Data Manipulation and Display
Use HDA data objects to format and convert OPC HDA data and its
display
All data returned from an OPC HDA server is stored in MATLAB® as an OPC HDA data object. The HDA data object allows for convenient data storage, manipulation, and visualization. The data elements themselves are represented by one or more value, quality, and timestamp values, all associated with an item ID.
