  • Functional Features:
    • 4 MB dual-partitioned SLC Flash memory provides dedicated high-capacity storage for PLC control programs and process data, enabling complex control logic and long-term data logging without memory limitations. Industrial-grade SLC NAND Flash technology delivers superior reliability, speed and data retention compared to MLC Flash, with >15 years of non-volatile data retention (no battery required), eliminating battery replacement maintenance and data loss from battery failure. High-speed read/write access (<40 ns read / <80 μs write) ensures real-time PLC operation, with no latency in program execution or data retrieval for fast-dynamic control and high-speed data logging applications. Automatic memory detection and allocation by the PLC CPU enables plug-and-play installation, with no complex configuration required for basic operation; user-configurable partitioning via programming software allows customization for specific application needs (e.g., more program memory or more data logging memory). The 10 Mbps high-speed backplane interface ensures fast data transfer between the memory module and PLC CPU, critical for high-speed data logging and recipe management applications with frequent data access. The module’s low power consumption reduces overall PLC chassis power draw, complying with industrial energy efficiency standards and minimizing heat generation in control cabinets. Rugged industrial design with wide temperature tolerance and vibration/shock resistance ensures reliable operation in harsh industrial environments, including high-temperature control cabinets, mining sites and marine applications. Support for multiple critical PLC functions (program storage, data logging, recipe management, alarm logging) in a single module eliminates the need for multiple memory components, reducing system complexity and hardware costs. The compact standard Modicon slot form factor enables easy installation in existing PLC chassis, with no additional space required for memory expansion. Non-volatile storage retains all program and data information during power outages, ensuring the PLC system restarts quickly and resumes normal operation without data loss or program corruption.
  • Application Scenarios:
    • Memory expansion for Modicon 984/900 series PLCs in complex industrial automation applications (e.g., automotive assembly lines) with large, multi-layer control programs. Long-term process data logging in chemical and petrochemical processing plants, storing months of flow, pressure, temperature and level data for compliance and process optimization. Recipe management in large-scale food and beverage and pharmaceutical manufacturing, storing thousands of production recipes for batch process control and GMP compliance. Alarm event logging in power generation and distribution facilities, storing critical system fault and alarm data for root cause analysis and preventative maintenance. Memory expansion for legacy Modicon 984 series PLC systems, extending the service life and functionality of existing automation equipment. High-speed data logging in packaging and electronics manufacturing, storing real-time production and quality control data for process improvement. Remote PLC systems in oil and gas pipeline monitoring, storing program and data locally for reliable operation even during communication link loss. Mining and mineral processing PLC systems, with rugged non-volatile memory for reliable operation in remote, harsh mine sites with frequent power fluctuations. Marine and offshore PLC installations, with no-battery data retention for reliable operation in salt-laden and vibration-prone shipboard and platform environments.
