IS_VALID_DT_INT

Check whether DATE_AND_TIME is valid

IS_VALID_DT checks whether the combination of INT values for year, month, day, hour, minute, second, and millisecond is a valid date and time value. The Boolean output flag is set if the date and time value is valid.

Parameters

Input

YEAR (INT): 1st input: year
MONTH (INT): 2nd input: month
DAY (INT): 3rd input: day
HOUR (INT): 4th input: hour
MINUTE (INT): 5th input: minute
SECOND (INT): 6th input: second
MILLISECOND (INT): 7th input: millisecond

Output

VAR_OUT (BOOL): set to TRUE if the resulting date and time value is valid

Example

POU header

All input and output variables used for programming this function have been declared in the POU header. The same POU header is used for all programming languages.

	VAR
		YEAR_value: INT:=2011;
		MONTH_value: INT:=12;
		DAY_value: INT:=24;
		HOUR_value: INT:=18;
		MINUTE_value: INT:=29;
		SECOND_value: INT:=59;
		MILLISECOND_value: INT:=0;
		VALID: BOOL:=FALSE;
