For forty years, process plants have run on control systems defined by a single vendor's platform. That architecture delivered reliability — and quietly imposed a ceiling on how fast a plant can change. Open Process Automation removes that ceiling.

This is a practical guide to the architectural shift behind O-PAS™, the open, vendor-neutral standard from the Open Process Automation Forum. It moves past principles to structure: how distributed control nodes, a shared connectivity framework, and a common information model let an operator compose a control system from conformant components rather than buy it whole.

Inside, you'll find a clear treatment of the O-PAS architecture and execution model, the "late binding" that compresses project timelines, migration through coexistence, procurement by interface, lifecycle economics, governance, failure modes, and the full business case for architectural control — plus a case study of the ExxonMobil-led OPAF program.

Written for engineers, system integrators, and the operations leaders deciding what comes after the DCS.

Store Description

We first started out as ?The Paperback Exchange,? a chain of physical bookstores where we would part exchange your beloved books for new stories to transport you to faraway places. However, as shopping started to evolve to online shops and marketplaces, we bid our stores goodbye to become ?PBShop.? This transition has only allowed us to blossom as we now ship thousands of titles to book lovers across the globe. We pride ourselves in being a community of local book lovers which allows our passion and devotion to shine in everything we do. In 2020 we not only celebrated our 20th birthday but our 1st birthday as being completely employee owned after becoming an E.O.T in September 2019. We are proud to be different and embrace standing apart on a book mountain by working from a virtual inventory which allows us to provide thousands of books that may be difficult to get for your bookshelf or your studies. Working with a number of different suppliers allows us to explore other avenues such as puzzles, sheet music and even stationery so we really do have something for everyone. Life is about being versatile in all realms of existence. If this is your first visit or you are a returning customer, we would like to welcome you to the PBShop family, for there is no friend as loyal as a book. We are a company who put our customers at the centre of everything we do as we understand the importance of reading because once you learn to read, you will forever be free. There are a whole lot of things in this world of ours that we are yet to explore, which is why we will forever inspire curious minds.
