5.5S3 LOGIC INPUTS
5.5.1 DESCRIPTION
The are two types of digital inputs:
Logic Inputs
have physical terminals for connecting to external contacts;
Virtual Inputs
provide the same function as logic inputs, but have no physical external connections. A setpoint defines the state of each in
Virtual Input in terms of “On” or “Off”.
There are 16 each of logic and virtual inputs. The state (‘asserted’ or ‘not asserted’) of each logic or virtual input can be
used to activate a variety of predefined logic functions, such as protection element blocking, energization detection, etc. In
addition, any logic or virtual input can be used as an input in FlexLogic™ equations to implement custom schemes.

LOGIC INPUT 1(16)
•
INPUT 1(16) FUNCTION
: Select “Enabled” if this logic input is to be used. Selecting “Disabled” prevents this logic input
from achieving the Asserted (or signaling) state.
•
INPUT 1(16) TARGET
: Selecting "None" inhibits target message display when the input is asserted. Thus, an input
with target type "None" never disables the LED self-test feature since it cannot generate a displayable target message.
•
INPUT 1(16) NAME
: Press
to edit the login input name. The text may be changed from "Logic Input 1" one
character at a time with the
/
keys. Press
to store and advance to the next character position.
•
INPUT 1(16) ASSERTED STATE
: Select "Closed" as when connected to a normally open contact (where the signaling
state is closed). Select "Open" when connected to a normally closed contact (where the signaling state is open).

VIRTUAL INPUT 1(16)
•
INPUT 1 FUNCTION
: Select "Enabled" if this virtual input is to be used. Selecting "Disabled" prevents this virtual input
from achieving the ‘Asserted’ (or signaling) state.
•
INPUT 1 TARGET
: Selecting "None" inhibits target message display when the input is asserted. Thus, an input whose
target type is "None" never disables the LED self-test feature since it cannot generate a displayable target message.
•
INPUT 1 NAME
: Press
to edit the login input name. The text may be changed from "Virtual Input 1" one charac-
ter at a time with the
/
keys. Press
to store and advance to the next character position.
•
INPUT 1 PROGRAMMED STATE
: Select "Asserted" to place the virtual input into the signaling state; likewise, select
"Not Asserted" to place it into the non-signaling state.
