IC693NIU004

Product Description

The IC693NIU004 is a GE Fanuc 90-30 series Ethernet Network Interface Unit.  This operates as an Ethernet Global Data station (EGD), exchanging input and output data, status and control data over the network. The unit comes with 8 LEDs, an ethernet restart push button, 3 port connectors, and a shield ground connection tab. The Mac Address label can be located on the outside of the module. The IC693NIU004 ENUI comes with 8 LEDs.  The EOK, LAN, STAT and PS port indicate the status of the module. The other four LEDs are linked to the two RJ-45 ports. The power supply LED is not related to the ethernet ports but only indicates the presence of traffic through the serial ports of the module’s power supply. The EOK, LAN and STAT LEDs can be On/OFF Blinking slow or Blinking fast. These indicate the status of the Ethernet interfaces, traffic at the Ethernet ports (LAN LED) and that an exception event has occurred. Every RJ-45 ports comes with 2 LEDs just as you would find on a PC’s RJ-45 port. The one labelled LINK/ACT comes on when the link is physically present and blinks when traffic is detected on that port. The other indicator labeled 100Mbps comes on to indicate that the connection is 100Mbps

The ethernet restart push button has 2 functions: performing the LED test and restart. Pressing the Ethernet restart push button will have the effect of disrupting ethernet communications, this includes any communication to other devices attached to the embedded switch. When the Ethernet restart pushbutton is pressed, the 7 LEDs come on simultaneously. One should ensure that the LEDs go OFF and ON. The interface then performs a restart. Power diagnostics run and interface’s software is restarted to operational state.

The RS-232, 6-pin, RJ-11 port is for connecting a terminal or terminal emulator to access the station manager software on the ethernet interface. The Station Manager feature is used for testing and troubleshooting Ethernet communications. Its use is, however, optional. A IC693CBL316A cable is used for connecting the terminal, emulator or software loader to the ethernet. The user can find 2 RJ-45 Ethernet ports on the NIU. One or both may be attached to other ethernet devices. Each port automatically senses data rate (10Mbps or 100Mbps), half or full duplex and cabling arrangement: either straight through or crossover. Cables used to connect to the ENUI can be either shielded or unshielded, direct or crossover. It should be noted that the two ethernet ports should not be connected to the same device as this will lead to duplication of packets. Before the Ethernet NIU is used on the network, it must be configured using the CIMPLICITY Machine Edition Logic Developer software. This is used for:

• Assigning an IP address to the ENUI
• Defining subnet mask, default gateway and name server address
• Setting up Ethernet Global Data Exchange messaging between the ENIU and controller(s)

Installing the Ethernet NIU in the CPU Baseplate

• Ensure that the baseplate power is turned OFF.
• Align the module with slot 1 and the connector. Tilt the module up so the top rear hook of the module engages the slot on baseplate.
• Swing the module down until the connectors mate and the locking lever on the bottom of the module snaps into place, engaging the baseplate notch.
• Do Check the module to be sure that it is properly seated.
• Connect one or both Ethernet ports on the Ethernet Interface to the network.
• Restore power to the baseplate.

Technical Specifications

The GE Fanuc IC693NIU004 Ethernet Network Interface Unit is an Ethernet network interface module made for the RX3i PACSystems and the Series 90-30 Ethernet remote I/O expansion systems. This network interface module operates as a networked EGD station for the exchange of I/O data, operation status data, and control process data over the high-speed industrial Ethernet network. The IC693NIU004 Module can be installed in any of the Series 90-30 and RX3i CPU baseplate slots, and together with the RX3i or the Series 90-30 selected I/O modules, it forms the whole remote I/O station. The GE Fanuc RX3i controllers support Ethernet remote I/O systems via the IC693NIU004 Ethernet Network Interface Unit. In the Series 90-30 PLC system, I/O modules can easily be selected as slave devices for specific applications over the Ethernet network by using the IC693NIU004 Ethernet Network Interface Unit.
 

The IC693NIU004 Module has 3 network ports 1 RJ-11 ES-232 Serial port and 2 RJ-45 Ethernet ports, 8 LEDs, an Ethernet restart pushbutton, a redundant key switch, and a shield ground connection tab on the front of the module. The front-panel RS-232 serial port is used to connect a terminal or terminal emulator for easy access to the Station Manager software over the Ethernet Interface by using the IC693CBL316A Ethernet network cable. The IC693NIU004 Module’s dual Ethernet ports are 10-BASE-T/100-BASE-Tx ports with an auto-negotiating full-duplex capability, which automatically senses the data rates (10 Mbps or 100 Mbps), the duplex configuration, and the cabling configuration (straight-through or crossover) of the attached link when connected to the network. The IC693NIU004 Module has a battery-backed internal clock, and it gets its power requirements (7.4 Watts, 5 Volt DC) from an installed high-capacity power supply. The IC693NIU004 Module is configured by using the CIMPLICITY Machine Edition Logic Developer software.
