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);
}
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]
