In the Set Trigger Logic display, select the And operator (*) or the Or
operator (+) under Mask Operator to set the logical relationship for two
or more inputs. These three examples illustrate the logic for three distinct
triggers:
In1*In2 The trigger is asserted when both Input 1 and
Input 2 are true.
In1+In2 The trigger is asserted when either Input 1 or
Input 2 is true.
In1*~In2 The trigger is asserted when Input 1 is true and
Input 2 is not true.
Click Group inputs to place parentheses around a series of inputs in the
Logic field. Then select a group operator to set the logical relationship
between the group and another input or group of inputs. For example:
(In1*In2*In3*In4*In5*In6*In7)+In8
The trigger is asserted when Inputs 1 through 7 are
true, or when Input 8 is true.
(In1+In2+In3+In4+In5+In6+In7)*In8
The trigger is asserted when one of the first seven
inputs is true, and Input 8 is true.
Three restrictions govern the formation of logical expressions that use a
group operator:
• The mask operator for all of the inputs inside the parentheses
must be the same.
• The group operator outside the parentheses must be the opposite
of the mask operator inside the parentheses.
Click Delete last to delete the last input entered in the Logic field. To
clear all the inputs from the Logic field, click Delete last until all the
inputs are deleted.
