PLC (Programmable Logic Controller) applications in life are as follows:
1, industrial automation control: PLC is widely used in industrial automation control, such as production lines, robots, automated assembly lines.
2, building automation control: PLC can be used in building automation control, such as lighting control, air conditioning control, access control system.
3, intelligent home control: PLC can be used for intelligent home control, such as home theater, music system, home security systems.
4, traffic signal control: PLC can be used in traffic signal control, such as traffic light control, railroad signal control.
5, water treatment system control: PLC can be used in water treatment systems, such as pump control, water level control, water quality monitoring.
6, medical equipment control: PLC can be used for medical equipment control, such as surgical equipment, medical monitoring systems.
7, environmental monitoring control: PLC can be used for environmental monitoring control, such as weather stations, pollution monitoring.
PLC is an abbreviation for Programmable Logic Controller, a computer control system specially designed for industrial automation and control.PLC is able to control and automate the operation of a machine or a production line according to the preset programs and input signals.
The PLC system usually consists of three basic parts: an input module, a central processor and an output module.
Inventor of the PLC
The inventor of the PLC (Programmable Logic Controller) was Dick Morley, an engineer at the American company Modicon (now Schneider Electric).
In 1970, while designing an automation system for a beverage company, Morley Morley was designing an automation system for a beverage company in 1970 when he realized that traditional relay control systems were plagued with problems, such as low reliability, difficult maintenance, and high costs. In order to solve these problems, Morley proposed a new type of automation control system based on programmable logic controllers, which is PLC.
Because PLC has the advantages of programmability, flexibility, and reliability, it was soon widely used in industry. With the passage of time, PLC technology continues to develop and improve, becoming one of the important technologies in the field of modern industrial automation and control.
