Abstract
The technology used in process automation is evolving towards distributed control systems, both as physical and functional characteristics and structures. In this paper, we present a prototype oriented to distributed process control with a set of special characteristics: low computational load, low requirements of bit rate, medium reliability and very low cost. A system based on general purpose microcontrollers can support the communications system and specific application load. In a larger volume of production of these systems, the software is the element that helps to reduce the cost of the system. This is the reason to design a distributed control system in which every possible function has been developed by software. Finally, an analysis has been done to evaluate the real limitations.
