Industrial Automatic Control Systems and Controllers Annotation << Back Aspects of the Control Methodology of the Automated Document Exchange System Sobol V.M. The article discusses the issues of organizing an audit of a specialized automated system of document exchange. The possibilities of using a hardware and software simulator that interprets the regulations of the subscriber protocol, which is the basis of the family of telecommunication complexes, are described. The sequence of technological operations for sending and receiving a message is illustrated. The results of model experiments are presented. It is planned to specify a scenario of automated checks in a fi xed form of reproduction of message traffi c.
