This paper proposes some elements of such a model. Elements of IEC 61499 architecture are defined in a formal way following set theory notation. Based on this description, formal semantics of IEC 61499 can be defined. An example is shown in this paper for execution of basic function blocks. The paper also provides a solution for flattening hierarchical function block networks. SN - 1687-3963 UR - https://doi.org/10.1155/2008/426713 DO - 10.1155/2008/426713 ID - Dubinin2007 ER -
