基于USS协议的平面工作台变频调速系统的设计

The design of the frequency conversion speed regulation system based on USS protocol

通过对电机的远程速度控制,从而达到平面工作台远程速度控制的目的,设计系统利用USS协议来对S7-200PLC的自由口进行编程,通过PLC与变频器MM440的RS485通讯方式实现对电机的工作电流、运转速度以及变频器故障报警信息的远程监控,最终实现了平面工作台的变频调速。

By remote control motor speed, so as to achieve the purpose of the plane table remote speed control, design system used USS protocol to S7-200 PLC Freeport program, through PLC and inverter MM440's RS485 communication realized the motor work current,operating speed and RMON of the inverter fault alarm information, and ultimately the plane table frequency control.
