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. Broad-
band cable plant design and installation must be in accordance with IEEE 802.7 and re-
quires 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
As stated above, the Ethernet Interface becomes fully functional only after additional software
is downloaded 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 exception log, and configuration
parameters.
H Password security for commands that change station parameters or operation.
Note
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 in-
terface 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–pro-
vided Workmaster or IBM PC. The GSM provides various management and configura-
tion 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
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.
