Mx Component软元件的读取

最近做项目需要用MX读取三菱PLC，网上找了份编程文档，写了一个读取的工具类，批量和单独读取。

注意，MX读取PLC只能编译成32位的。贴一下自己写的简单工具类，记录一下。

导入的包：

写的代码:

using ActUtlTypeLib;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace XXXX.Util
{
    class MxCommuniUtil
    {
        private ActUtlType actUtlType = null;
        /// 

        /// 是否打开连接
        /// 
        private bool _isOpen = false;
        private int stationNumber = 0;  //我的连接默认0
        public string message = null;
        private static MxCommuniUtil mxUtil;
        private MxCommuniUtil() { }

        public static MxCommuniUtil Instance()
        {
            if (mxUtil == null)
            {
                return new MxCommuniUtil();
            }
            return mxUtil;
        }
