PnioCntrlRead (FB)

FUNCTION_BLOCK PnioCntrlRead EXTENDS AbbETrig

Read specific data from a device (RPC) through channel mailbox. No automatical sequenced packets, only single packets.

InOut:

Scope	Name	Type	Initial	Comment	Inherited from
Input	Execute	BOOL	FALSE	A rising edge starts the 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.	AbbETrig
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	AbbETrig
	Busy	BOOL	FALSE	Operation is running (while outputs Done and Error are FALSE)	AbbETrig
	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.	AbbETrig
Input	Slot	BYTE	0	Slot number of assigned coupler
	DevName	STRING(PNIOCNTRL_GLOBALS.PNIO_DEVNAME_LEN)	‘’	Name of the device (Station Name, e.g. ‘ci501-pn-03’ )
	DevApi	DWORD	0	API
	DevSlot	WORD	0	Slot
	DevSubSlot	WORD	0	Sub slot
	DevIdx	WORD	0	Index
	Data	POINTER TO BYTE	0	Pointer to put data read to (via ADR operator)
	DataMax	WORD	0	Max length of data
Output	ErrorID	ERROR_ID	ERROR_ID.NO_ERROR	Error code description
	AddErrNo	UDINT	16#0	additional internal error code
	Status	DWORD	0	PNIO code
	AddVal1	WORD	0	Additional value 1
	AddVal2	WORD	0	Additional value 2
	DataLen	WORD	0	Number of bytes read to ADR(Data)
