OPC Toolbox
Read and write data from OPC servers and data historians
OPC Toolbox™ provides a connection to OPC DA and OPC HDA servers, giving you access to live and
historical OPC data directly from MATLAB® and Simulink®. You can read, write, and log OPC data from
devices, such as distributed control systems, supervisory control and data acquisition systems, and programmable
logic controllers, that conform to the OPC Foundation Data Access (DA) standard. You can read and analyze data
from any data historian that conforms to the OPC Foundation Historical Data Access (HDA) standard.
The product includes Simulink blocks that let you model online supervisory control and perform
hardware-in-the-loop controller testing.
Key Features
▪ OPC Foundation Data Access standard v2.05a support
▪ OPC Foundation Historical Data Access standard v1.20 support
▪ Simultaneous data logging and numerical processing
▪ Simultaneous connections to multiple OPC servers
▪ Access to historical data for analysis and statistical processing
▪ Communication with OPC servers using synchronous or asynchronous operations
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.
