Modicon X80 Backplane Bus and Ethernet Architecture

The BMEXBP0800 provides eight positions for compatible Modicon X80 modules and carries both X-bus and Ethernet connections across the rack. The mixed backplane architecture permits processors, I/O modules, power supplies, and specific application modules to be installed within the supported configuration.

The XBE connector provides electrical expansion to an additional backplane arrangement where supported by the system architecture. Module placement and bus continuity should follow the applicable Modicon X80 hardware configuration rules.

Frequently Asked Questions

Q: What electrical loads does the BMEXBP0800 impose on the backplane?

A: The specified current consumption is 164 mA at 24 VDC and 64 mA at 3.3 VDC. The corresponding listed power consumption is 3.9 W at 24 VDC and 211 mW at 3.3 VDC.

Q: How many module positions are provided?

A: The rack provides 8 slots with X-bus and Ethernet connectivity for compatible Modicon X80 modules.

Q: Can the BMEXBP0800 be installed on a DIN rail?

A: Yes. The supplied data specifies clip mounting on a 35 mm symmetrical DIN rail. Panel and plate mounting are also specified using the stated screw arrangements.

Field Installation Guidelines

Install the rack on a mechanically rigid panel, plate, or 35 mm symmetrical DIN rail using the specified mounting method. Maintain correct alignment of the backplane connectors before inserting modules.

Verify that the selected processor, power supply, I/O modules, and application modules are compatible with the BMEXBP0800 configuration. Confirm the available 24 VDC and 3.3 VDC backplane current capacity against the complete rack load.

Route power and signal wiring to minimize unnecessary coupling with high-current or high-frequency conductors. Follow the applicable Schneider Electric grounding and EMC requirements for the complete Modicon X80 installation.

The BMEXBP0800 is rated IP20 and should therefore be installed inside an enclosure providing the required protection against environmental contaminants and accidental contact.
