Specifies the Boolean logic (And/Or) to be employed in combination with source inputs in deriving a True or False outcome.

When the source input operator is unreliable, the interlock operates according to the following rules:
  • Complex - Uses the equation defined by the Logic Equations attribute. If any input is unreliable, the expression cannot be evaluated; therefore, the interlock is unreliable and does not execute.
  • Match All (AND) - Every one of the source conditions must be True. If an input is reliable, it is evaluated. If the result is False, the interlock evaluates to False and executes. All inputs are checked for trouble (Reliability != Reliable). If any input is not reliable, the expression cannot be evaluated; therefore, the interlock is unreliable and does not execute.
  • Match Any (OR) - One or more of the source conditions must be True. If an input is reliable, it is evaluated. If the result is True, the interlock evaluates to True and executes. All inputs are checked for trouble (Reliability != Reliable). If no inputs are reliable, the expression cannot be evaluated; therefore, the interlock is unreliable and does not execute.
