CM579EcatBusDiag (FB)

FUNCTION_BLOCK CM579EcatBusDiag EXTENDS CM579EcatBase

Function block to read bus diagnosis data

InOut:

Scope	Name	Type	Initial	Comment	Inherited from
Input	Execute	BOOL	FALSE	A rising edge starts a single 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. For executing another operation the Execute input needs to be retriggered by another rising edge!	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	IDeviceCM579EtherCAT		CM579-ECAT coupler device	CM579EcatBase
Output	ErrorID	ERROR_ID		Error code describing error condition	CM579EcatBase
	AddErrNo	UDINT		Additional error code for detailed error description, will be set if ErrorID = ERROR_ID.ADDITIONAL_ERROR_INFO.	CM579EcatBase
Input	Len	UINT	0	Element count of array SlvState
	SlvState	POINTER TO teEcatDevState	0	Pointer to an array that will be filled with slave states
Output	NumActSlv	UDINT	0	Number of active slaves
	NumConfSlv	UDINT	0	Number of configured slaves
	NumFaultSlv	UDINT	0	Number of faulty slaves
	CurrentState	teEcatDevState		Current state of master
	TargetState	teEcatDevState		Target state of master
	StopReason	UDINT		0: State change in progress/successful, otherwise: Last state change has been aborted
	StatusFlags	UDINT		Master status flags: Bit 0: At least one mandatory slave not connected, Bit 1: DC slaves are not syncing their sys time, Bit 2: At least one mandatory slave not in OP
	CommState	UDINT	0	Communication state
	CommErno	UDINT	0	Communication error
	PDErrInCnt	UDINT	0	Number of input process data handshake errors
	PDErrOutCnt	UDINT	0	Number of output process data handshake errors
