Introduction to OPC HDA Data Objects
All data returned from OPC HDA servers can be stored in MATLAB® as an OPC HDA data object.
OPC HDA data read operations can produce a large amount of data returned to MATLAB.
Manipulate Data Using OPC Toolbox HDA Objects
OPC HDA data objects provide initial data storage, visualization, and manipulation functions for you to work with OPC historical data in MATLAB.
Retrieve Large Historical Data Sets
Retrieve very large data sets from OPC historical data access servers.
