5.1 Settings for the service technician
The internal clocks of all units, which are connected to the WIB8000 by the Stulz bus can be synchronized.
In case of an indirect connection (e.g. connection of a C7000AT to a C7000IOC by the IO bus) the C7000AT
system clock is not synchronized.
The synchronization of the system clocks of all connected units enables the comprehension of the chronolog-
ical context of the unit/controller eventlogs and simplifies the elimination of complex error causes.
The WIB can update its own system clock by sending requests to a NTP server (SNTP - Simple Network Time
Protocol).
The synchronization of the connected controllers as the update of the WIB system clock by SNTP request
via network, is done at once after the activation of the corresponding function and then with the cycle of the
adjusted interval.
The following parameters have to be adjusted. A valid NTP server address (server name or IP address), two
time intervals (hourly/daily/weekly) and the relative time difference of the local time to UTC time.
CET
+1:00
CEST
+2:00
Sydney
+10:00
Canada
-3:30
USA, Frederick
-5:00
On one hand a time interval can be adjusted, in which the
WIB updates its system clock, on the other hand you can
adjust a time interval, in which the WIB synchronizes the
system clocks of all connected controllers with the WIB
clock.
The UTC time is also called "coordinated universal time"
and is edited by the NTP server.
Examples:
First you should set the local time. This can be done in the menu "time". The settings done are transmitted to
the system and will then be effective by clicking on the "Send" button. Clicking on the "Reset" button resets
the parameters to the default settings. This is also valid for all following menus.
Before setting the time you should connect the battery on the board (
wise your settings will get lost with a power failure.
