C#实现三菱FX5U PLC通信（基于MX Component库，支持GX Simulator3)

在上一个文章中我们讲过 三菱FX5U PLC支持多种通信协议，根据项目需求可选择不同的通讯方式，以下是几种主流通讯方式对比。

这段时间在网上搜了大量的C#连接FX5U的资源，大多都是积分下载图片，图片扫码收费。那在这里就给大家提供一个我用AI写的一个winform程序案例，通过MX Component库，实现C#与FX5U之间的通讯。

C#实现三菱FX5U PLC通信（基于MC协议 (SLMP/3E帧) - 原生TCP/IP）

上篇文章已经给大家提供了通过MC协议即原生TCP/IP与FX5U进行通讯。MC协议虽然支持多地址的批量读写，但是MC协议无法完成与GX WORK3自带的 GX Simulator3实现通讯，只能与实体PLC完成通讯。

那么通过三菱官方支持的MX Component库可以很好的解决这个问题，GX Simulator3 模拟 PLC 的“身体和大脑”（执行程序逻辑），而 MX Component 则模拟连接这个“虚拟PLC”的“通信电缆和协议”。 这样，就可以在没有任何实体PLC硬件的情况下，完整地测试上位机软件。

如上图所示，这是程序的使用页面，里面包含了单点操作、批量读取、批量写入、多地址读取，唯一不好的地方是X、Y、M不支持批量写入，MXComponent似乎只支持字的批量写入，而不支持位的批量写入。

在使用本程序之前请先安装MX Component，三菱官网下载即可，安装教程可以自行网上搜索，其中也包含通用的序列号。

安装完成后，打开Communication Settings Utility，点击Wizard...

输入你的逻辑站号Logical station number，设置1，因为在winform程序代码中我设置的为1.

如果你需要设置为其他的站号，请同步修改C#代码中的内容。

private void btnConnect_Click(object sender, EventArgs e) { //请同步修改LogicalStationNumber，保持与MX Component一致 plc.ActLogicalStationNumber = 1; int r = plc.Open(); if (r == 0) { connected = true; MessageBox.Show("PLC 连接成功"); UpdateConnectionStatus(true); } else { MessageBox.Show("连接失败：" + r); UpdateConnectionStatus(false); } }

设置完成后点击Next，如果已经设置过，则会弹出窗口选择，选择是即可。

在页面中，设置通讯，如果需要连接GX Simulator3，则在PC side I/F选择GX Simulator3。

在如果需要通过以太网连接FX5U则在PC side I/F选择Ethernet board，Connect module选择CPU module（FX5）。

点击next，在下一个页面中设置你的连接方式，交换机或网络直连。我测试时使用的网线直连（但也都插在交换机上），勾选Ethernet port direct connection，在下面的Select PC side adapter中选择你的网卡，选完你可以看到你的本机ip，确保与你的实体PLC能ping通即可。

设置完实体PLC或GX Simulator3后，点击next，为你的方案设置一个名称，随意设置即可。

设置完成点击Finish，点击Communication test，进入页面后，点击test，测试与实体PLC或GX Simulator3的通讯。如果连接成功会弹出下列窗口，点击确定后，将Communication Settings Utility缩小，请勿关闭。

打开winform程序，点击连接PLC，根据需求进行读取写入使用。
