When a Packaging Line Stalls, Every Minute Counts
A system integrator faced a familiar problem: a Modicon Quantum rack needed Ethernet/IP connectivity to tie machine control, material handling, and packaging equipment into one network. The existing module could not handle the connection load. The answer was the Schneider Electric 140NOC77100C, a TCP/IP module from the Modicon Quantum automation platform built for exactly this kind of mixed-application environment.
What the 140NOC77100C Delivers
The 140NOC77100C is an Ethernet/IP network module that supports machine control, material handling, packaging, and textile machinery applications. It communicates over EtherNet/IP using twisted pair cabling through an RJ45 10BASE-T/100BASE-TX port. With a transmission rate of 10/100 Mbit/s and support for up to 128 connections, it handles substantial I/O and messaging traffic without bottlenecking the rack.
Communication services include CIP explicit messaging (client messaging), CIP implicit messaging (I/O communication), SNMP agent, and DHCP/BootP server. The module is compatible with all Unity CPUs and draws 500 mA at 5 V DC via the rack power supply. It carries CE marking, UL 508, CSA C22.2 No 142, FM Class 1 Division 2, and IP20 protection.

Where It Fits on the Plant Floor
In material handling, the 140NOC77100C links conveyors and sorters to a central controller over EtherNet/IP, using CIP implicit messaging for real-time I/O. In packaging, it coordinates fillers, sealers, and labelers through one network segment. Textile machinery benefits from the module’s ability to manage multiple connections without additional hardware. The 128-connection capacity means fewer modules per rack, which simplifies panel layout and reduces spare-part inventory.
Integration and Setup Notes
Because the 140NOC77100C uses EtherNet/IP, integrating it into an existing network may require an external gateway or connection module depending on your architecture. Confirm cable types and gateway compatibility with your supplier before commissioning. The module operates in a clean indoor environment free of corrosive chemicals, at altitudes up to 1000m above sea level, and within 0 to 40 degrees Celsius. Mounting follows standard Modicon Quantum rack format. Local signalling uses nine LEDs for bus activity, configuration status, connection speed, link, duplex/collision, module status, network status, and Rx/Tx activity.
