In recent years, the domestic PLC technology progress and market development prospects


At present, in terms of PLC basic programming software, what is presented in front of us can be summarized into 4 types:

1. From the self-developed PLC kernel based on international standards to a comprehensive integrated development environment IDE, but not the commercialization as the goal, only for their own control system service, or customized control system service. A typical example of this form is the CAS S system of the Yan Yi team of the School of Computer Science and Technology of Hangzhou Dianzi University, as well as Hollysys, China Control, Hangzhou Youwen, etc., to serve their own DCS products.

2. It is also developed from a self-developed PLC kernel based on international standards to a comprehensive integrated development environment IDE, the main feature is that it has been productized, and can provide commercial software packages for any unit in demand in society. Based on a team with 15 years of IEC 61131-3 programmable system research and development experience, Beijing Otus Technology is the most representative company of this kind of commercial platform in China.

3. Cooperate with foreign companies to develop a comprehensive development environment suitable for the needs of the domestic industrial control market based on their PLC cores, including providing a complete software environment and development path for localized embedded chips. The classic example is Shanghai Yicong Technology.

4. Fully based on its own development and use of the latest technology in the IT industry formed software platform. Its characteristics are that it can meet the various requirements of traditional PLC programming, but also adapt to the requirements of modern PLC used in the industrial Internet environment, and easily introduce artificial intelligence. Zhejiang Qingjie Intelligent Technology is doing pioneering work in this direction, and it has achieved good results.

If we evaluate the development status of a science and technology institution from the perspective of foresight and execution, these four models can be said to have their own focus, showing the differentiation of service objects and the differentiation of technical characteristics. It can basically meet the different needs of the current domestic PLC market for software development platforms, and has different development prospects and directions in the era of digital transformation. There are appropriate solutions and implementation solutions for the data governance necessary for the future PLC system to use AI services, and how to facilitate the use of open source AI basic algorithm library.
