The system program belongs to the important data to be stored for a long time, so its memory uses ROM or EPROM. ROM is a read-only memory. The memory can only read the content, but cannot write the content. ROM is non-volatile, that is, it can still save the stored content after the power is disconnected.

EPEROM is electrically erasable read-only memory, which can erase the written content only by irradiating the lens window on the chip with ultraviolet light. Programmable read-only memory can be electrically erased, including E2PROM, FLASH, etc.

2) User program memory

The user program memory is used to store the PLC application program loaded by the user. The user program at the beginning of loading needs to be modified and debugged, so it is called the user debugger. It is stored in the random access memory RAM that can be randomly read and write to facilitate the user to modify and debug.

The program after modification and debugging is called the user execution program, because there is no need to modify and debug, so the user execution program is solidified into the EPROM for long-term use.

3) Data storage

In the process of PLC operation, intermediate result data (such as input/output component status data, timer, counter preset value and current value, etc.) and configuration data (such as input and output configuration, input filtering Settings, pulse capture, output table configuration, define storage area hold range, analog potential device Settings, high-speed counter configuration, high-speed pulse output configuration, pass Information configuration, etc.), such data is stored in the working data memory. Since the working data and configuration data are constantly changing and do not need to be stored for a long time, random access memory RAM is used.

RAM is a type of semiconductor memory with high density and low power consumption. Lithium batteries can be used as a backup power source. In case of power failure, the contents of RAM can be maintained through lithium batteries.
