System and Method for Fault-tolerant Process Module Control Based on Seamless Control

摘要

The present invention relates to a process module control system and method for performing seamless control, wherein the process module control system of the present invention includes a master controller that controls a process module performing a process of a facility and the master controller when the master controller fails. one or more slave controllers for performing seamless control on the process module, wherein the master controller and one or more slave controllers from the process module during the process of the equipment transmit process module data for the process of the equipment one or more times In the event of a failure of the master controller, when a plurality of slave controllers are connected to the process module, any one of the plurality of slave controllers having the largest data size of the most recent data. The controller acts as the updated master controller, and the rest acts as the updated slave controller,
