有做過上位機(jī)的朋友嗎，請教SQL批量獲取M0 256點(diǎn)  D0 256點(diǎn)，該如何做，關(guān)鍵是刷新時(shí)間問題
下面我是剛寫的思路往各位大神指正：

    /// <summary>
        /// Act控件初始化
       /// </summary>
        public Form1()
        {
            InitializeComponent();
            axActUtlType1.ActLogicalStationNumber = 10;
            axActUtlType1.ActPassword = "";
        }

// 按鈕獲取值
    private void button1_Click(object sender, EventArgs e)
        {
            textBox1.Clear();
            short[] M_Memory = new short[16];
            axActUtlType1.Open();
            axActUtlType1.ReadDeviceBlock2("m0", 256, out M_Memory[0]);
            for (int i = 0; i < 256; i++)
            {

                if (Mitsubishi.Mitsubishi_M_Memory(M_Memory) == true)
                {
                    textBox1.AppendText("M" + i + "= 1  ");
                }
                else
                {
                    textBox1.AppendText("M" + i + "= 0  ");
                }
            }
        }



        /// <summary>
        /// mx compoment讀取的值轉(zhuǎn)換成
        /// </summary>
        /// <param name="M_Ararry">要轉(zhuǎn)換的byte數(shù)組</param>
        /// <returns>B00L數(shù)組</returns>
        public static bool[] Mitsubishi_M_Memory(short[] M_Memory)
        {          
            int a = 0;
            bool[] b = new bool[256];
            for (int j = 0; j < M_Memory.Length; j++)
            {
                for (int i = 0; i < 16; i++)
                {
                    if ((0x01 & M_Memory[j] >> i) == 1)
                    {
                        b[a] = true;
                        a++;
                    }
                    else
                    {
                        b[a] = false;
                        a++;
                    }
                }
            }
            return b;
        }
