modbus serial communication

Serial Communication in Windows Unlike the serial communication programs in DOS, Windows does not recommend that applications directly control the hardware, but transmits data through the device driver provided by the Windows operating system. The serial port is processed as

-1- VC ++Application Design for Serial Communication Abstract: This article introduces a Serial Communication Class Integrated with Win32 API functions and the basic idea of C ++ class. Cserialport class. The following describes how to implement serial

In industrial control, Industrial Computer (generally based on Windows) often needs to communicate with smart meters through serial ports. Serial Communication is convenient and widely used.Generally, the Industrial Computer communicates with each smart meter through RS485 bus. The RS485 communication mode is half-dupl

The basic way of data communication can be divided into two kinds of parallel communication and serial communication:Parallel communication: Refers to the use of multiple data transmission lines to send a data to each of you simultaneously. It is characterized by fast transmission speed, suitable for short-distance

Java Serial communication detailed (GO)Author: denimcc Date: 2007-05-11 PrefaceWhen it comes to open source, I'm afraid few people don't pick Osashi praise. The students learned the knowledge through open source code, the programmer gained the successful experience of others through the open source Library and the ability to finish the project at hand on time, and the merchant made the money through open so

With the wide application of multi-microcomputer systems and the popularization of computer network technology, computer communication functions become more and more important.Computer communication refers to information exchange between a computer and an external device or between a computer and a computer.CommunicationParallel Communication and

Two independent asynchronous serial I/O ports are provided for the UART unit of the high-efficiency FIFO serial port based on the implementation of b0x (clock frequency: 60 MHz) on the ARM7, each communication port can work in the interrupt or DMA mode. That is, UART can generate an internal interrupt request or DMA request to transmit data between the CPU and th

Using Java to implement serial communication (under Windows System), we need to use the port package Javacomm20-win32.zip provided by Sun. There are three files to use, such as the following configuration:1.comm.jar placed to Java_home/jre/lib/ext;2.win32com.dll placed to Java_home/bin;3.javax.comm.properties two places to put them.Jre/lib (that is, the JRE in the Java directory)Java_home/jre/libTell me abo
