背景
本人近十年的工作都与工业软件相关、其中工控系统开发过程中有一个必要环节就是跟各大厂商的PLC通信，对于从互联网行业进入工业互联网行业的员工来说，要实现各种型号PLC通信仍然需要一个过程，我在这里对主流型号PLC总结通信实现，供大家参考。
AB-CIP实现以太网通信
1、开发语言 开发语言为C# 2.包装通信库 包装所有通信的关键代码Wongoing.Plc.Communication.dll中 3.在项目中引用Wongoing.Plc.Communication.dll 4、实现PLC读写测试代码如下：
using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Linq; using System.Text; using System.Windows.Forms; using Wongoing.Plc.Communication; namespace WinTestApp {
public partial class Form1 : Form {
private Wongoing.Plc.Communication.Profinet.AllenBradley.AllenBradleyNet equip = new Wongoing.Plc.Communication.Profinet.AllenBradley.AllenBradleyNet("192.168.4.200"); public Form1() {
InitializeComponent(); } private void button1_Click(object sender, EventArgs e) {
OperateResult result = this.equip.ConnectServer();
if (result.IsSuccess)
{
Console.WriteLine("连接成功!");
}
else
{
Console.WriteLine("连接失败!");
Console.WriteLine(result.ToMessageShowString());
}
}
private void button2_Click(object sender, EventArgs e)
{
