DTU.SetDateAndTime (FB prefix: sdt)

This function block of the CAA_DTUtil.library sets the realtime clock. The current local time is passed in the parameter „dtDateAndTime“.

提示！

If the time is within the not-unique interval shortly after the switch to standard (winter) time, standard time will be assumed. This case occurs in the Central European countries, if for example on the last Sunday of October the time is set at 2:30 a.m.. Here it is not clear, whether 2:30 a.m. is still summer time or already standard (winter) time. In this case the module assumes standard (winter) time.

Input:

xExecute	BOOL	A rising edge will start the action
dtDateAndTime	DATE_AND_TIME	Current time

Output:

xDone	BOOL	Action terminated successfully
xBusy	BOOL	Module is active
xError	BOOL	Error occurred
eError	WORD	Error ID for diagnosis (see DTU.ERROR)
