The transition condition is formulated as a boolean expression which can be
made up of a maximum of 10 individual conditions. An individual condition
consists of two operands (1st operand = variable, 2nd operand = variable or
number) which are linked to each other by a comparator. The expressions
thereby defined are linked again via a boolean operator, thus causing a
boolean value to be calculated as the transition result.
If you double-click on a transition you can use the following transition dialog
for transition planning:

Via the 'Inputs' button you can make any changes you like to the standard
defaults toggle (6 conditions for gate 1 and 4 conditions for gate 2). In
addition, by clicking on AND you can immediately change the logic
operation into OR, NAND or NOR.
In the case of the individual conditions the comparators =, <>, >=, <=, >, <
are available. The operator is simple to change: just click on it.
