In order to allow application of the proposed concept to existing PLCs, requirements of the predominant IEC 61131-3 suchdasd, sucycliccyclic execution, are taken into account.
In this paper, we propose a component-based formal modeling and synthesis method for cyclic execution platforms and apply it to PLC.
We further contribute transformation rules of semantically adapted UML sequence diagrams to the cyclic execution logic of PLCs for reactive systems.

In strong cyclic planning, all the executions associated with the solution plan always have a possibility of terminating and, when they do, they are guaranteed to achieve the goal.
The instructions are accessed in a cyclic manner that supports periodical execution of a set of operations.
We conclude that hierarchical relationships among the cleaning modules mediate not only their sequential execution, but also the cyclic transition dynamics between body cleaning and leg rubbing.
Necessary and sufficient conditions are given for the existence of a bounded cyclic schedule, as well as sufficient conditions for execution of the graph in bounded memory.
These are obtained by analyzing the properties of minimal cyclic schedules, defined as minimal sequences of actor executions that return the dataflow graph to its original state.
The main problem is in essence to identify conditions guaranteeing transient period free re-scheduling of cyclic steady state flows of multimodal processes and local transportation processes supporting their execution.
Our problem is also similar to a problem of mining cyclic association rules [11] where an objective is to find the periodic executions of the largest sets of items that have enough support.
During beat entrainment in the context of sensorimotor synchronization tasks, for instance, the corresponding tapping behavior has been shown to produce cyclic fluctuations in sensory gain that are locked to individual movements, suggesting that top-down signals linked to rhythmic motor execution may tune representations of incoming sensory information36,37,38.
