CD522FreqScan (FB)

FUNCTION_BLOCK CD522FreqScan EXTENDS AbbLConCA

Function block to access all IO-Values for the frequency measurement of CD522. This FB is valid to be used with mode 15. Maximum input frequency 5 kHz.

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, use of counter 0 or counter 1 (Input Z0 or Z1)
	EnCnt	BOOL	FALSE	Enable (TRUE) or disable (FALSE) the function of the module
	En0	BOOL	FALSE	Enables low pulse for measurement
	En1	BOOL	FALSE	Enables high pulse for measurement
	EnFreq	BOOL	FALSE	Enables frequency (TRUE) / time measurement mode (FALSE). Result in Freq/Rpm (TRUE) or Dur (FALSE). Maximum input frequency 5 kHz
	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
	New	BOOL	FALSE	New value available
	Dur	DWORD	0	Duration (Time in micro seconds)
	Freq	WORD	0	Frequency
	Rpm	DWORD	0	Rotation per minute
