1. The composition of PLC
    From the structure point of view, PLC is divided into two types: fixed type and combined type (module type). Fixed PLC includes CPU board, I/O board, display panel, memory block, power supply, etc. These elements are combined into a non-removable whole. Modular PLC includes CPU modules, I/O modules, memory, power modules, backplanes or racks. These modules can be combined and configured according to certain rules.
  2. The structure of the CPU
The CPU is the core of the PLC and functions as the nerve center. Each set of PLC has at least one CPU. It receives and stores user programs and data according to the functions given by the PLC system program, and collects the data sent by the on-site input device by scanning. The status or data is stored in the specified register, and at the same time, the working status of the power supply and the PLC internal circuit and the syntax error in the programming process are diagnosed. After entering the operation, the instructions are read one by one from the user program memory, and after analysis, the corresponding control signals are generated according to the tasks specified by the instructions to command the relevant control circuits.
   The CPU is mainly composed of arithmetic units, controllers, registers and the data, control and status buses between them. The CPU unit also includes peripheral chips, bus interfaces and related circuits. Memory is mainly used to store programs and data, and is an indispensable unit of PLC.
  In the eyes of the user, it is unnecessary to analyze the internal circuit of the CPU in detail, but there should be enough understanding of the working mechanism of each part. The controller of the CPU controls the work of the CPU, which reads instructions, interprets instructions, and executes instructions. But the working rhythm is controlled by the oscillating signal. The arithmetic unit is used to perform digital or logical operations and work under the command of the controller. The register participates in the operation and stores the intermediate result of the operation. It also works under the command of the controller.
  CPU speed and memory capacity are important parameters of PLC. They determine the working speed of PLC, the number of IOs and software capacity, etc., so they limit the control scale.
  3. I/O module
   The interface between the PLC and the electrical circuit is completed through the input and output part (I/O). The I/O module integrates the I/O circuit of the PLC, and its input register reflects the state of the input signal, and the output point reflects the state of the output latch. The input module transforms the electrical signal into a digital signal and enters the PLC system, while the output module is the opposite. I/O is divided into digital input (DI), digital output (DO), analog input (AI), analog output (AO) and other modules.
   On-off value refers to a signal with only two states of on and off (or 1 and 0), and analog value refers to a continuously changing amount. Commonly used I/O classifications are as follows:
   Switch quantity: according to the voltage level, there are 220VAC, 110VAC, 24VDC, according to the isolation mode, there are relay isolation and transistor isolation.
Analog quantity: According to the signal type, there are current type (4-20mA, 0-20mA), voltage type (0-10V, 0-5V, -10-10V), etc. According to the accuracy, there are 12bit, 14bit, 16bit, etc. .
   In addition to the above-mentioned general IO, there are special IO modules, such as thermal resistance, thermocouple, pulse and other modules.
   Determine the module specifications and quantity according to the number of I/O points. I/O modules can be more or less, but their maximum number is subject to the ability of the basic configuration that the CPU can manage, that is, limited by the maximum number of backplanes or rack slots.
