Summary: A method is presented for modeling, verification and automatic programming of PLC controllers. The method offers a formal model of requirements, the means for defining and verifying safe behavior, and a technique for generating program code. The modeling language is UML state machine, which provides a widely accepted means for writing a specification at a suitable high level of abstraction. Such an abstract specification can be validated by the user, verified by means of a model-checker and translated automatically into a program code, which preserves the correctness and safety of the specification. The program code is written in one of the standardized IEC 61131 languages.
