Get Started with OPC Toolbox

OPC Toolbox™ provides 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.

With OPC Toolbox you can work with data from live servers and data historians that conform to the OPC Data Access (DA) standard, the OPC Historical Data Access (HDA) standard, and the OPC Unified Architecture (UA) standard. The toolbox lets you securely connect to OPC UA servers using a variety of security modes, algorithms, and authentication methods.

The product includes Simulink blocks that let you model online supervisory control and perform hardware-in-the-loop controller testing.

About OPC Servers and Clients

• Overview of OPC, Servers, and the Toolbox
  

  Provides an overview of OPC principles and OPC Toolbox software.

• OPC Historical Data Access
  

  The OPC Historical Data Access (HDA) standard provides an interoperable platform to store and exchange historical process data.

• About OPC Unified Architecture
  

  The OPC Unified Architecture (OPC UA) standard combines all the capabilities of OPC Data Access and OPC Historical Data Access standards (together, referred to as "OPC Classic") and adds various additional capabilities into a single, extensible standard.
