ABSTRACT
With the continuous development of science and technology on the
world today, the application of advanced techniques to impulse the
industrialization and modernization of our country is the most essential
thing to do. In this paper, we would like to introduce to readers an
application of communication network - Profibus to controlling a
flexible manufacturing system using PLC S7-300 (CPU 315-2DP) of
Siemens. This is a model of flexible manufacturing system working as a
chain of assembling and sorting products in diferrent colors to
appropriate storages from FESTO (Germany). The system consists of
five stations using PLC S7-300 and one station of Robot doing
assembly for completing product. All PLC stations are completely
controlled and supervised on computer with SCADA software
connecting to PLC master using MPI device; and using PROFIBUS
network in order to communicate with other PLCs.
