Analyzing the liveliness of IEC 61499 function blocks
2008 IEEE International Conference on Emerging Technologies and Factory Automation, 2008This paper aims at the systematic determination of faulty and problematic execution control charts (ECC) of IEC 61499 basic function blocks. The liveliness of a function block and the potential state transitions fundamentally depend on the execution semantics of function blocks.

Verifying IEC 61499 Function Blocks Using Esterel
IEEE Embedded Systems Letters, 2010IEC 61499 is an international standard that prescribes the use of function blocks for designing industrial-process control systems. Function blocks enable control software to be developed using an intuitive standard's-based graphical framework. The standard, however, lacks the semantic rigour necessary for automated verification of function block ...

Hierarchical and Concurrent ECCs for IEC 61499 Function Blocks
IEEE Transactions on Industrial Informatics, 2016IEC 61499 enables component-oriented descriptions of complex industrial processes facilitating model-driven engineering. One aspect that is lacking, however, is the ability to directly express Statecharts-like hierarchy and concurrency within basic function blocks (BFBs).

Reconfigurable function blocks: Extension to the standard IEC 61499
2016 IEEE/ACS 13th International Conference of Computer Systems and Applications (AICCSA), 2016This paper presents an extension to the IEC 61499 standard called Reconfigurable Function Block. The major goal is to optimize the design of a network of Function Blocks by encapsulating several reconfiguration scenarios in one function block. We define the events triggering the reconfiguration and we attach a probability to each event to express its ...

Integrating CNet and IEC 61499 function blocks
2007 IEEE Conference on Emerging Technologies & Factory Automation (EFTA 2007), 2007CNet and IEC 61499 function blocks both have been defined for designing modular, concurrent and distributed control systems. CNet components as well as IEC 61499 function blocks allow modularization and hierarchization. Both concepts describe system behavior in an event-discrete manner.

Observer based verification of IEC 61499 function blocks
IEC 61499 is an international standard for designing Industrial Process Control Systems using artefacts such as Function Blocks and Execution Control Charts. The existing approaches towards formal verification of function blocks lack the natural expression for specifying the system properties.

Synchronous Execution of IEC 61499 Function Blocks Using Esterel
The IEC 61499 standard proposes a component-oriented approach for specifying industrial-process measurement and control systems using function blocks. Unfortunately, the standard does not provide rigorous semantics for the execution of function blocks, resulting in different behaviours on different implementations.

A case study on migration from IEC 61131 PLC to IEC 61499 function block control
The IEC 61499 architecture is a new standard proposed to replace current PLC technologies. This paper aims to develop a guide to migrate from IEC 61131 PLC technologies to IEC 61499 function blocks, especially for PLC programmers. Multiple PLC platforms are chosen as examples and transformed function block system is provided.

Synthesizing IEC 61499 Function Blocks to hardware
2019 International Conference on Electronics, Information, and Communication (ICEIC), 2019IEC 61499 Function Blocks is the emerging standard for distributed control of industrial automation systems. Within this domain, it is common for devices to need robust timing and functional guarantees. Unfortunately, many industry-standard approaches can only provide analysis for functional correctness.
