Providing critical storage expansion for legacy industrial controllers, this Schneider Electric TSXMCPC002M PCMCIA card delivers reliable application and data backup capabilities. Engineered specifically for legacy Modicon Premium and Modicon Quantum automation platforms, this memory expansion card ensures system stability and program retention in demanding industrial environments. By combining Flash EPROM and SRAM technologies, it provides a dual-purpose storage architecture designed to preserve both active control logic and dynamic process variables during power cycles.
Key Features
-
Dual-Storage Architecture: Allocates 2 MB of Flash EPROM for application program storage and 1 MB of SRAM for dynamic data variables.
-
PCMCIA Form Factor: Standardized physical interface ensures direct, secure insertion into compatible PLC controller slots.
-
Legacy System Support: Crucial hardware component for maintaining, upgrading, or restoring phased-out Modicon Premium and Quantum control systems.
-
Robust Data Retention: Designed to prevent program loss during extended system shutdowns or main power interruptions.
Applications
- Legacy Modicon Premium and Modicon Quantum PLC systems.
- Industrial manufacturing execution systems requiring local recipe and configuration storage.
- Water treatment, infrastructure, and legacy process automation panels.

Alternative Models & Compatibility
The TSXMCPC002M serves as a direct replacement or upgrade path for lower-capacity memory cards within the Modicon Premium and Quantum families. When migrating from smaller cards, verify that the target CPU firmware supports the expanded 2 MB application and 1 MB data boundaries. Ensure your programming software (such as PL7 Pro or Unity Pro) is configured for the correct memory allocation model before downloading the application file.
Application Pitfalls & Engineering Notes
Because this card utilizes SRAM for dynamic data storage, continuous data retention during power-off states relies heavily on the health of the backup battery located in either the host CPU or the card itself. If the system is powered down for extended periods with a depleted battery, dynamic variables, registers, and runtime parameters stored in the 1 MB SRAM partition may be lost, while the 2 MB Flash EPROM will safely retain the base application program.
Commissioning & Wiring Tips
Always inspect the PCMCIA slot on the host CPU for dust or bent pins prior to insertion. When inserting the TSXMCPC002M, ensure the card is aligned straight to prevent pin misalignment. Do not force the card into the slot; it should slide in smoothly and click into place when fully seated.
Installation Guidelines
CRITICAL WARNING
Never insert or remove the memory card while the PLC rack is powered on. Hot-swapping the PCMCIA card can cause immediate CPU faults, permanent memory sector corruption, or physical damage to the card's internal circuitry.
1
Completely de-energize the PLC rack and verify that all status LEDs on the CPU module are completely off.
2
Align the TSXMCPC002M card with the guide rails of the designated PCMCIA slot on the controller.
3
Gently push the card into the slot until the eject button pops out, indicating a secure mechanical and electrical connection.
4
Restore power to the rack and verify via your programming software that the memory expansion card is recognized and healthy.
