enter the time in seconds after which a new time query
is sent to the time server.
5. In the "SNTP Server Address" input box, enter the IP address or the FQDN of the SNTP
server whose frames will be used to synchronize the time of day.
6. Click the "Create" button.
A new row is inserted in the table for the SNTP server.
7. In the "SNTP Server Port" column, enter the port via which the SNTP server is available.
The port can only be modified if the IPv4 address or the FQDN name of the SNTP server
is entered.
8. Click the "Set Values" button to transfer your changes to the device.
