Overview
The following information provides overviews of all Modicon Quantum Ethernet modules.
General Description
The Modicon Quantum Ethernet module, shown below, is one of the latest models in a line of Modicon Quantum Ethernet TCP/IP modules designed to make it possible for a Modicon Quantum PLC to communicate with devices over an Ethernet network. The electronics for the Ethernet modules are contained in a standard Modicon Quantum single-width case that takes up one slot in a Modicon Quantum backplane. The module, which is capable of being hot swapped, can be plugged into any available slot in the backplane.
The NOE 771 x0 and NOE 771 x1 modules provide real-time peer-to-peer communications and I/O scanning and a Modbus/TCP server. The included HTTP services provide maintenance and configuration utilities to the module.

NOTE: In the detailed description of the key features, only modules in the NOE family are named. The features are also available for the 140 NWM 100 00 module, depending on the listed properties in the above table.
NOTE: In Control Expert software, the 140 NWM 100 00 module is set in the TCP/IP Regular Network family, although it belongs to the TCP/IP FactoryCast network family. So, the services listed above (I/O scanning, Global Data, address server, Bandwidth monitoring) are not supported by the module. However, they can be selected in the TCP/IP regular network configuration in Control Expert. (Even if they are configured, those services won't work with the module.)

Front Panel Components
The front panel of the Ethernet modules contains identification markings, color codes, and LED displays. A writable area for an IP address, a global address label, and two Ethernet cable connectors is located behind the removable front panel door.
The following table provides a description of the front panel components that are shown in following figure:
Component
Description
LED Indicator Panel
Indicates the operating status of the module, and the fiber optic or Ethernet communications network to which it is connected.
IP Address Area
Provides a writable area to record the module’s assigned IP address.
Global Address Label
Indicates the module’s global Ethernet MAC address assigned at the factory.
100 BASE-FX Connector
Provides an MT-RJ socket for connection to a 100-megabit fiber-optic Ethernet cable.
10/100 BASE-T Connector
Provides an RJ45 socket for connection to a shielded, twisted pair Ethernet cable.
