Development of Network Control System of Tobacco Packing Machine

Abstract

A network control system used for tobacco packing machine is developed in this paper. The key technologies including software framework of monitoring program and network communication of S5-135 multi-processor PLC are researched in depth. Furthermore, the functions and characters of the network control system are analyzed. This control system realizes communications between monitoring station and S5-135 multi-processor PLC using PROFIBUS protocol, and the integration between PROFIBUS and enterprise information network MIS at the same time. This control system has already been implemented in one large-scale tobacco group successfully, and good economic benefits have been achieved
