Schneider Electric 140NOE77101 Ethernet network TCP/IP module Modicon Quantum,
The Schneider Electric 140NOE77101 is an Ethernet network module designed for the Modicon Quantum PLC series, enabling industrial automation systems to communicate via TCP/IP protocols. Here's a detailed overview:
- Model: 140NOE77101
- Protocol Support:
- Modbus TCP: For industrial device communication.
- TCP/IP: Standard for network connectivity.
- SNMP: Enables network monitoring and management.
- HTTP: For web - based configuration and diagnostics.
- Ports:
- 10/100 Mbps RJ45 (10Base - T/100Base - TX) for copper connections.
- 10 Mbps optical port (10Base - FX) for fiber - optic links (e.g., for longer distances or noise immunity).
- Two Ethernet ports:
- Power:
- Requires 24 V DC power supply.
- Draws approximately 750 mA at 5 V DC from the rack.
- Dual Redundancy:
- Supports hot - standby redundancy for critical applications (e.g., redundant Ethernet networks).
- High - Speed Communication:
- 10/100 Mbps auto - negotiation ensures compatibility with legacy and modern networks.
- Web Server Functionality:
- Built - in web server allows remote configuration, monitoring, and diagnostics via a browser.
- Industrial - Grade Design:
- Rugged construction for harsh environments (e.g., temperature, humidity, vibration).
- Conformal coating on circuit boards for corrosion resistance.
- Memory:
- 8 MB flash memory for storing configuration files and firmware.
- Industrial Automation:
- Connecting PLCs, HMIs, and I/O modules in manufacturing, oil & gas, or power generation.
- Remote Monitoring:
- Enabling SCADA systems to access and control devices over Ethernet.
- Network Segmentation:
- Routing traffic between different subnets (e.g., separating control and enterprise networks).
- Redundant Networks:
- Deploying dual Ethernet paths for fault - tolerant operation.
- Software:
- Configure using Unity Pro software (Schneider Electric’s PLC programming environment).
- Define IP addresses, subnet masks, and gateway settings.
- Web Interface:
- Access the module’s web server via its IP address for real - time status monitoring and diagnostic tools.
- PLC Series:
- Designed for Modicon Quantum PLCs (e.g., 140CPUxxx series).
- Networking:
- Works with both standard Ethernet switches and industrial - grade managed switches.
- Protocols:
- Interoperable with other Modbus TCP devices, SCADA systems, and industrial IoT platforms.
- This module has been discontinued by Schneider Electric.
- Replacement: Consider upgrading to newer models like the 140NOC78100 or BME - NOC0301 (for Modicon M580 PLCs) for enhanced features and support.
- Mounting:
- Install in a Quantum rack with appropriate power and cooling.
- Cabling:
- Use shielded Ethernet cables for noise immunity in industrial settings.
- Fiber - optic connections (10Base - FX) require compatible media converters or switches.
- LED Indicators:
- Monitor status LEDs for power, network activity, and faults.
- Diagnostics:
- Use the web server or Unity Pro to check network connectivity, CPU load, and error logs.
