SOME SOFTWARE ELEMENTS OF THE MICROPROCESSOR MEASURING STATION
R Dragan · 2007
SUMMARY Last couple of years the Department of Industrial informatics has been developing industrial control systems. As a result, a distributed control system (DCS) has been developed. The practical applications of the system in industrial plants, especially in power consumption control and copper metallurgy production processes, confirms designed system performances in real environment. The kernel of control systems is the microprocessor measuring station - MMS. In hardware and software point of view MMS is a type of PLC (Programmable Logic Controller) with some of local and remote functional possibilities. The MMS hardware configuration is adapted for actual process control requirements with adequate number of input channels and adequate response time. It is mainly dedicated as an interactive node of industrial LAN. If it is necessary, MMS can operate autonomous, doing measuring and collecting the results, as a data logger. That is a MMU (Mobile Measuring Unit) version. The paper describes the software structure of the executive system and its main functions. The details of communications software and local operation control program are out of scope of this article.
