ABSTRACT:
A method includes obtaining current structural information describing a current structure of a process control system and retrieving from a checkpoint file stored structural information describing a previous structure of the process control system. If the current structural information matches the stored structural information, current configuration and operational information of a controller in the process control system is conformed to previous configuration and operational information stored in the checkpoint file.
