Control

I<->O CB1
The circuit-breaker function block is used for controlling the open and close
positions of a circuit breaker. The function block also takes care of the user-defined
interlocking logics and has guaranteed opening and closing pulse widths and forced
open control operations for protection purposes. The open, close and undefined
states of an object can be indicated remotely by the function block. Since the
function block is mainly designed for circuit breakers, it will issue specific alarm
signals based on the condition monitoring features.
