CD522TwoWordCounters (FB)

FUNCTION_BLOCK CD522TwoWordCounters EXTENDS AbbLConCA

Function block to access all IO-Values for the 16-Bit-Counter of CD522. This FB is valid to be used with mode 3 and 4

InOut:

Scope	Name	Type	Initial	Comment	Inherited from
Input	Enable	BOOL	FALSE	A rising edge (Enable = TRUE) starts the operation, the output Busy goes to TRUE. All other inputs are read and considered continuously. A falling edge (Enable = FALSE) aborts the operation. During Aborting the Busy is still TRUE. Afterward all outputs are reset.	AbbLConCA
Output	Busy	BOOL	FALSE	Operation is running (while output Error is FALSE)	AbbLConCA
	Error	BOOL	FALSE	Operation is stopped with error (while output Busy is FALSE). This output is TRUE for at least one cycle or until Enable is set to FALSE. The output ErrorID gives more details about the error.	AbbLConCA
Input	CntNum	WORD	0	0 or 1, declares if counter 0 or counter 1 is to be used
	EnCnt	BOOL	FALSE	Enable (TRUE) or disable (FALSE) the counter function of the module
	EnTouch	BOOL	FALSE	Enable (TRUE) or disable (FALSE) the touch function of the module. Touch inputs are I3 (Counter0) and I11 (Counter1). In “CD522 Parameters” you have to configure these inputs as Value = “TOUCH”
	EdgeTouch	BOOL	FALSE	Select (TRUE) positive or (FALSE) negative edge for touch
	Ud1	BOOL	FALSE	Up (FALSE) or down (TRUE) counting mode
	Ud2	BOOL	FALSE	Up (FALSE) or down (TRUE) counting mode
	Reset1	BOOL	FALSE	Reset current counter value1
	Reset2	BOOL	FALSE	Reset current counter value2
	AdrIn	POINTER TO WORD	0	Address of process image input. See ../Structs/CD522In for more information about structure
	AdrOut	POINTER TO WORD	0	Address of process image output. See ../Structs/CD522Out for more information about structure
Output	ErrorID	ERROR_ID	ERROR_ID.NO_ERROR	Error code description
	Act1	INT	0	16 bit current counter value (Input A)
	Act2	INT	0	16 bit current counter value (Input B)
	CntTouch1	INT	0	16 bit touch value counter
	CntTouch2	INT	0	16 bit touch value counter
	Ofl1	BOOL	FALSE	Overflow on counter (Input A)
	Ofl2	BOOL	FALSE	Overflow on counter (Input B)
	RdyTouch	BOOL	FALSE	Set to TRUE when new touch value is available. To delete RdyTouch set EnTouch to FALSE. To allow a new Touch, set EnTouch to TRUE again
	ResetIn1	BOOL	FALSE	Reset 1 signal detected
	ResetIn2	BOOL	FALSE	Reset 2 signal detected
