Configured for high-speed industrial data exchange in Modicon Quantum platforms, the Schneider Electric 140NOE77101 (140NOE77101 Ethernet Network TCP/IP Module) serves as the primary Transparent Ready hardware component utilized to execute Modbus TCP messaging, I/O scanning, and SNMP network management.

Model Architecture and Configuration

The 140NOE77101 is a standard format module designed for Modicon Quantum racks. It provides dual physical interface support: RJ45 for 10/100BASE-TX twisted pair and MT/RJ for 100BASE-FX fiber optic connections. The module operates as a Class B30 web server, facilitating remote diagnostics and data editing through predefined web pages and Rack Viewer services.

Hardware Specifications

Industrial Control Backplane Communication

The Modicon Quantum platform relies on consistent backplane bus communication velocity to maintain real-time data integrity. The 140NOE77101 enables deterministic I/O scanning and global data exchange, provided the firmware flash compatibility aligns with the host CPU requirements. High-density I/O configurations must be validated against the module’s processing capacity to ensure that scan cycle latencies remain within system tolerances during peak network traffic.

Ordering Info

• 1 x 140NOE77101 Ethernet network module

• Note: Field installation requires appropriate twisted pair or fiber optic cabling, depending on the selected physical interface port.

Field Installation Guidelines

• Mounting: Seat the module into an available slot within the Quantum rack, ensuring the rear connector fully engages with the backplane.

• Cabling: Use shielded RJ45 cabling for 10/100BASE-TX connections; observe fiber optic bend radius constraints when utilizing the MT/RJ port.

• Redundancy: The module supports hot standby redundant architectures; configure primary and secondary modules according to the specific system redundancy manual.

• Grounding: Ensure the rack chassis is bonded to earth ground to meet electrostatic discharge (4 kV contact / 8 kV air) and electromagnetic field immunity standards.

Frequently Asked Questions

• Q: Does this module support hot-swapping?

  A: Yes, the 140NOE77101 is designed to be hot-swapped within a powered Modicon Quantum rack without disrupting the backplane logic, provided the system is configured for redundancy.

• Q: How does the module indicate communication status?

  A: The front panel includes a comprehensive LED array indicating Link, Active, TxAct/RxAct, Full-duplex mode, and network data rate (10/100 Mbps).

• Q: What is the maximum operating altitude?

  A: The module is rated for reliable operation up to an altitude of 4500 m.

• Q: Is this module compatible with Modbus TCP?

  A: Yes, it is explicitly designed for Modbus TCP/IP communication, supporting both master and slave messaging protocols.

• Q: How is the web server functionality accessed?

  A: The module acts as a web server, allowing users to access diagnostics, Rack Viewer, and Data Editor via standard web browsers over the network.

• Q: What is the power requirement?

  A: The module consumes 750 mA at 5 VDC, supplied directly via the Modicon Quantum rack power supply.

• Q: Can I use fiber optics and twisted pair simultaneously?

  A: The module provides both physical interfaces, but usage must follow network topology design rules for the specific Transparent Ready installation.

• Q: What is the storage temperature range?

  A: The storage temperature range is -40 to 85 deg C, ensuring durability during extended non-operational periods.
