Integrated PLC Integrated PLC is a kind of integrated PLC that integrates power supply, CPU, I/O interface and other components into a cabinet, which is characterized by compact structure, small size and low price. Small PLC generally adopts this integral structure. The integrated PLC is composed of basic units (also known as host) and expansion units with different I/O points. The basic unit includes CPU, I/O interface, expansion interface connected with I/O expansion unit, and interface connected with programmer or EPROM writer. There is only I/O and power supply in the expansion unit, without CPU. The basic unit and expansion unit are generally connected with flat cables. The integrated PLC can also be equipped with special functional units, such as analog unit, position control unit, etc., to expand its functions.

The memory of the programmable controller is composed of three parts: read-only memory ROM, random access memory RAM and electrically erasable memory EEPROM. It is mainly used to store system programs, user programs and working data.

The read-only memory ROM is used to store the system program. The programmable controller fixes the system program in the ROM during the production process, and the user cannot change it. Among the random access memory RAM for storing user programs and intermediate operation data, RAM memory is a kind of semiconductor memory with high density, low power consumption and low price, which can be used as a backup power supply by lithium battery. The content stored in it is volatile and will be lost after power failure; When the system is powered down, user programs can be saved in read-only memory EEPROM or RAM supported by high-energy batteries. EEPROM combines the advantages of non-volatile ROM and random access of RAM, and is used to store important data that need to be stored for a long time.
