Product Overview
In modern industrial automation systems, reliable Ethernet communication is essential for connecting PLC controllers with supervisory systems, engineering workstations, HMIs, industrial networks, and other automation equipment. The Schneider 140NOE77101C Ethernet TCP/IP Module is a communication module designed for the Modicon Quantum PLC platform, providing Ethernet-based networking capabilities within the control architecture.
The 140NOE77101C is part of the Quantum communication-module family and is designed to provide an Ethernet interface for exchanging data between the PLC system and connected network devices.
By supporting TCP/IP-based communication, the module can connect the Quantum controller to higher-level automation networks and facilitate communication between PLC systems and industrial Ethernet devices.
The module is therefore different from a conventional digital I/O module. Rather than directly controlling field devices, it provides a communication pathway that allows control information, diagnostics, status data, and other information to be exchanged across an Ethernet network.
The specified dimensions of the 140NOE77101C are 103.9 × 40.3 × 250 mm, with a specified weight of 0.345 kg.

Function and Working Principle
The primary function of the 140NOE77101C is to provide Ethernet communication between the Modicon Quantum PLC system and external network devices.
A simplified communication path can be represented as:
Quantum PLC → 140NOE77101C → Ethernet Network → HMI / SCADA / PLC / Engineering System
The module receives communication information from the Quantum control system and transfers the relevant data through the Ethernet network.
Conversely, information received from connected Ethernet devices can be transferred into the PLC system for processing by the control application.
This makes the module useful for exchanging:
- PLC status information
- Process data
- Diagnostic information
- Control commands
- Device information
- Production data
- Supervisory-system information
- Network communication data
The Ethernet interface allows the Quantum PLC to participate in a larger automation network rather than operating as an isolated controller.
The actual communication architecture depends on the PLC program, network topology, addressing configuration, and connected devices.
Role in Industrial Control Systems
The Schneider 140NOE77101C provides an important communication layer within a Modicon Quantum PLC system.
A typical industrial control system can contain PLC processors, local I/O, remote I/O, HMIs, SCADA servers, engineering stations, drives, intelligent devices, and other controllers.
The Ethernet TCP/IP module provides the communication path required to connect the Quantum system to this wider automation environment.
It can work alongside:
- Modicon Quantum CPUs
- Quantum power supplies
- Quantum racks and backplanes
- Digital I/O modules
- Analog I/O modules
- HMI systems
- SCADA systems
- Engineering workstations
- Industrial Ethernet switches
- Other PLC controllers
- Ethernet-capable automation devices
This architecture allows process information to move between the control level and supervisory or networked systems.
Industrial Applications
The Schneider 140NOE77101C is suitable for industrial applications where Ethernet communication is required within a Quantum PLC architecture.
Typical applications include:
- Factory automation
- Process control
- Manufacturing systems
- Water and wastewater plants
- Material-handling systems
- Packaging machinery
- Production lines
- Energy-management systems
- Building automation
- Industrial monitoring
- SCADA communication
- PLC-to-PLC networking
For example, a Quantum PLC can use the Ethernet communication module to exchange process information with an HMI or SCADA system.
In a larger plant, the module can also form part of an Ethernet infrastructure connecting several controllers and supervisory systems.
Installation and System Integration
Correct installation and network configuration are important for reliable operation of the 140NOE77101C.
Before installation, technicians should verify the Quantum rack configuration, module position, network design, and IP-addressing requirements.
Recommended procedures include:
- Shut down the relevant PLC system according to the approved procedure.
- Isolate power where required.
- Verify the complete 140NOE77101C model.
- Confirm the intended Quantum rack position.
- Inspect the module for physical damage.
- Verify the rack and backplane condition.
- Install the module in the designated position.
- Secure the module correctly.
- Connect the Ethernet network cable.
- Verify network topology and cable routing.
- Configure the required network parameters.
- Verify IP addressing and communication settings.
- Restore PLC power.
- Check module status indicators.
- Verify Ethernet link status.
- Test communication with the connected network device.
- Check PLC diagnostics.
- Verify application-level data exchange.
- Perform system-level communication testing.
Network configuration should be consistent with the existing industrial Ethernet architecture.
Incorrect addressing, duplicated IP addresses, incompatible network configuration, or defective cabling can cause communication failures even when the module itself is functioning correctly.
