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
Communications from the EnerVista 745 Setup to the 745 can be accomplished three
ways: RS232, RS485, and Ethernet communications. The following figures below illustrate
typical connections for RS232, RS485, and Ethernet communications.
