Abstract

Computer graphics is being used more and more to provide operator windows to an industrial process, but the development and interfacing are difficult and tedious. As more dedicated microcomputer based control systems are being used in industry, there is more need for computer process display systems that are in the same cost category as control systems. Presently, there is no microprocessor based system that permits plant personnel to develop and interface a process display graph in a simple parameterized way, without the need of a computer systems specialist. This thesis presents a parameterized graphic development and interface software package (IGDISP) developed in Fortran 77 on a PDP 11/44 driving a RAMTEK 9351 raster graphic terminal. IGDISP allows the plant process engineer to develop his own process graph without having to write any software.

As part of the design of IGDISP, a human factors study of man to computer graphics display was conducted, with special emphasis being given to those features involved with industrial graphics systems. Different graphical methods used to best illustrate an industrial process are reviewed. The aim of the human factors study is to assist the IGDISP and other industrial computer graphics user to develop the best process window to his process.
