Choosing NAND flash memory in factory automation systems
NAND flash memory provides high-density storage, fast read and write speeds and is known for its long-term reliability, essential for PLCs, industrial HMIs, robots, cobots and AGVs, which may remain operational in the field for many years.
NAND flash memory for:
- Storage of firmware, software and embedded operating system (OS): This allows for easy updates, maintenance of the device and ensures that it operates correctly.
- Storing system configuration data such as system settings, sensor calibration data, historical data, and other important information.
- NAND flash provides fast access times, which is crucial for real-time data retrieval and display on industrial HMIs. Its durability makes it suitable for industrial environments where shock, vibration, and severe temperature extremes are expected.
- Moreover Industrial HMIs, PLCs, robots, cobots and AGVs often need to log data from sensors, switches, and other input devices as diagnostic information. NAND flash memory provides a reliable and non-volatile storage medium for this data. Sensor data such as images, video, and other sensor readings used to analyze the environment and make decisions based on the data are stored here as well, same as log data which allow to diagnose problems and improve system performance.
- NAND flash incorporates error correction mechanisms to ensure data integrity as well as storage for encryption keys and other security-related data to protect sensitive information on the application (HMI, PLC, robot, cobot, AGV) from unauthorized access or tampering. It can be configured in redundant setups to ensure data redundancy and fault tolerance in critical applications.
KIOXIA NAND flash memory, such as e-MMCs or SLC NAND, is designed for these applications. Moreover, new designs take time and hard work; the memory is rarely changed once approved. That is why longevity needs and future-proofing storage capacity are essential from the start. The different densities allow for the customization of storage capacity to suit appropriate projects.
KIOXIA NAND flash memory is a versatile and reliable storage solution that meets the demanding requirements of industrial HMIs and PLCs, ensuring data integrity and system performance in challenging and harsh industrial environments. It provides a reliable storage solution for critical control and automation applications.
