Backplane Bus Communication Velocity Licences
The BMEXBP1002 supports deterministic backplane data exchange between BMEP58 and BMEH58 processors and associated I/O modules over Ethernet-enabled Bus X architecture. Licensing constraints apply to high-speed data transactions and firmware compatibility between controller and rack firmware versions. Backplane synchronization is governed by the controller’s execution cycle, with no additional latency introduced by passive rack hardware.
Frequently Asked Questions
Q: Does the BMEXBP1002 support hot-swapping of I/O modules?
A: Hot-swap capability depends strictly on the installed I/O module firmware and system configuration; the rack itself imposes no electrical restriction on insertion or removal under load.
Q: Can redundant power supplies be installed in this rack?
A: Yes. The rack supports redundant power supply operation when fitted with compatible BMXCPS4002 units, ensuring uninterrupted backplane power.
Q: Is the Ethernet backplane electrically isolated per slot?
A: No. Ethernet channels share the rack backplane infrastructure without individual galvanic isolation between slots.
Field Installation Guidelines
Mount the BMEXBP1002 using four M6 screws on a flat surface or four screws (diameter 4.32 to 6.35 mm) on a panel. For DIN rail installation, secure the rack using compatible 35 mm symmetrical DIN rail clips. Ensure all mounting surfaces are clean and free from conductive debris. Route signal cables away from high-power lines to minimize electromagnetic interference. Ground the rack chassis directly to the control cabinet earth bar using a low-impedance conductor. Verify torque specifications during screw fastening to prevent mechanical stress on the backplane connectors.
