摘要
针对现代烟厂要求控制系统能集中管理、分散控制生产线的要求,对烟厂梗丝线控制系统进行了改进。改进后的系统采用西门子S7通信协议,通过PROFIBUS-DP网络将所有生产环节的PLC连接到同一个控制系统中,形成了主主通信控制系统。操作员通过Win CC或任一主站(采用西门子S7-300/400系列PLC)即可查看整条梗丝线的生产情况。Win CC临界报警功能有利于操作人员提前做出规避操作。改进后的系统操作灵活,管理便捷,节约了人力资源。
Modem cigarette factory requires its control systems to be able to centralized management, decentralized control production lines. In response to this requirement, the control system of tobacco factory cut stem production line is updated. The improved system uses Siemens S7 communication protocol, PLC of all production processes were connected to the same control system via PROFIBUS- DP network, forming master-master communication control system. The operator can view the entire cut stem production through Win CC or any master （Siemens S7-300/400 series PLC）. Win CC Criti- cal alarm function can help the operator to make evasive action in advance. The improved system can be operated flexibly, managed easily, and it saves human resources.
