Installation Guide

1. Install the 140NOC77100 into a standard I/O slot on the Quantum backplane.
2. Connect an Ethernet cable (Cat 5e/6) from the RJ45 port to the industrial Ethernet switch or network hub.
3. Configure IP address, subnet mask, and gateway via Unity Pro or Concept programming software.
4. Set up Ethernet/IP scanner configuration for peer-to-peer communication with other Ethernet/IP devices.
5. Configure Modbus TCP/IP server parameters (port 502) for HMI/SCADA connectivity.
6. Enable SNMP for network management if required by your IT infrastructure.
7. Verify link LED and activity LED on the module front panel.
8. Test communication via ping and Modbus TCP read/write operations.

FAQ

Q: Is 140NOC77100 still in production?
A: No. The 140NOC77100 is discontinued. Schneider Electric recommends the BMENOC0301 as the replacement for new M580 systems. For Quantum systems, consider upgrading to M580 with BMENOC0301.

Q: What is the difference between 140NOC77100 and 140NOE77101?
A: 140NOC77100 is an Ethernet/IP module (supports Ethernet/IP scanner/adapter + Modbus TCP). 140NOE77101 is a Modbus TCP/IP module (Modbus TCP only, no Ethernet/IP). Both provide RJ45 10/100 Mbit/s connectivity but with different protocol support.

Q: What is the difference between 140NOC77100 and BMENOC0301?
A: 140NOC77100 is for Quantum systems (discontinued). BMENOC0301 is for M580 systems (current production), supporting both Ethernet/IP and Modbus TCP simultaneously, with 3 RJ45 ports, RSTP ring topology, QoS, and embedded HTML5 Web server.

Q: How many Ethernet/IP devices can I connect?
A: Up to 128 simultaneous connections total (combined Ethernet/IP + Modbus TCP). The exact distribution depends on your application configuration.

Q: Can I use 140NOC77100 with M580?
A: No. 140NOC77100 is designed for Modicon Quantum racks only. M580 uses BMENOC0301 or BMENOC0311 communication modules.

Q: Does 140NOC77100 support fiber optic?
A: No. The 140NOC77100 has a single RJ45 copper port. For fiber optic connectivity, use an external media converter or consider 140NOC78000 (if available) with SFP fiber option.

Selection Tips

• Quantum, Ethernet/IP + Modbus TCP, RJ45: 140NOC77100 (legacy, if stock available)
• Quantum, Modbus TCP only: 140NOE77101 / 140NOE77111 (with FactoryCast Web server)
• M580, Ethernet/IP + Modbus TCP, 3×RJ45: BMENOC0301 (recommended replacement)
• M580, Ethernet/IP + Modbus TCP, 2×RJ45 + 1×SFP: BMENOC0311
• Always verify: Protocol requirements (Ethernet/IP vs Modbus TCP), number of connections needed, and system platform (Quantum vs M580) before ordering
• For new projects: Migrate to M580 with BMENOC0301 for long-term support
