CM579PnioGetCntrlState (FB)

FUNCTION_BLOCK CM579PnioGetCntrlState EXTENDS AC500_StateMachine.AbbETrig3

function block to read the current state of specified Communication Module CM579-PNIO

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.	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	AC500_IoDrvCM579Profinet.IDeviceCM579Profinet		instance of CM579-PNIO device
Output	ErrorID	ERROR_ID		error code that describes the occured error
	AddErrorID	UDINT		additional description of error, meaning depends on value of output ErrorID
	CommState	CM579PnioCommState		communication state of PROFINET IO Controller
	CommError	UDINT		communication error of PROFINET IO Controller
	NumErrors	UDINT		number of errors occured since power up
	DeviceState	CM579PnioDeviceState		PROFINET IO Controller exchanges cyclic data with ALL configured PROFINET IO Devices
	NumDevicesConfig	UDINT		number of configured PROFINET IO Devices
	NumDevicesActive	UDINT		number of active PROFINET IO Devices
	NumDevicesDiag	UDINT		number of configured PROFINET IO Devices with diagnosis
