Schneider Electric BMXXBP0800 Modicon M340 8-Slot Rack

The Schneider Electric BMXXBP0800, also cataloged as the BMXXBP0800 rack chassis, serves as the primary BMXXBP0800 PLC rack utilized to execute modular backplane power distribution and high-speed bus communication across Modicon M340 platforms.

Suffix Breakdown & Model Matrix

The part number follows standard Schneider Electric Modicon M340 naming conventions:

• BMX: Designates the Modicon M340 product family platform.
• XBP: Identifies backplane rack chassis hardware.
• 0800: Specifies an 8-slot non-extended backplane configuration.

Hardware Specifications

Profinet / EtherNet/IP Deterministic Networks and I/O Density

The BMXXBP0800 backplane chassis integrates the high-speed Ethernet and X-bus communication backplane, allowing real-time data transfers between the power supply, CPU, and expanded I/O modules. The physical internal architecture provides channel-to-channel signal integrity and deterministic update times for digital and analog processing. Its high I/O density scaling allows 8 modules to be mounted in a compact footprint without compromising electrical isolation or backplane data throughput.

Frequently Asked Questions

Q: Does the BMXXBP0800 require external bus termination resistors when used as a standalone rack?

A: No. Standard BMXXBP0800 racks operate as single non-extended backplanes and do not require external bus expansion terminators unless extended via expansion rack modules.

Q: Can modules be hot-swapped while the BMXXBP0800 backplane is powered?

A: Hot-swapping (RIOH) support depends on the specific CPU and module type installed; however, power supply units must always be powered down before extraction from the backplane.

Field Installation Guidelines

• Mount the rack horizontally on a standard 35 mm DIN rail or directly to an enclosure mounting plate using M4 screws.
• Connect the protective earth (PE) ground wire to the dedicated grounding terminal screw on the side of the chassis frame to ensure proper surge protection and noise immunity.
• Ensure minimum vertical clearances of 80 mm above and below the rack assembly to facilitate unobstructed natural convection cooling.
