Technical Specifications
- Memory Capacity: Available in four versions: 64KB, 128KB, 256KB, and 512KB.
- Power – off Memory Retention: Retained by a lithium – battery (IC697ACC701). The battery shelf life is 10 years at 20°C. Without power, the memory can be retained for about 6 months.
Function Features
- Easy Installation: No tools are required during the installation process, and it can be easily installed in the field.
- Error – checking: The logic program memory is continuously error – checked by the PLC CPU as a background task. The PCM also checks the storage memory when power is cycled and during hard or soft resets.
- Configurable for Data and Program Retention: It can be configured to retain data and programs, ensuring the safety of user – stored information.
Application Scenarios
- Industrial Automation Control Systems: In industrial production lines, it can be used to expand the memory of PLCs, enabling more complex control logic and data storage, such as controlling the operation of conveyor belts, robotic arms, and other equipment in manufacturing plants.
- Process Control in Various Industries: Such as in the chemical, petroleum, and power industries, it helps PLCs to store more process – related data and control programs, so as to accurately monitor and control process parameters such as temperature, pressure, and flow rate.
