Graphical Display of OPC Data

The new trend function provides a graphical display of live OPC data for an OPC group object. You can now watch live data stream to a MATLAB figure window. The trend functionality is independent of OPC logging tasks. More information is available on the trend reference page.

Time Series Objects Now Supported

OPC Toolbox software now supports time series objects, allowing easier analysis and visualization of time domain data in MATLAB software. The addition of this functionality involves the extension of the existing OPC Toolbox functions getdata and opcread to support the creation of MATLAB time series objects. The new functions opcstruct2timeseries and opcqid have also been added to the toolbox to support this feature. More information is available on the reference pages for these functions.
