A programmable controller based on the memory-based implementation of a binary-petri net

이진 페트리 네트의 메모리-베이스 구현을 기본으로 하는 프로그래머블 제어기에 관한 연구

For a fast evolution, a memory-based implementation of a petri net is discussed. A sub-class petri net model called B-petri net is suggested to make a memory-based implementation feasible in a large size application. The suggested B-petri net is a binary-petri net since only a binary-typed decision, fork and join are allowed. The application of a B-petri nt is focused to a SFC(sequential function chart) program. The memory requirement, speed and computational load are compared with a petri net when they are implementated by a memory-based method.
