GFK-1085X
Restrictions and Open Issues
■
The Ethernet Interface sometimes generates multiple exception log events and PLC Fault Table
entries when a single error condition occurs. Under repetitive error conditions, the exception log
and/or PLC Fault Table can be completely filled with repetitive error messages.
■
Initialization errors that generate any of the following exception log events should also restart the
Ethernet Interface into Maintenance state: event 1b, entry 2 = 0003h, event 1c, entry 2 = 25h, or
event 1c, entry 2 = 26h. The Ethernet Interface does not restart in these conditions.
■
Use of the same IP Address by this Ethernet Interface and by another device on the same network
results in the PLC Fault Table message “Bad remote application request; discarded request.” This
condition should be identified more precisely.
■
When the client or server PLC scan time exceeds 100 ms, channels may fail with error codes 2411,
0B11, 9B90, 3F11, or 9590. The error codes may be viewed by doing a Stat H command.
■
While a local Station Manager “TRACE LZ” troubleshooting command is in effect at an Ethernet
Interface, do not issue Station Manager “REM <node> TEST” commands to it from a remote
Interface. Doing so can cause errant behavior, including Interface lockup and loss-of-module in the
PLC fault table.
■
After performing a firmware update to an Ethernet Interface in which one or more Advanced User
Parameters have been set to non-default values, the PLC Fault Table does not contain the message
it should (“LAN IF can’t init-check parms; running soft Sw Utl”); rather, no fault table entry appears.
There is no indication in the fault table that the Ethernet Interface has entered Maintenance state to
permit resetting of the user parameter(s). The Ethernet Interface does generate an entry in its
exception log.
■
The TCP tallies CurEstab and EstabRes do not always report the correct value.
■
An Information Report channel may remain in the AWAIT_DRSP or AWAIT_CRSP state indefinitely if
the remote host fails to send a response.
■
When using VersaPro via Ethernet through this Ethernet Interface, a Clear operation that does not
include clear of Software Configuration causes VersaPro to stop responding. This behavior is not
observed using the other Ethernet programmers or if VersaPro is connected to the PLC via the
Ethernet Interface within an IC693CPU364. Rebooting the VersaPro host PC is often required to reestablish communication with the PLC.
Additional Restrictions with CPU Firmware Earlier Than Version 6.50
Ethernet Programming Not Supported
Using a PLC programmer via Ethernet requires IC693 CPU version 6.5 or later. The programmer may
appear to connect with a PLC using older CPU firmware, but essential functions will not work correctly.
CAUTION
Do not attempt to use an Ethernet programmer with CPU firmware earlier than
version 6.50. Unpredictable operation of the PLC CPU and MS-DOS
programming software will occur.
Single Incoming Network Connection to CPU
PLC CPU firmware versions earlier than 6.50 can support only one incoming network connection through
the Ethernet Interface at a time. The Ethernet Interface consequently supports only one incoming
connection at a time when used with this CPU firmware.
Important Product Information

GFK-1085X
No Operation in Expansion or Remote Rack
With CPU firmware versions earlier than 6.50, locate the Ethernet Interface in the main PLC rack only
(Rack 0, which contains the CPU). The Ethernet Interface is not supported by this CPU firmware in an
expansion or remote PLC rack.
Incoming Network Connection May Be Refused After Restart
After any restart, including power up, the Ethernet Interface is unable to accept incoming network
connections for approximately 2.5 seconds after the LAN Interface OK bit of the LAN Interface Status
Word is set. This occurs only with CPU firmware earlier than version 6.50.
Unconfigured Ethernet Interface Inoperative for Two Minutes After Restart
With CPU firmware versions earlier than 6.50, an unconfigured Ethernet Interface waits for two minutes
after each restart to receive valid configuration data from the PLC CPU. The interface slowly flashes its
Module OK LED and is not operational during this time. This behavior occurs when a new interface is
powered on for the first time. It also occurs when a PLC Programmer user clears the PLC configuration,
or stores a new configuration with an empty slot or different module type at the location where the
Ethernet Interface is installed.
Operational Notes
Remote Station Manager access is disabled until the Station manager password is changed
GE Intelligent Platforms strongly recommends that you change the Station Manager password to a value
other than the default. Until the Station Manager password has been changed to a value other than
“system”, the password vulnerabilities will remain exploitable via the serial Station Manager and all
access to Modify-level commands will be disabled on the Ethernet remote Station Manager.
Modbus/TCP or SRTP connections get closed after inactivity of 7 minutes or more
After establishing Modbus/TCP or SRTP connection, if there is no communication activity on the
connection for 7 minutes or more, the idle timer will expire and the TCP connection will be closed.
Power Loss During Field Upgrade Newer May Leave Ethernet Module Inoperative
The field upgrade kit for release 3.14 (including ZIP files downloaded from the Technical Support Web
site) replaces the software loader of the IC693CMM321, as well as the TCP/IP software, when the
module contains firmware version 3.10 or older before the upgrade. A power interruption during the
approximately three seconds required to re-program flash memory with the new software loader will
cause the module to become completely inoperative. To recover from this condition, the module must be
returned to the factory.
CAUTION
DO NOT attempt to upgrade your IC693CMM321 to release 3.14 from release
3.10 or older unless your Series 90-30 PLC has a reliable power source.
DO NOT turn power off during the upgrade process.

GFK-1085X
This Firmware Release is Incompatible with Version IC693CMM321-Ex or Older Hardware
You should not attempt to use this firmware with older versions of this module. If this firmware version
were to be loaded to an IC693CMM321-Ex or older version of this module, the module would not function
as expected, and the following symptoms would be observed:
1. The interface is unable to go online.
2. The STAT and SER LEDs blink alternately at a ½-second rate.
3. The LAN Interface OK and LAN OK bits in the LAN Interface Status Word remain off.
4. A PLC fault with text "LAN system-software fault; resuming" occurs.
5. A System log event (Event 2, entry 2 = 0401H) occurs in the Station Manager event log.
6. The following “incompatible hardware” message is printed to the Station Manager display from
the NODE and STAT L commands:
This firmware version requires IC693CMM321-F or later hardware. Your hardware version is
incompatible, and the network interface is unable to go online. To recover, use the firmware
loader to reload firmware version 2.20. It is available from the PLC Technical Support web page.
See the TCP/IP Ethernet Communications User's Manual, GFK-1541 for details.
To restore correct operation, update the module firmware to version 2.20. If you do not have the version
2.20 field upgrade kit, part number 44A737842-G05, download the file cmm321-r220.zip from the PLC
Technical Support web page, unzip the file, and then follow the instructions in cmm321update.doc
(included in the ZIP file).
System Requirements
This version of Ethernet Interface firmware requires Series 90-30 CPU firmware version 6.50 or later for
full operation. Restricted operation is available with CPU firmware version 5.03 or later (6.03 for the Model
351 CPU). However, Ethernet Interface users are strongly urged to update their CPU firmware. See
“Additional Restrictions with CPU Firmware Earlier than Version 6.50” on page 3.
Connecting to PLC programming software via Ethernet requires both IC693 CPU version 6.50 (or later
version) and Ethernet Interface version 1.10 or higher.
Power Supply Requirements
■
The Ethernet Interface requires PLC Power Supply IC693PWR321 (Rev. K or later),
IC693PWR322, or IC693PWR330.
■
Power consumption of the Ethernet Interface module is 700mA @ +5VDC
Configuration Through Serial Port Required Before Using Ethernet Communications
The Ethernet Interface cannot operate on the network until a valid IP address is configured. The
necessary Ethernet addressing information must be configured prior to actual network operation. Two
methods are available:
1. Perform the initial configuration using a PLC Programmer through the PLC CPU serial port.
2. Connect a serial terminal to the Station Manager port (port 1) of the Ethernet Interface module.
Then use the CHSOSW command to enter a temporary IP address. The interface can then be
reached by a PLC programmer via Ethernet. See TCP/IP Ethernet Communications for the PLC
Station Manager Manual for details.
Important Product Information

GFK-1085X
Proper IP Addressing is Always Essential
The Ethernet Interface must be configured with the correct IP Address for proper operation in a TCP/IP
Ethernet network. Use of incorrect IP addresses can disrupt network operation. Refer to TCP/IP Ethernet
Communications User’s Manual for important information on IP addressing.
No HHP Support
The Hand Held Programmer (IC693PRG300) may not be used to configure the Ethernet Interface. Do not
attempt to configure the Ethernet Interface or to read its configuration with the HHP. Such attempts may
result in erroneous Loss-of-Module faults in the PLC Fault Table or other unexpected behavior.
Serial Load/Store of Register Table Causes Ethernet Programmers to Lose Communication
A load or store of the PLC Register (%R) table by a PLC Programmer connected through the CPU serial
port can cause Ethernet applications that use the PLC programmer communication window to lose
communication. This condition occurs when the load/store operation requires more than 10 seconds to
complete. For example, transferring the %R table of a CPU341, CPU35x, CPU36x or CPU37x at 19,200
baud or less will cause the timeout. The Ethernet Interface posts two or more PLC faults with the text
“LAN system-software fault; resuming”, and fault-specific data starting with 080008 and/or 080042. In
addition, faults with text “Bad remote application request; discarded request” (1B0021) and “Local request
to send rejected; discarded request” (110005) may occur. The STAT LED on the Ethernet Interface
goes out.
Logicmaster 90-30 TCP/IP Software Briefly Loses Communication When Configuration Cleared
or Stored
Clearing or storing the PLC configuration causes the MS-DOS Ethernet programming software to display
a flashing “NO COMMUNICATIONS” message for one or two seconds. PLC faults similar to those listed
under “Serial Load/Store of Register Table Causes Ethernet Programmers to Lose Communication”
above occur; the STAT LED on the Ethernet Interface goes out. In some cases, a 10 second delay occurs
before loss of communication is detected.
When the PLC configuration is stored from the MS-DOS Ethernet programming software, the
communications loss occurs immediately after successful completion of the store. Attempts to store
configuration plus logic and/or reference tables in one operation can fail. However, storing configuration
separately from logic or reference tables will always succeed.
See “Restrictions and Open Problems” on page 3 for a description of operational behavior when
configuration is cleared or stored using VersaPro.
Clearing Slot Configuration Closes TCP Connections
When the PLC CPU contains version 6.50 or later firmware, clearing the slot configuration of the Ethernet
Interface causes the interface to close all of its TCP connections immediately. The Ethernet Interface slot
configuration is cleared when a PLC Programmer connected via Ethernet clears the PLC configuration, or
stores a new configuration with an empty slot or different module type at the location where the interface
is installed. PLC faults similar to those listed under “Serial Load/Store of Register Table Causes Ethernet
Programmers to Lose Communication” above occur; the STAT LED on the Ethernet Interface goes out.
Applications that use the Ethernet Interface’s SRTP server, such as Host Communications Toolkit client
applications, must be aware that the connection has closed and take action to establish a new
connection.

GFK-1085X
Extra Channels Data Transfer Entering STOP/IOSCAN Mode
Use caution when configuring the PLC CPU to scan I/O in STOP mode. There is a small time delay
between a RUN to STOP/IOSCAN mode transition in the PLC CPU and the time when the Ethernet
Interface deactivates repeating channels. The length of this delay varies with the PLC hardware
configuration and the application program. In some cases, the time delay will be long enough that one
data transfer by a repeating channel will occur after the CPU mode transition.
After a RUN to STOP/NO IO mode transition, the Ethernet Interface aborts repeating channels
immediately.
RUN Mode Program Store
A store of a folder containing large (greater than 14K bytes) program blocks using a PLC Programmer via
Ethernet may fail and result in momentary loss of communication. This condition has been observed only
when attempting to store a large program to a PLC which is in RUN mode, and which is configured to use
a limited communication window. These conditions cause the store operation to take the maximum
possible period to complete. The failure may occur if this period exceeds 10 seconds for an individual
program block. If this problem does occur, one of the following options may be used to complete the store
operation successfully:
1. Change the PLC configuration to use Run-to-Completion mode instead of a Limited Communication
Window for the store operation.
2. Change the PLC from RUN to STOP mode to complete the store.
3. Structure the folder being stored to eliminate large program blocks or subroutine blocks. This will
minimize the chance that any single block will take longer than the maximum 10-second period
allowed for storage of that block.

Changes and Additions to User’s Manuals
TCP/IP Ethernet Communications User’s Manual
The following changes will be made in Version C of the TCP/IP Ethernet Communications User’s Manual,
GFK-1541B at its next revision.
Chapter 4, “Minor Error Codes for Major Error Codes 90H (Client API Error)”
The description of Error Status 8890H should read “Invalid channel number or channel is in an inactive
state (for example, the remote device has been turned off or disconnected, or the ‘killms’ Station Manager
command was used at the remote device to stop the channel)”.
Chapter 5, “Exchange Status Word Error Codes”
The following error codes should be added:
5
C
Stale data sample
14
C
30
C
Data size
mismatch error
Major signature
mismatch
The producer has indicated that the data sent was stale (data has not been
updated) at the time it was produced. The exchange is used.
The data size of a consumed exchange does not match the exchange
definition. The exchange is ignored.
Producer and consumer signatures are different, indicating a mismatched
configuration. The exchange is ignored.
Chapter 6, “TCP Port Numbers” (new section, follows “MAC Addresses” section)
The TCP port number on which the SRTP server listens for incoming messages is 18245 (decimal).
The TCP port number on which the Modbus/TCP server listens for incoming messages is 502 (decimal).
Appendix E, Table E-1 “Modbus Register/IC693CMM321 Reference Table Translation”
Note that current Series 90-30 PLCs support 2048 bits of %I and %Q. The mapping table shows 4096
bits, for potential future growth. Do not attempt to read %I or %Q bits beyond 2048.
Station Manager Manual
The following will be added to the TCP/IP Ethernet Communications for the Series 90 PLC Station
Manager Manual, GFK-1186G at its next revision.
In Table B-2, Exception Log Event Codes for Style A Station Manager, add the following:
Log Event Code
Event “2”
System Events
Event “11”
Possible Cause and Resolution
This event is logged by the system when a catastrophic system event occurs.
Entry 2 (hexadecimal) codes are as follows:
System Error: 05
“LAN system-software fault; resuming”
During a field upgrade to a new software revision, an apparent hardware failure has
caused repeated attempts to erase or re-program flash memory to fail. The Ethernet
module may be completely inoperative after it is powered off or restarted. If so, it must
be replaced.
The additional value 12H for Entry 2 is possible. It indicates an internal system
software error that should be reported to the manufacturer.
Tally Descriptions (Appendix C)
In Table C-6 “ICMP Tallies”, the tally “Filtered” should be described as:
Filtered
Number of ICMP messages ignored because they are not directly addressed to this
node, or because this node has detected an invalid source address for an incoming
IP or ICMP message.
