S3 Logic Inputs
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.
