DT_TO_SYSTEMTIME

DT_TO_SYSTEMTIME 1:

The "DT_TO_SYSTEMTIME" function allows a PLC variable in DATE_AND_TIME format (DT) to be converted to a Windows system time structure. The system time has a resolution of 1ms, while the resolution of DATE_AND_TIME is 1s. The "wMilliseconds" variable in the system time structure therefore always returns the value zero.

FUNCTION DT_TO_SYSTEMTIME : TIMESTRUCT

TIMESTRUCT 

VAR_INPUT
    DTIN        : DT;
END_VAR

DTIN:: The date and time to be converted, in DATE_AND_TIME format.

 

Example of a call in FBD:

    SystemTimeStruct  :TIMESTRUCT;
END_VAR
