Towards a Formal Semantic Model of IEC 61499 Function Blocks [PDF]
2006 IEEE International Conference on Industrial Informatics, 2006 This paper proposes a formal model of IEC 61499 function blocks and systems. The model is intended to be used in description of formal semantic model of function blocks' execution. The paper outlines a number of challenges for function blocks that are supposed to be answered by the proposed model.

On Definition of a Formal Model for IEC 61499 Function Blocks [PDF]
EURASIP Journal on Embedded Systems, 2008 Formal model of IEC 61499 syntax and its unambiguous execution semantics are important for adoption of this international standard in industry. This paper proposes some elements of such a model. Elements of IEC 61499 architecture are defined in a formal way following set theory notation.

A Graphical Programming Language and Its Supporting Tool for Insect Intelligent Building
Scientific Programming, Volume 2020, Issue 1, 2020., 2020 The emerging Insect Intelligent Building (I2B) platform is pioneering a new realm in intelligent buildings. I2B has a distributed and decentralized network structure with intelligent nodes, and the key enabler is an application (APP) that functions to process information from intelligent nodes and accomplish complex control tasks in a decentralized ...

VHDL architecture for IEC 61499 function blocks
IET Computers & Digital Techniques, 2010 IEC 61499 runtime systems to-date have focussed on software implementations deployed to various micro-processors. This study proposes a novel and viable architecture allowing IEC 61499 models to be deployed as custom logic within a field programmable gate arrays (FPGAs).

Complexity of Structured Text in IEC 61499 Function Blocks: A Survey.
2023 IEEE 28th International Conference on Emerging Technologies and Factory Automation (ETFA), 2023 The rising complexity of modern production systems raises the need for evaluating the code quality also in control software engineering. Complexity metrics can help identifying code that is difficult to maintain and may benefit from a refactoring. Although complexity metrics have already been adapted to the domain-specific languages (DSLs) used for ...
