Description: FreeMODBUS 是针对通用的Modbus协议栈在嵌入式系统中应用的一个实现。Modbus协议是一个在工业制造领域中得到广泛应用的一个网络协议。一个Modbus通信协议栈包括两层：定义了数据结构和功能Modbus应用协议和网络层。在FreeMODBUS的当前版本中，提供了Modbus Application Protocol v1.1a 的实现并且支持在Modbus over serial line specification 1.0中定义的RTU/ASCII传输模式。从0.7版本开始，FreeModbus也支持在TCP defined in Modbus Messaging on TCP/IP Implementation Guide v1.0a中定义的TCP传输。Freemodbus遵循BSD[1] ，这意味着本协议栈的实现代码可以应用于商业用途。-FreeMODBUS is common Modbus protocol stack for embedded systems applications in an implementation. Modbus protocol is an area in the industrial manufacturing of a widely used network protocol. A Modbus communication protocol stack including the two: the definition of a data structure and function of Modbus Application Protocol and network layer. In FreeMODBUS current version, provides a Modbus Application Protocol v1.1a implementation and support for Modbus over serial line specification 1.0 as defined in RTU/ASCII transfer mode. Starting from the 0.7 version, FreeModbus also supports TCP defined in Modbus Messaging on TCP/IP Implementation Guide v1.0a defined in the TCP transmission. Freemodbus follow the BSD [1], which means that the protocol stack implementation of the code can be used for commercial purposes.

Description: 为什么要移植Freemodbus，这个问题需要从两个方面来回答。第一，modbus是一个非常好的应用层协议，它很简洁也相对完善。对于还没有接触过modbus的朋友来说，我非常不建议直接移植freemodbus，应该耐心的从modbus文档入手，并充分把握身边的所有资源，例如PLC的中modbus部分。第二，其实嵌入式系统的通信协议可以自己制定，但是通过实践发现自己定制的协议漏洞百出，尤其是扩展极为困难。我始终认为借鉴他人的经验是很好的途径。借鉴他人成熟的代码，可以减少调试的时间，实现的功能也多了不少。
个人观点，仅供参考。
freemodbus小提示
freemodbus只能使用从机功能。freemodbus更适合嵌入式系统，虽然例子中也有WIN32的例子，如果想要做PC机程序并实现主机功能，推荐使用另一个modbus库——NMODBUS，使用C#开发。同样WINFORM也可以通过自己编写串口代码实现modbus功能，但是这会花费很长的时间，可能是一周也可能是一个月，如果使用现成的代码库，那么开发时间可能只有10分钟。-Why transplant Freemodbus, this issue needs to be answered in two ways . First , modbus is a very good application layer protocol , it is very simple and relatively perfect. For no contact with modbus friends, I do not recommend direct transplant freemodbus, the patient should start from modbus documents and take full advantage of all the resources around you , for example, part of the modbus PLC. Second, the fact communication protocol embedded systems can develop their own , but through practice found loopholes own custom protocols , especially the expansion is extremely difficult. I have always believed that draw on the experience of others is a good way . Learn from others mature code can reduce debugging time , functions are also a lot more .
Personal point of view , for reference only .
freemodbus Tips
freemodbus only from the machine function . freemodbus more suitable for embedded systems, although there are examples of WIN32 example , if you want

Description: FreeModbus是一款开源的Modbus协议栈，但是只有从机开源，主机源码是需要收费的。同时网上也没有发现比较好的开源的Modbus主机协议栈，所以才开发这款支持主机模式的FreeModbus协议栈。本版FreeModbus版本号更改为V1.6，特性如下：
新增加的主机源码与原有从机的风格及接口保持一致；
支持主机与从机在同一协议栈运行；
支持实时操作系统及裸机移植；
为应用提供多种请求模式，用户可以选择阻塞还是非阻塞模式，自定义超时时间等，方便应用层灵活调用；
支持所有常用的Modbus方法。(FreeModbus is an open source Modbus protocol stack, but only from the machine open source, the host source code is required to charge. At the same time the Internet did not find a better open source Modbus host protocol stack, so it developed this support host mode FreeModbus protocol stack. This version of FreeModbus version number changed to V1.6, features are as follows:
The new host source code and the original slave style and interface to keep in line;
Support the host and slave in the same protocol stack to run;
Support real-time operating system and bare metal transplant;
For the application to provide a variety of request mode, the user can choose to block or non-blocking mode, custom timeout, etc., to facilitate the application layer flexible call;
Supports all commonly used Modbus methods.)
