Parameters
Having connected at least one input, you can configure the value of the output in the truth table, in the
Parameters window.
The output values can be 0 for the Inactive state, and 1 for the Active state(Double click to change the
0 or 1 ).
By selecting the Output ON if result is TRUE option, the output takes the value configured in the truth
table.
By selecting the Output OFF if result is TRUE option, the output takes the inverse value of the value
configured in the truth table.

requirements.
This section provides you with a brief overview of input designations and with some particular
background information on SFs. The SFs in particular are described in Chapter7.5
