| Abstract: | 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. |
