We give timed automaton models for a class of Pro- grammable Logic Controller (PLC) applications, that are programmed in a simple fragment of the language Instruc- tion Lists as defined in the standard IEC 1131-3. Two dif- ferent approaches for modelling timers are suggested, that lead to two different timed automaton models. The purpose of this work is to provide a basis for verificationand testing of real-time properties of PLC applications. Our work can be seen in broader context: it is a contributionto methodi- cal development of provably correct programs. Even if the present PLC hardware will be substituted by e.g. Personal Computers,withasimilaroperationmode, thedevelopment and verification method will remain useful. |
