Block Structure

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

Operation

When this block has the TRUE value in EN, it interprets the date and time value in EPOCH format and converts it to values that are easy to interpret.

When EN has a FALSE value, outputs remain unchanged.

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

Example in Ladder

EPOCH_TO_DATETIME_example01

The example above converts date and time in EPOCH format (DWORD) to easy-to-read values. 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;

min : BYTE;

hour : BYTE;

day : BYTE;

month : BYTE;

year : WORD;

wDay : BYTE;

epoch : DWORD := 1717200000;

END_VAR

done := FB_EPOCH_TO_DATETIME(EN:=enable, Epoch:= epoch, Second=> sec, Minute=>min, Hour=>hour, Day=>day, Month=>month, Year=>year, WeekDay=>wDay);
