4.4.3 File Support
Opening any EnerVista 745 Setup file will automatically launch the application or provide
focus to the already opened application. If the file is a settings file (has a ‘745’ extension)
which had been removed from the Settings List tree menu, it will be added back to the
Settings List tree.
New files will be automatically added to the tree, which is sorted alphabetically with
respect to settings file names.
4.4.4 Using Setpoints Files
4.4.4.1 Overview
The EnerVista 745 Setup software interface supports three ways of handling changes to
relay settings:
•In off-line mode (relay disconnected) to create or edit relay settings files for later
download to communicating relays.
• Directly modifying relay settings while connected to a communicating relay, then
saving the settings when complete.
• Creating/editing settings files while connected to a communicating relay, then
saving them to the relay when complete.
Settings files are organized on the basis of file names assigned by the user. A settings file
contains data pertaining to the following types of relay settings:
• Device definition
•Product setup
•System setup
• Logic inputs
• Protection elements
•Outputs
•Relay testing
• User memory map setting tool
Factory default values are supplied and can be restored after any changes.
The EnerVista 745 Setup display relay setpoints with the same hierarchy as the front panel
display. For specific details on setpoints, refer to Chapter 5.

changes or creating new setpoint files.
