摘　　要：提出了以太网工厂自动化协议一致性测试的原理和方法,介绍了该协议一致性测试系统的体系结构。根据该协议中的应用层服务的定义及协议的要求,研究了该协议中的服务测试的原理及测试方法,并以域上载服务的测试为例,展示了以太网工厂自动化服务测试的测试过程。通过以太网工厂自动化一致性测试系统的实际应用,证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。According to the characteristics and requirements of Ethernet for Plant Automation （EPA） protocol, the principle and method for conformance test of this protocol were presented. Then, the architecture of the EPA conformance test system was depicted. Based on the definition of application layer service and requests of EPA, principle and test method of services in this protocol were also analyzed, and the test process was brought forth by an example of domain uploading service test. Finally, application of EPA conformance test system verified the effectiveness of this method.
