Product Details
The Schneider Electric TSXMRPC003M, also cataloged as the TSXMRPC003M SRAM Memory Extension, operates as a dedicated hardware component for volatile application execution and data storage retention within Modicon Premium automation processors. Inserted directly into processor Slot 0, it expands memory capacity across TSX57 series CPU architectures to support real-time execution of PL7 Pro/Unity logic programs and user data tables.

Backplane Bus Communication Velocity and Firmware Compatibility
The Modicon Premium SRAM memory card communicates directly over the internal high-speed processor bus interface. Access latencies are minimized to prevent execution stalls during cyclic and event-driven task scanning. Firmware flash compatibility between the host TSX57 processor core and the memory module ensures deterministic memory mapping, allowing dynamic re-allocation of application logic and file storage segments without corrupting backplane synchronization protocols.
Frequently Asked Questions
Q: Can the TSXMRPC003M memory card be inserted or removed while the CPU is powered?
A: No. Hot-swapping memory cards in Slot 0 during active operation can corrupt the processor memory bus and trip host CPU fault latches. Control power to the rack must be switched off prior to card insertion or removal.
Q: How is data retained in the SRAM module during a main supply outage?
A: Non-volatile retention relies on the internal battery backup circuit provided by the host TSX57 processor assembly. Maintaining valid battery voltage is necessary to preserve configured data blocks when power is removed from the rack.
Q: How is memory partitioned between program application space and data storage?
A: The total SRAM capacity is user-configurable within programming software, allowing allocation up to 3072 kB for application logic or shifting up to 2880 kB toward file and variable data storage.
Field Installation Guidelines
- Remove main AC/DC power from the Modicon Premium rack housing the target TSX57 processor.
- Locate the designated PCMCIA Slot 0 connector on the front panel of the processor unit.
- Align the TSXMRPC003M card with the card guide tracks of Slot 0, ensuring correct orientation of the rear multipin bus interface.
- Press the card firmly into the slot until the mechanical locking latch engages and the card seats flush against the processor bezel.
- Apply power to the rack and verify via status diagnostics in the programming software that the expanded SRAM card is recognized.
- Store unused memory cards in anti-static protective packaging to prevent electrostatic discharge damage to internal CMOS RAM cells.

Comprehensive Guide to Noise Types in Industrial Automation and Electronics
Mitigating Emergency Stop Spurious Trips in Industrial Control Systems
Emergency stop (E-Stop) pushbuttons serve as vital safety devices in factory automation and process control plants. Functional safety standards mandate normally-closed (NC) contact blocks to ensure fail-safe operation during wiring breaks or power outages. However, mechanical degradation over time can trigger unexpected spurious trips, halting production lines without an actual emergency. Understanding the underlying causes of mechanical contact failure allows automation engineers to implement robust, fault-tolerant safety circuits.
Redundant Automation Systems: Maximizing Uptime in Critical Control Applications
Industrial automation relies on continuous operational stability to prevent catastrophic downtime and financial loss. While standard dictionary definitions treat redundancy as superfluous, industrial engineers consider redundant control architectures indispensable for high-availability systems. Implementing backup hardware ensures seamless takeover during primary equipment failures, protecting critical infrastructure across manufacturing and process industries.
