Product Details
***The processing unit (CPU) is the control center of the PLC and serves as the central nervous system. Each PLC has at least one CPU. It receives and stores user programs and data input from the programmer according to the functions assigned by the PLC system program; Check the status of power supply, memory, I/O and alert timer, and diagnose Syntax error in user program. When the PLC is put into operation, it first receives the status and data of various input devices on site through scanning, and stores them in the I/O image area respectively. Then, it reads user programs one by one from the user program memory, interprets commands, and executes logical or arithmetic operations according to the instructions. The results are sent to the I/O image area or data register. After all user programs are executed, * * * transfers the output states or data in the output registers of the I/O image area to the corresponding output devices, and runs in a loop until it stops running.
In order to further improve the reliability of PLCs, redundant systems with dual CPUs or voting systems with three CPUs are also used for large PLCs. In this way, even if a CPU fails, the entire system can still operate normally.
CPU speed and memory capacity are important parameters of PLC, which determine the working speed, I/O quantity, and software capacity of PLC, thus limiting the control scale.
storage
System program memory is the memory that stores system software; The user program memory is used to store PLC user program applications; Data storage is used to store intermediate states and information during the execution of PLC programs, which is equivalent to the memory of a PC.
Input output interface (I/O module)
The interface between PLC and electrical circuit is completed through the input and output part (I/O). The I/O module integrates the I/O circuit of the PLC, with the input register reflecting the status of the input signal and the output point reflecting the status of the output latch. The input module converts electrical signals into digital signals and enters the PLC system, while the output module is the opposite. I/O is divided into modules such as switch input (DI), switch output (DO), analog input (AI), and analog output (AO).
communication interface
The main function of the communication interface is to achieve data exchange (communication) between the PLC and external devices. There are various forms of communication interfaces, including standard serial interfaces such as UBS, RS-232, RS-422/RS-485, etc. It can be connected through multi-core cables, twisted pair cables, coaxial cables, optical cables, etc.
source
The power supply of PLC provides working power for the PLC circuit and plays a very important role in the entire system. A good and reliable power system is the basic guarantee of PLC. Generally, the fluctuation of AC voltage is within the range of+10% (+15%), and the PLC can be directly connected to the AC power grid without taking other measures. The types of power input include: AC power supply (220VAC or 110VAC), DC power supply (commonly used as 24VDC).
