· Programmable logic devices are standard off-the-shelf components that can offer customers a wide variety of logic capacities, features, and speeds.
· Many people think that programmable array logic is a low-integration chip, not only the knowledge is obscure, but the market development space is limited. But is this really the case?
· In 2021, the control logic programmable motor protector developed by many companies will be applied in the chemical industry.
· On the other hand, Rockwell (AB, the United States), a global industry veteran industrial automation and information manufacturer, issued a price increase notice. Among them, the prices of PLC (programmable logic controller) product series have been greatly increased, and most products have increased by more than 10%. CLX1756 -The single price increase of L8SP product series is as high as 36%. In addition, it is also reported that the prices of the product series of major PLC manufacturers have skyrocketed recently, and a large number of companies have benefited from the rapid growth of substitution and demand. The supply time of mainstream brands is as long as 8 months.
· So, does this mean that the "industrial brain" PLC has become a scarce product?
· PLC can be called the "brain" of the industry. It uses a type of programmable memory to store programs, perform logic operations, sequence control, etc., and control various types of machinery or production processes through digital or analog input/output. These programmable logic controllers are used in the entire iron and steel smelting and processing production lines from raw material docks to blast furnaces, steel rolling, steel pipes, etc., replacing traditional relay logic systems, and partially replacing analog control and small DDC systems.
· The most noteworthy PLC products in the automation industry are: ABBAC500-XC programmable logic controller PLC, Panasonic AFPX-C40R-F, FP-XC40RPLC programmable controller, GE intelligent platform VersaMaxMicro controller and so on. In the automation industry, a very classic PLC case is: use PLC to control the five-position automatic cycle of the trolley to run back and forth. In many classic cases, the design of the touch screen unit is very ingenious. It uses a 7-inch color touch screen, which is mainly used for PLC host Ethernet communication to control and display the operating status of each unit.
