Y_MA_CalcCircleCenter

Given two points on a circle, radius, direction , and path, this FB calculates the center of the circle.

Parameters:

*	Parameter	Data Type	Description	Default
VAR_INPUT
B	Enable	BOOL	The function block will continue to execute every scan while Enable is TRUE and there are no errors.	FALSE
V	X1	LREAL	X coordinate of starting point.	LREAL#0.0
V	Y1	LREAL	Y coordinate of starting point.	LREAL#0.0
V	X2	LREAL	X coordinate of ending point.	LREAL#0.0
V	Y2	LREAL	Y coordinate of ending point.	LREAL#0.0
V	Radius	LREAL	Radius of the circle.	LREAL#0.0
V	PathChoice	MC_CirclePathChoice	If the path length is larger than 180 degrees, use MC_CirclePathChoice#Longest. If the path length is 180 degrees or less, use MC_CirclePathChoice#Shortest.	MC_CirclePathChoice#ClockWise
V	Direction	MC_CirclePathChoice	If the circle path travels clockwise use MC_CirclePathChoice#Clockwise. Otherwise if the circle path travels counterclockwise use MC_CirclePathChoice#CounterClockWise.	MC_CirclePathChoice#ClockWise
VAR_OUTPUT
B	Valid	BOOL	The Valid output indicates that the function block is operating normally and the outputs of the function block are valid.
B	Error	BOOL	The Error output is set to TRUE if an error has occurred during the operation of the function block. The output is cleared when the Execute or Enable input becomes FALSE.
E	ErrorID	UINT	The ErrorID output provides the identifier of the error when there is an active error in the function block execution. The output is cleared when the Execute or Enable input becomes FALSE.
V	CenterX	LREAL	X coordinate of the center of the circle
V	CenterY	LREAL	Y coordinate of the center of the circle
