Schneider Electric 140NOC77100C Modicon Quantum EtherNet/IP Communication Module
The Schneider Electric 140NOC77100C is a rack-mounted EtherNet/IP communication module for the Modicon Quantum Programmable Logic Controller (PLC) architecture. It acts as a network interface, enabling high-speed deterministic messaging, machine control, and distributed data exchange via EtherNet/IP and Modbus TCP protocols. Designed with a conformal coating, this "C" suffix variant provides enhanced resistance against airborne contaminants, moisture, and corrosive atmospheric gases commonly present in demanding industrial facilities.
Network Processing and Capacity
The 140NOC77100C manages up to 128 simultaneous network connections, allowing a Quantum CPU to interface concurrently with multiple field devices, human-machine interfaces (HMIs), supervisory systems, and neighboring PLCs. The onboard protocol engine processes Common Industrial Protocol (CIP) messaging and standard TCP/IP framing directly on the module, insulating the main PLC processor from network overhead and maintaining predictable execution cycle times.
Conformal Coating and Environmental Protection
The conformal coating applied to the internal printed circuit board (PCB) assembly insulates sensitive surface-mount components from humidity, dust, conductive particulates, and hostile industrial chemicals. This protective barrier makes the 140NOC77100C suitable for installation in chemical processing plants, wastewater facilities, metal refining plants, and paper mills, where standard un-coated communication modules risk premature component degradation or electrical shorting.
Hardware Interface and Diagnostics
Equipped with a standard RJ45 port, the module automatically negotiates 10 Mbit/s or 100 Mbit/s transmission speeds across twisted-pair Ethernet media. Diagnostics and network operational statuses are displayed directly on the front panel via LED indicators, providing visual status for backplane communication activity, configuration readiness, link speed, duplex mode, module health, and network connection status.
