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);
}

这个是windows版本的.就是用串口通讯线将两台机子用串口连起来进行通讯，最简单的。比如在a机上输入一个字符，在b机上能显示出来
-This is a windows version of the. Serial communication is to use two machines will be used for serial-link appear, the most simple. For example, in a plane into a character, b plane will display

Through the MP (on behalf of one of P I) of high 4 to control, AA `BB`
通过MP（代表其中一个P口）的高4位来控制，AA`BB`-4，5，6，7脚。12细分，没行数组里面分4对，每对数第一个加到P口控制电流方向，第二个数控制通电时间。正转AA`-BB`-A`A-B`B,数组由1到12行的读取，反转B`B-A`A-BB`-AA`,数组由12到1行的读取。参数POWER表示电机启动还是不启动，DIRECT参数表示方向，SPEED表示速度等级，每项通电时间用数组中的植/SPEED。本程序没考虑要走多少步的情况，调用一次就走一步。-Through the MP (on behalf of one of P I) of high 4 to control, AA `BB`-4,5,6,7 feet. 12 segments, no line inside the sub-array of four pairs, each of the P added to the number of the first current direction of population control, the second time the number of control power. Are transferred AA `-BB`-A `AB` B, the array from 1-12 line read, reverse B `BA` A-BB `-AA`, array 12-1 by the line read. POWER express motor parameters activated or not activated, DIRECT express direction parameter, SPEED express speed grades, each time power array sik/SPEED. This procedure did not consider how to go step-by-step situation, call a step away.
