After successfully updating the 345 firmware, the relay will not be in service and will
require setpoint programming. To communicate with the relay, the communication
settings may have to be manually reprogrammed.
When communications is established, the saved setpoints must be reloaded back into the
relay. See Loading Setpoints from a File for details.
Modbus addresses assigned to firmware modules, features, settings, and 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 FlexCurve Editor is designed to allow the user to graphically view and edit the
FlexCurve. The Flexcurve Editor screen is shown below:
• The Operate Curves are displayed, which can be edited by dragging the tips of the
curves
• A Base curve can be plotted for reference, to customize the operating curve. The Blue
colored curve in the picture (in both curves) is a reference curve. It can be Extremely
Inverse, Definite Time, etc.
