[Extension()] [ElementsNotNull()] [NotNull()] public: static array<UAAttributeDataResult^>^ ReadMultiple( IEasyUAClient^ client, UAEndpointDescriptor^ endpointDescriptor, UANodeDescriptor^ nodeDescriptor, array<UAAttributeId>^ attributeIdArray )
Parameters
- client
- The client object that will perform the operation.
- endpointDescriptor
- Endpoint descriptor. Identifies the OPC-UA server.
- nodeDescriptor
- Node descriptor. Identifies the node in OPC server's address space.
- attributeIdArray
- Array of UAAttributeId. Array of attribute IDs specifying what to read from an OPC-UA server.
Return Value
Array of OpcLabs.EasyOpc.UA.OperationModel.UAAttributeDataResult. Returns an array of attribute data objects. Each object stores the value of an attribute, together with status code and timestamps. The indices of elements in the output array are the same as those in the input array, attributeIdArray.
