一. SOEM库简介
SOEM（Scalable Open EtherCAT Master 或 Simple Open EtherCAT Master）是一个开源的、用于EtherCAT通信协议的软件库。EtherCAT（Ethernet for Control Automation Technology）是一种实时以太网通信协议，广泛应用于自动化和机器人技术中，以其高速和低延迟特性而受到青睐。SOEM库允许开发者在他们的应用程序中实现EtherCAT主站功能，从而控制和驱动EtherCAT从站设备。
以下是SOEM库的一些关键特点和优势：
- 开源和免费：SOEM是开源的，使用LGPLv2.1授权，可以自由使用、修改和分发。
- 跨平台支持：SOEM支持多种操作系统，包括Linux、FreeRTOS、VxWorks、QNX等，提供跨平台的灵活性。
- 实时性能：SOEM直接与硬件交互，确保了低延迟和高数据吞吐量，满足实时性要求。
- 易于集成：SOEM使用标准的设备驱动模型，简化了在现有系统中添加EtherCAT功能的过程。
- 文档完善：提供详细的API文档和示例代码，帮助开发者快速上手。
- 社区支持：作为一个开源项目，SOEM拥有活跃的社区支持，不断有更新和问题解决方案。
SOEM库适用于工业自动化、实验室研究、开源硬件项目和教育用途等多种场景。它为用户应用程序提供了发送和接收EtherCAT帧的方法，支持读写过程数据、保持本地IO数据与全局IO映射同步、检测和管理系统错误等功能。
开发者可以通过研究SOEM的源码来深入理解EtherCAT主站与从站之间的交互方式，这不仅有助于学习EtherCAT协议，还能在此基础上进行定制和优化，以满足特定的应用需求。SOEM项目在GitHub上维护，提供了完整的示例应用和配置文件，方便开发者获取和使用。

通过-map指令，可以查看从站的I/O配置
slaveinfo \Device\NPF_{A837AD34-3738-42FF-8E0B-F5B0BE69ABD6} -map
五. WIN10下利用QT构建SOEM开发环境
-
在QT中创建一个新c++项目，CMakeList.txt文件如下
cmake_minimum_required(VERSION 3.5) project(SOEMTest LANGUAGES CXX) set(CMAKE_CXX_STANDARD 17) set(CMAKE_CXX_STANDARD_REQUIRED ON) set(SOEM_DIR "C:\\Users\\10001540\\Downloads\\SOEM-master") include_directories(${SOEM_DIR}\\install\\include\\soem\\ ${SOEM_DIR}\\oshw\\win32\\wpcap\\Include\\) link_directories(C:\\Users\\10001540\\Downloads\\SOEM-master\\build\\Debug\\ ${SOEM_DIR}\\oshw\\win32\\wpcap\\Lib\\x64\\) add_executable(SOEMTest main.cpp) target_link_libraries(SOEMTest PUBLIC soem.lib Packet.lib wpcap.lib Ws2_32.lib Winmm.lib) install(TARGETS SOEMTest LIBRARY DESTINATION ${CMAKE_INSTALL_LIBDIR}) message(STATUS "The system is: ${CMAKE_SYSTEM_NAME}") -
main函数中，代码如下：
