CM579PnioGetDevState (FB)

FUNCTION_BLOCK CM579PnioGetDevState EXTENDS CM579PnioBase

funktion block to read the current state of specified PROFINET IO Device

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.	AbbETrig2
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	AbbETrig2
	Busy	BOOL	FALSE	Operation is running (while outputs Done and Error are FALSE)	AbbETrig2
	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.	AbbETrig2
Input	Device	AC500_IoDrvCM579Profinet.IDeviceCM579Profinet		instance of CM579-PNIO device	CM579PnioBase
Output	ErrorID	ERROR_ID		error code that describes occurred error	CM579PnioBase
	AddErrorID	UDINT		additional description of error, meaning depends on value of output ErrorID	CM579PnioBase
Input	DevName	CM579PnioDevName		name of device (e.g. ‘ci501-pn-01’ )
Output	MacAddr	ARRAY [1..6] OF BYTE		MAC address of device
	IpAddr	UDINT		IP address of device
	VendorID	UINT		Vendor ID of device
	DeviceID	UINT		Device ID of device
	Active	BOOL		state of connection between controller and device
	DiagFlags	DWORD		diagnosis flags, see CM579PNIO_DEVICE_DIAGFLAGS_… in CM579PnioConst
