Product Details

140NOE77110 Product Description

The Schneider Electric 140NOE77110 is a dedicated Ethernet TCP/IP communication module engineered for the Modicon Quantum PLC platform, one of the most widely deployed high-availability control architectures in heavy industrial environments. Rather than functioning as a standalone network adapter, the 140NOE77110 operates as a deeply integrated node within the Quantum system architecture, enabling deterministic, high-throughput data exchange between the control layer and supervisory or peer-level systems across plant-wide Ethernet infrastructure.

At the control layer, the 140NOE77110 interfaces directly with Quantum CPU modules such as the 140CPU65160 and 140CPU67160, sharing the Quantum backplane bus through a 140XBP series backplane. This tight coupling ensures that network communication latency does not introduce scan-cycle jitter, preserving the real-time determinism that process-critical applications demand. When deployed alongside a redundant CPU pair — for example, in a Hot Standby configuration using the 140CPU67160 with the 140CHS11000 Hot Standby cable — the 140NOE77110 maintains continuous Ethernet connectivity during CPU switchover events, ensuring that SCADA polling and Modbus TCP client connections experience no data loss.

At the I/O layer, the module supports I/O Scanning, a native Quantum feature that allows the 140NOE77110 to autonomously poll remote Ethernet-connected I/O adapters — such as the Advantys STB or Momentum 170ENT11001 Ethernet adapter — without burdening the CPU with explicit communication ladder logic. This distributed I/O scanning capability is particularly valuable in large-footprint installations where field I/O is distributed across multiple cabinets or remote marshalling panels, enabling the control engineer to extend the I/O architecture without adding backplane slots or increasing CPU scan load.

At the communication layer, the 140NOE77110 supports simultaneous Modbus TCP server and client roles, Global Data peer-to-peer messaging, FTP file transfer for recipe and data logging, and HTTP-based diagnostics. This multi-protocol capability allows the module to serve as the primary integration point between the Quantum PLC and third-party systems — including historian servers, MES platforms, and energy management systems — without requiring a dedicated communication gateway. In architectures where protocol translation is required, the module can operate alongside a Moxa MGate or similar Modbus TCP-to-serial gateway to bridge legacy serial field devices into the Ethernet backbone.

At the power layer, the 140NOE77110 draws its operating power entirely from the Quantum backplane, supplied by a 140CPS series power supply module. This eliminates the need for an external 24 VDC supply to the network module, simplifying cabinet wiring and reducing the number of power distribution terminals required. In redundant power configurations, dual 140CPS11420 or 140CPS21400 power supply modules can be installed in the same backplane to provide N+1 power redundancy, ensuring that a single power supply failure does not interrupt network communication.

At the HMI layer, the 140NOE77110 provides the Ethernet backbone connectivity required for Schneider Electric Magelis HMI panels — such as the HMIGTO series — to communicate with the Quantum PLC via Modbus TCP. This direct HMI-to-PLC Ethernet path eliminates the serial RS-232/RS-485 bottleneck common in legacy installations, enabling faster screen refresh rates, larger data block transfers, and simultaneous multi-panel access to the same PLC data table. The module's HTTP server also provides a built-in web diagnostic page accessible from any standard browser, reducing the need for dedicated HMI screens for network health monitoring.

At the maintenance and diagnostics layer, the 140NOE77110 supports SNMP v1 for integration with plant-wide network management systems, enabling IT and OT teams to monitor module health, port status, and traffic statistics from a centralized NMS console. Combined with the Quantum CPU's built-in diagnostic coils and the Unity Pro / EcoStruxure Control Expert programming environment, maintenance engineers can implement structured fault detection routines that correlate network communication errors with process alarms, significantly reducing mean time to repair (MTTR) in the event of a network fault.

The 140NOE77110 is deployed across a broad spectrum of industrial sectors where Modicon Quantum PLCs form the backbone of the control architecture. In power generation and transmission facilities, the module provides the Ethernet TCP/IP interface required for IEC 61850-adjacent SCADA integration, connecting Quantum controllers managing turbine governor systems, transformer protection relays, and switchgear control panels to plant-level DCS and energy management platforms. Its support for simultaneous Modbus TCP client and server roles allows it to aggregate data from multiple field controllers and forward consolidated datasets to the control room historian without requiring an intermediate data concentrator.

In oil and gas upstream and midstream applications, the 140NOE77110 is commonly deployed in wellhead control panels, pipeline SCADA RTU cabinets, and compressor station automation systems. The module's wide operating temperature range and compliance with hazardous-area cabinet installation standards make it suitable for deployment in climate-controlled enclosures within Zone 2 classified areas. Its FTP file transfer capability is leveraged for automated recipe downloads and event log uploads in batch processing applications, reducing the need for manual USB-based data transfer in remote field locations.

In water and wastewater treatment plants, the 140NOE77110 enables Quantum PLCs managing pump stations, filtration systems, and chemical dosing skids to communicate with SCADA servers over plant Ethernet rings. The module's I/O Scanning feature is particularly valuable in these distributed architectures, where remote pump station I/O — connected via Momentum Ethernet adapters — must be polled reliably across multi-hop Ethernet paths. In municipal water networks with geographically dispersed pump stations, the module's robust Modbus TCP client capability allows a central Quantum controller to aggregate flow, pressure, and level data from dozens of remote RTUs over a single Ethernet WAN connection.

In automotive and discrete manufacturing environments, the 140NOE77110 provides the network backbone for Quantum-based machine controllers managing transfer lines, robotic welding cells, and assembly conveyor systems. Its integration with Schneider Electric's EcoStruxure Plant architecture enables seamless data flow from the machine control layer to MES and ERP systems, supporting real-time OEE monitoring, predictive maintenance scheduling, and production order tracking without requiring custom middleware development.

Q1: Can the 140NOE77110 be used in a Quantum Hot Standby redundancy architecture, and does it maintain Ethernet connectivity during a CPU switchover? Yes. The 140NOE77110 is fully compatible with the Modicon Quantum Hot Standby architecture. When installed in a redundant Quantum chassis pair, the module maintains its Ethernet TCP/IP connections and Modbus TCP server sessions during a CPU switchover event. The Hot Standby transfer is transparent to connected SCADA clients and Modbus TCP polling masters, provided the switchover time is within the configured Modbus TCP timeout window. It is recommended to configure Modbus TCP client timeout values of at least 1.5 seconds to accommodate the typical Hot Standby switchover time of 300–500 ms. All units supplied by NANKMOS are pre-shipment tested for Hot Standby compatibility and covered under a 12-Month Warranty.

Q2: What backplane and power supply modules are required to install the 140NOE77110 in a new Quantum rack, and are there slot position restrictions? The 140NOE77110 requires a Modicon Quantum 140XBP series backplane (e.g., 140XBP01600 for a 16-slot rack or 140XBP00600 for a 6-slot rack) and a compatible 140CPS series power supply module. The module can be installed in any I/O slot on the Quantum backplane; there are no fixed slot position restrictions, though Schneider Electric recommends placing communication modules in slots adjacent to the CPU for optimal backplane bus performance. A single Quantum rack can accommodate multiple 140NOE77110 modules for multi-network or redundant network configurations. NANKMOS maintains verified stock of 140XBP and 140CPS series components to support complete rack assembly and Contextual Integration requirements.

Q3: How does NANKMOS ensure the long-term reliability of the 140NOE77110, and what does the 12-Month Warranty cover? Every 140NOE77110 unit supplied by NANKMOS undergoes a structured pre-shipment verification process that includes power-on functional testing, Ethernet port continuity verification, firmware version confirmation, and visual inspection for component integrity. The 12-Month Warranty covers manufacturing defects, functional failures under normal operating conditions, and firmware-related issues identified during the warranty period. NANKMOS maintains a dedicated inventory of Modicon Quantum communication modules to support rapid replacement under warranty claims, minimizing control system downtime. For long-term maintenance planning, NANKMOS can provide multi-unit supply agreements to ensure consistent availability of 140NOE77110 modules for ongoing plant maintenance and expansion projects.
