Field Level Communications Corner – December 20222

    New UAFX specifications have passed in-depth OPCF member reviews and extensive prototyping to ensure their implementations maintain cross-vendor interoperability. As such, automation vendors can now start adopting UAFX functionality in their offerings, and end-users can look forward to the advantages that UAFX-based field communications offer.

    Compliance Corner – December 2022

      The Compliance Working Group has been busy this year, focusing on improving test cases in three main areas: Companion Specifications, OPC UA Field EXchange (UAFX), and Ethernet-APL. More devices than planned were tested in 2022, and demand is already strong for 2023.

      Energy Efficiency – Building a Unified Model with OPC UA

        Dr. Karl-Heinz Niemann of the University of Applied Sciences and Arts in Hannover, Germany, is running a project called, “Development of energy management interfaces for IoT technologies” (IoT_EnRG). The project recognized, very early on, that OPC UA was critical to harmonize and model energy consumption data.

        Enabling OPC UA and TSN for Field Devices

          Analog Devices, Arm, Amazon Web Services (AWS), B&R Industrial Automation, Lattice Semiconductor, Schneider Electric and Texas Instruments, entered a collaboration to create a permissive, open source OPC UA over TSN (Time Sensitive Networking) stack on FreeRTOS.

          Use-Cases for OPC UA Methods, Pub/Sub, & Companion Specs

            By now, we expect that most readers have probably used or explored using the OPC UA standards. What you may not realize is the power available to you in other parts of the OPC UA standard. In this article we will cover the 3 functionalities we are seeing most often: Methods, Pub/Sub, and Companion Specifications.

            OPC UA for Adaptive Production Lines and Diversified Products

              The world is changing rapidly, and automakers are required to balance quality with product diversification. In response, manufacturing sites need to deploy production lines more frequently and earlier with quality traceability whilst maintaining conventional productivity. Via OPC UA, Omron is helping them to natively integrate with IT systems.

              Empower End-Users with OPC UA Data Modeling

                If data connectivity to individual 3rd party OT applications and components is the foundation, then organizing that OT data into meaningful contexts is the cornerstone. As such, Matrikon Data Broker (MDB) data technology (DT) is both the foundation and the cornerstone.
