Matrix Logic based on IEC61131-3 standard is the programming and comprehensive development platform of MatriBOX series edge intelligent controllers. Supports five programming languages (instruction table, function block diagram, ladder diagram, structured text, sequential function diagram), as well as C/C++ high-level language programming. Advanced structure, easy to master. It is equipped with rich function library files for direct programming calls. Integrated with the human-machine interface, the user can realize the upper monitoring program, alarm processing program, software oscilloscope and so on. Support distance maintenance and access, abnormal alarm real-time display, remote view of equipment logs, can configure SMS, email functions. Support OPC UA communication and MQTT, Sparkplug, RESTful and other protocols. Multiple encryption function, effectively protect the user’s intellectual property rights. In addition, it also has certain motion control functions, point control, encoder feedback, JOG\ electronic gear, electronic CAM and so on.

In addition, like the focus on PLC development and industrialization of Blue Pufeng Technology Co., LTD., has now become a series to provide large, medium and small PLC. Its large PLC RPC3000 has multiple redundancy functions such as CPU redundancy, power redundancy, communication redundancy, and I/O capacity can be expanded from thousands of points to 40,000 points.

Develop the domestic PLC market ecology a little superficial opinion

Although the domestic PLC development technology and application technology have made great progress in these years, the quality control of the manufacturing process, especially the quality control of mass production, still needs to be improved. PLC market in the 1980s and 1990s emerged in the rapid promotion and growth, fight products, fight quality, fight marketing scale of the way has changed, Siemens, Rockwell Automation and Mitsubishi Electric three dominant market for decades unchanged situation in a short time is difficult to change, but they try to monopolize the market is impossible. The reason is also very clear, the technology is constantly improving, the new needs of the industrial market emerge endlessly, especially the rapid development of the industrial Internet and intelligent manufacturing for the replacement of PLC, function expansion has built a lot of space; There are many market segments around the bulk PLC market that require deep cultivation and complete solutions. Therefore, to establish the ecology of China’s domestic PLC market, we must discuss and practice from the strategy, ideas and methods.

Imported PLC occupies the majority of the domestic PLC market, there are historical reasons. In the 1980s and 1990s, when there was no ability to provide PLC in China, the PLC application market was driven by PLC manufacturers such as the United States, Germany, Japan and France. To have a certain market size, and customers have formed a dependence on inertia, technical support capabilities, application personnel training and savings have become an important way of competition. Since the 1990s, Siemens, Rockwell, Mitsubishi Electric, etc., have donated or provided PLC experimental equipment to engineering universities in batches, sought and cultivated university teachers who wrote PLC professional textbooks for related models, and cooperated with relevant publishing houses to publish a large number of PLC books. The fundamental reason for this strategy is to hope that the domestic formation will only use, will not design and manufacture PLC market situation. In the short term, this way is profitable for both sides, and in the long term, it sets a heavy threshold for the development of domestic PLC talents, application habits and preferences. Although the domestic people of insight and PLCopen China organization have been calling for and promoting the general education based on the international standard IEC 61131-3 PLC programming language for many years, and have achieved certain results; However, let the majority of engineering students and on-the-job technical personnel master the basic theoretical knowledge of PLC, change the PLC curriculum with the model as the core, and have not made a breakthrough in a large area, and have not fundamentally solved the problem. To break the long-term dependence on imported PLC inertia, it is necessary to start from the reserve team of PLC application engineers, the need for a systematic approach or the formation of a virtuous cycle of ecosystems, the need for long-term unremitting efforts.

Market expansion may wish to seek a breakthrough from the PLC OEM market. In general, for small and medium-sized PLC OEM demand accounted for more than 60%, the factor to win market share is to meet the requirements of OEM manufacturers from the rationality and economy of configuration, rapid response, quality, price and other aspects. It should be said that flexibility is the advantage of domestic PLC manufacturers, and embedded customized PLC as a response method is a very suitable option; At the same time, stable quality is the goal that domestic manufacturers must ensure. In recent years, many domestic PLC manufacturers can survive and develop, and the experience is to develop and serve the segmented industries and markets. For example, during the outbreak of the new coronavirus, the demand for mask production lines or equipment has suddenly increased a lot, and the delivery time of imported PLC is delayed due to chip and other reasons, such a relatively simple PLC system can be met domestically, giving domestic PLC some opportunities, but it is obvious that such opportunistic demand will not last.
