INTEGRAL (FB)¶

FUNCTION_BLOCK INTEGRAL

determines approximately the integral over time.

Example: Function block in FBD

InOut:

Scope	Name	Type	Initial	Comment
Input	IN	REAL		Input value
	TM	DWORD		Time since last call in msec
	RESET	BOOL		TRUE: OUT is set to zero and OVERFLOW to FALSE
Output	OUT	REAL		Value of the integral. This is done by summing all part integrals IN * TM
	OVERFLOW	BOOL	FALSE	TRUE: The value of OUT is out of range of REAL variables. he function is blocked till it is new initialised by input RESET.
