Installation Guide

1. Mount the BMEXBP1002 on a 35 mm symmetrical DIN rail or panel using 4 screws (4.32–6.35 mm diameter) or 4 × M6 screws for mounting plate.
2. Install two BMXCPS4002● redundant power supplies in the dedicated CPS1 and CPS2 slots (leftmost positions).
3. Install the BMEP58/BMEH58 processor module in slot 0 (must be in the main rack, not expansion).
4. Install I/O modules, communication modules, and application-specific modules in the remaining 8 dual-bus slots or 2 X-bus-only slots.
5. Connect Ethernet cables (Cat 5e/6) to the embedded switch ports for distributed I/O (EIO) and peer-to-peer communication.
6. For multirack systems, connect BMXXBE1000 backplane expander to the XBE connector on the right side.
7. Install BMXXSP●●● shielding connection kit at the attachment points for EMC compliance.
8. Connect grounding screw to panel earth.
9. Power on and verify module status via EcoStruxure Control Expert diagnostics.

FAQ

Q: Is the correct model BMXXBP1002 or BMEXBP1002?
A: BMEXBP1002 is the correct spelling. BMXXBP series are X-bus only backplanes (BMXXBP0400/0600/0800/1200). BMEXBP series are Ethernet + X-bus dual bus backplanes for M580 (BMEXBP0400/0800/1200/0602/1002). The "E" in BMEXBP stands for Ethernet.

Q: Can I use a standard power supply in the dual power supply slots?
A: No. The CPS1 and CPS2 slots are only compatible with BMXCPS4002● redundant power supplies. Standard power supplies (BMXCPS2000/2010/3500/3540) cannot be installed in these dedicated slots. However, a single BMXCPS4002● can be used in a standard backplane.

Q: How many Ethernet ports does each slot have?
A: The 8 dual-bus slots each have 2 Ethernet connectors (for ring or daisy-chain topology) plus the X-bus connector. The 2 X-bus-only slots have no Ethernet connectivity.

Q: Is BMEXBP1002 compatible with M340?
A> Partially. M340 processors (BMXP34) can be installed in BMEXBP backplanes but cannot use the Ethernet connectivity — they only communicate via X-bus. For full Ethernet functionality, use M580 processors (BMEP58/BMEH58).

Q: What is the maximum number of expansion racks?
A: Up to 7 expansion racks with a cumulative distance of 30 meters (98 ft) using BMXXBE1000 expanders and X-bus cables.

Q: What is the difference between BMEXBP1002 and BMEXBP1002H?
A: BMEXBP1002 is the standard version (0°C to +60°C). BMEXBP1002H is the ruggedized version with extended temperature range (-25°C to +70°C) and enhanced environmental resistance.
