We compare various modes of firing transitions in Petri nets and define classes of languages defined this way. We define languages through steps, i. e. sets of transitions, maximal steps, multi-steps, and maximal multi-steps of transitions in Petri nets, but in a different manner than those defined in [Burk 81a,Burk 83], by considering labeled transitions. We will show that we obtain a hierarchy of families of languages defined by multiple use of transition in firing transitions in a single multistep. Except for the maximal multi-steps all classes can be simulated by sequential firing of transitions.
