Event Storms in IEC 61499 Applications
2018 Conference on Design of Circuits and Integrated Systems (DCIS), 2018The event-based IEC 61499 standard was established to complement the cycle-based IEC 61131 standard for PLC applications. It focuses on the design of an application employing a function block based approach, whereas the implementation targeting either standalone or networked embedded systems is kept transparent.

Fault injection for IEC 61499 applications
2016 IEEE 21st International Conference on Emerging Technologies and Factory Automation (ETFA), 2016Distributed control systems relying on IEC 61499 are a common engineering approach for various application domains ranging from industrial control to the management and control of modern buildings. In this paper we propose a generic fault-injection concept to support the verification of applications.

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).

Extension of reconfigurability provisions in IEC 61499
2013 IEEE 18th Conference on Emerging Technologies & Factory Automation (ETFA), 2013This paper presents an investigation into the implementation of reconfigurable industrial applications using the IEC 61499 standard. An architecture and design methodology is proposed to allow for the addition of reconfigurable elements to existing IEC 61499 applications. The commercially available NxtForte IEC 61499 platform was chosen for experiments.

The IEC 61499 standard provides definition of various structures, such as systems, devices, resources, and various function block types, which allow for a component-oriented design of a program. This design approach resembles the famous object-oriented design paradigm, where the domain objects, e.g.

Is IEC 61499 in harmony with IEC 61131-3?
IEEE Industrial Electronics Magazine, 2009This year marks the 16th anniversary of the International Electrotechnical Commission (IEC) 1131-3 (now IEC 61131-3), currently one of the most important standards in industrial automation. Four years before its release, it has been decided that it will define a further standard for programming industrial control systems, the IEC 61499 standard.

Framework for management of replicated IEC 61499 applications
2008 IEEE International Conference on Emerging Technologies and Factory Automation, 2008The IEC 61499 standard defines function blocks with which distributed control applications may be developed, and how these are interpreted and executed. With the distributed nature of the control application, many issues also need to be taken into account.

The Past, Present, and Future of IEC 61499
2007In 1991, Technical Committee 65 (TC65) of the International Electrotechnical Commission (IEC) approved a New Work Item (NWI) for the development of an international standard for the use of software objects known as Function Blocks (FBs) in distributed Industrial-Process Measurement and Control Systems (dIPMCS).

A Schedulability Analysis of an IEC-61499 Control Application
IFAC Proceedings Volumes, 2005This paper deals with the temporal correctness of control applications designed using the component-based standard IEC 61499. In this standard, a function block is defined as an event trigger component containing its own data. To validate the temporal behavior of an application, we have to take into account its scheduling on the execution support.

Guaranteeing replica determinism on IEC 61499
Proceedings of the 2014 IEEE Emerging Technology and Factory Automation (ETFA), 2014Being distributed in nature, IEC 61499 industrial control applications are subject to partial failures. Building applications that are tolerant of these failures (i.e. a fault-tolerant application) may be achieved through the use of replication. In this paper we present a framework to support replicated IEC 61499 applications, and study how replica ...
