Diseño e implementación de un sistema de control distribuido (DCS) utilizando el sistema modular de comunicación (MPS), mediante el protocolo de comunicación Profibus

Abstract

Design and implementation of a Distributed Control System (DCS) using the modular production system (MPS) by the profibus communication protocol: laboratory automation UPS south campus. Noting the need to improve communication between existing modules in the laboratory automation, users being students themselves, and feeling problems, march began this project with the aim of improving practice for future students. The process will be monitored through a computer, which will be outside of the production area, and is provided using the ethernet protocol, using a data bus between the computer and the PLC station one or supply. The HMI screen, which is within the production area and will serve to put the operator in a state of “start" and "stop " production, in addition to showing what state are the most important variables of the process, communicate by the PLC profibus protocol of the first station . Only two of the four support PLC profibus PLC station and one or sourcing PLC station three or machining , so this protocol for communication between them will be used , communication with other PLC will be through MPI protocol .
