System Architecture & Signal Flow
The 140NOE77111 occupies a standard Modicon Quantum backplane slot and communicates with the CPU (e.g., 140CPU65160, 140CPU67160) via the local bus at backplane speed. On the network side, the module acts as both a Modbus TCP server (responding to SCADA/HMI polling) and a Modbus TCP client (initiating peer-to-peer PLC messaging). Data flow:
Field I/O → Quantum Backplane → 140NOE77111 → Ethernet Switch → SCADA / HMI / MES / Peer PLCs
The embedded web server runs concurrently on port 80, providing live register data and module health without consuming Modbus TCP connection slots. SNMP traps are issued asynchronously on link-state changes or module faults.

Technical FAQ
Q: Is the 140NOE77111 compatible with Unity Pro and Control Expert?
A: Yes. The module is fully supported in both Unity Pro (legacy) and EcoStruxure Control Expert (current), including online diagnostics and firmware upgrade functions.
Q: Can this module replace the 140NOE77100 or 140NOE77101?
A: The 140NOE77111 is the current production revision and is backward-compatible with earlier NOE771xx variants in most Quantum configurations. Verify your CPU firmware version and Unity Pro project settings before substitution.
Q: Does it support EtherNet/IP (CIP)?
A: The 140NOE77111 supports EtherNet/IP in read-only (adapter) mode for integration with Rockwell-based systems. Full originator (scanner) functionality requires a dedicated EtherNet/IP module.
Q: What is the maximum cable length for the RJ45 port?
A: Standard 100BaseTX specification applies: maximum 100 m per segment using Cat5e or Cat6 UTP/STP cable.
Q: Is this module suitable for SIL 2 / SIL 3 safety applications?
A: The 140NOE77111 is not a safety-rated (SIL) module. For functional safety applications, refer to Schneider Electric’s Modicon Safety PLC range (e.g., Modicon M580 Safety or Preventa).
Q: Can I order a single unit or is there a minimum order quantity?
A: Konmask.com supplies single units and bulk orders. No minimum order quantity applies for standard stock items.
