Product Overview

The Schneider Electric BMECXM0100 is a CANopen communication module for the Modicon X80 platform.
This module serves as an open industrial fieldbus interface for automation systems.
It is fully compatible with M580 PLCs from Schneider Electric.
The BMECXM0100 uses a DB9 connector for physical network connection.
CSMA/CA access method ensures reliable data transmission on the bus.
NRZ transmission mode provides efficient bit encoding for higher speeds.
Consequently, this module integrates CANopen devices seamlessly into Modicon control systems.

Technical Specifications

Communication Features

The BMECXM0100 supports up to 63 CANopen server devices on a single network.
Communication services follow CiA DSP 301 V4.02 for full standard compliance.
Transmission support medium uses CANopen twisted shielded pairs cable .
This cable type ensures noise immunity in industrial environments.
The module's structure type is an open industrial fieldbus for maximum flexibility.

Transmission Rates and Bus Lengths

At 1 Mbit/s , the maximum bus length reaches 20 meters without a repeater.
For 500 kbit/s , bus length extends to 100 meters without a repeater.
At 250 kbit/s , maximum bus length reaches 250 meters with a repeater.
For 125 kbit/s , bus length extends to 500 meters with a repeater.
At 50 kbit/s , maximum bus length reaches 1000 meters with a repeater.
For 20 kbit/s , bus length extends to 2500 meters with a repeater.
Thus, the BMECXM0100 adapts to various network size requirements.

Power and Physical Data

Rated supply voltage is 24 V DC from the internal backplane.
Current consumption equals 100 mA for low power operation.
The module uses a standard format for Modicon X80 racks.
Physical interface uses a DB9 connector for CANopen cabling.

Compatibility

The Schneider Electric BMECXM0100 is specifically designed for M580 PLCs.
It also fits into any Modicon X80 rack with standard slots.
Mixed configurations with other X80 I/O modules are fully supported.
Therefore, system expansion remains flexible and straightforward.

Environmental Specifications

Ambient air temperature for operation ranges from 0 to 60 °C .
Storage temperature withstands extreme conditions from -45 to 85 °C .
Relative humidity tolerance reaches 10 to 95% without condensation.
Operating altitude is limited to <= 2000 meters for normal use.
The BMECXM0100 complies with multiple European directives.
These include 2014/35/EU (low voltage) and 2014/30/EU (EMC).

Installation Guidelines

First, insert the BMECXM0100 into any standard slot of an X80 rack.
Ensure the rack power supply provides adequate 24 V DC power.
Connect the CANopen bus cable to the DB9 connector on the module.
Use twisted shielded pairs cable specifically rated for CANopen.
Set the correct baud rate in the M580 PLC configuration software.
Match the baud rate to the bus length of your network.
For 1 Mbit/s, keep total cable length under 20 meters .
Install terminating resistors (120 ohm) at both physical bus ends.
Do not exceed 63 devices on a single CANopen network.
After wiring, verify communication status using PLC diagnostics.

Cabling Guidelines

Use dedicated CANopen cable with characteristic impedance of 120 ohms.
Connect CAN_H and CAN_L signals to the correct DB9 pins (2 and 7).
Connect the shield to the DB9 connector housing for grounding.
For long runs above 100 meters, use repeaters as specified.
Keep CANopen cable separated from high-power AC wiring.
Maintain at least 200 mm distance from variable frequency drives.
Avoid star topologies unless using a CANopen hub or repeater.
Daisy-chain or trunkline-drop line configurations work best.
Label all cables clearly with network segment information.

System Integration

The Schneider Electric BMECXM0100 integrates into Unity Pro or EcoStruxure Control Expert.
Configuration occurs within the M580 PLC project structure.
CANopen devices are added as slaves under the module tree.
PDO mapping and SDO services configure device parameters.
Network management (NMT) controls slave device states automatically.
The module handles all CANopen communication overhead independently.
Thus, the PLC application focuses on control logic, not bus management.

Frequently Asked Questions (FAQ)

1. Can the BMECXM0100 work with M340 PLCs?

No, the Schneider BMECXM0100 is designed for M580 PLCs only. For M340, use the BMXP3420102 processor with integrated CANopen.

2. How many repeaters can I use on one CANopen network?

The number of repeaters depends on signal delay requirements. For the BMECXM0100 , consult the CANopen specification for repeater limits.

3. Does this module support CANopen FD (Flexible Data)?

No, the Schneider Electric BMECXM0100 supports standard CANopen only. CANopen FD requires a different compatible module.

4. What happens if I exceed the 63 device limit?

The BMECXM0100 cannot address more than 63 devices. Use a second module or CANopen gateway for larger networks.

5. Can I use this module in a redundant PLC configuration?

Yes, the BMECXM0100 supports M580 hot standby configurations. Consult the Schneider Electric redundancy manual for specific guidelines.
