6.2 PowerlinkConnectionPointType

6.2.1 General

The PowerlinkConnectionPointType is an abstract Object Type that defines the POWERLINK Objects, which are common for both POWERLINK Managing Node and POWERLINK Controlled Node.

Figure 16 shows a part of the PowerlinkConnectionPointType. The Object ParameterSet contains the POWERLINK Objects, modelled as defined in 5.2. In addition to these Variables, this specification defines a list of Methods (components of the Object MethodSet).

As defined by the concepts of OPC 10000-100 the Parameters (Variables) of the ParameterSet and Methods of the MethodSet are organised in FunctionalGroups where they are referenced by Organize-References. This concept allows splitting the Parameters into different categories, and at the same time, all Parameters are accessible under ParameterSet.

6.2.2 PowerlinkConnectionPointType Definition

The PowerlinkConnectionPointType is formally defined in Table 17.

6.2.3 Method ReadByIndex

The Method ReadByIndex reads the value of a POWERLINK Object addressed by Index and Sub-Index.

Signature

	ReadByIndex (
		[in]	UInt16		Index
		[in]	Byte			SubIndex
		[out]	BaseDataType	Data
		[out]	UInt32		PowerlinkAbortCode
		);
	

Method Result Codes

6.2.4 Method WriteByIndex

The Method WriteByIndex can be used to access the POWERLINK Object Dictionary by Index and Sub-Index to write values of POWERLINK Objects.

Signature

	WriteByIndex (
		[in]	UInt16		Index
		[in]	Byte			SubIndex
		[in]	BaseDataType	Data
		[out]	UInt32		PowerlinkAbortCode
		);
