            //client.Write("Q1.3", true);
            //client.Write("V2205", (short)11);
            //client.Write("V2209", 33);

            //3、读操作
            var value1 = client.ReadBoolean("Q1.3").Value;

            var value3 = client.ReadInt32("V2209").Value;

            //4、如果没有主动Open，则会每次读写操作的时候自动打开自动和关闭连接，这样会使读写效率大大减低。所以建议手动Open和Close。

            var result = client.ReadInt16("V2205");
            //5.1 读取是否成功（true或false）
            var isSucceed = result.IsSucceed;
            //5.2 读取失败的异常信息
            var errMsg = result.Err;
            //5.3 读取操作实际发送的请求报文
            var requst = result.Requst;
            //5.4 读取操作服务端响应的报文
            var response = result.Response;
            //5.5 读取到的值
            var value = result.Value;
        }
