Abstract

An operator station for a manufacturing process control system including a network of at least one dedicated process control computer for monitoring and controlling SECTIONS of the manufacturing process wherein each SECTION includes one or more SEQUENCES of the manufacturing process, the operator station includes a processor, a communication link to the process control communication system, a display including a SECTIONS window providing information relating to at least one of the SECTIONS monitored by the operating station and a SEQUENCE window providing information relating to one or more SEQUENCES monitored by the operator station, a data input device for selecting a SECTION from which information is to be displayed. The operator station may further include a flow sheet display window which includes a graphic depiction of a portion of the process, and a trend display window which includes current and historical information in graphic form for selected process control variables.
