Abstract
The advent of digital technologies has brought a new dimension to process control. The rapid progress in computer and digital electronics go to replace the analog control with the digital control. This paper describes a way to control of the process with an IBM-PC compatible computer. After a brief description of the microcomputers the interface process is described. The schedule of the process interface and the theses performances are described. An example of implementation of the process control with the IBM-PC compatible computer are presented and the performances are discussed.
