Embodiment Construction

[0013] The EPA Protocol Implementation Conformance Statement (PICS) is an easy-to-read description of the services and objects implemented by the tested EPA product, including the structure of the PICS file, parameter value symbol rules, supported application services, supported object types, and test databases . Any EPA device under test should configure the PICS file according to this prescribed procedure, and the test tool uses the PICS file to manage and explain the test results of the conformance test.

[0014] The invention adopts a kind of formal language to describe the abstract test set of EPA, thereby designing the test set in the graphic format suitable for human understanding. like figure 1 As shown, the tree-structure hierarchical model of the abstract test set (ATS), which uses a vertically layered and horizontally grouped tree-structured hierarchical model to describe the EPA abstract test set, is vertically divided into EPA abstract test sets, test groups, and...

Abstract

The method divides objects to be tested into test group, determines test objective of each group, picks-up abstract test cases, and defining test steps of test cases so as to form abstract test set ATS. Based on objects and services or functions supported by EPA protocol implementation consistency statement PICS and protocol implementation extraneous information text PIXIT of objects to be tested, relevant testing cases are selected from ATS so as to form executable tests set ETS needed for carrying out test for objects to be tested as well as form test dispatching table. According to sequence in test dispatching table, executing testing cases accomplishes consistency test for EPA products. The invention is in use for carrying out consistency test for products applied in industry control network in EPA protocol.

Description

technical field [0001] The invention relates to the field of automatic control, in particular to the communication protocol testing technology in the automatic control system. 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. The conformance test is the basis of other tests such as interoperability. Only when the entities passing the conformance test show that they comply with the standard protocol can it be meaningful to conduct other tests such as interoperability. However, there is no convenient and accurate metho...
