5.4.7 Logical outputs
Logical outputs are used for sending binary signals out from a logic that has been built in the logic
editor. Logical signals can be used for blocking functions, changing setting groups, controlling digital
outputs, activating LEDs, etc. The status of logical outputs can also be reported to a SCADA system.
64 logical outputs are available. The figure below presents a logic output example where a signal from
the circuit breaker failure protection function controls the digital output relay number 5 ("OUT5") when
the circuit breaker's cart status is "In". The image above is from the logic editor and the image below
from AQtivate 200.
