Appendix

C

PC Software Loader

Note

For the IC693CPU374, operating firmware for both the PLC CPU and the Embedded Ethernet

Interface are upgraded via the power supply serial port. This appendix does not apply to the

CPU374. See <reference CPU manual? here>for CPU374 upgrade instructions .

The GE Fanuc Series 90 Ethernet Interface has its operating firmware stored in FLASH memory as opposed to EPROMS. You can perform a firmware upgrade for your Ethernet Interface while the PLC remains powered on and running. However, Ethernet communication through your Interface will be interrupted until the upgrade has completed successfully.

A firmware upgrade for the Ethernet Interface is provided on a floppy diskette. A Firmware Update Utility, provided on the floppy diskette in both a Windows-based and a DOS-based version, controls the download of new firmware from the floppy diskette to the FLASH memory. To perform the upgrade using a personal computer (PC) running Windows 95, Windows 98, or Windows NT 4.0, refer to the section “Updating Firmware Under Windows” below for instructions to use the WinLoader program. To perform the upgrade using a PC running MS- DOS(Revision 3.3 or higher), Windows 3.11, or Windows NT 3.51, refer to the section “Updating Firmware Under DOS and Windows 3.xx” later in this appendix for instructions to use the PC Software Loader program. The program that you run on the PC is referred to as the ”Firmware Update Utility” in the instructions that follow.

Note

For the Series 90-70 Ethernet Interface (Type 2) only, it is not possible to perform a firmware load to this Ethernet Interface while it is operating with an IC697 PLC CPU running firmware Release 4.12 through 5.50. Do not attempt to do so - the operation will fail. Move the Interface to a IC697 PLC CPU system running firmware Release 6.00 or higher to perform the firmware load.
