This article describes a technique for control/monitor of a distributed system from one point wherein all operations are centralized into two controllers. (Image Omitted) The automatic packaging and palletizing system (APPS) consists of a group of Personal Computers (PCs) communicating over a local area network (LAN), as illustrated in Fig. 1. Each computer is responsible for monitoring and controlling a section/zone of the manufacturing line, as shown in Fig. 2. Because of the fact that the zone controllers are spread throughout the area, it is difficult for one operator to manage the entire line. The technique described herein resolves this in that all the control/monitoring operations are centralized in two controllers. The two controllers involved are the APPS area controller and the APPS audit trail.
