IMPORTANT PRODUCT INFORMATION
READ THIS INFORMATION FIRST
Product:
Series 90-30 CPU Module with Firmware Release 9.11
IC693CPU351-KT
This hardware revision replaces an obsolete cache RAM with a component that is currently available. At
room temperature, the new part reduces the battery life from 6 years to 10 months.
Firmware release 9.11 applies to the model CPU351 only. This release resolves the problem of the write to
flash memory failure that occurred during a Store to User Flash operation when flash memory was subjected
to temperature cycles. (See "Problems Resolved in Release 9.11” on page 1.)
Upgrades
No field upgrade is required or available for this hardware revision.
If you wish to upgrade an existing CPU351 to firmware version 9.11, you may purchase the applicable kit or
download it at no charge from http://support.gefanuc.com/. Firmware upgrades require the IC690ACC901
Miniconverter and Cable Kit. All previous versions are capable of being upgraded.
Upgrade kit: 44A736935-G14
Functional Compatibility
With the original cache RAM component, the battery life was 6 years 25°C and 1½ years at 60°C.
The data retention current on the currently available part reduces the battery life to 10 months at
25°C and 5½ months at 60°C.
Machine Edition Logic Developer-PLC software and VersaPro software version 1.10 support all
features of this CPU except Sequential Function Chart (SFC).
Control programming software, version 2.00 or later is required to take advantage of SFC
subroutines. C programming requires version 2.00 or later of this software.
Version 4.00 or later of the C toolkit must be used for C programming.
If you use Logicmaster Programming Software, version 9.02 is required to take advantage of the
features introduced in firmware release 9.00 and later CPU351 releases.
Problems Resolved by this Hardware Revision
The original cache RAM component is obsolete and no longer available. The new component is the lowest
power part currently available.
Problems Resolved in Firmware Version 9.11
User Flash Write and Erase Failure
User Flash Write/Erase operations would fail when the Flash Memory was subjected to significant
temperature variations. This failure is now detected correctly, an error message is displayed, and you can
retry the operation.

Restrictions and Open Issues
ALG220/221 Timing Issue May Result in Incorrect %AI Values Read by CPU
A problem was found with the IC693ALG220/221 modules where the actual %AI values reported by the card
may exhibit erratic behavior (catalog module revisions F and earlier may show this problem; revision G has
fixed this problem). Certain current or voltage levels within the input range applied to the card could cause
the %AI values to report incorrectly. The problem stems from the use of particular optocouplers, which may
exhibit timing issues with these CPU35x/36x modules.
CPUs 341, 331, 321, 313, and 311 have not exhibited this timing problem reading %AI values.
Operating Notes
Replacing an IC693CPU351 with an IC693CPU363
This topic applies to users wishing to replace an IC693CPU351 module with an IC693CPU363. The
CPU363, functionally, is fully backward compatible with the CPU351. However, there are a few items
to consider when making this replacement:
Make sure you have a backup copy of the application program folder. When the CPU351 is
removed from the PLC, the application program in its RAM memory will be lost. You must have a current
backup copy available to store to the new CPU363. So before proceeding, ensure that your backup
copy is up-to-date. If you do not have a current backup copy, you can load the application program
(include ladder logic, configuration, and registers) from the PLC to your computer to create a current
backup copy. As an extra margin of safety, you could also write the application program from RAM
memory to flash memory in the CPU351 before removing it from the PLC; this would create a nonvolatile copy of the program inside the CPU351. See your programming software’s user’s manual or online help for instructions on writing to a CPU’s Flash memory.
CPU351 will not receive feature upgrades beyond firmware release 9.11. Therefore, it does not have the
features that were added to the CPU363 in firmware release 10.00 and beyond.
The front panel serial port connectors, labeled Port 1 and Port 2, are oriented differently between
CPU351 and CPU363 (they are rotated 180 degrees). This could impact CPU351 installations that use a
right-angle connector to connect to Port 2. In that case, the Port 2 cable may have to be re-routed or the
connector orientation may have to be reversed to allow it to connect to the CPU363.
There is a difference in the location of the module shield ground tab. On the CPU351, it is on the bottom
of the module; on the CPU363, it is on the module’s front panel. Therefore, in substituting a CPU363, a
new ground wire (supplied with the module) will have to be installed if the wire from the CPU351
installation is too short.
The CPU351, in some installations, uses a ground shield bracket that fastens to the bottom of the
module and to the back of the enclosure or mounting panel. This ground shield bracket is not required
on the CPU363 since this module has superior noise immunity compared with the CPU351. Therefore,
the ground shield bracket should be removed when replacing a CPU351 with a CPU363. Details on
CPU module shield grounding can be found in the latest IC693 Installation and Hardware manual.
Before storing the application program folder from your programmer to the CPU363, it is necessary to
perform the following steps. (1) Record all configuration settings of the CPU351 (including SNP ID, if
used, and communications settings). If a printer is available, you can print the CPU settings. (2) On
your configuration screen, replace the CPU351 with the CPU363. (3) Finally, set the CPU363
configuration settings to match those of the CPU351 recorded in step 1.
Also, don’t forget to update all backup folders and documentation to reflect this change.

Note:
The top LED is labeled “SNP” on the CPU351 and “PS Port” on the CPU363. These both refer to the
built-in serial port that is accessed through the 15-pin D-shell connector on the PLC main rack
(Rack 0) power supply.
User Flash Contents
User information, consisting of program, configuration, CPU ID (used for SNP communications), and status
tables in RAM memory, will automatically be cleared if the CPU firmware in flash memory is changed. You
will need to restore these if upgrading firmware. A recommended procedure is to first back up your user
information from RAM memory to flash memory. Then write your new firmware to flash memory (firmware is
stored in a different location in Flash memory than that used for storing user information such as program,
configuration, etc.). Finally, write your user information back out of Flash into RAM memory. As an
alternative, your user information (program, configuration, etc.) can be restored from a computer-based
backup program folder using your PLC programming software. The SNP ID must be set separately, using the
programming software or the Hand-Held Programmer (HHP).
Firmware Upgrade Hardware Requirements
The CPU351 operating firmware is stored in FLASH memory. The firmware upgrade is provided on a floppy
disk (see previous page for upgrade kit number) and must be serially downloaded from a Personal
Computer. An IBM AT personal computer or better PC with a minimum 640K of RAM, one 3.5” floppy drive,
MS-DOS version 3.3 or later (or Windows 95 or later), a hard drive, and one RS-232 serial port is required.
In addition, a serial cable is required. The following serial cable is available:
IC690ACC901 Mini Converter Kit with cable (RS-232/RS-485).
Changing Firmware to an Earlier Version
If you have a CPU351 with firmware version 9.00 (or later), and you want to install a pre-9.00 version of
firmware, a special upgrade disk must be obtained from your distributor. Do not attempt to use a firmware
version 8.10 or earlier upgrade disk on a CPU that contains firmware version 9.00.
Option Module Revision Requirements
Ethernet Interface Module Compatibility. All IC693 Ethernet Interface (IC693CMM321) modules used
with these CPUs should be updated to IC693CMM321 firmware release 1.10 or later. This is also a
requirement of the TCP/IP Ethernet version of the MS-DOS programming software. During a Run Mode
Store (Alt + S hot key combination) of a large program block (greater than 14 kilobytes), the Ethernet
module may time out, causing communications to fail. Changing the Communications Window to Runto-Completion mode, or storing the program in Stop mode, will allow the store to take place successfully.
FBC Compatibility. FBC version 3 or later is required for these CPUs.
Writing Flash Using a Serial Programmer
When writing very large programs to flash memory, it may be necessary to increase the programming
software request timeout value to avoid receiving a request timeout message. An upper bound of 25
seconds is typically satisfactory.
When port 1 is being used under a heavy load and a store is simultaneously attempted from the programmer
through port 2, it is possible for the store to fail and require a re-try. If this occurs, a fault will be logged in the
PLC fault table indicating that the store did not succeed.
