Schneider Electric 140NOC77100C Modicon Quantum Communication Modules

Configured for high-speed Ethernet/IP network integration in Modicon Quantum automation platform backplanes, the Schneider Electric 140NOC77100C (140NOC77100C Communication Module) provides direct physical/electrical execution. It manages deterministic cyclic and explicit messaging up to 100 Mbit/s between Quantum controllers and field devices across distributed network topologies.

Suffix Breakdown & Model Matrix

Hardware Specifications

Backplane Bus & Deterministic Networks

The module integrates directly with the Modicon Quantum backplane bus, receiving operating power while ensuring firmware flash compatibility with Quantum processor units. Utilizing 1500 V galvanic isolation across its Ethernet interface, the unit suppresses noise coupling and prevents ground potential loops from degrading high-speed Ethernet/IP deterministic networks. The module manages up to 64 concurrent implicit and explicit messaging paths, transferring 1024 bytes of input data and 1024 bytes of output data per cycle without backplane bus communication latency or buffer overflow.

Frequently Asked Questions

Q: How does the internal 220 uF capacitor function during power fluctuations?

A: The onboard 220 uF capacitor provides energy storage to bridge brief 24 VDC supply interruptions, allowing the processor and network interface logic to retain memory state and shut down cleanly without corrupting configuration files.

Q: What diagnostic capabilities are integrated into the 140NOC77100C module?

A: Real-time diagnostics are provided through front panel LEDs indicating network activity and fault states, alongside an embedded HTTP web server that delivers browser-based connection status, port health, and error statistics.

Q: What is the purpose of the 'C' suffix in the 140NOC77100C catalog number?

A: The 'C' suffix specifies factory-applied conformal coating on the internal printed circuit board assembly, extending hardware resilience against moisture and chemical contaminants in harsh ambient environments.

Field Installation Guidelines

1. Insert the module into an open slot on the Modicon Quantum rack backplane and secure the retention latch.
2. Connect shielded twisted-pair (STP) Ethernet cabling to the RJ45 port, maintaining separation from 230 VAC power leads.
3. Ground all cable shielding directly to the panel earth bus bar to maintain the 1500 V isolation barrier.
4. Supply 24 VDC external power to the module, verifying that current limits satisfy the 250 mA nominal requirement.
5. Assign network IP addresses via DHCP server or static configuration software before connecting to the active industrial network.
