Installation Guide

1. Mount the BMXXBP0800 on a 35 mm symmetrical DIN rail or panel using 4 screws (M4/M5/M6, hole diameter 4.32–6.35 mm).
2. Ensure minimum clearance: ≥60 mm from cabinet sides, ≥80 mm from wiring duct or tray.
3. Install the BMXCPS power supply module in the leftmost dedicated power supply slot.
4. Install the BMXP34 processor module in the adjacent CPU slot.
5. Install I/O modules and special application modules in the remaining slots.
6. For multi-rack systems, connect BMXXBE1000 backplane expander to the XBE connector on the rightmost side of the rack.
7. Verify all modules are fully seated and secured with captive screws.
8. Power on and verify module status via Unity Pro or EcoStruxure Control Expert diagnostics.

FAQ

Q: Is BMXXBP0800 a digital output module?
A: No. Some third-party sources incorrectly describe it as an 8-channel 24VDC transistor output module. The BMXXBP0800 is an 8-slot X-bus backplane — it provides mechanical mounting and electrical bus connections for X80 modules, not I/O signal processing.

Q: What is the difference between BMXXBP0800 and BMXXBP0800H?
A: BMXXBP0800 is the standard version (0°C to +60°C). BMXXBP0800H is the ruggedized version with extended temperature range (-25°C to +70°C) and enhanced environmental resistance.

Q: Is BMXXBP0800 compatible with M580?
A: Yes. The BMXXBP0800 is the same backplane used by both Modicon M340 and Modicon M580 systems. This enables seamless upgrades from M340 to M580 without changing the rack infrastructure.

Q: How many racks can I connect with BMXXBP0800?
A: Up to 4 racks total using BMXXBE1000 backplane expanders connected via the XBE connector on each rack.

Q: Does the power supply occupy an I/O slot?
A: No. The BMXXBP0800 has a dedicated power supply slot that does not consume any of the 8 standard I/O slots, maximizing rack utilization.

Q: What is the maximum number of I/O modules?
A: The backplane has 8 slots. After accounting for the power supply and CPU, up to 6 I/O or application modules can be installed (depending on module width — some modules occupy 2 slots).
