Product Overview – Schneider 140NOE77101
The Schneider 140NOE77101 is an industrial-grade Ethernet communication module designed specifically for the Modicon Quantum series of PLCs (Programmable Logic Controllers). It functions as a TCP/IP network interface module, allowing Quantum PLCs to communicate seamlessly over Ethernet networks with other devices and systems, such as SCADA (Supervisory Control and Data Acquisition) platforms, HMIs (Human-Machine Interfaces), or enterprise-level management systems.
It is equipped with two types of ports: an RJ45 copper Ethernet port (10BASE-T / 100BASE-TX) and a fiber optic MT-RJ port (100BASE-FX), offering flexibility for network topologies. The module supports high-speed data transmission and multiple industrial Ethernet protocols, making it highly suitable for applications that demand real-time data handling and secure communication.
Key Features
1. Multi-Protocol Support
The module supports a wide range of communication protocols including:
-
Modbus TCP/IP – widely used for industrial automation
-
SNMP – used for network management and diagnostics
-
HTTP access – embedded web server for monitoring and diagnostics
-
FTP server – allows file transfers such as logs or firmware
-
Global Data and I/O Scanning services
2. Dual Interface Capability
Equipped with both copper and fiber optic Ethernet interfaces, this module can be easily adapted to different plant environments. Fiber provides long-distance and noise-resistant communication, while copper is suited for shorter, cost-effective connections.
3. Web Server Functionality
An embedded web server enables remote monitoring and diagnostics of the module and the entire Quantum rack. Web pages provide details such as module status, rack configuration, and fault conditions, which simplifies maintenance and troubleshooting.
4. Hot Standby Redundancy Support
It supports Hot Standby configurations for critical applications. In case of primary PLC failure, the secondary controller takes over operations without interruption, improving system reliability.
5. Security and Fault Management
The module provides password protection, bandwidth control, and diagnostic functions such as CRC error counters and packet loss detection. SNMP traps and syslog functions also help in early fault detection.
6. Transparent Ready Integration
As part of Schneider’s Transparent Ready concept, it integrates smoothly into Ethernet architectures and supports direct access from standard browsers, enhancing compatibility and reducing the need for middleware.
7. Environmental Robustness
-
Operating temperature range: 0 to 60°C
-
Relative humidity: Up to 95% (non-condensing)
-
Altitude: Up to 4500 meters
-
Shock and vibration resistance suitable for industrial use
8. Easy Installation
As a rack-mounted module, it plugs directly into a Modicon Quantum backplane, drawing power from the rack and minimizing wiring. It is easily configured using Schneider's Unity Pro or Concept programming environments.
