Abstract
Exemplary methods and systems are directed to a process control system having a main control device for controlling a primary equipment of the primary system and a backup control device for controlling the primary equipment in case of a failure of the first control device. A command redirection device for the process control system, is adapted to receive a control command destined to the main control device, and to redirect, in the event of a failure of the main control device, said control command to the backup control device.
