Control Report from Jim Montague: Lost in the sauce

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.

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.
