140NOE77101 - Ethernet Network TCP/IP Module, Modbus TCP, 10/100 Mbps, Single Slot

Product type: Ethernet Network TCP/IP Module  |  Range: Modicon Quantum  |  Ports: RJ45 + 100BASE-FX fiber

The 140NOE77101 is an Ethernet network TCP/IP module for the Modicon Quantum automation platform. It plugs into one standard slot of a Quantum local or remote rack and connects the controller to an Ethernet network, so that the PLC, the SCADA system and the plant network exchange data over Modbus TCP/IP. The module is a Transparent Ready device of class B30 with an embedded web server, which means diagnostics and rack information are reachable from a browser without additional software. It occupies a single slot, is 40.3 mm wide on the rack, 250 mm high and 103.9 mm deep, and is powered from the rack backplane.

Two physical network interfaces are provided on the front panel: one RJ45 port for 10BASE-T / 100BASE-TX twisted pair, and one MT/RJ port for 100BASE-FX fiber optic. Transmission rate is 10/100 Mbit/s, and the module works with the Ethernet Modbus TCP/IP protocol. Fiber is used where the run crosses a high interference area or exceeds the distance a copper segment can cover. The module supports a hot standby redundant architecture, which is why it is commonly used on installations where a single network failure must not stop the process.

Communication services include Modbus TCP messaging, I/O scanning, Global Data for periodic data exchange between PLCs, bandwidth management, SNMP network management and an FDR server for automatic replacement of a faulty device. The embedded web server publishes predefined diagnostic pages, a rack viewer and a Data Editor that is used from a PC terminal. Eleven LEDs on the front panel show data rate, collision, download mode (Kernel), module fault, network status (RUN), full duplex, module ready, link, rack active and transmit/receive activity, so a fault can be located without a programming terminal.

The module draws 750 mA at 5 V DC from the rack power supply and needs no external supply or wiring other than the network cables. It is a standard format module, so it can be placed in any free Quantum slot of the appropriate rack, and the module is marked CE. Protection degree is IP20, which means it is designed for mounting inside a closed enclosure rather than on the machine frame.

Operating temperature is 0 to 60 °C, storage temperature −40 to 85 °C, relative humidity 95 % without condensation, and operating altitude up to 4500 m. Resistance to electrostatic discharge is 4 kV on contact and 8 kV on air to IEC 801-2, and resistance to electromagnetic fields is 10 V/m over 80 to 1000 MHz to IEC 801-3. The module is certified cUL and UL 508, conforms to CSA C22.2 No 142 and is approved for FM Class 1 Division 2 hazardous locations.
