mode rather than firmware load mode. To return to operational mode, press and hold the restart button briefly (less than 5 seconds). Then re-execute the instructions in this step.)

If all LEDs are not blinking after this step, but your Interface seems to operate normally when first powered on, there may be a hardware failure of the loader port. Use the PLC programming software to check the PLC fault table for a "Module hardware fault" message from the rack and slot location of your Interface. You can also check the text displayed by the Ethernet Interface's local station manager NODE command for a "Power up diagnostics result" message about the Software Loader port. See TCP/IP Ethernet Communications for the Series 90 PLC Station Manager Manual, GFK-1186, for details. The Firmware Update Utility will not function if there is a hardware failure of the Ethernet Interface Software Loader port. The Interface will be inoperative until it is power cycled. It should be replaced.

7.Click the “Update” button to begin loading the new firmware. A progress bar is displayed across the bottom of the window. The firmware load will take approximately 3-4 minutes to complete at 38,400 baud rate.

8.Upon completion of the update, a dialog box will appear indicating the completion status of the update. If the load completed successfully, the Firmware Update Utility asks you if you want to update another Interface. Click “No” if this is the last update. If there are more, click “Yes”, move the serial cable to the next Interface, adjust the serial settings if necessary, prepare the Interface to receive a load, and click “Update” again.

9.If the firmware load fails, a window appears indicating the specific error condition that occurred. Take appropriate steps to correct the error and retry the update. Refer to Restarting An Interrupted Firmware Upgrade below.

10.When the firmware load has completed, the Ethernet Interface will automatically restart itself. Disconnect the serial cable.

Place the label accompanying the floppy diskette marked “UPDATED TO FIRMWARE VERSION x.xx” adjacent to existing product label.

Restarting an Interrupted Firmware Upgrade

1.Carefully check the cables, the RS-232/RS-485 converter (if used), and all connections. It is important to use the recommended cable assembly or equivalent. Use of non-standard cables (especially cables that are very long) can inhibit the Firmware Update Utility from successfully communicating with the Ethernet Interface.

2.Briefly press and release the Ethernet Interface Restart button. Depending on how far the previous upgrade progressed before it failed, your Ethernet Interface may restart in either operational mode or firmware load mode. If all LEDs are blinking simultaneously, skip to step 3 now.

If your Interface is in operational mode, press and hold the Restart button for five seconds until the lower LED lights. Release the button and verify that all LEDs are blinking simultaneously. If all LEDs are off, replace your Interface. Otherwise proceed to step 3. (Note: If you hold the restart button down too long, the Ethernet Interface will enter maintenance mode. To return to operational mode, press and hold the restart button briefly (less than 5 seconds). Then re-execute the instructions in this step.)

3.You must exit the Firmware Update Utility (on the PC) and start it again, then repeat the update process.

If your previous attempt progressed beyond the FLASH memory erase step, began loading data blocks, and then displayed an error message or stalled, try a lower baud rate. If you were using an MS-DOS box under Microsoft Windows, exit from Windows and run the Firmware Update Utility directly from MS-DOS.
