The general term,
Interfaces require the more specific terms.
The Series 90-30 PLC CPU 364 and CPU374 are both modules that contain a PLC CPU and an
embedded Ethernet Interface. The general term Embedded Ethernet Interface will be used in this
manual to refer to these modules.
This chapter provides an overview of the Ethernet Interface and covers the following topics:

The Ethernet Interface
The Ethernet Interface enables Series 90 PLCs to communicate with other Series 90 PLCs, with
with GE Fanuc PLC programming software, and with applications developed using the SRTP
protocol, such as CIMPLICITY® HMI.
The Ethernet Interfaces described in this manual have “client/server” capability. As a “client” the
Interfaces 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” the
Interfaces respond to requests from other devices such as PLC programming software, a Host
computer running an SRTP application, or another Series 90 PLC acting as a “client”. No PLC
programming is required for server operation.

Capabilities of the Ethernet Interface
The Ethernet Interface brings to your PLC a great deal of capability. It will allow you to:
Become operational quickly. The Ethernet Interface is made operational with very little effort.
You need only install the Interface in the PLC rack or baseplate and use the PLC
programming software to store basic configuration information to the module to make the
basic SRTP server capability functional. SRTP Client capability, the capability to initiate
communications, can be added using the COMMREQ function in the ladder program. For
Series 90-30 Ethernet Interface IC693CMM321-FH and later, basic Modbus/TCP server
capability is available as soon you supply basic configuration information to the module, and
you can use COMMREQs to initiate Modbus/TCP communications.
Directly attach your PLC to an Ethernet network. The Ethernet Interface allows you to directly
attach the Series 90 PLC to an Ethernet LAN via the built-in network ports or via a usersupplied transceiver and AUI or AAUI cable, and to communicate with host computers and
other Series 90 PLCs on the local network.
Ethernet Global Data. (Series 90-30 CPU364 and CPU374 and Series 90-70 Ethernet
Interface (Type 2) only.) When used with the latest Series 90 CPUs, the Ethernet Interface
provides highly efficient periodic data transfer between PLCs using Ethernet Global Data
exchanges.
Transfer data between PLCs.
to initiate communications to other Series 90 Ethernet Interfaces, using COMMREQ
functions in the ladder program.
Access data using a Host computer.
access data within the Series 90 PLC through the server capability of the Ethernet Interface. .
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.
Maintain compatibility with other GE Fanuc devices and devices from other vendors. The
Series 90-30 Ethernet Interface, Series 90-30 CPU364 Embedded Ethernet Interface, Series
90-30 CPU374 Embedded Ethernet Interface, and Series 90-70 Ethernet Interface (Type 2)
are compatible with each other. They are also compatible with GE Fanuc programming
packages supporting TCP/IP Ethernet communications.
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 a built-in serial port to download the software to the
Ethernet Interface.
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.
Communicate with remote computers via Serial Line 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.
Communicate with other Series 90 PLCs using symbolic names as well as IP addresses.
COMMREQs can be programmed to communicate with PLCs using IP addresses or Network
Address names (Series 90-30 Ethernet Interface, Series 90-30 CPU364 Embedded Ethernet
Interface, and Series 90-70 Ethernet Interface (Type 2)).

and Series 90-70 IC697CMM742 Ethernet Interface (Type 2))
The 10Base-T port 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.
Auto-sensing 10 Base T / 100 Base TX, RJ-45 Port
The auto-sensing 10 Base T / 100Base TX ports are connected to a switch device embedded in the
Ethernet Interface. They use a twisted pair cable (unshielded or shielded) of up to 100 meters in
length between the node and another node, a hub, a repeater, or a switch. The port automatically
senses the speed (10Mbps or 100Mbps), duplex mode (half duplex or full duplex) and cable
(straight-through or crossover) attached to it with no intervention required.
10Base2, BNC port
The 10Base2 port uses a 0.2 inch diameter 50-ohm coaxial cable and is commonly called “thin
wire”. The maximum length of a cable segment is 185 meters. A maximum of 30 stations is
allowed on a 10Base2 Ethernet segment.
AUI Port
AAUI Port
The AUI and AAUI ports provide the electrical and mechanical interface to the user-provided
Ethernet transceiver cable, which connects the AUI or AAUI port to an external user-provided
transceiver. (The transceiver cable may be separate or built-in to the transceiver.) The external
transceiver is directly connected to the Ethernet cable.

Ethernet Media
Various Ethernet baseband media (10Base...) can be interconnected by appropriate hubs or
repeaters. Capabilities and limitations are defined in IEEE 802.3 Chapter 13, “System
Considerations for Multi-Segment Networks”. This document is published by the Institute of
Electrical and Electronics Engineers, Inc., 345 East 47th Street, New York, NY 10017-2394 USA.
The Ethernet Interface can operate on any of the following media with the appropriate usersupplied transceiver cable and transceiver. IEEE 802.3 specifies the definitive requirements of
each medium.
1
10Base5 Coax:
“thick wire”. 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
10Base5 Ethernet segment.
10Base2 Coax:
10Base-T:
10Base-F:
10Base-FP can support up to 33 nodes at distances of up to 500 meters from a passive star;
10Base-FL supports up to 2000 meters between a node and a repeater (a multi-port repeater
would thus constitute a star). Additionally, 10Base-FB provides a means of interconnecting
(only) repeaters by up to 2000 meters of (the same) fiber-optic cable.

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.

Special Considerations for Ethernet Interfaces with Embedded Switches
Ethernet Interfaces that incorporate embedded switches (only the Series 90-30 CPU374) provide
some additional connection options and have some additional installation and operation
considerations.
These Ethernet Interfaces provide two RJ-45 connectors on the front of the module. It is
important to realize that there is only one interface to the network (only one Ethernet address and
only one IP address) provided by these Ethernet Interfaces. The two connectors allow up to two
Ethernet devices (hubs, switches, other PLCs, PCs) to be connected to the Ethernet Interface. This
arrangement is diagrammed below.

It is also possible to daisy-chain PLCs together without additional components, but that should be
done with great care. In designing a system, remember that a loss of power or reset on any
Ethernet Interface in a daisy chain will cause loss of communications with all devices
downstream from the lost module.
The second port, if left unused, can be used to plug in a programmer over Ethernet.
Caution
The two ports on the Ethernet Interface must not be connected, either directly or indirectly,
to the same device. The hub or switch connections in an Ethernet network must form a tree,
otherwise duplication of packets may result.
1-6 TCP/IP Ethernet Communications for the Series 90™ PLC User's Manual – May 2002 GFK-1541B
The Station Manager Software
The built-in Station Manager software provides on-line supervisory access to the Ethernet
Interface, through either the Station Manager port or over the Ethernet cable. The Station
Manager services on the Ethernet Interface include:
An interactive set of commands for interrogating and controlling the station.
Unrestricted access to observe internal statistics, an exception log, and configuration
parameters.
Password security for commands that change station parameters or operation.
Access to the Station Manager is attained through a user-provided computer terminal or terminal
emulator. See GFK-1186,
Manager Manual
, for more information on the Station Manager.
The PC Software Loader
The PC Software Loader is a separate software utility which runs on a PC in order to update the
communications software stored in flash memory in the Ethernet Interface. This utility is
supplied with any updates to the Ethernet Interface software.

Installing an IC693CMM321 Ethernet Interface Module
The IC693CMM321Ethernet Interface mounts in a Series 90-30 PLC baseplate. It connects to an
Ethernet network either directly through its 10Base-T port (10Base-T Type only), or through its
AAUI port, which requires a user-provided transceiver and cable. If using the AAUI port, you
may order a transceiver from GE Fanuc (see Appendix B for information) or supply your own
equivalent transceiver. .

OK State of the Ethernet Interface
LAN Traffic on the network port
FDX Configuration of Full Duplex mode.
STAT An exception event has occurred
All LEDs are briefly turned ON whenever a restart is performed in the Operational state by
pressing and releasing the Restart pushbutton (described below). This allows you to verify that all
LEDs are operational. (On module versions EF or earlier, the FDX LED is labeled "SER".)
Restart Pushbutton
The Restart pushbutton serves four functions: LED test, Restart, Restart and enter Software Load
state, and Restart and enter Maintenance state. These four functions behave similarly in all states
except for the Software Load state. While in this state, pressing the pushbutton will cause an
immediate restart into the Operational state (without performing the LED test) if the software in
the Ethernet Interface has not been corrupted or erased. If the software has been corrupted or
erased, pressing the pushbutton will cause an immediate restart back into the Software Load state.
The following text describes Restart pushbutton behavior while not in the Software Load state.

Restart and Enter Software Load State:
bottom LED (STAT) turns ON (between 5 and 10 seconds) forces a restart and requests entrance
to the Software Load state. A reload is used to install a software update into the module and is
not part of normal operation. When the Restart pushbutton is pressed, all LEDs go out. After
approximately 5 seconds have elapsed, the STAT LED (bottom LED) comes ON, to indicate that
the Ethernet Interface will request a reload. After the Restart pushbutton is released, all LEDs
flash ON, then power-up diagnostics run, and the Ethernet Interface waits for the software load
with all LEDs blinking in unison.
Pressing and holding the Restart pushbutton until the
Notes
Reloading the Ethernet Interface requires the attachment of the PC Software
Loader to the Software Loader port and initiating a load with the PC Software
Loader. The PC Software Loader is a separate software utility that updates the
communications software in the Ethernet Interface. This utility is supplied with
any updates to the Ethernet Interface software.
At any time before you initiate a load with the PC Software Loader when the
Ethernet Interface is in the Software Load State, you can restart the Ethernet
Interface by pressing the Restart pushbutton. Pressing this pushbutton will
immediately cause the board to restart. If the reload has been initiated, see
Appendix C, “Upgrading the Ethernet Interface Firmware,” for more
information.
Restart and Enter Maintenance State:
bottom two LEDs turn ON (approximately 10 seconds) forces a restart and requests entrance to
the Maintenance state. Maintenance state must be invoked to change Advanced Parameters.
While in Maintenance state, all Advanced Parameters revert to their default value. When the
Restart pushbutton is pressed, all LEDs go out. After approximately 5 seconds, the STAT LED
comes ON, then after approximately a total of 10 seconds have elapsed, the FDX LED also comes
ON, to indicate that the Ethernet Interface will request entry to the Maintenance state. After the
Restart pushbutton is released, all LEDs flash ON then power-up diagnostics run and the Ethernet
Interface enters the Maintenance state.
Pressing and holding the Restart pushbutton until the
Notes
If a Restart is performed, any data being transferred by the Ethernet Interface at
that time will be lost.
The Restart pushbutton is not operable during the diagnostic phase of power-up.
The Ethernet Interface is in diagnostic phase when the OK LED is BLINKING
fast and other LEDs are OFF.

Ports on the CMM321
RS-232, RJ-11 Port (Station Manager Port)
The RS-232, 6-pin, RJ-11 “phone jack” port is used to connect a terminal or terminal emulator to
access the Station Manager software on the Ethernet Interface. A cable is needed to connect the
terminal or emulator to the Ethernet Interface (see Appendix B, “Communications Ports
Characteristics”). This port is also used to update the module’s firmware.
Ethernet Ports
The CMM321 has just one Ethernet interface. Connection to the Ethernet network can be made
either through the 10Base-T connector or the AAUI connector. You must connect to just one or
the other connector; you cannot use both at the same time. Note that module versions EF and
earlier do not have a 10Base T port, and can only be connected through their AAUI port.
10Base-T Port
This port is located on the front of the module and it can be directly connected to a 10Base-T
network (no external transceiver is needed). It uses a standard RJ-45 jack. See Appendix B for
port details.
2
AAUI (Transceiver) Port
This port uses a standard 14-pin AAUI connector to provide the electrical and mechanical
interface to a user-provided IEEE 802.3 transceiver. See Appendix B for Port details.
Caution
Do not connect or disconnect a transceiver cable at the AAUI port while
power is applied to the PLC. This may blow the AAUI port fuse and/or
cause permanent damage to the Ethernet Interface.
CMM321 Labels
Default Station Address Label
The Default Station Address label lists the MAC address to be used by this Interface.
Serial Number Label
The Serial Number Label indicates the serial number of this Interface.
Non-Replaceable AAUI Fuse
A non-replaceable fuse is provided on the DC power that is supplied by the Ethernet Interface to
the AAUI network port for use by an external transceiver. If this fuse blows, you must return the
Ethernet Interface to GE Fanuc for repair.

CMM321 Installation
Use the following instructions as a guide when inserting a module into a slot in a baseplate.
These instructions assume that the power supply on the baseplate is to your left.
Warning
Do not insert or remove modules with power applied. This could cause the
PLC to Stop, damage the module, or result in personal injury.
1. Be sure the Series 90-30 PLC baseplate power is OFF.
2. Align the module with the desired base slot and connector. Tilt the module upwards so that
the top rear hook of the module engages the slot on baseplate.
3. Swing the module downward until the connectors mate and the lock-lever on the bottom of
the module snaps into place engaging the baseplate notch.
4. Visually inspect the module to be sure that it is properly seated.
5. Connect the cable using one of the two following methods:
• If using a 10Base-T connection, plug the cable into the 10Base-T port on the front of the
module.
2
• If using the AAUI connection, connect the transceiver cable into the 14-pin AAUI port
on the bottom of the module, secure the cable, and connect the other end of the cable to
an external IEEE 802.3 compatible transceiver that is attached to the Ethernet network.
SQE must be enabled on the transceiver. (Note: The transceiver cable may be either
built-in to the transceiver or removable.)
Caution
Do not connect or disconnect a transceiver cable to the AAUI port while
power is applied to the PLC. This may blow the AAUI port fuse and/or
cause permanent damage to the Ethernet Interface.
6. Use the PLC programming software or a Hand Held Programmer to make sure the PLC CPU
is in Stop mode.

Configuring Full-Duplex Operation
Before setting the module to Full-Duplex operation, be certain that it is connected directly to a
managed hub or switch that is manually configured for full-duplex operation on the port
connected to the IC693CMM321.
The default setting for the module is Half-Duplex. The Full Duplex parameter is an “advanced
user parameter” that can only be changed by using the CHPARM (Change Parameter) command
in the Station Manager softwar. Refer to GFK-1186, the
Station Manager Manual
, for additional information on using Station Manager.
TCP/IP Ethernet Communications
Warning
Contrary to the recommendation of IEEE Std. 802.3, this Ethernet Interface
module does NOT support autonegotiation of half/full-duplex. Attempting fullduplex operation of this interface with a repeater or half-duplex network
(including auto-negotiating hubs and switches) can cause severe network
performance degradation, increased collisions, late collisions, CRC errors, and
undetected data corruption.
If the module is configured in the Full-Duplex mode (see above), you can change it back to its
default value of Half-Duplex by using the Station Manager CHPARM command.

The Series 90-30 CPU364 has several user-accessible elements (only the Ethernet Interface
elements are discussed here.)
Three Ethernet LEDs are located at the top left of the board. The Ethernet Restart pushbutton is
located below the LEDs. The RS-232 serial port with the RJ-11 connector (similar to a modular
telephone connector) is used to connect to Station Manager and to load software updates. Below
the serial port are two ports, either one of which can be used to connect to the Ethernet network:
the 14-pin AAUI connector (Transceiver port) and the 10Base-T, RJ-45 network port.
The default station address (MAC address) label, serial number label, and replaceable AAUI port
fuse are concealed by the front cover. The front cover must be removed to access these items.
2-16 TCP/IP Ethernet Communications for the Series 90™ PLC User's Manual – May 2002 GFK-1541B
LEDs
There are four LEDs on the CPU364: EOK, LAN, STAT, and PS PORT (on some early models
of the CPU364, the PS PORT LED is labeled “SNP”). The PS (Power Supply) PORT LED is not
Ethernet related; it indicates the presence of serial traffic through the serial port of the PLC’s
power supply. Each of the three Ethernet LEDs (EOK, LAN, and STAT) can be ON, OFF,
BLINKING slow, or BLINKING fast. They indicate the state of the Ethernet Interface, traffic on
the network port (LAN LED), and that an exception event has occurred.
The three Ethernet LEDs are briefly turned ON whenever a restart is performed in the Operational
state by pressing and releasing the Restart pushbutton (described below). This allows you to
verify that the Ethernet LEDs are operational.
Ethernet Restart Pushbutton
The Ethernet Restart pushbutton serves four functions: LED test, Restart, Restart and enter
Software Load state, and Restart and enter Maintenance state. These four functions behave
similarly in all states except for the Software Load state. While in this state, pressing the
pushbutton will cause an immediate restart into the Operational state (without performing the
LED test) if the software in the Ethernet Interface has not been corrupted or erased. If the
software has been corrupted or erased, pressing the pushbutton will cause an immediate restart
back into the Software Load state. The following text describes Restart pushbutton behavior
while not in the Software Load state.
2
Pressing the Ethernet Restart pushbutton will disrupt Ethernet communications.
LED Test:
ON. The operator should visually verify that the three LEDs go OFF and then ON at this time.
Then the Interface performs either a restart, a restart and enter Software Load state, or a restart
and enter Maintenance state, depending on the duration that you press the pushbutton.
Restart:
restart of the Ethernet Interface. When the Restart pushbutton is pressed, the three Ethernet LEDs
go out. When it is released, the three Ethernet LEDs flash ON, then power-up diagnostics run,
and the software on the Interface is restarted into the Operational state.
Any time the Ethernet Restart pushbutton is released, the three Ethernet LEDs flash
Pressing the Ethernet Restart pushbutton momentarily (less than 5 seconds) requests a
GFK-1541B Chapter 2 Installation 2-17

Restart and Enter Software Load State:
bottom LED (STAT) turns ON (between 5 and 10 seconds) forces a restart and requests entrance
to the Software Load state. A reload is used to install a software update into the module and is
not part of normal operation. When the Restart pushbutton is pressed, all LEDs go out. After
approximately 5 seconds have elapsed, the STAT LED (bottom LED) comes ON, to indicate that
the Ethernet Interface will request a reload. After the Restart pushbutton is released, the three
Ethernet LEDs flash ON, then power-up diagnostics run, and the Ethernet Interface waits for the
software load with the three Ethernet LEDs blinking in unison.
Pressing and holding the Restart pushbutton until the
Notes
Reloading the Ethernet Interface requires the attachment of the PC Software
Loader to the RS-232, RJ-11 port and initiating a load with the PC Software
Loader. The PC Software Loader is a separate software utility that updates the
communications software in the Ethernet Interface. This utility is supplied with
any updates to the Ethernet Interface software. See Appendix C, “Upgrading
the Ethernet Interface Firmware”, for more information.
At any time before you initiate a load with the PC Software Loader when the
Ethernet Interface is in the Software Load State, you can restart the Ethernet
Interface by pressing the Restart pushbutton. Pressing this pushbutton will
immediately cause the board to restart. If the reload has been initiated, see
Appendix C, “Upgrading the Ethernet Interface Firmware”, for more
information.
Restart and Enter Maintenance State:
bottom two LEDs turn ON (approximately 10 seconds) forces a restart and requests entrance to
the Maintenance state. Maintenance state must be invoked to change Advanced Parameters.
While in Maintenance state, all Advanced Parameters revert to their default value. When the
Restart pushbutton is pressed, all LEDs go out. After approximately 5 seconds, the STAT LED
comes ON, then after approximately a total of 10 seconds have elapsed, the LAN LED also comes
ON, to indicate that the Ethernet Interface will request entry to the Maintenance state. After the
Restart pushbutton is released, the three Ethernet LEDs flash ON then power-up diagnostics run
and the Ethernet Interface enters the Maintenance state.
Pressing and holding the Restart pushbutton until the
Notes
In any case, any data being transferred by the Ethernet Interface at the time of
the Restart will be lost.
The Restart pushbutton is not operable during the diagnostic phase of power-up.
The Ethernet Interface is in diagnostic phase when the EOK LED is

Ports on the CPU364
RS-232, RJ-11 Port (Station Manager Port)
The Station Manager port uses a 6-pin, RJ-11 “phone jack” connector. This port is used to
connect a terminal or terminal emulator to access the Station Manager software on the Ethernet
Interface. It is also used to connect to the PC Software Loader in case the communications
software in the Ethernet Interface needs to be updated. An IC693CBL316 cable (or equivalent) is
needed to connect the terminal, emulator, or Software Loader to the Ethernet Interface (see
Appendix B, “Communications Ports Characteristics”). On earlier versions of the CPU364
module, this port was labeled “Port 1 RS-232.”
Ethernet Ports
There are two Ethernet ports on the CPU364. Only one port can be used at a time. The Ethernet
Interface automatically detects the Ethernet port in use; special configuration is not required.
AAUI (Transceiver) Port
The 14-pin AAUI port provides the electrical and mechanical interface to a user-provided IEEE
802.3 transceiver cable, which connects the AAUI Port to an external Ethernet-compatible
transceiver (see Appendix B, “Communications Ports Characteristics”, for the characteristics of
the AAUI Port and suggested transceivers). The external transceiver is directly connected to the
Ethernet cable.
2
Caution
Do not connect or disconnect a transceiver cable to the AAUI port while
power is applied to the PLC. This may blow the AAUI port fuse and/or
cause permanent damage to the Ethernet Interface.
10Base-T, RJ-45 Port
This 8-pin, RJ-45 port provides a direct connection to a 10Base-T (twisted pair) Ethernet network
without an external transceiver.

The Series 90-30 CPU374 has several user-accessible elements (only the Ethernet Interface’s
applicable elements are discussed here.)
Three Ethernet LEDs are located at the top left of the module. The Ethernet Restart pushbutton is
located below the LEDs. The RS-232 serial port with the RJ-11 connector (similar to a modular
telephone connector) is used to connect to Station Manager. Below the serial port are twoRJ-45
ports, either or both of which can be used to connect to the Ethernet network..
The default station address (MAC address) label is located on the outside of the module.
LEDs
There are eight LEDs on the CPU374. Four of these LEDs: EOK, LAN, STAT, and PS PORT
give module status information. Four LEDS are associated with the two RJ-45 ports. The PS
(Power Supply) PORT LED is not Ethernet related; it indicates the presence of serial traffic
through the serial port of the PLC’s power supply. Each of the three Ethernet LEDs (EOK, LAN,
and STAT) can be ON, OFF, BLINKING slow, or BLINKING fast. They indicate the state of the
Ethernet Interface, traffic at the Ethernet Interface (LAN LED), and that an exception event has
occurred.
2-30 TCP/IP Ethernet Communications for the Series 90™ PLC User's Manual – May 2002 GFK-1541B
The seven Ethernet LEDs are briefly turned ON whenever a restart is performed in the
Operational state by pressing and releasing the Restart pushbutton (described below). This allows
you to verify that the Ethernet LEDs are operational.
Each RJ-45 port has two green LED indicators on it. The upper indicator, labeled LINK/ACT,
lights when the link is physically present and blinks when traffic is detected on the port. Traffic at
the port does not necessarily mean that traffic is present at the Ethernet Interface, because the
traffic can be going between the two ports of the switch. The lower indicator, labeled 100MBPS,
lights if the network connection is 100Mbps.
See “Verifying Proper Power-Up of the Ethernet Interface” for more LED information.
Ethernet Restart Pushbutton
The Ethernet Restart pushbutton serves two functions: LED test and Restart. These functions
behave similarly in all states.
Pressing the Ethernet Restart pushbutton will disrupt Ethernet communications (including any
communications to other devices attached to the embedded switch).
2
LED Test:
ON. The operator should visually verify that the LEDs go OFF and then ON at this time. Then
the Interface performs a restart.
Restart:
When the Restart pushbutton is pressed, the seven Ethernet LEDs go out then flash ON, then
power-up diagnostics run, and the software on the Interface is restarted into the Operational state.
Any time the Ethernet Restart pushbutton is pressed, the seven Ethernet LEDs flash
Pressing the Ethernet Restart pushbutton requests a restart of the Ethernet Interface.
Ports on the CPU374
RS-232, RJ-11 Port (Station Manager Port)
The RS-232, 6-pin, RJ-11 “phone jack” port is used to connect a terminal or terminal emulator to
access the Station Manager software on the Ethernet Interface. A cable is needed to connect the
terminal, emulator, or Software Loader to the Ethernet Interface (see Appendix B,
“Communications Ports Characteristics”).
Ethernet Ports
There are two RJ-45 Ethernet ports on the Ethernet Interface. Either or both of these ports may be
attached to other Ethernet devices. Each port automatically senses the data rate (10Mbps or
100Mbps), duplex (half duplex or full duplex), and cabling arrangement (straight through or
crossover) of the attached link.
Caution
The two ports on the Ethernet Interface must not be connected, directly or
indirectly to the same device. The hub or switch connections in an Ethernet
network must form a tree, otherwise duplication of packets may result.

Advanced User Parameters
Advanced User Parameters may be set for the Ethernet Interface by creating an AUP file and
putting it into the folder for the PLC application.
The AUP file is a text file, created by any convenient text editor. The file name must be
"AUP_0_1.APF". The first line of the file must consist only of the text: "AUP_0_1". Subsequent
lines in the file many contain assignments for Advanced User Parameter values using the syntax:
<parameter name>=value
There should be no space between the parameter name and the equal or between the equal and the
value. Parameter names are the same as described in GFK-1186,

Parameter values are converted to lowercase unless enclosed in a pair of double quotes; the
parameter value data depends on the parameter. Numeric parameters are entered in decimal or
hexadecimal format; hexadecimal values must be terminated with an 'h' or 'H' character. IP
address parameters must be entered in standard dotted decimal format. Character string values are
case-sensitive; as with Station Manager commands uppercase parameter values must be enclosed
within a pair of double quotes.

The semicolon character delimits comments; all characters in the line following a semicolon are
ignored. An entire line may be ignored by inserting a semicolon as the first character in the line. A
blank line is also ignored.
Caution
The IEEE 802.3 standard strongly discourages the manal configuration of
duplex mode for a port (as would be possible using Advanced User
Parameters.) Before manually configuring duplex mode for a port using
AUP, be sure that you know the characteristics of the link partner and are
aware of the consequences of your selection. In the words of the IEEE
standard: "Connecting incompatible DTE/MAU combinations such as full
duplex mode DTE to a half duplex MAU, or a full-duplex station (DTE or
MAU) to a repeater or other half duplex network, can lead to severe
network performance degradation, increased collisions, ate collisions, CRC
errors, and undetected data corruption."
Note
If speed and duplex mode of a port is forced using AUP, the switch will no
longer perform automatic cable detection. This means that if you have the
switch port connected to a switch or hub port you must use a crossover
cable. If you have the switch port connected to the uplink port on a switch
or hub or if you have the switch port connected to another Ethernet device
you must use a normal cable.
An example AUP file for the CPU374 to set the IP "Time to Live (TTL)" parameter to the value 5
is shown below. This text would appear in a file named "AUP_0_1.AUP" in the directory of the
folder for the PLC:

The CMM742 has several user-accessible elements.
Four LEDs are located at the top of the board. The Restart pushbutton is located immediately
below the LEDs. The RS-232 serial port with the RJ-11 connector (similar to a modular
telephone connector) is the Station Manager port. The RS-485 serial port with the 15-pin “D”
connector located immediately below the Station Manager port is the module’s Software Loader
port. Below these there are three ports, any one of which can be used to connect to the Ethernet
network: the 10Base-T, RJ-45 port, the AUI port, and the 10Base2, BNC port.
LEDs
There are four LEDs on the Ethernet Interface: MODULE OK, LAN ONLINE, SERIAL
ACTIVE, and STATUS. Each of these LEDs can be ON, OFF, BLINKING slow, or BLINKING
fast. They indicate the state of the Interface, traffic on the network port (LAN ONLINE LED),
and that an exception event has occurred.
GFK-1541B Chapter 2 Installation 2-41
2
All LEDs are briefly turned ON whenever a restart is performed in the Operational state by
pressing and releasing the Restart pushbutton (described below). This allows you to verify that all
LEDs are operational.
See “Verifying Proper Power-Up of the Ethernet Interface” for more LED information.
Ethernet Restart Pushbutton
The Restart pushbutton serves four functions: LED test, Restart, Restart and enter Software Load
state, and Restart and enter Maintenance state. These four functions behave similarly in all states
except for the Software Load state. While in this state, pressing the pushbutton will cause an
immediate restart into the Operational state (without performing the LED test) if the software in
the Ethernet Interface has not been corrupted or erased. If the software has been corrupted or
erased, pressing the pushbutton will cause an immediate restart back into the Software Load state.
The following text describes Restart pushbutton behavior while not in the Software Load state.
Pressing the Restart pushbutton will disrupt Ethernet communications.
LED Test:
visually verify that all the LEDs go OFF and then ON at this time. Then the Interface performs
either a restart, a restart and enter Software Load state, or a restart and enter Maintenance state,
depending on the duration that you press the pushbutton.
Restart:
the Ethernet Interface. When the Restart pushbutton is pressed, all LEDs go out. When it is
released, all LEDs flash ON, then power-up diagnostics run, and the software on the Interface is
restarted into the Operational state.
Restart and Enter Software Load State:
bottom LED (STATUS) turns ON (between 5 and 10 seconds) forces a restart and requests
entrance to the Software Load state. A reload is used to install a software update into the module
and is not part of normal operation. When the Restart pushbutton is pressed, all LEDs go out.
After approximately 5 seconds have elapsed, the STATUS LED (bottom LED) comes ON, to
indicate that the Ethernet Interface will request a reload. After the Restart pushbutton is released,
all LEDs flash ON, then power-up diagnostics run, and the Ethernet Interface waits for the
software load with all LEDs blinking in unison.
Any time the Restart pushbutton is released
Pressing the Restart pushbutton momentarily (less than 5 seconds) requests a restart of
Pressing and holding the Restart pushbutton until the
the LEDs flash ON. You should
all
Note
Reloading the Ethernet Interface requires the attachment of the PC Software
Loader to the Software Loader port and initiating a load with the PC Software
Loader. The PC Software Loader is a separate software utility that updates the
communications software in the Ethernet Interface. This utility is supplied with
any updates to the Ethernet Interface software. See Appendix C, “Upgrading
the Ethernet Interface Firmware”, for more information.
Note
At any time before you initiate a load with the PC Software Loader when the
Ethernet Interface is in the Software Load state, you can restart the Ethernet
Interface by pressing the Restart pushbutton. Pressing this pushbutton will
immediately cause the board to restart. If the reload has been initiated, see
Appendix C, “Upgrading the Ethernet Interface Firmware”, for more
information.
2-42 TCP/IP Ethernet Communications for the Series 90™ PLC User's Manual – May 2002 GFK-1541B

Restart and Enter Maintenance State:
bottom two LEDs turn ON (approximately 10 seconds) forces a restart and requests entrance to
the Maintenance state. Maintenance state must be invoked to change Advanced Parameters.
While in Maintenance state, all Advanced Parameters revert to their default value. When the
Restart pushbutton is pressed, all LEDs go out. After approximately 5 seconds, the STATUS
LED comes ON, then after approximately a total of 10 seconds have elapsed, the SERIAL
ACTIVE LED also comes ON, to indicate that the Ethernet Interface will request entry to the
Maintenance state. After the Restart pushbutton is released, all LEDs flash ON then power-up
diagnostics run and the Ethernet Interface enters the Maintenance state.
Pressing and holding the Restart pushbutton until the
Notes
In any case, any data being transferred by the Ethernet Interface at the time of
the Restart will be lost.
The Restart pushbutton is not operable during the diagnostic phase of power-up.
The Ethernet Interface is in diagnostic phase when the MODULE OK LED is
BLINKING fast and other LEDs are OFF.
Service Option Connector
If a problem occurs with the Ethernet Interface that requires continuous removal of power from
the rack or its removal from the rack, the on-board log event data will automatically be preserved
for 2–3 days. The service option connector allows you to attach a standard battery
(IC697ACC701) to save the log event data for longer periods.
Ports on the CMM742
There are two serial ports on the Ethernet Interface: the Station Manager port (RS-232) and the
Software Loader port (RS-485).
RS-232, RJ-11 Port (Station Manager Port)
The RS-232, 6-pin, RJ-11 “phone jack”, port is used to connect a terminal or terminal emulator to
access the Station Manager software on the Ethernet Interface. A cable is needed to connect the
terminal or emulator to the Ethernet Interface (see Appendix B, “Communications Ports
Characteristics”).
RS-485, D-Type Port (Software Loader Port)
The RS-485, 15-pin, D-type port is used to connect to the PC Software Loader in case the
communications software in the Ethernet Interface needs to be updated. The characteristics of
this port are given in Appendix B, “Communications Ports Characteristics”.
GFK-1541B Chapter 2 Installation 2-43

Ethernet Ports
There are three Ethernet ports on the Ethernet Interface. Only one Ethernet port may be used at a
time. The Ethernet Interface automatically detects the Ethernet port in use; special configuration
is not required. (See also the topic “Disable Onboard 10Base2 Port Jumper” below.)
Caution
Do not connect or disconnect a transceiver or network cable to the AUI or
BNC ports while power is applied to the PLC. This may blow the port fuse
and/or cause permanent damage to the Ethernet Interface.
10BaseT Port
This 8-pin, RJ-45 port provides a direct connection to a 10Base-T (twisted pair) Ethernet network
without an external transceiver.
AUI Port
This 15-pin, D-type AUI port with slide-lock provides the electrical and mechanical interface to
the user-provided IEEE 802.3 transceiver cable, which connects the AUI Port to an external
Ethernet compatible transceiver (see Appendix B, “Communications Ports Characteristics”, for
the characteristics of the AUI port). The external transceiver is directly connected to the Ethernet
cable.
10Base2, BNC Port
This BNC port provides a direct connection to a 10Base2 (thin wire) Ethernet network without an
external transceiver.

COMMREQ Function Block
The COMMREQ Function Block is the ladder instruction that triggers the execution of the
Channel command. In the COMMREQ Function Block, you specify the rack and slot location of
the Ethernet Interface, a task value, and the address of a location in memory that contains the
Command Block. There is also a fault output on the COMMREQ Function Block that indicates
certain programming errors.
COMMREQ Command Block
The COMMREQ Command Block is a structure that contains information about the Channel
command to be executed. The Command Block consists of two parts:
Common Area - includes the address of the COMMREQ Status word (CRS word).
Data Block Area - describes the Channel command to be executed.
When the COMMREQ function is initiated, the Command Block is transferred to the Ethernet
Interface for action.
SRTP Channel Commands
The Channel commands are a set of client PLC commands used to communicate with a server
PLC.

Advantages of Channel Commands
The advantage of Channel commands is their ability to establish a channel to execute multiple

Up to 32 channels (numbered 1–32) can be established by a Series 90-70 Ethernet Interface.
Up to 16 channels (numbered 1–16) can be established by a Series 90-30 Ethernet Interface.
(If the Series 90-30 Ethernet Interface supports Modbus/TCP Channels, the 16 available
channels are shared between SRTP and Modbus/TCP.)

Status Data
There are several types of status data available to the client PLC logic program.
LAN Interface Status Bits (LIS Bits):
location of this 80-bit status area is assigned using the Configuration software in the “Status
Address” field. The LIS bits contain information on the status of the Local Area Network (LAN)
and the Ethernet Interface itself.
Channel Status Bits:

each of the channels that can be established (32 channels for the Series 90-70 Ethernet Interface, 16
channels for the Series 90-30 Ethernet Interfaces). Status bits for unused channels are always set to
zero.
The Channel Status bits comprise bits 17–80 (64 bits) of the 80-bit status

The Logic Program Controlling Execution of the COMMREQ Function Block
Care must be taken in developing the logic that controls the execution of the COMMREQ function.
The COMMREQ function must be initiated by a one-shot to prevent the COMMREQ from being
executed repeatedly each CPU scan, as this will overrun the capability of the Ethernet Interface and
possibly require a manual restart. Checking certain status bits before initiating a COMMREQ
function is also important. In particular, the LAN Interface OK bit should be used as an interlock to
prevent execution of the COMMREQ function when the Ethernet Interface is not operational.
Following initiation of a COMMREQ on a channel, no further COMMREQs should be issued to
that channel until a non-zero CRS word has been returned to the program from the Ethernet
Interface.

The Ethernet Interface also transfers data to a
running Host Communications Toolkit (HCT) software. There is one channel command for
transferring data to a host computer:
Send Information Report
These Channel commands are based on the concept of periodic data transfers. The client (local)
PLC uses a single COMMREQ function to establish a channel (connection) to a server (remote)
PLC and to request that specific data be periodically transferred between the PLCs.
Note: For this discussion of the Command Blocks, assume that the operator/programmer is

Aborting and Re-tasking a Channel
There are four ways a channel can be aborted:
1. When the PLC CPU is stopped, all channels in use are aborted automatically.
2. A channel (or all channels) can be aborted by issuing an Abort Channel command.
3. A channel in use can be re-tasked by issuing an establish command for its channel number.
This aborts the previous channel operation and then performs the new channel operation.
4. A channel is also automatically aborted if a fatal error occurs.
Retrieving Detailed Status on the Channel
local
There are several forms of status available to the ladder program. One form of status is obtained
through the Retrieve Detailed Channel Status (RDCS) command described later in this section.
Specifying a Network Address
All establish commands must identify the remote server device with which data will be
transferred. The remote device may be specified in two ways: By IP address, or by a name
previously defined with the proper IP address. Examples of each Network Address type are
provided for all establish commands. (For further information on the use of Network Address
names, see the chapter: “Network Administration Support”.)
GFK-1541B Chapter 3 Programming Channel Commands 3-9

Establish Read Channel (2003)
The Establish Read Channel command requests that a channel be associated with a remote PLC
and that data from the remote PLC be transferred (periodically) to the local PLC. The Command
Block specifies the period, the number of reads from the server (remote PLC) to perform, and the
timeout allowed in waiting for each transfer to complete. The first read is performed
immediately, regardless of the period specified.
Example 1 Command Block–Basic Example
Establish a channel (Channel 5) to a remote PLC at IP address 10.0.0.1. Return the COMMREQ
Status word to %R10. Read remote PLC registers %R50–%R57 to local PLC registers %R100–
%R107. Repeat the read 10 times, once every 7 seconds, with a timeout of 500 ms for each read.

(Word 12) Timeout for Each Read:
Word 12 specifies the time (in hundredths of a second) the
Ethernet Interface will wait for a read transfer to complete before setting the Channel Error bit
and Detailed Channel Status words to indicate a non-fatal timeout error. The transfer can still
complete even after a timeout occurs. As a result, an application can choose what to do if one
occurs. If the timeout value is specified as zero, no timeout errors will be reported.
For most applications a timeout need not be specified because the read period, in effect, acts as a
timeout. (Word 12 should be zero for no timeout). However, there are two special
circumstances in which specifying a timeout is recommended:
When the number of time units (Word 11) is zero, so that a subsequent transfer will be issued
as soon as the previous transfer completes and no period errors are reported. In this case a
timeout value can be specified so that timeout errors will be reported by the Channel Error
bit.
When the read period is very long (minutes or hours). In this case a shorter timeout value
can be specified so the application doesn’t have to wait for the read period to expire before
taking action.

complete even after a timeout occurs. As a result, an application can choose what to do if one
occurs. If the timeout value is specified as zero, no timeout errors will be reported.
For most applications a timeout need not be specified because the write period, in effect, acts as a
timeout. (Word 12 should be zero for no timeout.) However, there are two special
circumstances in which specifying a timeout is recommended:
When the number of time units (Word 11) is zero, so that a subsequent transfer will be issued
as soon as the previous transfer completes and no period errors are reported. In this case a
timeout value can be specified so that timeout errors will be reported by the Channel Error
bit.
When the write period is very long (minutes or hours). In this case a shorter timeout value
can be specified so the application doesn’t have to wait for the write period to expire before
taking action.

The Send Information Report COMMREQ requests that a particular block of memory within the
PLC CPU reference tables be transferred periodically from an Ethernet Interface (SRTP Client) to
a Host Application SRTP Server. The Command Block specifies the repetition period, the
number of transfers to the server to perform, and the timeout allowed in waiting for each transfer
to complete. The first send is performed immediately, regardless of the period specified.

Address name of the remote host as an ASCII character string. The Network Address name may
contain up to 31 characters, is case sensitive, and must be terminated with a null character (zero).
An error will result if the Network Address name is empty or if the name could not be resolved
into the address of an actual device.
The Network Address name must have each pair of ASCII characters reversed within the PLC
memory. For example, the name “PLC_1aa” (“P” = 50H, “L” = 4CH, “C” = 43H, “_” = 5FH,
“1” = 31H, “a” = 61H, “a” = 61H ) would have 4C50H in Word 20, 5F43H in Word 21, 6131H in
Word 22, and 0061H in Word 23. Words 24–35 all contain 0000H.

Abort Channel (2001)
The Abort Channel command immediately disconnects an active channel from its remote PLC
and renders the channel idle. The Channel Transfer bit, the Channel Error bit, and the Detailed
Channel Status words for the channel are set to zero.

(Word 7) Channel Command Number:
This command parameter requests that a channel be
aborted. If the command is processed successfully, it will terminate the processing on the channel
by the time success is indicated in the COMMREQ Status word.
(Word 8) Channel Number:
The channel number specifies the channel to be disconnected (1–32
for Series 90-70 PLCs and 1–16 for Series 90-30 PLCs). As a convenient way to abort all
channels, if the channel number parameter is –1 (FFFFH), all channels in use will be aborted. It
is
an error to abort all channels when there are none in use. Neither is it an error to abort an
not
idle channel.
Note
For the Abort Channel and Retrieve Detailed Channel Status commands, no
actual data is transmitted on the network. Communication occurs between the
client PLC CPU and the local Ethernet Interface only. For these commands, the
actual function is performed locally within the Ethernet Interface and then the
COMMREQ Status word is sent immediately to the CPU.

Retrieve Detailed Channel Status (2002)
3
The Retrieve Detailed Channel Status command requests that the
words be returned for a channel. The Detailed Channel Status words contain an active/inactive
channel indicator and the last channel error codes seen. These two words of detailed status
supplement the information available in the COMMREQ Status word and the Channel Status bits.
The command has no effect on the value of the Channel Status bits.
Be aware that the Detailed Channel Status words are updated every time the status of the channel
changes. If, for example, the channel is operating with a fast repetition period, the status words
may change faster than the ladder executes the COMMREQ to retrieve them. Therefore, some
status values might be missed from the ladder’s point of view.

Status Data
This section describes all the status data that is available to the ladder program to determine the
state of the Ethernet Interface and its channels.
Types of Status Data
There are four main types of status data available to your ladder program:
OK Output of the COMMREQ Function Block. (Series 90-70 PLCs only)
1.
if the PLC CPU was successful in transferring the COMMREQ data from the reference table
memory specified by the COMMREQ function block into the memory local to the Ethernet
Interface. This does not indicate that the Ethernet Interface has processed the COMMREQ,
only that it has been received by the Ethernet Interface.
Barring ladder programming errors, the OK and FT outputs should not both be set in the
same scan by the same COMMREQ.
This output is set

FT Output of the COMMREQ Function Block.
2.
error in the COMMREQ Function Block itself, if the rack and slot specified in the
COMMREQ SYSID parameter is not configured to contain an Ethernet Interface, or if the
data block length specified in the Command Block is out of range. This output also may
indicate that no more COMMREQ functions can be initiated in the ladder program until the
Ethernet Interface has time to process some of the pending COMMREQ functions.
If the FT Output is set, the CPU does not transfer the Command Block to the Ethernet
Interface. In this case, the other status indicators are not updated for this COMMREQ.
Status Bits.
3.
Interface. These bits are generally used to prevent initiation of a COMMREQ function when
certain errors occur or to signal a problem on an established channel. The status bits include
the LAN Interface Status bits and the Channel Status bits. The starting location of these bits
is user-configurable.
The LAN Interface Status bits monitor the health of the Ethernet Interface itself, such as the
LAN Interface OK bit and the AUI/BNC Fuse Blown bit for Series 90-70 PLCs (AAUI Fuse
Blown bit for Series 90-30 PLCs). The Channel Status bits monitor the health and progress
of a channel established using the Establish Read/Write Channel commands.
Communications Status Words.
4.
information: The COMMREQ Status word (CRS word) and the Detailed Channel Status
words (DCS words). The communications status words are not updated in the CPU each
scan as are the status bits. They are generally used to determine the
communications error after the COMMREQ function is initiated. The cause is reported in
the form of an error code described later in this section.
The status bits are updated in the CPU once each PLC scan by the Ethernet

GFK-1541B Chapter 3 Programming Channel Commands 3-31
3
The COMMREQ Status word (CRS word) is returned from the Ethernet Interface to the PLC
CPU immediately if the Command Block contains a syntax error or if the command is local.
For remote commands with no syntax error, it is returned either after the channel is
established successfully and the first transfer has completed or if there is an error establishing
the channel. The location of the CRS word is defined in the Command Block for the
COMMREQ function.
The Detailed Channel Status words (DCS words) are returned from the Ethernet Interface to
the CPU only by executing the Retrieve Detailed Channel Status Command. If a channel
error is indicated (by the Channel Error bit) after the channel is established, the first word of
the DCS words will contain an error code indicating the cause of the error. The second word
of the DCS words indicates whether the channel is active or idle.
Be aware that the Detailed Channel Status words are updated every time the status of the
channel changes. If, for example, the channel is operating with a fast repetition period, the
status words may change faster than the ladder executes the COMMREQ to retrieve them.
Therefore, some status values may be missed from the ladder’s point of view.
Description of the Status Data
The errors and status reported in each type of status data are described below.
OK Output of the COMMREQ Function Block (Series 90-70 PLCs Only)
The OK output is set if the PLC CPU has successfully delivered the COMMREQ to the Ethernet
Interface.
FT Output of the COMMREQ Function Block
The FT Output passes power upon the following errors:
Invalid rack/slot specified. The module at this rack/slot is unable to receive a COMMREQ.
Invalid Task ID.
Invalid Data Block length (zero or greater than 128).
Too many simultaneous active COMMREQs (overloading either the PLC CPU or the
Ethernet Interface).
3-32 TCP/IP Ethernet Communications for the Series 90™ PLC User's Manual – May 2002 GFK-1541B
LAN Interface Status (LIS) Bits
The status bits normally occupy a single block of memory. The location of this block is specified
during configuration of the Ethernet Interface. The first 16 bits of the block (see Table 5-3) are
the LAN Interface Status (LIS) bits. The next 64 bits are the Channel Status bits (2 for each
channel).
