c# plc modibus 通信
c# 串口 以太网通信 modibus 连接 plc
从文本框输入负数 -2 补码=反+1=进位+原数
Vb 清除输入缓冲区 输出缓冲区 c#用不用清除？？哪个函数？？
//發送二進制數據 ？？？？？？？？？？？？？？
private void SendBytesData(SerialPort serialPort)
{ ////从 文本框取得数据 如果负数 -2 怎么办？？？？
byte[] bytesSend = Encoding.Default.GetBytes(txtSend.Text);
spcom.Write(bytesSend, 0, bytesSend.Length);

在局域网和广域网传输DNP V3.00。
Transporting DNP V3.00 over Local and Wide Area Network.
1 Overview
1.1 Purpose
DNP V3.00 (hereafter referred to simply as DNP) was designed for serial point-to-point communication (e.g. RS-232) with limited support for half duplex serial networks (e.g. RS-485). In order for devices to exchange DNP messages in a local (LAN) and/or wide area network (WAN), one must either augment the protocol to support a network environment or use an existing network transport mechanism. This document takes the latter approach specifically, to define how to transport DNP traffic on the internet protocol suite.
