Reading, Writing, and Logging OPC Data
The core of any OPC Toolbox software application is the
exchange of data between the MATLAB workspace and one or more
OPC servers. You create and configure toolbox objects to support the
reading, writing, and data logging functions that you require for
your application.
Using OPC Toolbox software you can exchange data with an
OPC server in a number of ways. You can read and write data from the MATLAB command
line or other MATLAB functions. You can configure toolbox objects
to automatically run MATLAB code when the server notifies the
objects that data has changed on the server. You can also log changes
in OPC server data to a disk file or to memory, for further analysis.
This chapter provides information on how to exchange data with
an OPC server.
