Problems solved by technology

[0005] When using the manual test method to test the PLC, the physical condition and professional quality of the testers are required to be high during the test. Misoperations caused by various external factors greatly interfere with the test, so the reliability of the test results It will also be greatly affected; at the same time, due to the need to manually complete each test step, the test efficiency is low, which affects the development progress of the PLC

Abstract

The invention provides an automatic test method used for a programmable controller and an automatic test device thereof. The test efficiency can be enhanced by batch automatic compiling, automatic performing, test result automatic display and storage and test report automatic generation of test cases, and misoperation caused by manual testing of test personnel can be avoided so that excessive dependence of the test process on the professional quality of the test personnel can be reduced and the test accuracy can be enhanced. Meanwhile, the test report includes the single step test result and the final test result of each test case so that the test personnel are enabled to judge the problematic test step of the test according to each corresponding singe step test result, the test personnel are enabled to locate the problem and feedback the problem to the development personnel for modification and thus the research and development progress of the product can be accelerated.

Description

technical field [0001] The invention relates to the technical field of automatic control, in particular to an automatic testing method and device for a programmable controller. Background technique [0002] Programmable control systems play an extremely important role in the field of industrial control automation technology, and are widely used in automation control systems in various industries such as petroleum, chemical industry, high-speed rail, and electric power. Programmable Logic Controller (PLC) is the core of the programmable control system. It is mainly used to run the control logic and perform on-site I / O variable refresh operations. Its operating status is directly related to the correctness of the operating results of the entire programmable control system. , it can be seen that the correctness and reliability of PLC operation are particularly critical to the safety of industrial control sites. [0003] In order to improve the accuracy and reliability of PLC o...
