摘要
在介绍EPA设备模型的基础上,重点分析了EPA功能块的结构模型,并以模拟输入功能块AI为例,探讨了EPA功能块的工作流程以及软件实现方法。开发的模拟输入功能块AI通过EPA互操作性测试软件测试,其测试结果表明此AI符合EPA功能块规范。
Based on the introduction to the EPA device model, EPA function block model and its structure are analyzed in detail. With the example of AI, the workflow of the EPA function block and its software implementation method are discussed. All EPA function blocks are tested by EPA interoperability test software developed by Shenyang Institute of Automation Chinese Academy of Sciences. The test result indicates that the AI function block conforms to the EPA function block criterion.
