Virtual Switches (x43 & 101)
You can assign a meaningful name or label to each of the four virtual switches (
Figure 14-38). This
makes sequential events reports easier to analyze. To assign a meaningful label to Virtual Switch 43,
click in the Label field and enter the new name. To change the label for the True State, click on the True
State field and enter the new name. To change the label for the False State, click on the False State field
and enter the new name. The remaining four virtual switches function the same way.
The mode logic setting for Virtual Switch 43 can be made by clicking on the BESTlogic button and, with
your custom logic selected, select the mode logic by using the Mode pull-down menu. The remaining
three virtual switches have the same functions.
The Virtual Breaker Control Switch (101) provides manual control of a circuit breaker or switch without
using physical switches and/or interposing relays. The mode logic setting for Virtual Breaker Control
Switch 101 can be made by clicking on its associated BESTlogic button and, with your custom logic
selected, select the mode logic by using the Mode pull-down menu. Trip outputs include Trip, Close, and
Slip Contact.
