Description

Schneider Electric BMXXBE1000 Modicon M340 Automation Platform

Configured for multiracks configuration in Modicon M340 automation platform networks, the Schneider Electric BMXXBE1000 (BMXXBE1000 Backplane expander) provides direct physical/electrical execution. It serves as a dedicated hardware module to extend the backplane bus across multiple racks, ensuring deterministic signal and data transmission.

Backplane Bus Communication Velocity and Deterministic Networks

The BMXXBE1000 is engineered to maintain rigid backplane bus communication velocity across expanded multirack architectures. By facilitating high-speed data transfers through its dual SUB-D 9 female connectors, the module prevents deterministic network latency issues within the Modicon M340 platform. The dedicated internal collision detection circuitry, mapped to the red COL LED, monitors data packet integrity across the physical backplane segments, maintaining deterministic I/O timing constraints and preventing firmware flash compatibility faults during multi-rack operations.

Frequently Asked Questions

Q: What do the local signaling LEDs indicate during a fault?

A: The green RUN LED indicates active bus operating status. The red COL LED illuminates when a rack collision error occurs on the extended bus. The four green LEDs display the specific hardware rack address status for diagnosis.

Q: Can the BMXXBE1000 be used on any Modicon backplane?

A: The module is compatible with specific Modicon M340 backplanes, including the BMXXBP0400, BMXXBP0600, BMXXBP0800, and BMXXBP1200 rack models.

Field Installation Guidelines

• Mounting and Placement: Install the module firmly onto the designated slot of the compatible BMXXBP series backplane. Ensure the operating ambient temperature remains within 0...60 degC.
• Wiring and Connectivity: Use specified shielded cables for the two SUB-D 9 female connectors to mitigate electromagnetic interference. Maintain proper separation between low-voltage bus cables and high-power electrical wiring.
• Grounding: Ensure the backplane rack is bonded to the functional earth ground rail using a low-impedance copper conductor to comply with directive 2014/30/EU.
