IoCnt (FB)

FUNCTION_BLOCK IoCnt EXTENDS AbbLConCA

Handle fast counters on S500 IO-modules

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	BusType	BYTE	0	BUS : 0 = default , 1 = CAN
	Mode	BYTE	0	FC Mode
	AdrInputs	POINTER TO BYTE	0	Pointer to Inputs
	AdrOutputs	POINTER TO BYTE	0	Pointer to Outputs
	EnVisu	BOOL	FALSE	Enable settings in visu
Inout	En1	BOOL		Enable counting counter 1
	UD1	BOOL		Up / down counter 1
	EnOut1	BOOL		Enable output counter 1 in user program
	Set1	BOOL		Set start value counter 1
	Start1	DWORD		Start value counter 1
	End1	DWORD		End value counter 1
	En2	BOOL		Enable counting counter 2
	UD2	BOOL		Up / down counter 2
	EnOut2	BOOL		Enable output counter 2 in user program
	Set2	BOOL		Set start value counter 2
	Start2	DWORD		Start value counter 2
	End2	DWORD		End value counter 2
Output	ErrorID	ERROR_ID	ERROR_ID.NO_ERROR	Error code describing error condition
	CntState	WORD	0	Counter mode
	CF1	BOOL	FALSE	Carry Flag 1 := TRUE -> end value reached
	Act1	DWORD	0	Actual value counter 1
	CF2	BOOL	FALSE	Carry Flag 2 := TRUE -> end value reached
	Act2	DWORD	0	Actual value counter 2
