EcatState (FB)

FUNCTION_BLOCK EcatState EXTENDS AC500_EcatBase.EcmETrigExt

Function block to get coupler’s present state

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	Device	IDeviceCM579EtherCAT		Coupler device	EcmETrigExt
Output	ErrorID	ERROR_ID	ERROR_ID.NO_ERROR	Error code describing error condition (ERROR_ID located in AC500_EcatBase)	EcmETrigExt
	AddErrNo	UDINT	0	Addition error code for detailed error description, will be set if ErrorID = ERROR_ID.ADDITIONAL_ERROR_INFO (16#31). Explanation of error codes can be found in Hilscher documentation: https://kb.hilscher.com/display/ECM3V0/EtherCAT+Master+V4, chapter 5
	CommState	UDINT	0	Communication state
	CommErno	UDINT	0	Communication error
	NumErr	BYTE	0	Number of errors occured since power up
