Schneider Electric 140NOE77100 – Ethernet TCP/IP Communication Module | Modicon Quantum Platform
Engineering Background
The Modicon Quantum series represents Schneider Electric’s flagship high-availability PLC platform, engineered for mission-critical process control in power generation, oil & gas, water treatment, and heavy manufacturing. The 140NOE77100 is the dedicated Ethernet TCP/IP network option module for this platform, enabling seamless integration of Quantum racks into plant-wide Ethernet/IP and SCADA networks.
Product Positioning
Designed for procurement engineers and system integrators who require a proven, OEM-sourced Ethernet interface for existing Quantum installations or new greenfield deployments. The 140NOE77100 eliminates the need for third-party gateways by providing native TCP/IP connectivity directly on the Quantum backplane, reducing latency, simplifying architecture, and maintaining full compatibility with Unity Pro / Control Expert engineering software.

Proven Application Environments
- Oil & Gas: Upstream wellhead control and downstream refinery DCS integration via Modbus TCP to SCADA hosts
- Power Generation: Turbine and boiler control systems requiring high-availability Ethernet redundancy
- Water & Wastewater: Remote I/O scanning across distributed pump stations and treatment facilities
- Automotive Manufacturing: Production line PLC-to-MES data exchange over plant Ethernet backbone
- Pharmaceutical: FDA 21 CFR Part 11 compliant batch process control with audit-trail data logging via FTP
- Mining & Minerals: Conveyor and crusher control in harsh electrical environments
- Building Automation: Integration of Quantum controllers into BMS networks via SNMP and web server diagnostics
Engineering Advantages
- Native Backplane Integration: Mounts directly in any Quantum local rack slot — no external power supply or gateway hardware required
- Dual-Role Modbus TCP: Operates simultaneously as server (for SCADA polling) and client (for peer-to-peer I/O scanning), reducing scan cycle overhead
- Embedded Web Server: HTTP diagnostics page accessible from any browser for real-time module status, I/O scan table, and network statistics — no additional software needed
- SNMP v1 Agent: Integrates with enterprise network management systems (NMS) for proactive fault detection and trap generation
- FTP File Transfer: Supports automated data logging and configuration backup to network file servers
- Auto-Negotiation: 10/100 Mbps auto-sensing eliminates manual switch configuration errors during commissioning
- Hot-Standby Compatible: Fully supported in Quantum Hot Standby (HSB) redundancy configurations with deterministic failover
- Long Production Lifecycle: Established module with extensive installed base — replacement parts and engineering expertise widely available
System Architecture & Signal Flow
The 140NOE77100 occupies a single slot in the Modicon Quantum local rack and communicates with the CPU (e.g., 140CPU65150) via the high-speed Quantum local bus. Ethernet frames are processed by the module’s onboard processor, decoupling network traffic from the CPU scan cycle. Typical architecture:
- Layer 1–2: RJ-45 → managed industrial Ethernet switch (e.g., ConneXium / Hirschmann) → plant LAN
- Layer 3–7: Modbus TCP polling from SCADA/DCS host (Wonderware, iFIX, Ignition) → 140NOE77100 → Quantum CPU data table
- I/O Scanning: 140NOE77100 acts as Modbus TCP client → polls remote Momentum / STB / Advantys I/O drops → writes to local CPU %MW registers
- Global Data: Multicast UDP distribution of shared data blocks between multiple Quantum stations on the same subnet

Technical FAQ
Q: Is the 140NOE77100 compatible with EcoStruxure Control Expert (formerly Unity Pro)?
A: Yes. The module is fully supported in all versions of Unity Pro and EcoStruxure Control Expert. Configuration is performed via the Network Option Module (NOM) configuration tool integrated in the software.
Q: Can this module be used in a Quantum Hot Standby configuration?
A: Yes. The 140NOE77100 is qualified for use in Quantum HSB systems. Both primary and standby racks require individual modules; the active module handles all Ethernet traffic and the standby module takes over transparently on failover.
Q: What is the maximum number of Modbus TCP connections?
A: The module supports up to 64 simultaneous TCP connections, which can be allocated across server (inbound) and client (I/O scanning) roles.
Q: Does the module support DHCP or does it require a static IP?
A: The 140NOE77100 supports both static IP assignment (recommended for production systems) and BOOTP/DHCP for initial commissioning. Static IP is strongly recommended for operational stability.
Q: What is the difference between 140NOE77100 and 140NOE77101?
A: The 140NOE77101 is a later revision with enhanced firmware features. Both are functionally interchangeable for standard Modbus TCP and I/O scanning applications. Confirm firmware compatibility with your Unity Pro version before substitution.
Q: Can I source a Certificate of Conformance (CoC) or test report?
A: Yes. CoC documentation is available upon request for new OEM units. For refurbished units, a pre-shipment test report is provided.
