    The architecture makes economic sense, but changes will make it better

    Figure 1: From a real estate standpoint, developing something so it is “backwards compatible” has the potential to make the DCN a reality
    Often overlooked, I/O Systems remain critical to any control loop
    This simplified Open Process Automation (OPA) reference architecture shows what types of devices ExxonMobil and its OPA Testbed Lab are evaluating for conformance with O-PAS, V2.1 and whether they can meet ExxonMobil’s requirements for field use. Components tested include: 1) industrial PC (IPC)-based distributed control node (DCN) computing without local I/O, 2) network-connected remote I/O, 3) advanced computing platform hosting virtual DCNs, and 4) DCNs with local I/O. They’ll likely be deployed in ExxonMobil’s OPA field trial that’s expected to start operating later this year in a manufacturing automation system at an ExxonMobil facility in Baton Rouge, LA.

    A pioneering open process automation (OPA) testbed by ExxonMobil serves as a model for other and is culminating in a operational field trial this year
    These profiles for “distributed control node (DCN)—I/O” and “DCN—compute” are two of the five developed by OPAF to clarify the roles and requirements that suppliers need to meet to produce products that comply with the Open Process Automation Standard (O-PAS), Version 2.1, that was finalized in the first week of February. This “Rosetta stone” for the physical platform defines locations in the O-PAS reference architecture where DCNs are deployed, and the conformance requirement profiles for each configuration, such as system management, OPC UA networking, security and others.

    O-PAS sets the pace: in this second of a three-part series, members of the Open Process Automation Forum presented their progress report at the ARC Industry Forum in Orlando
