President’s Welcome – June 2021


    Please remember my previous Welcome article announcing a series of OPC UA for IT/Cloud activities including:

    • The “UA for Cloud Library” joint working group (JWG) together with CESMII for data models stored in the cloud
    • Cloud confederation for cross-platform data exchange – this initiative has started and completed a first specification under DIN 92222. It has been a pleasure for the OPC Foundation to cooperate with DIN to continue and extend this important work.
    • Definition of method calls, and single data reads/writes via MQTT in the works
    • The OPC Foundation’s “IIoT Starter Kit” as an important piece to show how easy it is to use OPC UA via MQTT to publish or subscribe data – but make use of standardized data and all other additional OPC UA services which are missing in MQTT only

    I am very proud of the teams that worked hard to be able to deliver all the related content at the upcoming OPC Day International in multiple sessions – we have an exciting agenda.

    Introducing OPC UAcademic Program

    The OPC Foundation has a long-standing tradition of working closely with academic institutions from around the world. As such, we are excited to launch the OPC UAcademic program as a logical next-step in that relationship to address a common market need.

    Regional Corner: Asean/Singapore

    In March 2021 we initiated the new “Reginal Corner” to report about OPC Foundation around the world. Starting with China here and Japan here in the previous newsletter, it’s a pleasure to highlight the OPC Hub ASEAN/Singapore here this time.

    Congratulations to Ethernet-APL Project!

    We are a very prominent main sponsor at Achema Pulse 2021 on June 15/16, 2021 to showcase OPC UA offerings for the process automation industry. In total the OPC Foundation will run 10 presentations, two live panel discussions with interesting topics on field and IT integration, and three workshops dedicated to “OPC UA in the Process Industry”. Just last year we joined the Ethernet-APL initiative; their excellent work over the years now results in the announcement of: “Ethernet-APL specifications are done and products are entering the market”.

    In our view, users will benefit from these four important building blocks:

    • The world’s largest ecosystem for secured industrial interoperability
    • OPC UA as the framework for secure information exchange
    • Standardized information models and semantics – such as the UA-based DEXPI, MDIS, PA-DIM, ProdML, WITSML, VDMA Weighing / Pumps / Mining / OPC UA for Machinery, and more
    • Ethernet APL connectivity from the edge to field devices
