Upgrading Relay Firmware
NOTE
GE Multilin
8. The EnerVista 469 Setup software now prepares the 469 to receive the new
firmware file. The 469 will display a message indicating that it is in Upload
Mode. While the file is being loaded into the 469, a status box appears showing
how much of the new firmware file has been transferred and how much is
remaining, as well as the upgrade status. The entire transfer process takes
approximately five minutes.
9. The EnerVista 469 Setup software will notify the user when the 469 has finished
loading the file. Carefully read any displayed messages and click OK to return
the main screen.
Cycling power to the relay is recommended after a firmware upgrade.
After successfully updating the 469 firmware, the relay will not be in service and will
require setpoint programming. To communicate with the relay, the following settings
will have to me manually programmed.
MODBUS COMMUNICATION ADDRESS
BAUD RATE
(if applicable)
PARITY
When communications is established, the saved setpoints must be reloaded back
into the relay. See Loading Setpoints from a File on page 4–21 for details.
Modbus addresses assigned
corresponding data items (i.e. default values, min/max values, data type, and item
size) may change slightly from version to version of firmware.
The addresses are rearranged when new features are added or existing features are
enhanced or modified. The
upgrading/downgrading the firmware is a resettable, self-test message intended to
inform users that the Modbus addresses have changed with the upgraded firmware.
This message does not signal any problems when appearing after firmware
upgrades.
