HaModPid (FB)

FUNCTION_BLOCK HaModPid

Function block HaModPid is a standard PID with automatic data synchronization in a high availability system Only internal variables and outputs are synchronized. Input variables and parameters are not synchronized. If needed, use HaModDataSync to achieve the same.

InOut:

Scope	Name	Type	Initial	Comment
Input	Actual	REAL	0	1:Actual value, process variable
	SetPoint	REAL	0	2:Desired value, set point
	Kp	REAL	0	3:Proportionality const coefficient , unity gain of the P-part (P ).
	Tn	REAL	0	4:Reset time (I) in sec
	Tv	REAL	0	5:Rate time, derivative time (D) in sec
	YManual	REAL	0	6:Y is set to this value as long as Manual=TRUE
	YOffset	REAL	0	7:Offset for manipulated variable
	YMin	REAL	0	8:Minimum value for manipulated variable
	YMax	REAL	0	9:Maximum value for manipulated variable
	Manual	BOOL	FALSE	10:TRUE: manual: Y is not influenced by controller, FALSE: controller determines Y
	Reset	BOOL	FALSE	11:Reset: set Y output to YOffset and reset integral part
Output	Y	REAL	0	1: Manipulated variable, set value
	LimitsActive	BOOL	FALSE	2:True set value would exceed limits YMin, YMax
	Overflow	BOOL	FALSE	3:Overflow in integral part
