The memory in the PLC system is mainly used to store system programs, user programs, and work status data. The memory of PLC includes system memory and user memory.
(1) System memory
The system memory is used to store the system program written by the PLC manufacturer and is fixed in the ROM, which cannot be changed by the user. It endows PLC with fundamental functionality and enables the completion of various tasks according to the rules of PLC designers. The quality of the system program largely determines the functionality of the PLC.
(2) User Memory
User memory includes two parts: user program memory (program area) and data memory (data area). The user program memory is used to store various user programs written in PLC programming language for detailed control tasks. The user program memory can be modified or added or deleted by the user depending on the type of memory unit selected (such as RAM, EPROM, or EEPROM memory). User data storage can be used to store (recall) the ON/OFF status and data of devices used in user programs. The size of user memory is related to the capacity of user programs and is one of the main objectives reflecting PLC functionality.
In order to facilitate reading, viewing, and correction, user programs are usually stored in CMOS static RAM, using lithium batteries as backup power to ensure that information is not lost during power outages. In order to avoid damage to the program in RAM caused by interference, when the user program runs normally and does not need to be changed, it can be fixed in the read-only memory EPROM. Nowadays, many PLCs directly choose EEPROM as their user memory.
Work data is some data that is frequently changed and accessed during the operation of PLC. Registered in RAM to accommodate random access requests. In the working data memory of PLC, there is a storage area for storing logic devices such as input/output relays, auxiliary relays, timers, counters, etc. The condition of these devices is determined by the initial settings and operating conditions of the user program. As needed, some data can be maintained in its current condition using a backup battery during power outages, and the storage area where data can be saved during power outages is called the data retention area.
Because the system program and working data are not directly linked to the user, the form and capacity of the memory listed in the PLC product samples or user manuals refer to the user program memory. When the user memory capacity provided by the PLC is insufficient, many PLCs also provide memory expansion functions.
There are mainly two types of memory: one is random access memory (RAM) for read/write operations, and the other is read-only memory or erasable programmable read-only memory (ROM), PROM, EPROM, and EEPROM.

The function of PLC control switch quantity is very strong. The number of input and output points controlled can range from a few dozen or tens of points, to several hundred, thousands, or even tens of thousands, because it can be connected to the internet, and the number of points is simply unrestricted. No matter how many points can be controlled, the logic questions controlled can be various: combination, timing, real-time, delayed, non counting, counting required, fixed order, random operation, and so on, all of which can be carried out.
The hardware structure of PLC is variable, and the software program is programmable, making it very flexible when used for control. If necessary, multiple sets or groups of programs can be written and called according to requirements. It is accustomed to the need for multiple working conditions and changes in industrial sites.
There are many examples of using PLC for switch quantity control, such as metallurgy, machinery, light industry, chemical industry, textile, and so on, which are needed in almost all industrial industries. Nowadays, the primary principle of PLC is that it can be easily and reliably used for switch control, which cannot be compared with other controllers.
2. Used for analog control
Analog quantities, such as current, voltage, temperature, pressure, etc., are constantly changing in size. Industrial production, especially continuous production processes, often requires control over these physical quantities.
As an industrial control electronic device, if PLC cannot control these quantities, it is a major deficiency. Therefore, various PLC manufacturers have made many developments in this area. Nowadays, not only large and medium-sized computers can perform analog control, even small computers can also perform such control. PLC for analog control should be equipped with A/D and D/A units that convert analog and digital signals into each other. It is also an I/O unit, but it is a special I/O unit.
The A/D unit converts analog signals from external circuits into digital signals and sends them to the PLC; The D/A unit converts the digital signal of the PLC into an analog signal and sends it to the external circuit. As a special type of I/O unit, it still has characteristics such as anti-interference of I/O circuits, blocking of internal and external circuits, and communication of information with input/output relays (or internal relays, which are also an area of PLC operating memory for reading and writing).
The A in A/D here is mostly current, voltage, and also temperature. A in D/A is mostly voltage or current. The scale of voltage and current changes is mostly 0-5V, 0-10V, 4-20mA, and some can also handle positive and negative values. The D here is mostly an 8-bit binary number for small computers, and a 12 bit binary number for medium and large computers
