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.
