SerialPortElf

C#写的控制串口继电器模块的代码，通过发送指令来控制多路串口继电器的开关。(Serial port control relay module C# to write the code, switch by sending commands to control multiple serial relay.)

这个程序是利用VC编写的一个从机串口响应modbus查询命令程序，实现RTU方式，3.5和1.5个字符时间检测，CRC和LRC校验。(This program is written using VC as a response from the machine serial modbus query command procedure, to achieve RTU mode, 3.5 and 1.5 characters time detection, CRC and LRC check.)

转载，自己需要一些串口程序与控件的应用知识，希望能够和大家共同学习，共同进步！(reproduce, they need some serial procedures and controls the application of knowledge, and we hope to be able to learn together. common progress!)

调试使用的串口助手，程序源码，功能齐全，可以调试程序(Serial Port Assistant for Debugging, Program Source Code, Full-featured, Debugging Program)

利用VB语言实现对串口进行操作，从而实现通过串口进行远程关机的操作，了解相关编程方法。(VB language serial port operation through the serial port for remote shutdown operation, understanding related programming methods.)

vb 串口上位机 很简单的一个版本，大家自己扩展功能吧 (com executed on pc,it s a simple version ,easy for expansion)

用VB编写的FX系列PLC通信动态链接库,用户只需调用API函数就可以简单的实现串口通讯(VB prepared by the FX series PLC communication dynamic link library, Users only need to call API functions can be achieved by a simple serial communications)

XWP仪表参数的读取，是帮1个朋友编写的(Instrument parameters XWP read, is to help a friend prepare the)

modbusRTU Communications with RS485

通过和OMron PLC通讯，实时监控自动化设备运行，并下发指令控制(Through the communication with OMron PLC, real-time monitoring of automatic device operation, and instruction control)
