Implementation of a PC-based operator interface for a paper machine drive

Abstract

Personal computers (PCs) are increasingly being used in industrial applications. Graphical user interface (GUI) software and Windows-based operating systems are proving to be cost-effective, rugged and reliable. These advances have allowed over the the successful installation of several human-machine interface (HMI) systems for paper machine winders. The HMI monitors the operation of a winder and provides complete machine control. An operator interface was developed to both monitor and control a multi-section paper machine drive. The application described highlights the use of a redundant multi-computer network to replace existing benchboard controls. New monitoring and control features and a unique reel roll-density-control scheme were included. The goals achieved were increased paper production and improved control of reel building.
