2. transisi. transisi nyaeta input
conto: saklar 1 ON, saklar 2 ON, jeung sajabana


tah ditingali tina gambar diluhur
maka, A, B jeung C mangrupakeun input atawa transisi.
jadi
T1 (transisi 1) = A (misalkan)
T2 (transisi 2) = B (misalkan)
T3 (transisi 3) = C (misalkan)
rumus pikeun nangtukeun output:
STATE A = (self + arrow in). invers arrow out
