CD522SsiCnt_PLUS (FB)

FUNCTION_BLOCK CD522SsiCnt_PLUS EXTENDS AbbLConCA

Function block to access all IO-Values for the SSI of CD522. With additional ResetSSI signal input.

If the SSI Encoder has differential signals adjust parameter “Input level FCx” to “differential”.

Also adjust the SSI frequency, SSI resolution in Bit and SSI polling time. This FB is valid to be used with mode 14

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	ChnNum	WORD	0	0 or 1, counter 0 or counter 1 is 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
	EdgeTouch	BOOL	FALSE	Select (TRUE) positive or (FALSE) negative edge for touch
	ResetSsi	BOOL	FALSE	Reset signal for SSI encoder. Sets an output signal on CD522 for SSI encoder reset input. (ChnNum 0: on CD522 output C7 is set / ChnNum 1: on CD522 output C15 is set)
	EnGray	BOOL	FALSE	If (TRUE), Actual value will be calculated from gray code to binary code
	EnBcd	BOOL	FALSE	If (TRUE), Actual value will be calculated from bcd code to binary code
	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
	Act	DWORD	0	32 bit actual counter value
	CntTouch	DWORD	0	32 bit touch counter value
	RdyTouch	BOOL	FALSE	Set (TRUE) when new touch value is available
