This chapter explains the EnerVista software interface, the front panel interface, logic diagrams, and Engineer interface for
logic design and monitoring.
4.1 EnerVista software interface
4.1.1 Introduction
The EnerVista UR Setup software provides a single facility to configure, monitor, maintain, and troubleshoot relays
connected over local or wide-area networks. It can be used while disconnected (offline) or connected (online) to a UR
device. In offline mode, settings files can be created for eventual downloading to the device. In online mode,
communication with the device is real-time.
The EnerVista UR Setup software is provided with every D30. This chapter outlines the EnerVista software interface. The
EnerVista UR Setup help file in the software also provides details for getting started and using the software interface.
4.1.2 Settings files
The EnerVista software supports the following three ways of handling changes to relay settings:
• In offline mode (relay disconnected) to create or edit relay settings files for later transfer to relays
• While connected to a relay to modify relay settings, and then save the settings to the relay
• Create/edit settings files and then write them to the relay while connected to the relay
See the back up section in the Maintenance chapter for instructions on how to create a settings file either offline or online.
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
• FlexLogic
• Grouped elements
• Control elements
• Inputs/outputs
