CHAPTER 4: INTERFACES
4.2 EnerVista Software Interface
4.2.1 Overview
The front panel provides local operator interface with a liquid crystal display. The EnerVista
489 Setup software provides a graphical user interface (GUI) as one of two human
interfaces to a 489 device. The alternate human interface is implemented via the device's
faceplate keypad and display (see the first section in this chapter).
The EnerVista 489 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 489
device. In off-line mode, setpoint 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 489 relay, can be run from any computer
supporting Microsoft Windows
®
95 or higher. This chapter provides a summary of the
basic EnerVista 489 Setup software interface features. The EnerVista 489 Setup help file
provides details for getting started and using the software interface.
With the EnerVista 489 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
4.2.2 Hardware
Communications from the EnerVista 489 Setup to the 489 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).
