摘　　要：EPA是我国第一个拥有自主知识产权并被国际电工委员会(IEC)认可的工业自动化领域国际标准。本文在研究EPA协议一致性测试原理、静态测试与动态测试方法与实现技术的基础上,参照TTCN的结构框架对EPA抽象测试集进行形式化描述,提出了一种EPA协议一致性测试的方法,阐述了EPA协议实现一致性说明和协议实施附加信息的生成方法,并以变量写服务的测试为例,说明了EPA协议一致性测试流程。国家863/CIMS验收专家组委托的专家测试表明这种测试方法能够准确测试出被测协议实现与标准的一致程度。EPA is an international standard adopted by IEC. Meantime, it is the first Chinese national fieldbus standard with independent intellectual property rights. Based on researching the principle of EPA protocol conformance test and the method and implementation technologies of the static and dynamic tests, the EPA Abstract Test Suite is described according to Tree and Tabular Combined Notation （TYCN）. An EPA protocol conformance test method is put forward. The generating methods of Protocol Implementation Conformance Statement （PICS） and Protocol Implementation Extra Information are also discussed. The test process of the EPA protocol conformance test system is presented using the implementation of variable write service test as an example. The testing that was done by the expert group of the state 863/CIMS indicates that the proposed method can qualify the consistency of the IUT with standard accurately.
