First, Place Coupling Nets (PCN) and related concepts are defined. Second, the relationship between the T-invariants of the PCN and its branches nets are presented, Third, an algorithm for computing T-invariants in PCN is given. Finally, the algorithm is implemented and elementary experimental data are obtained which show that the presented algorithm has advantages in saving computation time and memory over the existing method.
