CI504PnioComRec (FB)

FUNCTION_BLOCK CI504PnioComRec EXTENDS AbbLCon3

implements receiving data via serial interface of a CI504

InOut:

Scope	Name	Type	Initial	Comment	Inherited from
Input	Enable	BOOL	FALSE	A rising edge (Enable = TRUE) starts a single operation, the output Busy goes to TRUE. All other inputs are read and considered continuously. A falling edge (Enable = FALSE) aborts the operation, if BUSY=TRUE (Note: During Aborting the Busy is still TRUE). Afterwards all outputs will be reset. For executing another operation the Enable input needs to be retriggered by another rising edge!	AbbLCon3
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 Enable is set to FALSE.	AbbLCon3
	Busy	BOOL	FALSE	Operation is running (while outputs Done and Error are FALSE)	AbbLCon3
	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 Enable is set to FALSE. The output ErrorID gives more details about the error.	AbbLCon3
Input	Device	AC500_IoDrvCM579Profinet.IDeviceCM579Profinet		instance of CM579-PNIO device
	DevName	AC500_CM579Profinet.CM579PnioDevName		name of device which the data object is to be received from (e.g. ‘ci504-pn-01’ )
	Com	USINT		serial interface number (COM 1, COM 2, COM 3)
	InFlags	WORD		input flags of the device in IO image
Output	ErrorID	ERROR_ID		ID of execution error
	StatusCode	UDINT		PROFINET status code of read service according to PROFINET specification
	AddVal1	UINT		additional value 1 returned from PROFINET IO Device
	AddVal2	UINT		additional value 2 returned from PROFINET IO Device
	Msg	CI504PnioComMessageArray		array of messages
	NumMsg	USINT		number of messages received and stored in Msg
	OutFlags	WORD		output flags of the device in IO image
