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. Platform: |

ModBus 网络是一个工业通信系统，由带智能终端的可编程序控制器和计算机通过公用线路或局部专
用线路连接而成。其系统结构既包括硬件、亦包括软件。它可应用于各种数据采集和过程监控。
为更好地普及和推动 Modbus 在基于以太网上的分布式应用，目前施耐德公司已将 Modbus 协议的

Be connected by line. Its system structure includes both hardware and software. It can be applied to various data acquisition and process monitoring.
In order to better popularize and promote Modbus's distributed applications based on Ethernet, Schneider Inc has already put Modbus protocol into practice
