Block Library Overview

Industrial Communication Toolbox™ software includes a Simulink® interface called the OPC block library. This library is a tool for sending data from your Simulink model to an OPC server, or querying an OPC server to receive live data into your model. You use blocks from the OPC block library with blocks from other Simulink libraries to create models capable of sophisticated OPC server communications.

The OPC block library requires Simulink, a tool for simulating dynamic systems. Simulink is a model definition environment. Use Simulink blocks to create a block diagram that represents the computations of your system or application. Simulink is also a model simulation environment in which you can see how your system behaves.

The best way to learn about the OPC block library is to observe an example, such as Read and Write Data from a Model.
