Detection platform and method for Beckhoff PLC modules

Abstract

The invention discloses a detection platform and method for Beckhoff PLC modules. The detection platform for the Beckhoff PLC modules comprises a touch displayer, an industrial personal computer, a 1# master station, a 2# slave station, a 3# slave station and a power supply unit, wherein the 1# master station comprises a profibus master station module, a basic CPU module and a power module; the 2# slave station comprises a bus terminal controller, an I / O level module which comprises a digital quantity output module, and a terminal module; the 3# slave station comprises a bus terminal coupler, an I / O level module which comprises a digital quantity input module, a digital quantity output module, an analog quantity input module and an analog quantity output module, and a terminal module; the touch displayer is connected with the industrial personal computer, the basic CPU module is connected with the industrial personal computer, the profibus master station module is connected with the bus terminal controller and the bus terminal coupler, the bus terminal controller is connected with the industrial personal computer, and all the Beckhoff PLC modules or part of the Beckhoff PLC modules can serve as Beckhoff PLC modules to be detected. According to the detection platform and method for the Beckhoff PLC modules, due to the fact that a bus system is established, performance of the Beckhoff PLC modules can be detected, and the maintenance pass rate or the ex-factory pass rate is improved.

Description

technical field [0001] The invention relates to the field of PLC detection, in particular to a Beckhoff PLC module detection platform and detection method. Background technique [0002] With the progress of society and the process of industrial automation, PLC has been fully applied and developed with its advantages of high reliability, easy operation and flexibility. Among them, the automatic control system built with Beckhoff PLC modules has been applied in various industries due to its advantages of stability and quick response. The main control system of most wind turbine manufacturers is built by Beckhoff PLC module, which mainly realizes process control, safety protection, fault detection, parameter setting, data recording, human-machine interface of wind turbines, and is equipped with a variety of communication The interface can realize local communication and long-distance communication. However, because the wind turbines are located at the end of the entire power ...

AI Technical Summary

Problems solved by technology

However, because the wind turbines are located at the end of the entire power grid, and the quality of the power grid is poor, and the units are operated in high temperature and cold conditions, the number of Beckhoff PLC modules that have failed is large. In order to save costs, the Beckhoff PLC that will fail now Modules are used for maintenance and secondary utilization, improving the utilization rate of spare parts
