CM579EcatSlvGetMDPModules (FB)

FUNCTION_BLOCK CM579EcatSlvGetMDPModules EXTENDS CM579EcatBase

Function block to read slave diagnosis data Function block to get a list of MDP (Modular Device Profile) modules that are connected to a slave device. This is supported by CI512 2.1.8 and above.

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	Node	UINT	0	Node ID
	StrDataOut	POINTER TO DWORD		Array of DWORDs to be provided by caller, will be filled by FB
	uiLength	UINT		Element count of data array provided with StrDataOut
Output	uiMaxNumModules	UINT		maximum number of supported modules
