Expanding Modicon Premium Capabilities

The Schneider Electric TSXMFPP128K is a specialized Flash EPROM memory module designed to enhance the processing power and storage capacity of the Modicon Premium automation platform. As industrial processes grow in complexity, standard internal memory often reaches its limits. This memory extension allows engineers to store larger application programs, extensive symbol tables, and critical configuration data directly on the processor.

Schneider Electric engineered this module specifically for the TSX Micro and Modicon Premium series. It serves as a reliable repository for PLC logic, ensuring that the system executes complex automation tasks without hardware bottlenecks. By offloading application data to this external Flash EPROM, the processor maintains peak performance even during high-intensity logic cycles.

Technical Specifications

The TSXMFPP128K offers a precise balance of capacity and industrial-grade reliability. The following table summarizes the essential technical data for this memory module:

Flash EPROM Technology Advantages

The TSXMFPP128K utilizes Flash EPROM (Electrically Erasable Programmable Read-Only Memory) technology. This choice of storage medium provides several distinct advantages for industrial automation:

• Non-Volatile Storage: Unlike standard RAM, Flash EPROM does not require a battery to retain data. Even during a complete power failure or long-term storage, the application program remains safe within the module. This eliminates the risk of program loss due to battery depletion.
• Fast Read Access: The processor can access the data stored on the TSXMFPP128K at high speeds, ensuring that the PLC scan time remains within strict industrial limits.
• Reliable Re-programmability: Maintenance teams can overwrite the memory multiple times as process requirements change, providing a cost-effective solution for evolving production lines.

Wide Processor Compatibility

Schneider Electric designed the TSXMFPP128K for maximum versatility across the Modicon Premium ecosystem. It integrates seamlessly with a wide array of processors, making it a staple spare part for many facilities. Compatible processor families include:

1. TSX570 to TSX574 Series: Supports the standard range of Modicon Premium controllers used in discrete manufacturing.
2. TSX57C Series: Compatible with compact Premium processors.
3. TSXPCI572/3 Series: Works with PC-based control cards, allowing for unified memory management across different hardware formats.

The module fits exclusively into Slot 0 of the compatible processor. This dedicated slot ensures that the memory extension does not interfere with other communication or I/O expansion modules.

Industrial Durability and Environmental Compliance

The TSXMFPP128K thrives in demanding factory environments. Schneider Electric built this module to withstand significant mechanical stress, including 15 gn of shock and continuous vibration. Such durability is essential for PLCs mounted on or near heavy machinery where constant movement is a factor.

Furthermore, the module operates in a broad temperature range from -25°C to +70°C. This allows for installation in unconditioned control cabinets or outdoor enclosures in varied climates. As a Green Premium product, the TSXMFPP128K also meets strict RoHS environmental standards, ensuring that the hardware is free from hazardous substances and follows sustainable manufacturing practices.

Installation and Maintenance

The compact physical dimensions (3.0 x 9.5 x 5.31 cm) and lightweight design (0.044 kg) make the TSXMFPP128K easy to handle. To install the module, the technician simply inserts it into Slot 0 of the processor while the power is off. The secure locking mechanism prevents the card from loosening due to vibration.

Because the module uses Flash technology, it requires virtually no maintenance once installed. It provides a “fit and forget” solution for application backup. For facilities running legacy TSX Micro or Modicon Premium systems, keeping a TSXMFPP128K in stock is a smart strategy to ensure rapid recovery in the event of hardware replacement.
