6ES7953-8LJ31-0AA0 Siemens SIMATIC S7 Micro Memory Card

Product parameters

Electrical parameters: The working voltage is 3.3V, and it adopts an Nflash storage chip.

Performance parameters: The storage capacity is 512KB. As a storage device for PLC, it can meet the requirements of basic program and data storage.

Environmental parameters: Compatible with common working conditions in industrial environments and possessing a certain degree of environmental adaptability.

Function

Program and data storage: As the loading memory for Siemens S7-300 and other series PLCS, it is specifically designed to store user programs, including symbols, annotations and other contents within the programs. At the same time, it can store key information such as formula data and process data generated during the operation of the PLC, providing data storage support for the operation of the PLC.

Stable data retention: It has a reliable ability to retain data after power failure. When the equipment suddenly loses power, the CPU of the PLC will automatically write all retained data to this memory card. After power is restored, the data remains unchanged. Data backup can be achieved without additional maintenance, reducing the risk of data loss caused by power failure.

Compatibility and convenience: Designed for Siemens S7-300/C7/ET200 series devices, it has strong compatibility and can ensure the stability of data transmission and storage. The operation is convenient. When replacing the CPU, just insert this memory card and the program will be automatically transferred without the need for a programmer, which improves the efficiency of equipment maintenance and replacement.

Security and diagnostic assistance: Supports user program password protection function, which can effectively prevent programs from being illegally accessed, modified or copied, ensuring program security. It can simultaneously store faults and interruption events during the operation of the PLC, providing diagnostic data support for equipment fault detection and later maintenance.

Application scenarios

Manufacturing production lines: In various manufacturing production lines, it is used in conjunction with the S7-300 series PLC to store the control programs of the production line, such as the movement logic of the robotic arm, the operation parameter Settings of the conveyor belt, and the control instructions of the production process, ensuring that the production line operates automatically according to the preset process, thereby enhancing production efficiency and accuracy.

Industrial equipment control system: It is a control system applicable to various types of industrial equipment, such as control units of machine tools, textile machinery, printing equipment, etc. It stores the control programs and operation data of the equipment, ensuring stable and precise operation of the equipment and reducing equipment downtime caused by program loss or abnormal data.

Building automation system: In the field of building automation, it can be used to store the control programs of building equipment and related energy consumption data, such as the start and stop control logic of central air conditioning systems, temperature regulation parameters, and the switch sequence programs of lighting systems, etc. It helps building management systems achieve intelligent regulation and control of various equipment, optimize energy consumption, and improve building management efficiency.

In the field of energy and infrastructure: In the monitoring and control systems of energy and infrastructure industries such as power and water treatment, the operation control programs and monitoring data of equipment are stored, such as the operation status monitoring programs of power equipment and the process flow control data of water treatment equipment, providing data support for the stable operation of the system and the later energy optimization allocation and equipment maintenance.
