4. PLC and its related peripherals should be designed according to the principle that it is easy to form a whole with the industrial control system and expand its functions. The basic composition overview of PLC is divided into two types: fixed and modular (modular).
1. PLC control system is a new generation of industrial control devices formed by introducing microelectronic technology, computer technology, automatic control technology and communication technology on the basis of traditional sequential controllers. The purpose is to replace relay, execution logic, timing, counting and other sequential control functions. , establish a flexible remote control system.
2. PLC control system is a Programmable Logic Controller (PLC) launched in the United States in the 1960s.
3. Programmable control system) PLC* is a microcomputer-based control system. It is developed on the basis of computer and relay control technology, performing functions such as logic, sequencing, timing, calculation, etc., and is widely used in the automatic control of mechanical equipment and assembly line production processes.
4. PLC generally refers to a programmable logic controller. The function is: logical control of switching quantity. This is the most basic and extensive application field of PLC. It replaces the traditional relay circuit to realize logic control and sequence control. It can be used not only for the control of a single device, but also for multi-machine group control and automated assembly lines.
5. PLC control system: Programmable logic controller (PLC), which adopts a kind of programmable memory, is used for its internal storage program, executes user-oriented instructions such as logical operation, sequence control, timing, counting and arithmetic operations, and controls through digital or analog input/output Produce various types of machinery or production processes.
6. PLC is a power line communication, which uses modular signals to provide broadband data communication on conductors that have been used for power transmission. The use of PLC technology includes sending radio programs, utility company control switching mechanism, transmission line protection and automatic meter reading.
