SCHNEIDER ELECTRIC BMXXBP0800 | Modicon X80 8-Slot Backplane

Description

The SCHNEIDER ELECTRIC BMXXBP0800 is an 8-slot X-bus backplane for the Modicon X80 automation platform. It provides the mechanical mounting structure, X-bus electrical connections, grounding, and power distribution interface for compatible PLC processors, I/O modules, communication modules, and application-specific modules.

The BMXXBP0800 can be used with Modicon M340, M580, and X80 module architectures where an X-bus-only rack is appropriate. Schneider Electric specifies panel, mounting-plate, and 35 mm DIN-rail mounting options.

🛠️ Operating Procedure & How to Use

1. Confirm the Rack Type

Before installation, make sure the application requires an X-bus-only backplane.

The BMXXBP0800 does not provide the additional Ethernet backplane found on the BMEXBP0800. Schneider’s documentation distinguishes BMXXBP racks from dual Ethernet/X-bus BMEXBP racks.

2. Plan the Module Arrangement

Determine the position of:

• Power supply
• CPU/processor
• I/O modules
• Communication modules
• Application-specific modules

The power supply occupies its dedicated rack position and the remaining positions accommodate compatible X80 modules.

3. Mount the Backplane

Install the BMXXBP0800 horizontally or according to the approved cabinet design.

For panel installation, use the specified mounting holes. For DIN-rail installation, ensure the clips are fully engaged.

4. Install Modules

Insert each module into its assigned slot and make sure the module connector fully engages with the corresponding backplane connector.

5. Install the Power Supply

Install the compatible BMXCPS power supply in its designated position.

6. Connect the Expansion Bus

If the application uses multiple racks, connect the appropriate XBE expansion arrangement according to the system architecture.

7. Check Grounding

Connect the rack grounding point to the cabinet protective-earth system.

8. Commission the Rack

After all modules are installed, power the system and verify CPU, I/O, and communication diagnostics.

 

⚡ Power-On Sequence

1. 🔒 Place the machine in a safe state.
2. 🔍 Verify the BMXXBP0800 mounting.
3. 🔍 Check grounding and cabinet PE connections.
4. 🔍 Confirm every module is correctly seated.
5. 🔍 Verify the correct BMXCPS power supply.
6. 🔍 Check XBE expansion wiring if used.
7. ⚡ Apply the control-system power.
8. 🟢 Check the power-supply status.
9. 🖥️ Check the CPU/processor diagnostic LEDs.
10. 🔌 Verify I/O module status.
11. 🌐 Check communication modules if installed.
12. ✅ Confirm PLC operation before enabling the controlled machine.

 

🔌 Power-Off Sequence

1. 🛑 Stop the controlled process using the normal machine procedure.
2. 🔒 Put the PLC system into a safe maintenance state.
3. 📴 Stop the CPU/application if required by the control procedure.
4. ⚡ Remove the cabinet/control power.
5. 🔍 Verify that the rack is de-energized.
6. ⏳ Allow the power supply to discharge as specified by the system procedure.
7. 🔧 Remove modules only after electrical isolation is confirmed.
8. 🛡️ Use ESD protection when handling X80 electronics.

⚠️ Do not remove or insert modules while energized unless the specific module and system configuration explicitly support the operation. Schneider notes hot-swapping capability for most I/O modules, but this should not be interpreted as permission to hot-swap every module or the rack itself.

 

📖 Product Usage Instructions

The BMXXBP0800 acts as the physical and electrical backbone of an X80 PLC rack.

A typical arrangement is:

BMXCPS Power Supply → BMXXBP0800 → CPU / I/O / Communication Modules

The backplane provides the internal X-bus connections required for communication between installed modules. Schneider documentation describes the rack as providing the communication bus and power interface for modules installed on the rack.

For an application requiring Ethernet communication directly through the rack backplane, the BMEXBP0800 or another appropriate dual Ethernet/X-bus rack may be required instead. The BMXXBP0800 itself is an X-bus rack without an Ethernet backplane.

 

🔍 Installation & Commissioning Checklist

Before startup:

• Confirm BMXXBP0800 part number.

• Verify eight available X-bus module positions.

• Check mounting screws or DIN-rail clips.

• Verify protective-earth connection.

• Check backplane connectors for damage.

• Install the correct power supply.

• Verify CPU compatibility.

• Check I/O module compatibility.

• Verify XBE expansion wiring where applicable.

• Confirm module slot arrangement.

• Check all locking screws.

• Power up and check diagnostic LEDs.

• Verify PLC communication.

 

❓ Common Questions & Answers

Q: What is Schneider BMXXBP0800?

A: It is an 8-slot X-bus backplane for the Modicon X80 automation platform.

A: Yes. Schneider specifies mounting by clips on a 35 mm symmetrical DIN rail, as well as screw mounting on a panel or mounting plate.

Q: Does BMXXBP0800 include a power supply?

A: No. It is the backplane/rack. A compatible BMXCPS power supply must be installed separately.

Q: What is the XBE connector used for?

A: The XBE connector is used for connection to an expansion module/rack expansion arrangement.

Q: What is the difference between BMXXBP0800 and BMEXBP0800?

A: BMXXBP0800 is an X-bus-only 8-slot rack, while BMEXBP0800 is an 8-slot dual Ethernet and X-bus rack.
