Protection inputs and outputs
Three groupings of protection inputs and outputs are defined: physical, shared, and virtual.
Within these three groupings there are two types: analog and digital.
Protection virtual inputs
There are 64 virtual inputs that can be programmed individually to respond to input signals
from the front panel interface and communications protocols. All virtual input operands
are defaulted to off (logic 0) unless the appropriate input signal is received.
Select the Settings > Protection > Protection Inputs/Outputs > Virtual Inputs menu to
access the protection virtual input configuration settings.
