Base component for a circuit breaker.

 A circuit breaker is a automatically-operated electrical switch, designed to
 protect an electrical circuit from damage caused by overload or short circuit.

 The object supervises a digital input signal and when the signal is lost,
 an alarm is generated.

 The alarm can be disabled by setting the DisableSup input in the function
 object. This does not affect the Tripped output in the function object.

 When the circuit breaker is tripped, the Tripped indicator is colored red.
 There is also an indicator that shows if the alarm is disabled.

 The figure shows a configuration with a circuit breaker.

Configuration

 The object contains the Di signal 'NotTripped' that should be connected to a
 Di-channel.

 For plc coding the function object BaseCircuitBreakerFo is used.

 Create a function object in the plc editor and connect it to the current
 object with the connect function.

 No simulate object is needed for BaseCircuitBreaker, but there is a
 simulate graph from where the Tripped signal can be affected.

 This attribute is set when the function object is connected from
 the plc editor by the connect function.
