XOR Gate Custom logic XOR gates always have two sources (‘inputs’) only. The output
of an XOR gate goes High if the two defined sources are different ; or, in other
words, it goes
Low
if
both
defined sources are
either High or Low
. Refer to
the truth table below.

NOT Gate
Custom logic NOT gates always have one single source (‘input’). The output
of a NOT gate goes High if the defined source is Low, and vice versa . The
simple ‘truth table’ below has been added for completeness.

Common for AND and OR Gates
Undefined sources are ignored, which means that the gate has just as many
inputs (2...6) as defined with the configuration tool.
The default value of the (output) level is Low.
Common for XOR and NOT Gates The output level is always Low as long as at least one of the sources (‘inputs’)
is undefined.
Common for All Gates
The following is valid for all types of custom logic gates:
The default value of the output level is Low. It is used for defined local sources
that are unavailable.
The default value of the ‘Replacement Value’ is Low. It is used for defined
remote sources that are unavailable.
The labels are initialized by the software as ‘AND nnn’, ‘OR nnn’, ‘XOR
nnn’ or ‘NOT nnn’, respectively.
The number of available gates is defined in the
CustomLogics.xml
file.
Since custom logic gates are (net-) consumers, they also allow the definition
of a ‘level producer’. The following producers are allowed:
• Local or remote GPInputs
• Local or remote GPOutput Functions
• Local or remote Custom Logic.
