Abstract

The purpose of this thesis is to present an approach to remote monitoring and operation of distributed real time process control systems. Conventional monitoring of process control systems currently requires a great deal of close supervision from trained personnel located on-site. In many cases, researchers, developers or maintenance personnel cannot be at every location where such a system is installed. Currently, a standardized architecture for remote access to such systems is not available. In addition, most of these systems are very expensive and under-utilized. Researchers would benefit by having access to different parts of a system concurrently The benefits of a layered architecture for remote process monitoring and control will be analyzed through the use of a demonstration system that was realized to examine the real time performance of the interconnection mechanisms between the process controller(s) and the system monitoring interfaces. Low level, real-time process control is achieved by using specialized networking schemes called fieldbusses to interconnect all control devices. In this system, fieldbus controllers will also assume the role of servers connected to the Internet, in order to make device information available to any local or remote clients. In the proposed architecture, remote clients are user interfaces, implemented as JAVA applets, which can be accessed with a web browser. The proposed system architecture allows for client interfaces to gain remote access to various types of fieldbusses transparently.
