摘要
PLC-Automata are a class of real-time automata suitable to describe the behavior of polling real-time systems. PLC-Automata can be compiled to source code for PLCs, a hardware widely used in industry to control processes. Also, PLC-Automata have been equipped with a logical and operational semantics, using Duration Calculus (DC) and Timed Automata (TA), respectively. The three main results of this paper are: (1) A simplified operational semantics. (2) A minor extension of the logical semantics, and a proof that this semantics is complete relative to our operational semantics. This means that if an observable satisfies all formulas of the DC semantics, then it can also be generated by the TA semantics. (3) A proof that the logical semantics is sound relative to our operational semantics. This means that each observable that is accepted by the TA semantics constitutes a model for all formulas of the DC semantics.
