基于现场总线的柔性制造系统信息实时控制

为实现对STAR-FMS柔性制造系统现场设备的实时控制,设计了基于PROFIBUS-DP的控制系统,解决了控制中心与现场设备的通信问题。阐述了系统构成、PROFIBUS-DP总线的控制方案、通信原理以及信息的实时控制。系统采用S7-300和WINCC作为主站,S7-200、ET200和变频器作为从站。以PROFIBUS-DP总线作为通信基础,既实现了对整个系统的集中控制,又能够分散控制各底层设备,同时使监控画面根据现场实际情况动态显示。应用结果表明,该控制系统设计可行,整个系统运行稳定、可靠,能够实现多级实时控制。

Real-time control for flexible manufacturing systems based on PROFIBUS-DP

To realize real-time control of field devices on flexible manufacturing system（FMS）,the control system based on PROFIBUS-DP was developed,and communication problems between control center and production site were solved.System configuration,the control scheme of PROFIBUS-DP,communication theory and information real-time control were focused on.S7-300 PLC and WINCC were used as the master stations.S7-200 PLC,ET200 and converter were adopted as the slave stations.The whole system as well as the field devices can be well controlled via PROFIUS-DPi,mplementing the centralized and distributed control,and at the same time the monitor screen dynamical-ly displays the actual situation.It is proved by the practical results that the design of control system is feasible,the entire system runs stably and reliably,and it realizes multi-level real-time control.
