Abstract: A formal relation between Condition/Event-systems and Place/Transition-systems ist presented using basics of net topology and the concept of synchronic distance. Basics of net topology are used to construct and interconnect functional units of a C/E-system, synchronic distances are used to abstract from these functional units and get a P/T-system.
