摘　　要：主要以EPA现场控制器的控制模块为研究对象,首先介绍基于EPA的功能块及其应用进程,接着阐述控制模块开发中的重点工作:管理功能块、技术块和控制运算模块的设计重点实现流程,并简要介绍了控制器的XML设备描述文件的开发。最后通过把控制器挂接在EPA实验网络上,对控制模块进行了分析,结果表明该控制模块能够有效完成控制功能。Taking the control module of EPA field controller as the main study object,the function block and its application process based on EPA were introduced. The design key and implementation flow of management function module, technique module and control computing module in developing control module were discussed. The development of XML device description document of controller was briefly introduced. Finally, the control module is analyzed by attaching the controller to EPA experimental network and the results show that the control module can implement control functions effectively.
