Abstract
Techniques for controlling the operation of a process plant or several process plants within a process control system using a centralized or distributed controller farm allow for increased flexibility in the process control system. Any of the controllers in the controller farm may be utilized to execute modules corresponding to any of the field devices in one or several process plants. Control modules or other operations may be allocated amongst the controllers distributing the load so that one controller is not performing several operations while others are inactive. Additionally, the controller farm may be located in a temperature controlled room or area in an offsite location from the process plants. In some scenarios, load balancing techniques are performed to distribute the load for the modules equally or at least similarly amongst the controllers.
