摘　　要：应用S7-216的自由通信接口技术实现焊条生产线的自动控制.采用简单的控制方法实现在严格意义下的多回路调节控制,避免了多回路调节控制增加系统的复杂性和硬件成本等问题.介绍S7-200系列自由通讯口的编程和实现PLC对多台变频器的控制方法,讨论系统的硬件结构并且给出了部分实现控制的应用程序.Based on the S7-216 free interface communication technology, the auto-control system of the welding-red production line was designed. In the control system, a simple control which substituted for the multiple-loop servomechanism was applied. The simple control decreased the complexity and the hardware cost of the control system. In the paper, the program of the free interface communication, the control of PLC for the inverter and the hardware structure as well as control program based on S7-200 series were also introduced.
