关于C#与三菱FX-3U通讯的问题_course

最近需要做一个三菱FX-3U监控程序,现在决定用mx component做串口通讯, 在PLC上装上了232-BD模块,用自带的axActFXCPU读写FX2n完全没问题,但是到了FX3U上就不行了.

哪位有C#与三菱PLC通讯的源码，最好有实例_course

最近小弟想用C#编写上位机与三菱PLC通讯，并对PLC内的软元件地址监控 不知哪位大侠，有这方面的实例，借小弟观摩下！

c#和三菱plc（Q系列）通过tcp通讯问题_course

各位大神， C#和三菱PLC直接通讯（不用Kepware）。 我看了网上介绍，比如调用MXComponent组件 还有内置以太网接口CPU和以太网通讯模块 内置以太网支持MC协议和套接字 。 想问下：

C#和三菱PLC socket网络通信_course

以下代码是用C++和PLC通信，但是我看不懂C++，能帮我把这段代码用C#的形式写出来吗？ 或者有能直接和PLC网络通信的C#源码，感谢各位高手，谢谢，非常感谢~~~ ------------------------------------------------------------------------ #include "stdafx.h" #include "SensorMounter.h" #include "SocketThread.h" IMPLEMENT_DYNCREATE(CSocketThread, CWinThread) CSocketThread::CSocketThread() : m_sIPAddress(_T("")) { m_nSocketPort = 0;

C#控制三菱PLC_course

在哪能买到C#控制三菱PLC的源码吗？ 要求：1、可以写入、读出寄存器的数值； 2、可以进行元件(Y、M、S、C、T)的置、复位操作； 3、可以读取元件(X、Y、M、S、C、T)的ON/OFF状态;
