This block can be configured with multiple inputs, such as SDC and/or STE blocks. A logic group can be
associated with each of these: AND/OR/DIS. The rule that is executed is (∑And | ∑Or) & ∑!Dis where
And=AND logic of all parameters in AND;
Or=OR logic of all parameters in OR;
Dis=NOT logic of all parameters in DIS.
Example with C=Condition of Input (SDC/STE):
C1 AND
C2 OR
C3 AND
C4 OR
C5 AND
C6 DIS
C7 DIS
The resulting logic is: ( (C1&C3&C5) | C2 | C4 ) & !C7 & !C6
The logic configured for each input is shown on the project screen as a label on the same inputs. As
illustrated in the above image.
