8.3.2 469 FIRMWARE UPGRADES
Prior to downloading new firmware to the 469, it is necessary to save the 469 setpoints to a file (see the previ-
ous section). Loading new firmware into the 469 flash memory is accomplished as follows:
1.
Ensure the local PC is connected to the 469
via the front RS232 port
and that communications are estab-
lished. Save the current setpoints to a file using the procedure outlined in the previous section.
2.
Select the Communications > Upgrade Firmware menu item.
3.
A warning message will appear (remember that all previously programmed setpoints will be erased). Click
Yes to proceed or No to exit.
4.
Next, 469PC will request the name of the new firmware file. Locate the appropriate file by changing drives
and/or directories until a list of file names appears in the list box. File names for released 469 firmware
have the following format:
Figure 8–3: 469 FIRMWARE FILE FORMAT
5.
The 469PC software automatically lists all filenames beginning with 30. Select the appropriate file and click
OK to continue.
6.
469PC will prompt with the following dialog box. This will be the last chance to cancel the firmware
upgrade before the flash memory is erased. Click Yes to continue or No to cancel the upgrade.
7.
The software automatically puts the relay into “upload mode” and then begins loading the selected file.
Upon completion, the relay is placed back into “normal mode”.
8.
Upon successful updating of the 469 firmware, the relay will not be in service and will require program-
ming. To communicate with the relay via the RS485 ports, the Slave Address, Baud Rate, and Parity will
have to be manually programmed. When communications is established, the saved setpoints will have to
be reloaded back into the 469. See the next section for details.
