Embodiment Construction

[0016] The following are specific examples of the present invention, further describing the technical solutions of the present invention, but the protection scope of the present invention is not limited to these examples. All changes or equivalent substitutions that do not depart from the concept of the present invention are included in the protection scope of the present invention.

[0017] like figure 1 , 2 Shown, a kind of data reading method based on EGD mode, comprises the following steps:

[0018] 1) Configure the EGD program environment in the local computer, install the EGD universal connection program, connect to the remote EGD network, and establish access to the remote EGD data server;

[0019] 2) Connect to the EGD data server, install the programming software in the local computer, and call the EGD general program interface API, which will access the installed EGD general connection program;

[0020] 3) In the local development environment, access all variables...

Abstract

The invention relates to a data reading method based on an EGD mode. The method comprises the following steps that for reading data of Ethernet Global Data (EGD) of the EGD, configuration developmentis carried out on reading of EGD data, and unified configuration reading of data in an EGD mode is realized; meanwhile, when the read data is stored in the corresponding database, configuration is also carried out, the maintainability and stability of the system are greatly improved, and the workload of developers is greatly reduced; due to the fact that configuration management is achieved, whendata in a new EGD mode need to be read, secondary development is not needed, only the corresponding data ID needs to be found in the EGD manually, and configuration is conducted according to the information of the ID.

Description

technical field [0001] The invention belongs to the technical field of data reading, and in particular relates to an EGD-based data reading method. Background technique [0002] At present, for the data of the EGD method, it is generally necessary to encode the data according to which data is read. Whenever new EGD data is generated, it is necessary to rewrite the code and generate a new application program, which is time-consuming. And unstable. In order to solve the above-mentioned problems, this method adopts the method of configuring and reading EGD data, and configures the data in the EGD mode through the data ID (the unique sign of the data variable) and the length of each variable in the data ID. After the configuration is completed, the system will automatically read the EGD data according to the new configuration. At the same time, the read EGD data is also saved in the specified database in a configuration method, which not only ensures stability, but also improv...
