enerVista Software Interface
Overview The front panel provides local operator interface with a liquid crystal display. The
enerVista 745 Setup software provides a graphical user interface (GUI) as one of
two human interfaces to a 745 device. The alternate human interface is
implemented via the device's faceplate keypad and display (see the first section in
this chapter).
The enerVista 745 Setup software provides a single facility to configure, monitor,
maintain, and trouble-shoot the operation of relay functions, connected over serial
communication networks. It can be used while disconnected (i.e. off-line) or
connected (i.e. on-line) to a 745 device. In off-line mode, settings files can be
created for eventual downloading to the device. In on-line mode, you can
communicate with the device in real-time.
This no-charge software, provided with every 745 relay, can be run from any
computer supporting Microsoft Windows
®
95 or higher. This chapter provides a
summary of the basic enerVista 745 Setup software interface features. The
enerVista 745 Setup help file provides details for getting started and using the
software interface.
With the enerVista 745 Setup running on your PC, it is possible to
• Program and modify setpoints
• Load/save setpoint files from/to disk
• Read actual values and monitor status
• Perform waveform capture and log data
• Plot, print, and view trending graphs of selected actual values
• Download and playback waveforms
• Get help on any topic
Hardware Communications from the enerVista 745 Setup to the 745 can be accomplished
three ways: RS232, RS485, and Ethernet (requires the MultiNET adapter)
communications. The following figures below illustrate typical connections for RS232
and RS485 communications. For additional details on Ethernet communications,
please see the MultiNET manual (GE Publication number GEK-106498).
