Function generation method and device, equipment and medium

Abstract

The invention discloses a function generation method and device, equipment and a medium, and the method comprises that: a client side responds to a function node creation instruction, creates a function node in the client side, and transmits operation data during the creation of the function node to a server, so that the server can also create function nodes with the same parameters in an addressspace. And after the client acquires the function code edited by the user, a value is assigned to a function node in the client, and operation data during function assignment is sent to the server, sothat the server can assign the value to the function node in the address space to obtain an operable function with a logic function. According to the method provided by the embodiment of the invention, the function creation right can be given to the user, the flexible and changeable user requirements can be better met, and the user experience is improved. In addition, in the method, the functioncodes can be hosted through a function, namely a platform, so that a user can select a proper language to realize code logic, and language independence is achieved.

Description

technical field [0001] The present invention relates to the field of the Internet of Things, and in particular to a function generation method, device, equipment and medium. Background technique [0002] OPC UA is a very important C / S architecture industrial IoT communication protocol, which has the functions of communication and information modeling. Compared with the traditional OPC DA communication protocol, it has added many advantages, one of which is is the function. Functions are the only way to provide algorithmic services in the information model. Based on functions, OPC UA can improve the interoperability between clients and servers. [0003] However, the functions in the official protocol specification of OPC UA must be implemented in the server background, that is, the function code can only be solidified in the background when developing the OPC UA server, and it is completely oriented to server background developers, and users cannot implement function creatio...

Problems solved by technology

[0003] However, the functions in the official protocol specification of OPC UA must be implemented in the server background, that is, the function code can only be solidified in the background when developing the OPC UA server, and it is completely oriented to server background developers, and users cannot implement function creation on the client side according to actual needs. In the existing technology, the function modeling of OPC UA information modeling software can only create function signatures, and cannot edit function codes, which means that functions are just empty shells without real logical functions

Therefore, it cannot meet the flexible and changeable business requirements in the actual situation during use, resulting in poor user experience
