OPC Toolbox

OPC Data Access Techniques

OPC Toolbox lets you discover, access, and read raw and processed data from any data historian compliant with the OPC Historical Data Access standard. You can also access live data from an OPC Data Access server in three ways:

• Execute all OPC Toolbox functions directly from the MATLAB command line or incorporate them into your own MATLAB applications
• Use the graphical user interface (GUI) to rapidly connect to OPC DA servers; to create and configure OPC Toolbox objects; and to read, write, and log data
• Use the Simulink blocks from OPC Toolbox to read and write data to and from an OPC DA server while simulating a system

Simulink model created using Simulink blocks from OPC Toolbox. These blocks let you communicate with OPC data directly to and from Simulink and your process system.
