8. The EnerVista 750/760 Setup software now prepares the 750/760 to receive the
new firmware file. The 750/760 will display a message indicating that it is in
Upload Mode. While the file is being loaded into the 750/760, 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 750/760 Setup software will notify the user when the 750/760
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 750/760 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 4–23 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.
