Abstract

This invention relates to EPA protocol conformance testing system and method, which contains EPA tester, network monitor equipment, time synchronous server, standard EPA equipment 1, standard EPA equipment 2, upper tester proxy, tester, tested EPA equipment, wherein the upper tester proxy embedded in tested EPA equipment protocol for receiving control message from tester and sending the received service and response to tester, the tester generating executable test group, executing test process according to test scheduler list determined according to executable test group, analyzing test result and producing test report.

Description

technical field [0001] The invention relates to the field of industrial control, in particular to a technology for performing EPA protocol consistency testing on EPA products. Background technique [0002] Given that Ethernet has the advantages of good openness, wide application, low price, high communication rate, rich software and hardware resources, global technical support, and strong sustainable development capabilities, products with EPA standards will have a large number of engineering applications, and a large number of projects The prerequisite for the application is that a large number of products must pass tests and certifications such as conformance and interoperability. Conformance testing is the basis for other testing such as interoperability. Only the entity that passes the conformance test shows that it conforms to the standard protocol, it is meaningful to conduct other tests such as interoperability. However, there is currently no method for performing E...
