利用S7-226实现变频器远程网络控制

A Realization of Telenet Control for MicroMaster Vector Based on S7-226 PLC

讨论了利用 SIEMENS S7- 2 2 6对多台变频器进行远程网络控制的方法。介绍了 S7- 2 2 6的通信协议 ,列举了 SIEMENSMMV系列变频器的参数设置 ,提出了实现方案 ,并给出了通讯程序。利用该方法 ,可以方便对各变频器的运行参数进行在线监测 。

This paper proposes the realization of the telenet control for many MicroMaster Vectors based on S7 226 PLC.The communication protocol of S7 226 PLC and the setting of MicroMaster Vector's communication parameter are detailed introduced.In addition,the realization scheme and the communication program are presented too.The presented system is very convenient to monitor the parameters of every MicroMaster Vector on line and realize the telenet control.
