EcatCoeRead (FB)

FUNCTION_BLOCK EcatCoeRead EXTENDS CM579EcatCoeRead

Function block to read SDO/CoE object data

InOut:

Scope	Name	Type	Initial	Comment	Inherited from
Input	Execute	BOOL	FALSE	A rising edge starts a single operation, the output Busy goes to TRUE. In the first cycle all other inputs are read and stored, afterwards they are ignored. A falling edge does not stop the operation. After Done = TRUE or Error = TRUE and Execute = FALSE all outputs will be reset. For executing another operation the Execute input needs to be retriggered by another rising edge!	AbbETrig3
Output	Done	BOOL	FALSE	Operation is completed without error (while outputs Busy and Error are FALSE). This output is TRUE for at least one cycle or until Execute is set to FALSE	AbbETrig3
	Busy	BOOL	FALSE	Operation is running (while outputs Done and Error are FALSE)	AbbETrig3
	Error	BOOL	FALSE	Operation is stopped with error (while outputs Busy and Done are FALSE). This output is TRUE for at least one cycle or until Execute is set to FALSE. The output ErrorID gives more details about the error.	AbbETrig3
Input	Device	IDeviceCM579EtherCAT		CM579-ECAT coupler device	CM579EcatBase
Output	ErrorID	ERROR_ID		Error code describing error condition	CM579EcatBase
	AddErrNo	UDINT		Additional error code for detailed error description, will be set if ErrorID = ERROR_ID.ADDITIONAL_ERROR_INFO.	CM579EcatBase
Input	Node	UINT		NODE ID	CM579EcatCoeRead
	Index	UINT		Index of the SDO object	CM579EcatCoeRead
	SubIndex	BYTE		Subindex of the SDO object	CM579EcatCoeRead
	Len	UINT		Max length (in bytes) of data to be read	CM579EcatCoeRead
	Data	POINTER TO BYTE		Where to write the read SDO data	CM579EcatCoeRead
	Timeout	UINT		Timeout in milliseconds	CM579EcatCoeRead
Output	NumBytes	UDINT		Length in bytes of SDO data read	CM579EcatCoeRead
