Instrumentation zero basic system configuration, essential knowledge!

In the configuration software, a target application created by the configuration occupies a unique physical space (logical space) in the computer hard disk, which can be identified by a unique name, which is called an application. Multiple applications can be stored in the same computer. The configuration software accesses its configuration content by the name of the application, opens its configuration content for modification or loads its application into the computer memory for real-time operation.

There are many standards for the structure division of the configuration software. Here, the architecture is discussed by using the working phase of the software and the members of the software system to form two standards.

In terms of the working phase of the software, it can be said that it is divided according to the system environment. In general, the configuration software is composed of two parts:

The system development environment is the working environment that the automation engineering design engineer must rely on to implement its control scheme and perform the system generation of the application under the support of the configuration software. By creating a series of user data files, the final graphical target application system is generated for use by the system runtime environment. The system development environment consists of several configuration programs, such as a graphical interface configuration program, a real-time database configuration program, and so on.

System operating environment In the system running environment, the target application is loaded into the computer memory and put into real-time operation. The system running environment consists of several running programs, such as graphical interface running programs, real-time database running programs, and so on. The configuration software supports online configuration technology, that is, you can directly enter the configuration environment and modify the configuration without exiting the system operating environment, so that the modified configuration takes effect directly.

The first contact with the automation engineering design engineer is the system development environment. After a certain amount of system configuration and debugging, the target application is finally put into real-time operation in the system operation environment to complete an engineering project.

According to the membership structure, the configuration software has a certain degree of independence because of its powerful function, so its composition is an integrated software platform, which is composed of several program components.

Among them, the application manager is a dedicated management tool that provides functions such as searching, backing up, decompressing, and creating new applications. When an automation engineering design engineer applies configuration software for engineering design, he often encounters the following troubles: often need to back up the configuration data; often need to quote some of the configuration results (such as pictures) in the successful application projects; often You need to quickly understand which applications are saved on your computer. Although these requirements can be implemented manually, they are inefficient and error-prone. With the support of the application manager, these operations will be very simple.

The graphical interface development program is the development environment that the automation engineering design engineer relies on to implement the control scheme and perform the graphics system generation work supported by the graphics editing tool. The final graphical target application system is generated by creating a series of user data files for use by the graphical runtime environment.

Graphic interface running program In the system running environment, the graphic target application system is loaded into the computer memory by the graphical interface running program and put into real-time operation.

Real-time database system configuration program Some configuration software only adds simple data management functions in the graphical development environment, so it does not have a complete real-time database system. At present, more advanced configuration software (such as Force Control®) has independent real-time database components to improve the real-time performance of the system and enhance the processing capability. The real-time database system configuration program is a configuration tool for establishing a real-time database, which can define the structure, data source, data connection, data type and related parameters of the real-time database.

Real-time database system running program In the system running environment, the target real-time database and its application system are loaded into the computer memory by the real-time database system running program and perform various predetermined data calculation and data processing tasks. The query, retrieval and alarm management of historical data are all done in the real-time database system running program.
