Get present system diagnosis

This function block provides diagnosis information which slaves are configured and which slaves are in active data exchange mode. Type of requested information can be selected via SlaveStateType. Information about slaves signaling active diagnosis is not supported for this function block. Please use standard diagnosis functions instead, which are provided as device diagnosis.

InOut:

Scope	Name	Type	Initial	Comment	Inherited from
Input	Enable	BOOL	FALSE	A rising edge (Enable = TRUE) starts the operation, the output Busy goes to TRUE. All other inputs are read and considered continuously. A falling edge (Enable = FALSE) aborts the operation. During Aborting the Busy is still TRUE. Afterward all outputs are reset.	AbbLConA
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.	AbbLConA
	Busy	BOOL	FALSE	Operation is running (while outputs Done and Error are FALSE)	AbbLConA
	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.	AbbLConA
Input	Device	AC500_IoDrvCm592Profibus.IDeviceCM592Profibus	0	Reference to coupler device instance
	SlaveStateType	SlaveStateBitFieldType	SlaveStateBitFieldType.CM592_PROFIBUS_SLAVE_STATE_TYPE_CFG	Type of slave state bit field (configured / data exchange)
Output	ErrorID	ERROR_ID	ERROR_ID.NO_ERROR	Error code that describes the occured error
	AddErrorID	UDINT	CM592Const.CM592_ADD_ERROR_NONE	Additional error info, in case ErrorID shows “REQUEST_FAILED”
	SlaveStates	CM592SlaveStates		Slave state array of booleans - to show system diagnosis
