Ethernet Interface Module
The Ethernet Interface Module, IC695ETM001, connects a
PACSystems RX3i controller to an Ethernet network. It enables
the RX3i controller to communicate with other PACSystems
equipment and with Series 90 and VersaMax controllers. The
Ethernet Interface provides Transmission Control Protocol and
Internet Protocol (TCP/IP) communications with other control
systems, host computers running the Host Communications
Toolkit or programmer software, and computers running the
TCP/IP version of the programming software. These
communications use the Service Request Transport Protocol
(SRTP), Modbus TCP, and Ethernet Global Data (EGD) protocols
over a four-layer TCP/IP (Internet) stack.
Features of the RX3i Ethernet Interface include:
▪
Full programming and configuration services. Firmware
upgrades from the RX3i CPU using the WinLoader
software utility, which is supplied with updates to the
Ethernet Interface software.
▪
▪
Periodic data exchange using Ethernet Global Data (EGD).
▪
▪
TCP/IP communication services using SRTP.
▪
Built-in Station Manager for on-line supervisory access to
the Ethernet Interface. Dedicated Station Manager port.
▪
Two auto-sensing 10Base T / 100Base TX RJ-45 shielded
twisted-pair Ethernet ports for direct connection to either
a 10BaseT or 100BaseTX IEEE 802.3 network without an external transceiver. There is only one interface to the
network (only one Ethernet MAC address and only one IP address).
▪
▪
Internal network switch with Auto negotiate, Sense, Speed, and crossover detection.
EGD Commands to read and write controller and EGD
exchange memory over the network.
Support for SRTP Channels, Modbus/TCP Server, and
Modbus/TCP Client
Recessed Ethernet Restart pushbutton permits manually restarting the Ethernet firmware without power cycling
the system.
▪
▪
LEDs: Ethernet OK, LAN OK, Log Empty, individual port activity and speed LEDs.
▪
Time synchronization to SNTP Time Server on Ethernet network (when used with Release 5.00 or later CPU
module).
Configurable stand-alone Redundant IP addressing, which allows a single IP address to be assigned to
corresponding Ethernet modules in two different controllers. The Redundant IP address is configured in
addition to the normal unique IP address of each Ethernet module. Under application logic control, only the
Ethernet module in the active unit can use the Redundant IP address.

SRTP and EGD
performance differs
from Series 90*-30
SRTP and EGD performance in the RX3i differs slightly from the Series 90-30. Each
RX3i Ethernet Interface supports a greater number of SRTP connections and EGD
exchanges.
The RX3i currently has several SRTP and EGD operational restrictions compared
to the Series 90-30. When migrating Series 90-30 Ethernet applications to the
RX3i, please carefully read the Ethernet Operational Notes.
Series 90-30 LAN
Interface module
(IC693CMM321) not
supported by RX3i
The Series 90-30 LAN Interface Module (IC693CMM321) is not supported by the
RX3i and should not be placed in an RX3i rack. (Series 90-30 CPUs with
embedded LAN Interface, IC693CPU364 and IC693CPU374, like any Series 90-30
CPU, should not be placed in an RX3i rack.)
Modbus/TCP support
Release 3.60 of the PACSystems Ethernet Interface adds Modbus/TCP Client
Channels capability. It supports Modbus Conformance Class 0 function codes 3
and 16, Conformance Class 1 function codes 1, 2, 4, 5, 6, and 7, and Conformance
Class 2 function codes 15, 22, 23, and 24. PACSystems Ethernet supports 32
client connections shared between all client protocols. For example, if 16 client
connections are used for SRTP channels, there are 16 client connections available
for Modbus/TCP channels. Any given channel can be assigned to only one
protocol at a time.

Description
Number of SRTP requests
tallied may vary
When running multiple SRTP client channels, the number of requests, as
reported by the client and the server, may differ between the connections.
SRTP connections remain open
after IP address changed
The Ethernet Interface does not terminate all open SRTP connections
before changing its IP address. If the local IP address has changed, any
existing open TCP connections are unable to normally terminate. This can
leave SRTP connections open until their underlying TCP connections time
out. If quicker recovery of the SRTP connection is needed, modify the
“wkal_idle” Advanced User Parameter to reduce the TCP keep-alive timer
to the desired maximum time for holding open the broken connection.
Refer to TCP/IP Ethernet Communications for PACSystems, GFK-2224, for
details.
REPP does not save results of
aborted PING
The Station Manager REPP command does not retain the results of a PING
that is aborted due to error. Results are reported when the PING is
aborted, but subsequent REPP commands give the results of the last
successfully terminated PING.
Multiple log events
The Ethernet Interface sometimes generates multiple exception log events
and Controller Fault Table entries when a single error condition occurs.
Under repetitive error conditions, the exception log and/or Controller Fault
Table can be completely filled with repetitive error messages.
Intermittent SNTP loss of
synchronization
Under moderately heavy EGD traffic load, the Ethernet Interface may
occasionally lose synchronization with its SNTP time server and generate
exception log event 29, entry 2=bH.
SRTP communication delays
Average latency of communications on SRTP channels may vary
considerably due to TCP retransmissions. SRTP client applications should
be designed to take this variance into account. In particular, SRTP client
applications migrating from Series 90 SRTP servers to PACSystems may
need to lengthen SRTP timeout parameters.
Spurious ‘Ethernet Failure’
error
On rare occasions, the error “Module hardware fault” may be reported on
the Ethernet daughterboard. The corresponding fault in the exception log
is Event = 1, followed by text "Ethernet failure". This fault is a nuisance fault
and may be ignored.
Spurious Ethernet fault
In rare instances, after power cycle, the Ethernet Interface may log the
following fault, Event = 28H, Entry 2 = 000eH. This fault can be safely
ignored.
Unexpected EGD COMMREQ
status
EGD Commands may return COMMREQ Status 9590H (= internal error)
instead of the expected B190H (= Can’t locate remote node) when unable
to locate a remote device on the network.

Description
Very heavy EGD production/
consumption at server may
cause EGD command timeouts
Very heavy EGD production and/or consumption at a server device may
cause EGD command timeout errors when another device attempts to
send EGD commands to that server. If EGD commands must preempt
normal production, you may set the “gcmd_pri” Advanced User Parameter
to 2 (see GFK-2224, Appendix A). Note that by doing so, EGD exchange
production may be delayed.
SRTP server errors can cause
timeouts at channel client
The SRTP Server in the PACSystems Ethernet Interface can encounter
various errors if a remote Series 90 client takes down an SRTP connection
and then establishes a new connection. This can cause unexpected
channel timeout errors 0190H or 0290H at the client. The SRTP server
errors in the Ethernet exception log are identified as Event = 2; Entry 2 may
be 001cH, or 0021H.
When an EGD Command attempts a write operation to a bit-mode
reference memory range (%I, %Q; %T, %M, %SA, %SB, %SC) where the
amount of data to be written exceeds the configured size of that
reference memory, the command will return failure status but partial data
may be written into the reference memory. The amount of partial data
written depends upon the starting bit memory location and the data
length as follows:
▪ If data starts on a byte boundary (location = (8  n) + 1), no partial data
is written.
▪ If data does not start on a byte boundary (location = (8n)+1) and data
exceeds the configured reference memory by 8 or more bits, partial
data is written from the starting location to the next byte boundary
after the starting location.
▪ If data does not start on a byte boundary (location = (8n)+1) and data
exceeds the configured reference memory by less than 8 bits, partial
data is written from the stating location to the end of configured
reference memory.
For a Write PLC Memory command, this can occur when writing data into
the target PLC. For Read PLC Memory or Read Exchange commands, this
can occur when writing data received from the target controller into the
local CPU memory. The logic application must not use any data returned
to the local CPU if the EGD command status indicates failure.
To avoid writing partial data to the local or remote PLC, be sure bit
memory data transfers do not exceed the configured reference memory
sizes at the appropriate PLC.
EGD command range failure
can write partial data to
controller bit memory
Do not operate with CPU in
incorrect slot
The operation of the Ethernet interface is disrupted if the RX3i CPU is
placed in a slot other than the one in which it is configured. Various
Ethernet exception log events may occur, such as (Entry = 2, Entry 2 = 30
or 35 or 39 or 1e or 1f) or (Entry = 8, Entry 2 = b).
No CPU fault logged when
Ethernet interface in fatal blink
code
The CPU does not log any Controller or I/O Faults when the Ethernet
Interface has a fatal blink code. The application should monitor the LAN
interface OK status bit to detect loss of module.
EGD I/O has unexpected
variability under heavy load
EGD I/O has intermittent unexpected variability under heavy load. For a
Produced Exchange, EGD samples may occasionally be delayed by as
much as a production period or more.
Clear of large hardware
configurations may cause log
event 08/20
A Log event 08/20 may occur when very large hardware configurations
are cleared and transfers are active on other Server connections. This log
event can be safely ignored.

Description
Reset pushbutton
Reset pushbutton action is different from other PACSystems Ethernet
products. On the RX3i Ethernet module, the state of the pushbutton when
the module powers up can change the behavior of the Restart
pushbutton. Under normal operation, a pushbutton press produces a
rising-edge signal that triggers a module restart. However, if the
pushbutton is pressed when power is activated (either by pressing the
pushbutton before turning power on or by continuing to hold the
pushbutton in after a restart), the functionality of the pushbutton is
inverted. When the pushbutton is later released, an "incorrect" rising-edge
is detected, which triggers an inappropriate module restart. This does not
occur on other PACSystems Ethernet products.
COMMREQ Status Word value
of 0x54A0 occasionally
returned for EGD commands
Occasionally a COMMREQ Status Word value of 0x54A0 is returned after
COMMREQs for Ethernet Global Data commands when the previouslytransferred command has experienced retries in the network. Executing
the COMMREQ again results in successful transfer of the command.
Modbus/TCP channel aborted
during power-cycle
After powering up an RX3i running Modbus/TCP client channels, the
establish connection occasionally fails because the server rejects the
"open" request from the client. The connection will then succeed if the
application retries the open when it sees a 0x9690 or 0xAA90 response to
an open request or to the first write request.
Controller response timeout
errors (8/08) in Ethernet
exception log under extremely
heavy SRTP traffic
Under extremely heavy SRTP traffic conditions, the Ethernet Interface may
log an event in the Ethernet exception log (Event 8, Entry 2 = 08H)
indicating an overload condition. This error terminates the SRTP
connection. If this event appears, either the traffic load should be
reduced, or the application should use an alternate communications
method to verify that critical data transfers were not lost due to the
overload.
SRTP channel transfers may
take up to 20 seconds after
power cycle
When SRTP communications are interrupted by a power cycle, the
Ethernet interface may require up to 20 seconds to reestablish TCP
connection used for SRTP communications.
"rmdir" Station Manager
command does not work for
multi-level directory path
The "rmdir" Station Manager command does not operate properly with a
multi-level directory path. Instead, first change to the parent directory,
then delete the target directory without specifying a path. For example,
the "rmdir dir1/dir2" results in "RMDIR Failed, dir1/dir2 does not exist".
Instead, first do "cd dir1" and then "rmdir dir2".
Intermittent Ethernet log event
8H/15H after power cycle
When starting after a power cycle, the Ethernet Interface may
intermittently log an exception (entry 8H, Entry 2 = 15H, Entry 3 = 0000H,
Entry 4 = 00aaH). This exception is benign and may be ignored.
Intermittent Modbus/TCP
Server log events when using
"killms" Station Manager
command
When using the "killms" Station Manager command to manually terminate
an active Modbus/TCP server connection, the following Modbus/TCP errors
may occur in the Ethernet exception log: Event 2fH, Entry 2 = 209H, 212H,
21bH, or 221H. These errors may be ignored.
Module intermittently
unresponsive after reset
Intermittently, when the module is restarted by using the pushbutton or
Station Manager command, the module will blink its OK LED for 5
minutes before completing the restart. After the restart is complete the
module fails to communicate with the CPU module. The remedy is to
power-cycle the PLC.

Description
A890 Commreq status after
multiple Modbus open
command attempts
When using a Commreq to open a Modbus/TCP Channel to a remote
server, if the initial Commreq returned an AA90 status, then future Open
Commands may return A890 status. This indicates that local networking
resources have been consumed and are not available for further
connection attempts. If this occurs, the application must wait at least
60 seconds before making the next connection attempt. This will allow
networking resources to be released and made available for the next
Modbus Open Command.
Modbus/TCP request packets
The Modbus/TCP server expects to receive each Modbus/TCP request in
a separate TCP packet. If multiple requests are sent in a single packet,
the server may or may not send a response to each request. If
responses are sent to the client, they will be sent in separate TCP
packets.
EGD production delayed after
RMS of EGD
When a produced EGD exchange is added or modified by a Run-mode
Store, the exchange will not be produced until one production period of
time has elapsed after the completion of the run-mode store.
Station Manager PING
commands
When initiating ICMP echo requests from the PLC via the Station
Manager’s PING command, the operation occasionally fails and an
exception is logged (Event eH, Entry 2 = 6H).
Station Manager “referr” tally
The EGD Station Manager “referr” tally may be incremented twice when
an exchange timeout occurs. Exchange status word reporting works
correctly and is not affected.
“wkal_idle” AUP parameter
should not allow zero
Zero is allowed for the “wkal_idle” (TCP keepalive timer) but it is an invalid
value.
TCP connection may timeout
early if the timeout is set
greater than 10 minutes
If the TCP connection timeout is set higher than 10 minutes, the
connection may timeout before the configured value. The connection
timeout is derived from three AUP parameters: wkal_idle + (wkal_cnt + 1) 
wkal_intvl.

Remote Station Manager
access is disabled until Station
manager password is changed
User should change the station manager password to other than the
default password. The remote station manager access is disabled until the
station manager password is changed to other than the default password.
The station manager password can be changed using an AUP file. (Refer
to Appendix A, Configuring Advanced User Parameters in TCP/IP Ethernet
Communications for PACSystems User’s Manual, GFK-2224K.)
Changing the default Station
Manager password is strongly
recommended
GE Intelligent Platforms strongly recommends that you change the Station
Manager password to a value other than the default. Before a
configuration has been stored to the CPU, you can change the password
by using the CHPARM command to modify the Advanced User parameter
(AUP) stpasswd. For details on using this command, refer to the Station
Manager Manual, GFK-2225.
It is not recommended that you change any AUP other than stpasswd.
1. Use the current password to access the Modify level of the Station
Manager. The default password is system.
2. Change the password.
Example: = chparm stpasswd newpass
3. Restart the Ethernet interface or cycle power. Changes made via the
CHPARM command do not take effect until the Ethernet interface is
restarted or power is cycled. Advanced User Parameters are saved in
non-volatile memory. Changes made by the CHPARM command are
retained over restart and power cycles, until changed again by the
CHPARM command.
4. To permanently change the Station Manager password, you must
change the stpasswd parameter in the AUP file. See the TCP/IP Ethernet
Communications for PACSystems User’s Manual, GFK-2224 for details.
(After the CPU configuration has been stored into the CPU, the CHPARM
command is prohibited and any previous changes made with it are no
longer effective.)
Configuration of IP Address is
required before using Ethernet
communications
The Ethernet Interface cannot operate on a network until a valid IP
address is configured. The Ethernet addressing information must be
configured prior to actual network operation, or to recover from
inadvertent changes to the Ethernet addressing data at the Ethernet
Interface. Use one of the following methods to initially assign an IP
address:
 Connect a serial terminal to the Interface’s Station Manager port.
Then use the CHSOSW command to enter the desired IP address. For
details, see PACSystems TCP/IP Communications Station Manager
Manual, GFK-2225.
 Temporarily assign an IP address to the module using the SetIP tool
over the Ethernet network. For details, see TCP/IP Ethernet
Communications for PACSystems, GFK-2224.
 The Ethernet Interface automatically obtains a temporary IP Address
from a BOOTP server on the network. For details, see TCP/IP Ethernet
Communications for PACSystems, GFK-2224.
Once a temporary IP address has been set up, the Ethernet Interface can
be accessed over the network (by the Machine Edition programming
software). The programmer should then be used to configure the proper IP
address for the Ethernet Interface.

Description
Default IP address (0.0.0.0)
attempts to set IP address
via BOOTP
The default IP address value (0.0.0.0), whether obtained from HW
Configuration or backup configuration, causes the Ethernet Interface to
request a temporary IP address from a BOOTP server device on the
network.
LAN must be tree, not ring
The two Ethernet network ports on the PACSystems RX3i Ethernet
Interface must not be connected, directly or indirectly, to the same
network device. The hub or switch connections in an Ethernet network
must form a tree and not a ring; otherwise duplication of packets and
network overload may result. In this situation, the RX3i Ethernet modules
will continually reset.
Reporting of duplicate IP
address
The PACSystems RX3i does not log an exception or a fault in the Controller
Fault Table when it detects a duplicate IP address on the network.
Multiple zero period EGD
exchanges may not produce
similar numbers of samples
If more than one EGD produced exchange is configured for a production
period of zero, the exchanges may not produce similar numbers of
samples. Due to the way that scheduling occurs when multiple
exchanges are scheduled “as fast as possible”, some zero period
exchanges may produce significantly more samples than others. For more
consistent EGD production, configure the produced EGD exchanges with
non-zero production periods.
Changing IP address while
SRTP connection open may
generate log events
Open SRTP Server connections established with a remote SRTP client are
not terminated as expected when the RX7i’s IP address is changed
(typically by storing a new HW Configuration to the RX7i). A Series 90 SRTP
client (“SRTP channels”) reports either a 9690H or 0190H status; the SRTP
connection may remain open until the connection is terminated as a result
of a client timeout. Please refer to Open Ethernet Problems, Internal
Problem ID Code CR-1434 for more information.
Series 90-30 datagram
restrictions
Series 90-30 – format datagrams are supported, but cannot access %P or
%L memory.
Advanced User Parameter
wsnd_buf should not be
changed
The Advanced User Parameter “wsnd_buf” should not be changed.
Changing this value may cause the LAN LED to go out and the Ethernet
Interface to drop connection.
Heavy load can block Station
Manager
As explained in PACSystems TCP/IP Station Manager Manual, GFK-2225,
Chapter 1, a heavy EGD and/or SRTP load can block Station Manager
operation.
One-time delay of EGD
Production (and possibly
Consumption) if more than 24
SRTP Server connections are
started simultaneously
If more than 24 SRTP Server connections are established simultaneously,
EGD Production may be briefly delayed for each connection after the 24th
when the connections are first made after power is applied. If EGD
consume acceleration has been disabled, then EGD Consumption is also
delayed. The delay only occurs once when the SRTP Server connection is
established for the first time after Powerup. No delay is experienced for
the first 24 SRTP Server connections.
Very heavy EGD
production/consumption at
server may cause EGD
command timeouts
Very heavy EGD production and/or consumption at a server device may
cause EGD command timeout errors when another device attempts to
send EGD commands to that server. If EGD commands must preempt
normal production, you may set the “gcmd_pri” Advanced User Parameter
to 2 (see GFK-2224, Appendix A). Note that by doing so, EGD exchange
production may be delayed.

Description
SRTP Application Timeouts
must accommodate network
connection overhead
The application timeouts within SRTP Channels also include the time
needed to establish and maintain the underlying network and STRP
connection. Examples are establishing the TCP connection for a new
channel, establishing communication with the remote device, and TCP
retransmissions during Channel operations. If the time needed for TCP
connection establishment or maintenance exceeds the user-specified
channel application timeout values, an application timeout will occur.
Channel application timeouts are temporary errors; the channel continues
to run.
Client Channels and
Redundant IP
In a Redundancy System, Client Channel COMMREQs can only be initiated
from the unit that owns the Redundant IP address. Therefore, the user
application logic should use Bit 6 in the LAN Interface Status bit area,
“Redundant IP Active” as part of their enabling logic that drives a client
channel COMMREQ.
Idle Modbus/TCP connection
between a Series 90 and a
PACSystems may be
prematurely terminated
An idle Modbus/TCP connection between a Series 90 controller and the
PACSystems Ethernet Interface may be prematurely terminated. There is
an incompatibility between the TCP "Keep-Alive" timer values on the
PACSystems Ethernet Interfaces and Series 90 Ethernet Interfaces. The
default value of the keep-alive timer for the Series 90 modules is set to a
much higher value than for the PACSystems. To keep TCP connections
open between a Series 90 Ethernet Interface and a PACSystems Ethernet
Interface, the Series 90 Interface Advanced User Parameter wkal_time
should be set to the value 750 to match that of PACSystems. With this
change, TCP connections remain open indefinitely. This also applies to
SRTP Client Channels that have infrequent traffic and can be resolved by
using the same technique.
Attempt to open 17 or more
Modbus server connections
may appear successful
If more than the maximum 16 supported Modbus Server Connections are
attempted, the TCP connection may succeed, but no data may be
subsequently transferred.
SRTP Connections Remain
Open After IP Address Changed
The Ethernet Interface does not terminate all open SRTP connections
before changing its IP address. Once the local IP address has changed,
any existing open TCP connections are unable to normally terminate. This
can leave SRTP connections open until their underlying TCP connections
time out. If quicker recovery of the SRTP connection is needed, modify the
“wkal_idle” Advanced User Parameter to reduce the TCP keep alive timer
down to the desired maximum time for holding open the broken
connection. Refer to TCP/IP Ethernet Communications for PACSystems,
GFK-2224, for details.
RX3i CPU Time Used for
Produced EGD Timestamps
Changing the Ethernet interface time via the CHTIME command does not
affect the timestamp value within EGD exchanges produced from this
Ethernet interface. The EGD timestamp value reflects the current CPU
time. In Series 90-70 products and the Series 90-30 CPU364, EGD
timestamps are taken from the Ethernet interface and do reflect CHTIME
modifications.
ENIU Stale Data During Run
Mode Store of EGD
In a large PPS system running 20 ENIUs, when a Run-mode Store is
performed that deletes the EGD exchanges for 10 of the ENIUs, the other
ENIUs will see the status on their exchanges indicate consumption
timeouts during the RMS. At the completion of the RMS, the exchanges
operate normally.
One TTL value configuration
for all EGD groups
The system accepts only one TTL value. If you configure a separate TTL
value for each EGD group, the minimum TTL value is configured for all EGD
groups.
