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. T   -                -300 (CPU 315-  -      1 GII THIU    vit tt ca Process n mng c n l       n c    chun quc t 00.
