Product Overview
The Schneider BMXRMS008MP Modicon M340 8MB Memory Card is a removable memory component used with Modicon M340 automation systems for storing PLC application and system data. It provides additional non-volatile storage associated with the controller, allowing application information to be retained separately from the processor’s internal working memory.
In an M340 installation, the memory card is particularly relevant during application backup, processor replacement, commissioning, and maintenance. A correctly configured memory card can simplify the transfer or restoration of application information when servicing a controller.
The card is used as part of the PLC’s memory architecture rather than as an independent processing or communication device. The M340 processor executes the control program, while the memory card serves as a storage medium for supported application and system information.
For maintenance teams, the memory card can be an important part of controller replacement procedures. Its contents, compatibility, and application configuration should be considered when moving an existing M340 application to a replacement processor.

Working Principle
The BMXRMS008MP stores supported application and system information in a removable memory medium associated with the Modicon M340 processor. During normal operation, the processor accesses the stored information according to the M340 system’s memory-management functions.
The card itself does not execute PLC logic. Instead, it provides storage that can be used when an application needs to be retained, transferred, backed up, or restored as part of the controller lifecycle.
M340 Application / System Data ↔ BMXRMS008MP Memory Card ↔ Modicon M340 Processor
During controller maintenance, the memory card can be involved in application restoration or transfer procedures. The actual behavior depends on the processor, application configuration, and supported M340 memory functions, so the card should be treated as part of the complete controller memory architecture rather than as a standalone storage device.
Role in a Modicon M340 PLC Memory Architecture
The BMXRMS008MP occupies the storage layer of a Modicon M340 control system. It supports the processor by retaining supported application or system information while the CPU remains responsible for program execution and machine control.

Installation and Maintenance
- Confirm that the BMXRMS008MP is compatible with the intended Modicon M340 processor and application.
- Back up the existing PLC application before performing memory-card maintenance.
- Power down the relevant equipment when the installation procedure requires the memory card to be removed or inserted.
- Inspect the card and connector area for physical damage or contamination.
- Insert the memory card in the correct orientation and ensure that it is properly seated.
- Avoid removing the card during an active write operation or when system status indicates that removal could affect stored data.
- Verify that the required application and system information is present after installation.
- Check processor diagnostics if the M340 system does not recognize the memory card correctly.
- Confirm that the application configuration corresponds to the intended processor and system architecture.
- Keep a controlled backup of important PLC applications rather than relying on a single memory card.
- Protect the card from electrostatic discharge and mechanical damage during handling.
- After replacement or restoration, verify PLC execution, I/O operation, communication functions, and the machine sequence before returning the system to service.

Technical FAQs
What information can the BMXRMS008MP store?
The memory card is used for supported Modicon M340 application and system information. The exact data handled depends on the processor and application configuration.
Why is a removable memory card useful when replacing an M340 processor?
It can simplify application recovery or transfer when the existing controller is serviced or replaced, provided the stored application and memory-card configuration are compatible with the replacement processor.
What should be considered before removing the BMXRMS008MP?
The controller’s operating state and any active memory operation should be checked first. Application data should also be backed up separately so that controller maintenance does not depend on a single storage medium.
Can the BMXRMS008MP execute a PLC program by itself?
No. The memory card is a storage component and does not execute PLC control logic. The Modicon M340 processor performs program execution and coordinates the connected I/O and communication functions.
