Some may question why a programming language is industrial software.

1715-OF8I As everyone knows, the programming language used in the field of industrial control, especially the graphical programming language, is very different from the programming language in the field of IT. The programming languages used in industrial control are used to express and realize the functions that must be completed by the control system, and these functions are formulated in strict accordance with the process requirements and processing sequence. The industrial production process is ever-changing, and after continuous abstraction and refining, it is basically a continuous process for process industry, logical control for discrete manufacturing, sequence control and motion control (or a collection of these three controls), and a batch batch process that has both discrete and continuous.

Function block diagram can perfectly express various requirements of continuous process control, ladder diagram and sequence function diagram can perfectly express various requirements of discrete process control. The software that integrates these graphical programming 1715-OF8I languages to realize programming is compiled by using some relevant mathematical methods (such as graph theory, logic algebra, etc.) in the programming language of IT field.

It can be inferred that the programming language used in the field of industrial control not only belongs to the basic software used in the control category of industrial software, but also the most widely used class of industrial software. What’s more, the development of more than 20 years has formed a comprehensive unified engineering platform software suite including outline design, detailed design, programming, debugging, operation and maintenance, engineering project management, etc., which has been the standard configuration and system basis for companies that can stand on their own in the field of automation.

A mature control system application software needs to go through the process of 1715-OF8I design, verification and testing, according to the V&V mode after the outline design of the system, it will be divided into modules for detailed design, and then start to write code. Then it is necessary to integrate all the modules to form a system application, and pass the hardware-in-the-loop simulation test and inspection. These processes, although rigorous, greatly limit the progress and efficiency of the work. The IEC 61131 standard defines several control languages, but relies on a model of a single controller rather than a distributed system. The main improvement of the IEC 61499 standard is that it allows the integration of control system modeling and development into a single system, but a distributed system at deployment time. This creates a prerequisite for the future development of simulation without hardware in the loop.

peroration

The future unified engineering platform will certainly greatly improve the design of engineering 1715-OF8I projects, and even the efficiency and quality of on-site commissioning, operation and maintenance. The rapid development of the controller, its linkage with the control class industrial software, will make the automation rise to a new realm.
