If the PC time and date are to be sent as telegrams to the bus (EIB: EIS3 and EIS4), the time available via the system port can be used. This time is localized and also includes the summer/winter time switch.
The internal clock of the PC can be connected to a DCF receiver for PC (approx. 50 Euro) or a time server on the Internet

Name “Date/Time”, Type “Time”, Port “SYS”, Address “Time”, Group “System”
- To create a data point query:
Name “system_1min”, time interval 00:01:00
and assign it to the data point
- Create the two data points Zeit_auf_EIB and Datum_auf_EIB and calculate the nominalvalue of the data points in each case.
In the calculation, only the current value of the Date/Time data point is assigned to the Result: Result = @(Date/Time). ActualValue
