The Ethernet Interface allows you to directly attach the Series 90-70 PLC to an Ethernet
LAN via a user-supplied transceiver and AUI cable, and to communicate with other
PLCs, hosts, and other control devices on the network.
The Ethernet Interface for the Series 90-70 PLC has “client/server” capability. As a “client” it can initiate communications with other Series 90 PLCs containing Ethernet Interfaces. This is done from the PLC ladder program using the COMMREQ function. As a
“server” it responds to requests from other devices such as Logicmaster 90-70 TCP/IP
Ethernet, a Host computer running a Host Communications Toolkit application, or
another Series 90 PLC acting as a “client”. No PLC programming is required for server
operation.
The Ethernet Interface
An operational Ethernet Interface consists of the Ethernet controller board with resident
firmware and the Ethernet Interface software downloaded from the GEnet System Manager .
(It is the TCP/IP-Ethernet software that distinguishes this product from the similar MMSEthernet product.) The Ethernet controller board provides a physical connection from
the PLC to the Ethernet LAN. It also is shipped with on–board diagnostics, a download
program to complement the downloader on the GEnet System Manager , and a utility program that permits testing the cable plant. The controller board becomes a fully functional communications interface only after downloading additional software from the GEnet
System Manager .
Capabilities of the Ethernet Interface
The Ethernet Interface brings to your PLC a great deal of capability . It will allow you to:
H
Directly attach your PLC to an Ethernet network. The Ethernet Interface allows
you to directly attach the Series 90-70 PLC to an Ethernet LAN via a user-supplied
transceiver and AUI cable, and to communicate with host computers and other
Series 90 PLCs on the local network.
H
Transfer data between PLCs. The Ethernet Interface provides client capability, the
capability to initiate communications to other Series 90 Ethernet Interfaces, using
COMMREQ functions in the ladder program.
H
Access data using a Host Computer. Computer applications which use the GE
Fanuc Host Communications Toolkit can access data within the Series 90-70 PLC
through the server capability of the Ethernet Interface. Supported computer
operating systems include Windowst for Workgroups, Windows NTt, HP -UX
9000, DEC VAX/VMSt, and DEC Alpha AXP/VMSt.
H
Communicate simultaneously to multiple devices. The multiplexing capabilities of
the Ethernet Interface, along with Ethernet network’s high capacity, allow the PLC
to communicate with several other devices at the same time.

GFK-1004B
H
Maintain Compatibility with other GE F anuc devices, as well as with devices from
other vendors. The GE Fanuc Series 90–70 PLC with TCP/IP Ethernet Interface is
compatible with the Series 90-30 PLC with TCP/IP Ethernet Interface.
It is also compatible with GE Fanuc Logicmaster 90-70 TCP/IP Ethernet and GE
Fanuc HCT Ethernet products available on DEC, HP, IBM, and other computer
platforms running TCP/IP.
H
Diagnose and maintain your system, using diagnostic and station management
tools. You can find problems before they become serious. In the event that
communications software upgrades are needed, you can use the network or the
built-in serial port to download the software to the interface.
H
Indirectly attach to other Local Area Networks and/or wide area networks via third
party IP routers. When configured to use an IP gateway (router), the Ethernet
Interface can communicate with remote PLCs and other nodes reachable through
the router.
H
Communicate with remote computers via Serial Line Internet Protocol (SLIP)
using modems and/or serial lines. Using third party SLIP software, a remote host
computer can be attached to a TCP/IP network thus allowing it to communicate to
the Series 90 PLC via the Ethernet Interface.
1
Attachment of the Ethernet Interface to the LAN
The A UI port provides the electrical and mechanical interface to the user-provided
Ethernet transceiver cable, which connects the AUI port to an external user-provided
transceiver. The external transceiver is directly connected to the Ethernet cable.
Various Ethernet baseband media (10Base...) can be interconnected by appropriate repeaters. Capabilities and limitations are defined in IEEE 802.3 Chapter 13, “System Considerations for Multi-Segment Networks”.
The Ether net Controller can operate on any of the following media with the appropriate
user-supplied transceiver cable and transceiver. IEEE 802.3 specifies the definitive requirements of each medium.
10Base5 Coax: 10Base5 uses a 0.4 inch diameter 50–ohm coaxial cable. The maximum
length of a cable segment is 500 meters. The distance between any two stations must be
a multiple of 2.5 meters. A maximum of 100 stations is allowed on a thickwire Ethernet
segment.
10Base2 Coax: 10Base2 uses a 0.2 inch diameter 50–ohm coaxial cable. The maximum
length of a cable segment is 185 meters. A maximum of 30 stations is allowed on a thinwire Ethernet segment.
10BaseT: 10BaseT uses a twisted pair cable of up to 100 meters in length between each
node and a hub or repeater. Typical hubs or repeaters support 6 to 12 nodes connected
in a star wiring topology.
GFK-1004B
10BaseF: 10BaseF has two variations that both use the same type of fiberoptic cable:
10BaseFP can support up to 33 nodes at distances of up to 500 meters from a passive
star; 10BaseFL supports up to 2000 meters between a node and a repeater (a multi-port
repeater would thus constitute a star). Additionally, 10BaseFB provides a means of interconnecting (only) repeaters by up to 2000 meters of (the same) fiber optic cable.
Chapter 1 Introduction
1-3
1
10Broad36: 10Broad36 uses 75-ohm coaxial cable and CATV-like media components
(taps, amplifiers, headend translators, etc.) to support hundreds of nodes at distances of
up to 2800 meters. Broadband cannot be connected to baseband via repeaters. Broadband cable plant design and installation must be in accordance with IEEE 802.7 and requires special expertise. GE Fanuc recommends you contract professional specialists for
these services. Consult your GE Fanuc sales representative or field service office for help
in identifying local specialists.
The Ethernet Software
A s stated above, the Ethernet Interface becomes fully functional only after additional software
is download ed from the GEnet System Manager. The downloaded software consists of:
The Station Manager . The Station Manager provides On–Line supervisory access to the
Ethernet Interface, through either the serial port on the controller board or over the
Ethernet cable. These Station Manager services on the Ethernet Interface include:
H
An interactive set of commands for interrogating and controlling the station.
H
Unrestricted access to observe internal statistics, an ex ception log, and configuration
parameters.
H
Password security for commands that change station parameters or operation.
The Ethernet Interface firmware provides some Station Manager
functions. Downloaded software adds commands to provide more
functionality.
Communications Software. This software consists of the TCP/IP protocol stack and interface software interfacing the protocol stack with the PLC.
Configuration File. This configuration data consists of an IP address for the Interface, a
subnet mask, and the IP address of a gateway. This data is overridden by any TCP mode
configuration configured for the Ethernet Interface in the LM90 configurator.
The GEnet System Manager (GSM)
The GEnet System Manager is a menu–driven software package that runs on a user–provided Workmaster or IBM PC. The GSM provides various management and configuration tools. The GSM can be connected to the Ethernet Interface either with a serial RS–232
cable, or over the Ethernet cable. When used over Ethernet, one GSM can conveniently
access any of the Ethernet Interfaces on that cable.
The most essential GSM tools are:
H
The Configuration Editor
Note
H
The Downloader
H
Access to the Station Manager on the Ethernet Interface
In addition, the GSM has the following functions:
H
Examine the list of configured Ethernet Interfaces.
H
Examine and modify network–wide configuration parameters.
1-4 TCP/IP Ethernet Communications User’s Manual – Januar y 1996
GFK-1004B

Note
Typically, there will be only one GSM on the network. It will contain
configuration information and communications software for all the
GEnet stations on the network.
The Configuration Editor
The Configuration Editor is a menu–driven software package that is part of the GSM.
It is used offline to examine and modify configuration parameters for the GE Fanuc Series
90-70 Ethernet Interfaces on your network. These configuration parameters are stored in files
on the PC hard disk and subsequently downloaded to the interface using the GSM
Downloader.
The Downloader
The Downloader is a utility which transfers the Communications Software and the Configuration File to the Ethernet Interface. The Downloader operates in two modes, local (RS232)
and network. The Downloader and the download mode are selected in the main screen of
the GSM.
Access to the Station Manager on the Ethernet Interface
The Ethernet Interface provides an interactive maintenance interface called the Station Manager (described in Chapter 5). The Station Manager allows you to view current and historical information about the operation of the Ethernet Inter face. The GSM provides access to
the Ethernet Interface and Station Manager in both local and network modes. A ccess to the
Station Manager and the access mode are selected in the main screen of the GSM.

diagnostics and its hardware is operating properly .
It is OFF if the module fails a diagnostic test or if a fatal
failure is detected while the board is running.
This LED is blinking if the module is running
diagnostics or is in Soft Switch Entry state.
ББББББББББББББ
If this LED and the ST ATUS OK LED are blinking
ББББББББББББББ
together , diagnostics have completed and the operator
is being given a chance to enter Field Network Test.
ББББББББББББББ
ONLINE is ON when the Ethernet Interface is
connected to and ready to communicate on the network.
This LED is OFF when:
H
the station is not communicating on the network
ББББББББББББББ
due to disconnection or a disruption of the cable.
ББББББББББББББ
H
the local station has malfunctioned, or the
Ethernet Interface has been commanded not to enter
ББББББББББББББ
the network, or is in a state where network operation
ББББББББББББББ
is inappropriate, such as Soft Switch Entry state or
local loading.
ББББББББББББББ
It is BLINKING when the module is transferring data
on the network or loading over the network.
ST ATUS OK is ON if the module is running without

GFK-1004B
Restart Button
The Restart button serves two functions: Restart, and Restart and Reload. The Restart
button is inaccessible when the door to the Ethernet Controller board is closed.
Restart: Pressing the Restart button (for fewer than 5 seconds) forces a restart of the
Ethernet Interface. The power-up diagnostics run and the software on the module is
restarted when the pushbutton is released.
Restart and Reload: Pressing and holding the Restart button for 5 seconds or more
forces a restart and requests a reload of the Ethernet Interface. When the Restart button
is pressed, all LEDs go out. After 5 seconds have elapsed, the STATUS OK LED comes
ON, to indicate that the Ethernet Inter face will request a reload. After the Restart pushbutton is released, the power-up diagnostics run and the Ethernet Interface requests to
be loaded.

In either case, any data being transferred by the Ethernet Interface at
the time of the Restart will be lost.
The Restart Pushbutton will not be operable during the Ethernet
Controller board diagnostic phase. The Ethernet Controller board is in
diagnostic phase when the BOARD OK LED is BLINKING and the
ONLINE and STATUS OK LEDs are off.
When connected, the battery preserves the contents of RAM when there is no power to
the board. The battery will maintain RAM contents for a minimum of six months.
Warning
The lithium battery presents a fire, explosion, or severe burn risk. Do
NOT: recharge it, remove its polarized connector, disassemble it, heat
it above 100C (212F), incinerate it, or expose its cell contents to water.
Dispose of the battery as required by applicable ordinances or
regulations. When replacing the battery, use only Catalog No.
IC697ACC701. Use of another battery could result in ignition or
explosion of the battery. Replacement batteries can be ordered from
GE Fanuc Automation - NA or any GE Fanuc Authorized Distributor.
Serial Port
The 9-pin serial port (RS-232 interface) is used to connect to the GEnet System Manager
(GSM). The communication software on the distribution diskette may be loaded
through this port. A cable is needed to connect the GSM to the Ethernet Interface (see
Appendix B, Communications Ports Characteristics). The faceplate of the Ethernet Interface must be open to connect the cable. The serial port may also be used with a serial
terminal for local Station Management.
AUI (Transceiver) Port
The 15-pin AUI port provides the electrical and mechanical interface to the user-provided IEEE 802.3 transceiver cable, which connects the AUI Port to an external Ethernetcompatible transceiver (see Appendix B for the characteristics of the AUI Port). The external transceiver is directly connected to the Ethernet cable.
Default Station Address Label
The Default Station Address label lists the station address to be used by this module, unless changed by the user via soft switches.

2
Press firmly to lock the board in place, but do not force the board.
Note
The Ethernet Controller board will not operate properly if there are
empty slots to the left of the slot you select.
5. Connect the free end of the safety wire (18 inch long green wire attached to the
Ethernet Controller board) to the ground lug at the side of the Series 90-70 PLC rack.
(See Figure 2-2).
Warning
The ground wire must be securely fastened to the chassis of the Series
90-70 PLC rack and the rack must be properly grounded. Failure to do
so may cause personal injury and/or improper operation of the LAN.
6. Connect the transceiver cable into the 15-pin AUI Port of the Ethernet Controller
board. Secure the cable with the slide latch mechanism. The other end of the
transceiver cable should be connected to an external IEEE 802.3 compatible
transceiver which is attached to the Ethernet network. SQE must be enabled on the
transceiver.
7. Set the CPU Run/Stop switch to STOP.
8. Continue with Procedure 2: Verifying Ethernet Interface Power-Up.

Procedure 2: Verifying Proper Power-Up of the Ethernet Interface
Before powering–up the Ethernet Interface, you may wish to connect the GEnet System
Manager (GSM) locally to the Ethernet Interface, and select the “Station Manager” func-
tion from the GSM Main menu. This allows you to observe the progress of the power–
up diagnostics via the Station Manager software on the Ethernet Interface. The GSM is
also used to perform other operations in subsequent Installation Procedures.
Refer to Chapter 3, “The GEnet System Manager”, for instructions on installing the GSM
software on a user-supplied PC-compatible computer .
Note
Alternately, you can use a dumb terminal, or another terminal
emulation product on a PC. However, you will probably find it most
convenient to use the GSM since you will be using the GSM for other
configuration purposes in subsequent steps.
2
If you do not use the GSM, configure the terminal for 9600 bps, 8 bits, no
parity, and 1 stop bit. See Appendix B, for instructions on making the
serial cable.
Using the GSM “Access Station Manager” Function
The Station Manager software on the Ethernet Inter face is accessed by connecting the
Ethernet Interface to a Workmaster or other computer running the GSM software and
selecting the “Station Manager” function from the GSM main menu.
1. There are two ways the GSM can be physically connected to an Ethernet Interface:
Local Connection and Network Connection.
Note
To observe the progress of Power–Up Diagnostics described in this
procedure and to invoke the Field Network Test Utility described in
Installation Procedure 5, the GSM must be connected locally and put in
the Local Station Manager Mode.
A. GSM Using Local Connection. Connect the COM1 RS–232 serial port on the
device running the GSM to the 9–pin connector on the Ethernet Inter face. Refer
to Appendix B, for instructions on how to make the RS–232 cable.
GFK-1004B
B. GSM Using Network Connection. Connect the Ethernet card on the device
running the GSM to the Ethernet Network.
C. For now, use the Local connection.
2. Power–up the computer (on which you have previously installed the GSM software)
into DOS. Refer to Chapter 3 for the GSM installation procedure.
Chapter 2 Installing the Ethernet Interface

3. Set the PC default directory to the GSM directory, by typing:
C:\> cd \gsm
4. Start–up the GSM by typing:
C:\GSM> gsm
5. At the password screen, type in the password. The default password is “gsm”.
6. Once the GSM Main Menu appears, go into the Setup GSM functions to set the
Station Manager communications mode to Local, exiting with <ALT-U>.
7. From the GSM Main Menu, cursor to the “Station Manager” function and press
Enter to select.
If you selected Local Mode in step 6, the GSM will automatically access the Station
Manager of the locally connected Ethernet Interface. If you are prompted for
“Station Name”, you did not select Local Station Manager mode. Repeat step 6.
States of the Ethernet Interface
The figure below shows the 5 possible states of the Ethernet Interface. The states are
distinguished by LED patterns and by unique Station Manager NODE command and
prompt outputs.

The Ethernet Interface will normally transition from the Power–Up State to the Operational State without entering any other state.
If there is a problem with the Soft Switch data, however, the Ethernet Interface will transition automatically to the Soft Switch Entry utility (see Appendix C for instructions).
And if you have not previously downloaded a station configuration to the Ethernet Interface, the Ethernet Interface will transition automatically to the Loader utility (see Procedure 4 for instructions). Also, the operator may manually cause the Ethernet Interface
to enter the Field Network Test utility.
Powering-Up the Ethernet Inter face
Follow the procedure below to verify that the Ethernet Interface is operating correctly.
1. P ower–up the PLC. This will initiate a series of diagnostic tests.
Upon power–up the Module OK LED blinks, On Line and Status OK LEDs are OFF.
2. Obser ve the local Station Manager screen if connected. If power–up is successful,
then a Station Manager message similar to the following will be displayed, normally
within 15 seconds
