台达变频器和PLC通讯功能的实现方法

The Communication Method Between Delta Inverter and PLC

本文讲述了ModBus通讯相关的一些知识,并以台达PLC和变频器为实例,给出了两种实现通讯的方法。旨在让大家学会利用通讯功能实现PLC对变频器的控制。

This paper discussed the knowledge of ModBus communication. And give two communicate ways Based on Delta, PLC and inverter. I hope form this, the others can learn the technique how to use PLC control the inverters from communication function.
