Time Client Type
You can choose from four different protocol types here:
● SNTP Poll
If you choose this protocol type, you have to make further settings:
Timezone offset, Time server, Init poll interval, Poll interval.
● SNTP Listen
No further settings are possible in this mode.
● SIMATIC Time
If you use the SIMATIC time transmitter, you do not need to make any further settings.
● Manual
If you have selected this protocol type, the "Set Time" input box is displayed. Enter the
current values for day, month, year and time in the "Set Time" input box.
When turning off or resetting the device, this information is lost and must be set again.
● NTP
With this setting, time synchronization uses the Network Time Protocol according to RFC
958.
The additional settings are described below.
Time Server
Enter the Internet address of the server with which the system time will be synchronized.
Port
Enter the number of the UDP port being used. As default, the SNTP protocol uses UDP port
123.
Init Poll Interval
Here, you can enter the interval at which the X-200 IE switch repeats the initial poll for the
system time if this was not successful the first time.
Range of values: 1000 - 100000
Poll Interval
Once the system time has been adopted the first time from the time server, it is updated
cyclically with renewed polls to the time server. Here, you specify how often the updates take
place.
Range of values: 10 - 100000
