In addition, in discrete event systems, such as highway network traffic flow (vehicle counting, passenger counting, and residence time measurement), logistics systems, flexible manufacturing systems (agile manufacturing systems), and all non-standard on-demand service systems, PLC can be used to model, take countermeasures, and optimize. The future of PLC is promising, and all pessimistic arguments are untenable. As for technological progress, it will take some time for PLC to integrate with other technologies and even disappear!
As is well known, since the 1960s, Western countries have relied on technological advancements (i.e. new equipment, new processes, and computer applications) to transform traditional industries, resulting in rapid industrial development. The biggest change in the world at the end of the 20th century was the formation of global markets.
The global market has led to unprecedented fierce competition, prompting enterprises to accelerate the time to market for new products, improve quality, reduce costs, and improve service systems. This is the T.Q.C.S. of enterpriAlthough computer integrated manufacturing system (CIMS) combines information integration and system integration to pursue more perfect T.Q.C.S., it enables enterprises to “transmit the right information to the right people in the right way at the right time, so as to make the right decision”, that is, “Five Corrects”
However, this automation requires a significant investment and is a high investment, cost-effective, and high-risk development model that is difficult for most small and medium-sized enterprises to adopt. In China, small and medium-sized enterprises and quasi large enterprises still follow the path of low-cost industrial control automation.automatioIndustrial control automation mainly consists of three levels, from bottom to top are basic automation
process automation, and management automation, with the core being basic automation and process automation.
In traditional automation systems, the basic automation part is basically monopolized by PLC and DCS, while the process automation and management automation parts are mainly composed of various imported process computers or small computers. The high prices of their hardware, system software, and application software make many enterprises hesitant.
