FUNCTION_BLOCK PUBLIC CM592DPV1Masc1Read EXTENDS CM592BaseCommonReq

DPV1 service MSAC1_Read - read data from a DPV1 capable slave

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	IDeviceCM592Profibus	0	Instance of CM592 profibus device	CM592BaseCommonReq
Output	ErrorID	ERROR_ID	ERROR_ID.NO_ERROR	Error code that describes the occured error	CM592BaseCommonReq
	AddErrorID	UDINT	CM592Const.CM592_ADD_ERROR_NONE	Additional error info, in case ErrorID shows “REQUEST_FAILED”	CM592BaseCommonReq
Input	SlaveAddr	USINT	0	Address of PROFIBUS slave device (0 - 125)
	SlaveSlot	USINT	0	Slot number at slave (0 - 254)
	SlaveIndex	USINT	0	Index within slot number at slave (0 - 254 or 255 to access LR state machine, e.g. to access I&M data)
	DataLen	USINT	0	Length of data to be read in number of bytes
	Data	POINTER TO BYTE	0	Address of buffer where to put received DPV1 data into
Output	ErrNo1	USINT	0	PROFIBUS DPV1 specific error code sent by slave
	ErrNo2	USINT	0	PROFIBUS DPV1 specific error code sent by slave
	DataLenRead	USINT	0	Length of data read
