The Best of OPC UA Knowledge – Assembled for You

 You may know that Emerson PLC/PAC control systems are comprised of applications distributed on different hardware platforms and unified with a common information backbone – the OPC Unified Architecture (UA) framework. OPC UA is a secure, platform-independent, scalable, and object-oriented architecture for representing and communicating information. OPC UA provides a mechanism to protect the confidentiality and integrity of information and to determine whether applications are trustworthy – a fundamental need of the industrial internet.

Over the last year, we’ve posted a number of interesting blogs by Vibhoosh Gupta on OPC UA and why it matters to you. Since they’re all now available, we thought we’d remind you of these blogs and their content.

  1. OPC UA – The Client/Server Structure
    The benefit of OPC UA is platform independence, meaning the client can run seamlessly on Windows PCs or Linux PCs. Similarly, the servers can run on PCs (Windows/Linux) as well as on the real-time embedded PACs/PLCs over real-time OS such as QNX/vXWorks. This makes information ubiquitous.
  2. OPC UA – Objects, Nodes and Information Models
    OPC UA provides a whole extensible infrastructure for information modeling. Leveraging this infrastructure to its fullest has the potential to transform industrial automation by providing semantic interoperability from the device to the cloud.
  3. OPC UA – Aggregation Server
    The aggregation server allows the OPC UA backbone to scale at the enterprise level.
  4. OPC UA – Edge Computing and Inner/Outer Loop Control
    Edge control systems provide an intelligent and secure infrastructure for customers to create their control applications. These qualities in part are achieved with OPC UA.

The blogs can be read in order or pick one that interests you, and then let us know if you have any questions.

Are you using OPC UA at the edge?
