The Schneider Electric 140NOE21110 module serves as a dedicated Ethernet communication interface for Modicon automation platforms. This unit enables reliable data exchange between programmable logic controllers and higher-level network systems.
Specifically, the 140NOE21110 integrates a single Ethernet port that supports both 10 Mbps and 100 Mbps speeds. Additionally, it includes an RS232 serial port for legacy device connections. The module communicates via the widely adopted Modbus protocol, ensuring seamless interoperability with numerous field devices and supervisory systems.
Moreover, this communication module operates on a 5V DC supply with a low power draw of just 3.5 watts. Its lightweight construction and small footprint make it an excellent choice for space-constrained control cabinets. Consequently, system integrators often select the 140NOE21110 for upgrading older networks or adding Ethernet capability to existing Modicon installations.
Ethernet Connectivity
One RJ45 port supports auto-negotiation at 10/100 Mbps.
The interface handles full-duplex and half-duplex modes.
Auto-crossover (MDI/MDIX) simplifies cabling without requiring special cross-over cables.
Serial Interface
One RS232 port (DB9 connector) supports point-to-point serial communication.
This port works well for programming, diagnostics, or connecting to older serial instruments.
Protocol Support
Native Modbus TCP/IP over Ethernet.
Modbus RTU over the serial RS232 link.
This dual-protocol capability gives you flexibility in mixed network environments.
Electrical Ratings
Rated voltage: 5V DC (nominal).
Output power consumption: 3.5W maximum.
The module draws its power directly from the backplane, eliminating the need for an external supply.
Physical Dimensions
Height: 100 mm
Width: 40 mm
Depth: 130 mm
These compact dimensions allow the 140NOE21110 to fit easily into standard Modicon racks alongside other I/O and control modules.
Weight
Unit weight: 0.3 kg
Shipping weight (with packaging): approximately 0.65 kg
Temperature Ranges
Operating temperature: 0°C to 60°C – suitable for most factory floor environments.
Storage temperature: -40°C to 85°C – protects the module during transport or warehouse storage.
Humidity and Altitude
Humidity tolerance: 5% to 95% (non-condensing), ensuring reliable operation in humid climates.
Maximum operating altitude: 1000 meters above sea level – ideal for facilities located at higher elevations.
First, ensure that the host Modicon rack is powered off before inserting the 140NOE21110 module. Next, align the module with the guide rails in the chassis and slide it firmly into the designated slot. Secure the unit by tightening the top and bottom retaining screws.
After physical installation, connect the Ethernet cable to the RJ45 port for network access. If you need serial communication, attach your RS232 device to the DB9 connector. For proper operation, verify that the backplane provides stable 5V DC power within the specified tolerance.
Furthermore, always observe electrostatic discharge (ESD) precautions during handling. Ground yourself before touching the module’s circuit components. For network configuration, use the module’s built-in web interface or Schneider Electric’s programming software to set IP addresses and communication parameters.

Q1: Is the 140NOE21110 compatible with older Modicon Quantum systems?
Yes, the 140NOE21110 is specifically designed for Modicon Quantum and Premium platforms. It fits standard rack slots and works seamlessly with the backplane communication bus.
Q2: Can I use both Ethernet and RS232 ports simultaneously?
Absolutely. The 140NOE21110 supports concurrent operation of its Ethernet and RS232 interfaces. For instance, you can use Ethernet for supervisory control while the serial port handles local programming or peripheral connections.
Q3: What type of Ethernet cable should I use with this module?
Use a standard Category 5e (Cat5e) or higher shielded or unshielded twisted-pair cable. The auto-MDI/MDIX feature allows you to use either straight-through or cross-over cables without any issue.
Q4: Does this module support DHCP for automatic IP assignment?
Yes, the 140NOE21110 supports both static IP configuration and DHCP. You can choose either method during initial setup via the configuration software or web interface.
Q5: What should I do if the module does not power up after installation?
First, verify that the backplane supplies stable 5V DC power. Next, check that the module is securely seated and the retaining screws are tight. If the issue persists, test the module in a different slot to rule out rack-related problems.
