Seamlessly Upgrade Siemens Systems to DeltaV

Emerson’s engineering approach is different because it uses automated tools and libraries to migrate existing logic, apply proven templates, and standardize designs, which reduces manual effort, shortens project timelines, and minimizes errors compared to more manual, piecemeal methods. In addition, Emerson's experienced project execution teams follow structured project procedures—such as staged cutovers, factory-tested configurations, and repeatable workflows—that further reduce risk, improve schedule certainty, and ensure consistency across projects.

Yes—Emerson has completed nearly 8,000 successful migrations, including over 800 from Siemens systems. Customers have seen measurable benefits like increased production, reduced complexity, and on-time delivery. Case studies highlight real-world success, including a 20% production boost for a European chemical company during a complex batch migration.

Emerson reduces risk during transition by tailoring the migration approach to each customer’s needs using a wide suite of modernization technologies. With Console.Connect, Siemens and DeltaV systems can run in parallel from a single DeltaV console, allowing phased migration with no downtime. Flex.Connect and IO.Connect lower shutdown risk by reusing existing wiring and directly interfacing with Siemens I/O. Revamp automates code conversion and creates a digital workflow, removing manual touch points. Combined with engineering tools and Emerson’s proven processes, this approach minimizes disruption while preserving valuable control logic and ensuring a smooth, reliable cutover.

Emerson’s approach maximizes capital efficiency by leveraging existing assets, minimizing engineering work, and reducing installation time. Technologies like Flex.Connect and Electronic Marshalling reduce labor and material costs, while DeltaV’s flexibility supports brownfield upgrades without extensive redesign.

Although highly dependent on size and complexity, most migration projects can be completed within a few months of project kickoff, with plant downtime for a full rip-and-replace typically limited to 1-2 weeks. When downtime is the critical factor in project planning, our modernization solutions can take that down to days or even hours. Emerson has also executed several complex hot cutovers, removing downtime altogether.

Post-transition, Emerson provides 24/7 global support through Guardian, which delivers proactive updates, security patches, and lifecycle insights. Local service teams supplement this with onsite expertise, training, and ongoing assistance to ensure the system continues to run reliably and efficiently.

DeltaV supports compliance with standards like IEC 61511 and GAMP 5 through built-in audit trails, version control, and protected templates. Emerson’s tools help manage change control and validation, ensuring regulatory requirements are met during and after migration.

DeltaV migration solutions support the transition of Siemens control platforms while helping facilities modernize control hardware, operator interfaces, and automation infrastructure. This approach allows organizations to move to the DeltaV platform while reducing migration complexity and operational risk.

Many Siemens migration projects focus on preserving existing field infrastructure where practical while modernizing the control system layer. This can help reduce installation effort, shorten project schedules, and minimize disruption during migration activities.

DeltaV modernization tools and migration services help analyze existing Siemens applications and streamline the conversion process. This can reduce manual engineering effort while helping teams transition control strategies and operator environments more efficiently.

Common challenges include control logic conversion, operator interface migration, I/O integration, and project execution during limited shutdown windows. DeltaV migration solutions are designed to simplify these activities and support a more structured modernization approach.

Organizations often pursue Siemens-to-DeltaV migrations to address system obsolescence, simplify lifecycle support, improve operational flexibility, and gain access to modern automation capabilities. DeltaV provides a scalable platform that supports future expansion and digital transformation initiatives.
