Schneider BMXXBP1002 Modicon X80 Backplane Rack

Configured for mechanical module hosting and dual-bus signal distribution in Modicon X80 automation network platforms, the Schneider Electric BMXXBP1002 (BMXXBP1002 Rack Chassis) provides direct physical/electrical execution. The hardware functions as a multi-slot structural backplane that routes both asynchronous serial X-bus signals and high-bandwidth deterministic Ethernet packets between plugged processors, power supplies, and high-density I/O units.

Hardware Specifications

Schneider Electric Deterministic Network Architecture

• Profinet / EtherNet/IP Deterministic Networks Integration: The module integrates a parallel dual-bus architecture across its physical copper tracks. It embeds deterministic Ethernet traces directly into 8 of its slot connectors, enabling BME processors to cycle EtherNet/IP and Profinet frames directly to specialized communication and digital network devices without protocol conversion lag.
• I/O Density Scaling Matrix Protection: The internal layout sets fixed characteristic impedance across all 10 card channels. This design maintains steady square-wave clock edges across maximum I/O density configurations, preventing localized noise injection or signal cross-talk from corrupting register transfers during high-speed CPU scan tasks.

Frequently Asked Questions

Q: What are the restrictions for hot-swapping or replacing elements inside the BMXXBP1002 frame?

A: Standard Modicon X80 peripheral I/O modules can be hot-swapped while the backplane rails are energized. However, the BMX/BME processor module and the primary BMXCPS4002 power supply module must never be unseated or inserted under live conditions; doing so breaks the internal 3.3 V DC and 24 V DC backplane power rails, causing an immediate drop of all active control loops.

Q: How do the two X-bus-only slots function compared to the eight dual-bus slots?

A: The final two slots lack the physical internal traces required to route Ethernet backplane networks. These slots are dedicated exclusively to standard X-bus serial modules, such as discrete input/output cards and classic counter blocks, freeing up the high-speed Ethernet-enabled slots for intensive network or process automation modules.

Field Installation Guidelines

• Chassis Layout Alignment, Clearance Constraints, and Mechanical Seating: Mount the 1.37 kg backplane horizontally onto a flat plate using four M6 structural screws or onto a structural panel using fasteners between 4.32 mm and 6.35 mm in diameter. To ensure unrestricted passive thermal convection air currents, maintain a strict mechanical boundary clearance of 50 mm above, below, and around the rack perimeter.
• Conductor Separation, Wireway Constraints, and Shield Grounding: Route all external field wiring and communication cabling through dedicated plastic trays separated from high-potential AC lines or motor starter wiring. Ensure that the metallic grounding points on the rear of the backplane establish tight metal-on-metal contact with the enclosure backplate, which must link directly to the master copper earth ground bar to discharge ambient electrostatic spikes.
