Abstract

Application specific integrated circuits Automatic control Control systems Error correction Fires Hardware Manufacturing automation Programmable control Programmable logic arrays Switches
Factory automation requires that programmable controllers should be very fast and easily designed and that their errors should be analyzed precisely during design and can be detected during operations. As the Petri net has a theoretical foundation, such as reachability tree analysis, it is suitable for the description and analysis of sequential control. This paper proposes an error checking hardware scheme for a Petri net sequence controller. The Petri net is very useful to represent parallel events and this controller has realized very high speed sequential control based on the Petri net graph.< >
