The 140NOE77101 is a high-performance Ethernet communication module for the Schneider Modicon Quantum platform. Supporting Modbus TCP protocol, I/O Scanning, and Hot Standby redundancy, it features dual interfaces (RJ45 and Fiber Optic) to ensure transparent data transmission and high reliability in demanding industrial environments. Although discontinued in 2018, its built-in Web Server continues to make it a valuable component for remote diagnostics and maintenance in existing systems.
Dual Copper and Fiber Interfaces
Embedded Web Diagnostics
Simplified I/O Scanning Programming
The 140NOE77101 serves as the communication backbone of the Modicon Quantum platform. As a high-performance co-processor, it integrates seamlessly with the PLC via the backplane, handling complex TCP/IP protocols without taxing the main CPU. It plays "multiple roles" within the system: acting as a gateway to SCADA/HMI at the supervisory level, managing distributed devices through I/O Scanning at the field level, and ensuring communication continuity in redundant architectures. With its dual copper/fiber interfaces and embedded Web diagnostics, it establishes a transparent data bridge between field devices and the management layer.

Water & Wastewater
Controls pump station operations and aggregates data from distributed treatment basins to a central control room via Ethernet.
Chemical Industry
Connects remote I/O via fiber interfaces in hazardous areas to ensure precise control of reactor temperature and pressure.
Metallurgy & Mining
Monitors sensor data in blast furnace ironmaking and implements logical interlocking for conveyor systems.
Automotive Manufacturing
Connects numerous PLCs on welding or painting lines to achieve high-speed communication synchronization at the shop-floor level.
Semiconductor Manufacturing
Monitors the status of ultra-pure water and chemical supply systems in cleanroom environments.
When using the 140NOE77101, the primary task is to ensure firmware compatibility with configuration software and the CPU to avoid communication conflicts. At the physical level, choose the optimal connection between RJ45 and Fiber interfaces based on EMI intensity, while strictly adhering to fiber bending radii and connector cleanliness. For configuration, set I/O Scanning rates reasonably to prevent overloading and enable FDR (Fast Device Replacement) for critical missions. Lastly, since the product is discontinued, it is essential to maintain spare parts inventory and develop a system migration plan toward the M580 series.
It is an Ethernet TCP/IP communication module within the Modicon Quantum automation platform by Schneider Electric. It is primarily used to provide industrial Ethernet connectivity for Quantum PLCs, enabling data exchange with PCs or other controllers.
How is the 140NOE77101 installed and powered?
The module follows the standard module format and is plugged directly into a Modicon Quantum rack slot. It is powered via the rack backplane, with a current consumption of approximately 750 mA at 5V DC.
What is the main use of 140NOE77101?
It is mainly used for data exchange between PLCs and supervisory systems (SCADA/HMI), or for establishing communication links between different PLCs for distributed control.
What communication protocols does 140NOE77101 use?
It primarily uses the Modbus TCP protocol, one of the most widely used industrial Ethernet standards, and also supports standard TCP/IP services.
What is the I/O Scanning feature of 140NOE77101?
I/O Scanning is a core feature that allows the PLC to automatically and periodically read or write register data from other remote devices on the network without complex programming.
