Our Fortune 100 client needed to migrate their existing DCS-controlled chemical processes to the Emerson DeltaV DCS system, allowing them to achieve standardization and upgrade from older platforms that were no longer being supported by the manufacturer.


We helped our client develop a five-year master plan for the migration of processes located in several plants, executed as a series of focused projects that were managed by one or two controllers. Foth provided engineering support for this system migration, as well as development of the system configuration, the design and development of new control system drawings and panels, the preparation of electrical construction drawings and documents, checkout and startup commissioning, and operator training. We reused or replaced the client’s existing I/O, replaced workstations, revised networks and replaced Intrinsically Safe barriers.  To configure the new DeltaV control system, our team was responsible for reviewing the code of the existing control system and developing new functional specifications to drive the creation of new graphics, interlocks and alarms. In all, Foth migrated process control from Fisher-Provox, Moore APAC and Siemens S7/PCS7 systems to DeltaV.


The new DeltaV control system is current, scalable and fully supported by the manufacturer. It provides standardization, simplified maintenance and is the control system most preferred by our client’s plant operators.
