With the rapid improvement of industrial automation, the wide application of computers in the industrial sector, people's requirements for industrial automation are increasingly high, and the variety of control equipment and process monitoring devices in industrial areas, making traditional industrial control software Unable to meet the various needs of users. When developing traditional industrial control software, once there is a change in industrial controlled objects, the source program of its control system must be modified, resulting in a long development cycle; the development and successful industrial control software has been made to each control project. Its repetition is very low, causing its price very expensive; when the source program of the industrial control software is modified, if the original programmer is left, the source program must be modified with other people or novices, so It is quite difficult. The emergence of universal industrial automation configuration software provides a new way to solve the above practical engineering issues, as it can solve all kinds of problems in traditional industrial control software, users can use their own control objects and control purposes. Arbitrary configuration, complete the final automation control engineering. Configuration is a modular arbitrary combination. General configuration software is mainly characterized by (1) continuity and expansibility. Applications developed with universal configuration software, when the site (including hardware devices or system structures) or user requirements change, there is no need to make updates and upgrades for software; (2) Packaging (easy to learn Use), the functions that the general configuration software can complete with a method for easy users to use, for users, do not need to master too many programming language technologies (even without programming technology), they can be completed well. All functions required by complex projects; (3) versatility, each user uses the underlying device (PLC, smart instrument, smart module, board, frequency converter, etc.) of general configuration software according to the actual situation of the project / O Driver, open database and picture production tools can complete an animation effect, real-time data processing, historical data, and curves coexisting, multimedia functionality and network function, are not subject to industry restrictions. The earliest development of common configuration software is the configuration software in the DOS environment, which is characterized by the basic features of a simple man-machine interface (MMI), a gallery, and drawing toolbox. With the widespread application of Windows, configuration software in the Windows environment has become mainstream. The configuration software in the DOS environment becomes mainstream. Compared with the configuration software in the DOS environment, its most prominent feature is that graphics functions have great enhancements. Many foreign excellent general configuration software is developed in English, it has long application time, user interface is not ideal, does not support or free support for domestic universally used hardware equipment, configuration software itself and configuration software training fees High factors, these are the reasons why domestic general configuration software cannot be widely used in China. With the continuous improvement of domestic computer level and industrial automation, the market demand for general configuration software is increasing. In recent years, some technical strength has been developing universal configuration software for domestic use.
