Abstract

A microcomputer ring in which each node collects data coming from its own cluster of measuring instruments has been implemented at the microcomputer laboratory of the Industrial Automation Department of the University of Brescia. The authors present the architecture of this ring, and discuss in detail both the structure of each node and the scheme of the diagnostic protocol, used to ensure identification of faulty nodes and reinsertion of repaired ones
