推荐答案

从三菱主页下载MX组件。



包含COM .dll以通过COM / USB / EtherNet连接到PLC



它们使用起来非常稳定且更容易写作自己沟通的东西。 （完成）



非常基本的例子：

Download MX Component from the Mitsubishi Homepage.

there are COM .dlls included to connect via COM/USB/EtherNet to the PLC

they are very stable to use and much easier as writing that communicating stuff on your own. (done that)

very basic example:

Dim _FX_COM As New ACTPCCOMLib.ActFXCPU
_FX_COM.ActBaudRate = 115200
_FX_COM.ActControl = 7
_FX_COM.ActCpuType = 520 'FX3U
_FX_COM.ActTimeOut = 100
_FX_COM.open

Dim value as short = 123

_FX_COM.w_write("D100", value)
