A single Allen Bradley ControlLogix (or CompactLogix) PLC and PanelView Plus HMI control the Ingenious integrated packer that previously had individual HMIs for four packers (weight controllers), ultrasonic sealer controls, automatic bag applicator controls, conveyor controls, printer controls, checkweigher controls, and miscellaneous integration signals. To make a full changeover, an operator had to adjust settings in as many as 10 different controllers. This job is now done with one menu selection button; the information is communicated via Ethernet to all integrated components. Previous manual adjustments of equipment, such as moving the bag chair (saddle) to accommodate a longer or shorter bag, have been automated. There is no need for an operator to enter the equipment cell to make a change-over.
