5 ACTUAL VALUES 5.1 OVERVIEW
Measured values, maintenance and fault analysis information are accessed in the Actual Value mode. Actual values may
be accessed via one of the following methods:
1.
Front panel, using the keys and display.
2.
Front program port, and a portable computer running the 489PC software supplied with the relay.
3.
Rear terminal RS485 port, and a PLC/SCADA system running user-written software.
Any of these methods can be used to view the same information. However, a computer makes viewing much more conve-
nient since many variables may be viewed simultaneously.
Actual value messages are organized into logical groups, or pages, for easy reference, as shown below. All actual value
messages are illustrated and described in blocks throughout this chapter. All values shown in these message illustrations
assume that no inputs (besides control power) are connected to the 489.
