Abstract: This paper presents the new design principles and implementation method of a generalprocess control package for a micro total distributed control system based on the MCS--51 single chipprocessor, with emphasis on hardware structure of the micro total distributed control system, automatic generation of general control software, implementation method and key technique of main data structureand program structure, etc.. This software package is programmed with TURBO C 2.0 version -andMCS-51 assembly language.
