FX3U-ENET-L 上位機(jī) TCP MC 協(xié)議報(bào)錯(cuò)  
手冊(cè)上的例子
           TcpClient tc = new TcpClient();
            tc.Connect("172.16.3.113", 9999);
            String TxCommand = "01ff000a4420000000000500";
            byte[] buf = System.Text.Encoding.Default.GetBytes(TxCommand);
            tc.GetStream().Write(buf, 0, buf.Length);
            byte[] InBuff = new byte[1024];
            while (tc.GetStream().DataAvailable)
            {
                tc.GetStream().Read(InBuff, 0, InBuff.Length);
                String RxResponse = System.Text.Encoding.Default.GetString(InBuff);
            }
            tc.Close();
寫入就ERR  LED 紅色
ERR end code 0050 sub Header 0030

問題找到謝謝各位，用ascii碼模式就行了
