Replace Aging DCS Systems

    Feb. 14, 2007
    A three-step migration program is designed to help manufacturers cost efficiently replace aging DCS systems with the vendor’s Logix Control Platform for improved productivity, lower costs and easier access to parts and service. Implementing a single control platform across all plant-floor applications provides manufacturers with advantages including reduced spare parts requirements, more synchronized processes and lower maintenance and training costs, says the vendor.
    It also improves plant-wide integration by enabling the seamless transfer of real-time data from disparate control systems for improved decision making and increased manufacturing flexibility. Phase one of the migration plan involves replacing legacy human-machine interface (HMI) consoles with the vendor’s FactoryTalk View Site HMI infrastructure. In phase two, the legacy process controllers are replaced with Logix controllers, while allowing customers to reuse existing I/O modules to maximize the return on their existing investment. Phase three involves removing the legacy I/O infrastructure and replacing it with the Logix 1756-based I/O platform. Custom field termination unit cables from the vendor allow the removal of legacy I/O without the need to remove field wires, reducing installation costs and risks associated with I/O replacement. The three-phase program is available today for conversion from Honeywell, ABB and Fisher Provox DCS platforms; upcoming solutions will accommodate Westinghouse, Moore and Yokogawa, among others, says the vendor.Rockwell Automation Inc.
