OPC HDA data object
The opc.hda.Data object stores and presents information retrieved from an OPC historical data access server. The OPC HDA data object allows you to store and process data retrieved from an OPC HDA server, and convert that data into MATLAB® data types that can be operated on further.
You construct OPC HDA data objects using the various methods to read an OPC HDA client object.
