EcatSlvGetState (FB)

FUNCTION_BLOCK EcatSlvGetState EXTENDS AC500_EcatBase.EcmETrigExt

Function block reads the state in the EtherCAT State machine of a selected EtherCAT slave

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
Input	Node	UINT	0	Node ID
Output	AddErrNo	UDINT	0	Additional 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
	State	teEcatDevState	teEcatDevState.NONE	Current state of the slave EtherCAT state machine
	TargetState	teEcatDevState	teEcatDevState.NONE	Target state of the last requested state change
	ActivateErr	UDINT	0	Activation error of the last requested state change
