An identified state of the plant is signaled and the plant is monitored for normal execution of any transition, identifying a current task being performed in the process and sending a message to different sections of the plant. Results are displayed on a visual display device and can be sent to other plant computer programs for guidance during the transition. A permanent chronological record of the sequence of events—modes and transitions—of the plant and sections and subsections including the pertinent plant conditions and information is generated for subsequent review and analysis.Other References
