Block Structure

Variable Type	Name	Data Type	Description
VAR_INPUT	EN	BOOL	Block enabling
	Second	BYTE	Seconds
	Minute	BYTE	Minutes
	Hour	BYTE	Hours
	Day	BYTE	Days
	Month	BYTE	Months
	Year	WORD	Years
VAR_OUTPUT	ENO	BOOL	End of operation
VAR_OUTPUT	Result	DWORD	Value in EPOCH

Operation

When this block has a TRUE value in EN, it interprets the date and time values and converts them to EPOCH, storing in Result.

When EN has FALSE value, Result remains unchanged.

The ENO value forwards to the next Ladder block the EN value after the operation is completed.

Example in Ladder

DATETIME_TO_EPOCH_example01

The example above converts the date and time to EPOCH (DWORD) format, storing the final result in RESULT. The block ends with success, and the ENO output is activated.

Example in ST

The example below displays instructions for applying the example above in ST language.

VAR

enable : BOOL := 1;

done : BOOL;

sec : BYTE := 30;

min : BYTE := 30;

hour : BYTE := 12;

day : BYTE := 15;

month : BYTE := 6;

year : WORD := 2030;

epoch : DWORD;

END_VAR

done := FB_DATETIME_TO_EPOCH(EN:=enable, Second:= sec, Minute:=min, Hour:=hour, Day:=day, Month:=month, Year:=year, Result=> epoch);
