To order an upgrade kit, write down the full catalog number of your module from the module
identification label on the side of the module, determine your current firmware revision level, then
call your PLC distributor. If you are not sure what firmware version you currently have, see the
heading on the next page "Determining CPU Revision Levels (Versions)."
Flash Firmware Upgrade Procedure
The operating system firmware is updated by connecting a PC compatible computer to the
applicable PLC serial port and running the PC Loader software included with the firmware floppy
disk.
The computer used for this task should be an IBM AT compatible or better PC with a minimum
640K of RAM, one 3.5" or high density 5.25" floppy drive, MS-DOS version 3.3 or later, a hard
drive, and an RS-232 serial port. In addition, a miniconverter/serial cable is required. The following
miniconverter/serial cable kit is available:
Determining CPU Revision Levels (Versions)
If you plan to make changes to your system, you will need to know if your CPU can support those
changes. The features and capabilities of your CPU are determined by its revision levels (hardware
and firmware). This section discusses methods that you can use to determine your CPU's revision
levels and associated features and capabilities.

the power supply, or through a port on the front of the CPU module (if it has one). The
applicable method will be documented in your upgrade kit instructions. Downloadable
firmware upgrade files are also found in the Technical Support area of the GE Web site.

(This product is documented in Appendix D.)
Obtain the information from the Important Product Information (IPI) sheet that came with your
CPU. However, if your CPU firmware has been upgraded, the IPI will not indicate the current
revision level.
The surest way to determine a CPU's firmware revision level is to read it from the CPU by
using your programmer. Your programmer must be connected to the PLC and be in Online or
Monitor mode, and the PLC must be powered up. For example, on the Logicmaster "PLC
STATUS and CONTROL" screen is an item called "SOFTWARE REVISION." The data
displayed in that field (such as 6.04) is the firmware revision level. See the Logicmaster 90-30
Programming Software User's Manual, GFK-0466 (or the user's manual for the programming
software you use), for additional details.
Check the catalog number printed on the module identification label on the side of the module.
On all Series 90-30 modules, this catalog number indicates the module's revision level(s). For
some CPUs, the catalog number contains a single letter at the end to indicate the CPU's overall
revision level. For example,
