A HART-enabled plug-in migration tool for Fisher Provox Series 20 distributed control systems (DCS) has been launched by Invensys Operations Management.
 Betty Naylor-McDevitt, director of control and safety solutions at Invensys, explains that Provox system users can now easily upgrade to the Foxboro I/A Series DCS.
They can then modernise plant control coverage with HART field communications and diagnostics, while also using Invensys' InFusion enterprise control system (ECS) technologies, without the massive cost of field rewiring.
Termination assemblies, system enclosures and power supplies all remain untouched, with the Invensys system merely replacing the Fisher I/O modules, designed to plug directly into the existing system nests.
These are based on Invensys' latest I/A Series 200 Series fieldbus module technology, providing HART capability for better device diagnostics and asset management.
"We make migrating from a legacy control system to a modern control system easy, low-risk and cost-effective," insists Naylor-McDevitt.
"The resulting new DCS provides the foundation and components for easily expanding into a powerful InFusion Enterprise Control System, with the ability to add additional hardware and software. This helps users leverage existing Invensys and third-party systems to achieve control and overall operational excellence," she adds.
