Field Level Communications Corner – Sept 2023

    New UAFX specifications have been released, along with revisions to existing editions. The latest release of the Conformance Test Tool (CTT) now also supports initial testing of the UAFX information model. Plus, find us at many upcoming events, particularly in Asia.

    OPC UA “REST” Subgroup Launched

      The REST group, as a sub-group of the OPC Foundation UA Working Group, will discuss use-cases for the integration of OPC UA via REST and propose potential extensions for the OPC UA specification. It is a special-purpose sub-group meant for IT (especially REST) experts and participants who work in Edge and Cloud computing.

      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.

        FLC / FX Corner – September 2022

          The Field Level Communications (FLC) Initiative has been busy: collaboration with FieldComm Group for instrumentation devices; archived webinars available to watch; controller-to-device (C2D) kickoff; OPC UA Safety technical paper published, and more.

          Achieving Interoperability for Process Automation Systems

            What is the Open Process Automation Standard (O-PAS) and why is it a future requirement for industries? What role does OPC UA play in the O-PAS Connectivity Framework? Learn more and get all of your burning questions answered.

            Field Level Communications (FLC) Corner – March 2022

              Three years after its launch, the OPC Foundation’s Field Level Communications (FLC) Initiative is preparing for the transition from the first UAFX specification version with the focus on Controller-to-Controller (C2C) to the second UAFX specification version which is extending the UAFX concepts to also cover the use-cases Controller-to-Devices (C2D) and Device-to-Device (D2D).

              OPC UA, MQTT, and Information Interoperability

                In earlier times, OPC learned a hard lesson that tying a spec to a particular wire protocol leads to obsolescence as technologies evolve. This is why OPC UA has a layered architecture, which makes it possible to create mappings for any number of transports like JSON HTTP or UA TCP for Client/Server models and MQTT or UA UDP for Pub/Sub models.

                OPC UA Field Level Communications (FLC) News

                  Three years after its launch, the OPC Foundation’s Field Level Communications (FLC) initiative has completed the OPC UA FX (Field eXchange) specifications. In addition, a multi-vendor demo with controllers and network infrastructure components from 20 companies has been realized.
