Graceful Reincarnation of Legacy Industrial Control Systems

Challenge of graceful migration through upgrades and updates is a daunting task for process control systems. Issues confronted include aging hardware and software, as well as shortage of process experts with knowledge of vintage control systems. We offer techniques and solutions for graceful evolution to current generation control system. Our approach covers entire system including HMI, Controller, I/O and Field Interface Layers. We showcase stepwise implementation approach while addressing the concerns. We also provide cost-benefit analysis and pre-requisites for choosing specific evolution path.
