5.1. Practical advice
●

● For complementing
 To complement a variable or the result of a Boolean function just double-click on the right
extremity of the linking line between a variable and a block.
In this example, the
I62.00 and I62.01 variables are complemented as well as the result of the
Boolean function.
%I62.00
%I62.01 %M000.00
&
 In order to effectuate the complement of a variable in Quick LD, just select the contact or
output and press the space bar. Each time you press the space bar the property of the
contact or output is modified.
%I62.01 %M000.00
%I62.00
%M000.00
&
%O62.00

● Duplicating
 The duplication of inputs is carried out by modifying the block property with a double-click
and selecting the number of inputs from the scrolling
"Number of inputs" menu
(see Figure 5-10).
The duplication number varies depending on the block used.
