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]

JTAPI是由Sun公司提出的基于Java语言的应用程序接口。由于JTAPI是基于Java的应用接口，使得JTAPI的对象独立于操作系统和硬件平台，支持跨平台的应用。JTAPI定义了一套类库，包含电话功能和扩充功能。JTAPI结合了传统的电话服务和Web处理能力，具有较强的功能。但是，基于Java的特性，使得JTAPI在拥有强大功能的同时，也失去了普及和推广的基础。-JTAPI by Sun"s Java language on the application program interface. As JTAPI is a Java-based application interface, JTAPI makes the object independent of operating systems and hardware platforms to support cross-platform applications. JTAPI definition of a set of class libraries, including telephone functions and expansion capabilities. JTAPI combination of traditional telephone services and Web processing capability, and a strong function. However, based on Java, which makes JTAPI the powerful functions, lost popularize and promote the foundation.
