PLC firmware system, interface packaging method and device, storage medium and electronic equipment

Abstract

The embodiment of the invention provides a PLC firmware system, an interface packaging method, a storage medium and electronic equipment. The PLC firmware system comprises an application software layer, an intermediate layer, an operating system layer, a board support package layer and a PLC hardware layer, wherein the intermediate layer is arranged between the application software layer and the operating system layer, and between the application software layer and the board support package layer, and is used for converting interfaces provided for the application software layer by different operating systems into standardized operating system adaptive interfaces and converting interfaces provided for the application software layer by the board support package layer into standardized boardsupport package adaptive interfaces. Due to the fact that the interfaces of the intermediate layer are standardized, compared with an application layer, the system only needs to realize one code module for the same service, and different code modules do not need to be provided for PLC products of different architectures, and therefore, the scheme can shield differences between all operation systems and hardware platforms, and an effective packaging layer is simplified.

Description

technical field [0001] The invention relates to the technical field of PLC software development framework, in particular to a PLC firmware system, a package interface method, a storage medium and electronic equipment. Background technique [0002] Programmable Logic Controller (PLC), because of its simple structure, easy control, and cheap price, is widely used in the industrial field. With the diversity of products, industrial production control is becoming more and more complex. As the brain of industrial control, PLC has to complete more and more work. [0003] The inventor found that the firmware developed by PLC products often needs to be modified related to the platform before it can be successfully transplanted to other platforms. With the increasing complexity of system functions and the differences of various operating platforms, this modification is very difficult. Increase. It not only requires software engineers to have a comprehensive understanding of the syst...

[0003] The inventor found that the firmware developed by PLC products often needs to be modified related to the platform before it can be successfully transplanted to other platforms. With the increasing complexity of system functions and the differences of various operating platforms, this modification is very difficult. Increase

It not only requires software engineers to have a comprehensive understanding of the system platform, but also has a good grasp of the software structure, and this process often takes a lot of time and effort, and the engineering cost is very high
