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); } 通过MODBUS TCP读写PLC源码 功能模块一：读写PLC主模块 using System; using System.Net; using System.Net.Sockets; public static void WriteWord(int mwAddress,int mwValue) {写字到以太网 if (init_plc() == 0) { try { hi = mwAddress / 256; low = mwAddress - hi * 256; hi1 = mwValue / 256; ///////////16bit low1 = mwValue - hi * 256; sendBuf[7] = 6; sendBuf[8] = (byte)hi; sendBuf[9] = (byte)low; sendBuf[10]
