Abstract: Aiming at the opening up problem in the field of industrial control, by analyzing the principles of conformance and interoperability test for field bus, this paper designs and implements an EPA conformance and interoperability test system, and expresses its design ideas in the function, procedures framework and test process. Input specification documents before test are designed. Consistency and interoperability test on the products based on EPA standard with the system verifies the feasibility of the design scheme.

Key words: EPA standard, conformance test, interoperability test

摘要： 针对工业控制领域的开放性问题，通过分析现场总线一致性与互操作性测试原理，设计和实现一个EPA一致性与互操作性测试系统，阐述该系统在功能、程序框架以及测试流程等方面的设计思想，针对测试前的输入文件进行规范设计。利用该系统对基于EPA标准的产品进行一致性与互操作性测试，实验结果验证了该设计方案的可行性。
