Tutto sui PLC: la CPU
A practical engineering guide to PLC CPU operation, from deterministic scan cycles and I/O image tables to memory, communications, diagnostics, redundancy, processor sizing, and reliable system...
Designed for robust data retention and program storage within legacy control architectures, the Schneider Electric TSXMRPC01M7 provides configurable SRAM storage for Modicon Quantum automation systems. This PCMCIA Type I card ensures non-volatile memory allocation for critical application logic and register data, serving as a direct functional replacement for legacy storage modules in industrial environments.
| Parameter | Specification |

| Memory Capacity | 1.7 MB (Unity Pro) / Replaces 256k words (PL7) |
| Form Factor | PCMCIA Type I |
| Legacy Replacement | TSXMRP3256P |
| Commodity Code | 85389091 |
| ECCN | N |
| Shipping Weight (Calculated) | 0.30 kg |
| Package Dimensions (Calculated) | 9.0 x 13.0 x 3.0 cm |
The TSXMRPC01M7 is backward-compatible with older PL7 applications, functioning as a direct drop-in replacement for the discontinued TSXMRP3256P. When migrating configurations from PL7 to Unity Pro, the memory allocation changes from word-based addressing to standard byte-based addressing, utilizing the full 1.7MB capacity.
Because this card utilizes volatile SRAM technology to maintain high-speed access, it relies entirely on auxiliary battery backup to retain data when the PLC rack is powered down. If the CPU battery or the card's internal battery cell is depleted during a power outage, the stored application program and register configurations will be lost. Implement a strict preventative maintenance schedule to replace system batteries before they reach critical discharge levels.
Before inserting the card, inspect the 68-pin female connector on the PCMCIA slot for any bent pins. Ensure the card is oriented correctly; forcing the card into the slot backward can cause permanent physical damage to the CPU's internal interface pins.
CRITICAL WARNING
Do not insert or remove the PCMCIA memory card while the CPU is actively reading or writing data (indicated by the memory access LED). Hot-swapping the card during active operations can cause immediate firmware corruption, system halt, or physical damage to the SRAM sectors.
Power down the Modicon Quantum rack or verify that the CPU is in a safe, stopped state with no memory access active.
Align the TSXMRPC01M7 card with the guide rails of the PCMCIA slot on the front panel of the Quantum CPU.
Gently slide the card inward until the connector is fully seated and the eject button pops out to its locked position.
Power up the rack and verify card recognition and memory allocation status via your programming software (Unity Pro or PL7).
