Actual values
6.1 Overview
6.1.1 Message Map
Measured values, event records and product information are actual values. Actual values
may be accessed via any of the following methods:
• Front panel, using the keys and display.
• Front program port or rear Ethernet port and a portable computer running the
EnerVista 745 Setup software supplied with the relay.
• Rear RS485/RS422 COM 1 port or RS485 COM 2 port with any system running user
written software.
Any of these methods can be used to view the same information. A computer, however,
makes viewing much more convenient, since more than one piece of information can be
viewed at the same time.
