[0002] The PLC module is a commonly used control hardware device for industrial control. The stability and durability of the PLC module make it have a strong application range in industrial control. However, the creation of existing engineering control modules has a small selection range and is inconvenient to use. , each time a modification or new project is made, it needs to be redeveloped on the basis of the logic of the original PLC module, which increases the time required for the secondary development of the engineering control module and cannot guarantee the safety of the original logic of the project

Embodiment 1

[0015] Take AB module L73 loading automatic stacking program as an example. Firstly, the PLC to be loaded is operated by the automatic stacking program through the RSlogix5000 software of the AB system. When creating the automatic stacking program, open the RSlogix5000 software, edit the program through the editing module, create a new array edited by the remote MSG, and copy the source program The input and output arrays in are associated with it, establish the input and output associated arrays of the automatic stacking program, select the memory card, write the input and output associated arrays of the automatic stacking program into the CPU, and encrypt the automatic stacking program after the writing is completed Processing, each part of the logic is layered for encryption operations, and the encryption keys are generated and placed in different folders. The corresponding program personnel in the corresponding management department can view or modify the corresponding cont...

Embodiment 2

[0017] Take AB module L73 loading automatic reclaiming program as an example. Firstly, the PLC to be loaded is automatically operated by the RSlogix5000 software of the AB system. When creating the automatic material retrieval program, open the RSlogix5000 software, edit the program through the editing module, create a new array edited by the remote MSG, and copy the source program The input and output arrays in the program are associated with it, and the input and output associated arrays of the automatic retrieving program are established, and the memory card is selected, and the input and output associated arrays of the automatic retrieving program are written into the CPU. After the writing is completed, the automatic retrieving program is encrypted. Processing, each part of the logic is layered for encryption operations, and the encryption keys are generated and placed in different folders. The corresponding program personnel in the corresponding management department can ...

Abstract

The present invention relates to an AB system-based PLC plug and play module creation method. The creation method comprises the following steps of firstly operating a to-be-loaded PLC via an RSlogix5000 software; when the programs are created, editing the programs via an editing module; selecting a memory card, and writing the input output correlation arrays of the needed programs in a CPU; after writing, encrypting the programs; packaging the encrypted CPU, namely finishing the creation. According to the PLC module creation method of the present invention, a PLC module has the very strong stability, is diversified in types, has a large selectable interval and saves the cost; a user uses the module by editing an MSG, is convenient to use, the time needed by the secondary development of an engineering control module is reduced, and the original plant area control logic does not need to be displayed to the redevelopers, thereby guaranteeing the safety of an original file, and being able to furthest guarantee that the original PLC logic is not influenced by the redevelopers.

Description

technical field [0001] The invention relates to the technical field of programmable controllers, in particular to a method for creating a PLC plug-and-play module based on an AB system. Background technique [0002] The PLC module is a commonly used control hardware device for industrial control. The stability and durability of the PLC module make it have a strong application range in industrial control. However, the creation of existing engineering control modules has a small selection range and is inconvenient to use. , every time a modification is made or a new project is added, it needs to be redeveloped on the basis of the original PLC module logic, which increases the time required for the secondary development of the engineering control module and cannot guarantee the safety of the original logic of the project. Contents of the invention [0003] The invention aims to solve the deficiencies of the prior art, and provides a method for creating a PLC plug-and-play mod...
