Embodiment Construction

[0059] This test method mainly includes the following aspects:

[0060] 1) Test content

[0061] a) Link layer test, which mainly examines the transmission mode, message frame format, address field, check code and link transmission status, to ensure that the device can give a correct response and be able to operate normally when the link layer is normal or abnormal. run;

[0062] b) Function code test, which mainly examines whether the format and transmission process of the function code meet the requirements of the standard, and, when the function code is abnormal, whether the device can respond abnormally;

[0063] c) Data field test, which mainly examines whether the format and data of the data field meet the requirements of the standard;

[0064] d) Application function test, on the basis of the realization of protocol consistency, check whether the application function of the device is correctly realized;

[0065] e) Data correctness test, on the basis of the realizati...

Abstract

The invention relates to an MODBUS-RTU protocol conformance test method which belongs to the field of information data transfer technologies of a power system. The method utilizes a protocol test toolfor inspecting whether the implementation of a protocol conforms to the standard or not, utilizes a test instrument for imposing an alternating current component and assists the completion of verification of application functions and data accuracy, and the test content comprises the protocol conformance test and the verification of the application functions and the data accuracy, wherein, the protocol conformance test comprises the normal test and the negative test of a link layer, functional codes and a data field. The test method gives out the systematic and the comprehensive test content and the test method of the MODBUS-RTU protocol, thereby having important significance for ensuring the conformance and the interoperability of the protocol.

Description

technical field [0001] The invention relates to a MODBUS-RTU protocol consistency testing method, which belongs to the technical field of power system information data transmission. Background technique [0002] With the rapid development of the power system and the continuous application of new technologies, higher requirements are placed on the sharing of information and data. How to better complete the sharing of information and data has always been a problem faced by the power system. The communication protocol is a description of the communication protocol part of the device under test, mainly including the address table, supported application functions and corresponding function codes, and special requirements for application functions. [0003] As a method to realize information data transmission, the communication protocol has been paid much attention to its realization. The Modbus-RTU protocol has been supported by everyone because of its simple and delicate struct...
