用VS2010编写的串口调试助手，很有用(Written with VS2010 serial debugging assistant, very useful)

说明：  Testing PC to DVP PLC connection

C#写的串口通信的,具体的大家看名字应该知道了(C# to write serial communications, specific names should we do know)

一款基于QT的串口助手源码,其中详细注释了串口的各种参数载入方法，实用有效(A string based on Qt serial helper source code, in which detailed comments on the serial port parameters of the various loading methods, practical and effective)

为了实现对船舶电站的实 时监控，对PLC编写程序，并在LabVIEW作为监控界面的情况，PLC与工控 机之间采用OPC技术实现通讯，GPC与工控机之间采用Modbus串口协议实现 通讯。最后在实现通讯的的基础上，对本系统进行了试验调试，并开发监控界 面。(In order to achieve real-time monitoring of ship power plant, the PLC programming and control interface as in the case of LabVIEW, PLC and IPC communication between the use of OPC technology, GPC and IPC used between the Modbus serial protocol communication. Finally, to achieve communication based on a test of the system to debug, and develop monitoring interface.)

介绍了一种点位运动控制器的设计，该控制器可以控制步进和伺服电机。该运动控制器以 STM32F103 为主控微处理器，实现了电机起停的加减速控制，扩展了 RS485 串行通信接口，设计了限位保护电 路，移植了嵌入式实时操作系统μC /OS-Ⅱ，通过μC /OS-Ⅱ来调度运动控制器的多个任务，设计了串口通信协议， 可以方便组成多轴控制系统.(Describes the design of a point of the motion controller, the controller can control a stepper and servo motors. The motion controller controlling microprocessor STM32F103, acceleration and deceleration control the motor starts and stops, extended RS485 serial communication interface, designed to limit protection circuits, transplantation of embedded real-time operating system μC/OS-Ⅱ μC/OS-Ⅱ scheduling multiple tasks of the motion controller, designed a serial communication protocol, can easily form a multi-axis control system.)

用于在线仪表的 modbus,仅供参考，(online instrument for modbus connection, for information purposes only, thank you)

arcsight logger api

通过读取PLC的opcserver中的数据并将数据上传至服务器，通过串口发给GPRS模块(By reading the PLC opcserver data and upload the data to the server, through the serial port to the GPRS module)

简洁的VB串口调试程序。适合初学者学习和参考(Simple VB serial debugger. Learning and reference for beginners)
