Schneider TSXMRPC002M Modicon Premium SRAM Memory Card

The Schneider Electric TSXMRPC002M, also cataloged as the TSXMRPC002M Memory Extension, operates as a dedicated hardware component for volatile application scaling and variable data storage expansion within Schneider Electric Modicon Premium automation platforms. The plug-in PCMCIA card inserts directly into the central processor slot to extend the local memory boundaries required for large-scale control logic execution and recipe storage arrays.

Hardware Specifications

Modicon Premium Automation Framework

• Backplane Bus Communication Velocity and Memory Integration: The SRAM extension card couples directly to the host CPU's internal memory bus structure. It permits real-time program execution and register manipulation at native backplane communication velocity, eliminating transmission delays when parsing expanded application blocks.
• I/O Density Scaling Memory Matrix: The card expands the memory map to manage the higher processing overhead associated with widespread I/O density scaling. The configurable memory partition lets system engineers allocate memory resources between active task execution logic and static internal data registers.

Frequently Asked Questions

Q: Can the TSXMRPC002M card be inserted or pulled while the host processor is powered up?

A: No. The Modicon Premium physical slot architecture does not support live hot-swapping of memory components. Extracting or unseating this SRAM card while the CPU is energized will cause an instantaneous memory bus crash, corrupt active data variables, and trigger a fatal processor stop fault.

Q: How is data volatility managed when the primary PLC rack power is disconnected?

A: Because standard SRAM blocks require constant electrical bias to retain binary states, data preservation during a main power drop depends on a functional backup battery. This battery is housed within the main Modicon Premium processor module or embedded on the card subassembly to prevent program loss during panel shutdowns.

Field Installation Guidelines

• Chassis Layout Alignment, Clearance Constraints, and Mechanical Seating: Isolate the main power feeds to the TSX RKY rack subframe before opening the CPU memory port. Align the 0.07 lbs card straight with the Slot 0 guide rails, then press firmly until the multi-pin connector seats completely flush into the internal mating receptacle. Close the protective mechanical latch cover.
• Conductor Separation, Wireway Constraints, and Anti-Static Guarding: Since memory cards are highly susceptible to permanent electrostatic discharge (ESD) degradation, operators must wear a grounded wrist strap or touch a structural metal panel ground bar prior to handling the module. Store uninstalled cards inside anti-static shielding bags away from external electromagnetic fields.
