Y_YA_Scaler

This function block performs the calculation y:= mx + b.

Parameters:

*	Parameter	Data Type	Description	Default
VAR_INPUT
B	Enable	BOOL	The function will continue to execute every scan while Enable is held high and there are no errors.	FALSE
V	Input	LREAL	The x variable of y:=mx + b.	LREAL#0.0
V	CalX1	LREAL	Datapoint specifying a line along which data is to be scaled.	LREAL#0.0
V	CalY1	LREAL	Datapoint specifying a line along which data is to be scaled.	LREAL#0.0
V	CalX2	LREAL	Datapoint specifying a line along which data is to be scaled.	LREAL#0.0
V	CalY2	LREAL	Datapoint specifying a line along which data is to be scaled.	LREAL#0.0
VAR_OUTPUT
B	Valid	BOOL	Indicates that the function is operating normally and the outputs of the function are valid.
V	Output	LREAL	The result of the calculation y:=mx + b.
V	m	LREAL	The calculated slope of the line.
V	b	LREAL	The calculated intercept of the line.
B	Error	BOOL	Set high if an error has occurred during the execution of the function block. This output is cleared when 'Execute' or 'Enable' goes low.
B	ErrorID	UINT	If Error is true, this output provides the Error ID. This output is reset when 'Execute' or 'Enable' goes low.

m is determined by the slope of a line specified by Cal_X1, Cal_Y1, Cal_X2, Cal_Y2.
x is the 'Input'
b is determined by calculating the Y intercept of the line.
