VHDL architecture for IEC 61499 function blocks
IET Computers and 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).

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.

fbSAT: Automatic Inference of Minimal Finite-State Models of Function Blocks Using SAT Solver
IEEE Access, 2022 Finite-state models are widely used in software engineering, especially in the development of control systems. In control applications, such models are often developed manually, which can make it difficult to keep them up to date.

Towards IEC 61499 function blocks diagrams verification [PDF]
IEEE International Conference on Systems, Man and Cybernetics, 2003 After having sketched the different techniques enabling to check properties of Discrete Event Systems control software, we present in this article a formal method for IEC 61499 function blocks diagrams verification. This method is based on a formal representation of the behaviour of function blocks diagrams and takes benefit of verification tools ...

A Software Measure for IEC 61499 Basic Function Blocks
2020 25th IEEE International Conference on Emerging Technologies and Factory Automation (ETFA), 2020 When proposing new design patterns or design guidelines for IEC 61499 Applications, their performance and quality has to be compared to alternative solutions. Software measures are a way of achieving that. Although first attempts towards software measures for IEC 61499 were made, the standard still lacks a solid set of measures to evaluate applications.

Enabling data-driven anomaly detection by design in cyber-physical production systems
Cybersecurity, 2022 Designing and developing distributed cyber-physical production systems (CPPS) is a time-consuming, complex, and error-prone process. These systems are typically heterogeneous, i.e., they consist of multiple components implemented with different languages

Komparasi Protokol Komunikasi pada Sistem Produksi Siber-Fisik berbasis IEC 61499
Jurnal EECCIS (Electrics, Electronics, Communications, Controls, Informatics, Systems), 2020 The change in the concept of an automation pyramid into an automation cloud in a cyber-physical production system makes data communication no longer stratified but can be done directly between devices.
