In: 2018 IEEE 23RD INTERNATIONAL CONFERENCE ON EMERGING TECHNOLOGIES AND FACTORY AUTOMATION (ETFA). - Piscataway, NJ : IEEE. - 9781538671085 ; , s. 147-154
-
Conference paper (peer-reviewed)abstract
- This paper proposes a novel extension for communication in the IEC 61499 standard. Inspired by the features found in the formal programming language SystemJ, the extension supports reliable and guaranteed communication in distributed execution of function block application(s)/program(s). The extension utilizes mechanisms agnostic on underlying network protocols and are based on formal semantics that guarantee data delivery. The use of proposed extension, called channel, is demonstrated in an industrial automation-type example.

A Service-Oriented Programming Approach for Dynamic Distributed Manufacturing Systems
- 2020
-
In: IEEE Transactions on Industrial Informatics. - : IEEE. - 1551-3203 .- 1941-0050. ; 16:1, s. 150-160

Journal article (peer-reviewed)abstract
- Dynamic reconfigurability and adaptability are crucial features of the future manufacturing systems that must be supported by adequate software technologies. Currently, they are typically achieved as add-ons to existing software tools and run-time systems, which are not based on any formal foundation such as formal model of computation (MoC). This paper presents the new programming paradigm of Service Oriented SystemJ (SOSJ), which targets dynamic distributed software systems suited for future manufacturing applications. SOSJ is built on a merger and the synergies of two programming concepts of (1) Service Oriented Architecture (SOA), to support dynamic software system composition, and (2) SystemJ programming language based on a formal MoC, which targets correct by construction design of static distributed software systems. The resulting programming paradigm allows the design and implementation of dynamic distributed software systems.

Towards Industrial Internet of Things : An Efficient and Interoperable Communication Framework
- 2015
-
In: 2015 IEEE International Conference on Industrial Technology, ICIT 2015. - Piscataway, NJ : IEEE Communications Society. - 9781479978007 ; , s. 2198-2204
-
Conference paper (peer-reviewed)abstract
- Interoperability between shop floor devices and upper layer systems is a key challenge for enabling Internet of Things in industrial applications. Standardized protocols such as IPv6, CoAP, and XML can be used to address this issue. Widely used XML-based technologies such as SenML, EEML, OPC-UA as well as others rely on XML to be able to support a wide range of sensor and actuator applications. However, this approach results in high communication overhead due to the verbose nature of plain text messages encoded in XML. When devices are communicating using 6LoWPAN over IEEE 802.15.4, it is important to keep the messages small enough to fit into one MAC-layer frame to avoid fragmentation and hence conserving bandwidth and transmission energy. One possible solution is to integrate differential binary delta-encoding with a service-based framework based on CoAP, SenML and EXI. The proposed efficient communication approach for service-based architecture can compress a series of events up to 90-95%. The proposed framework is a holistic approach for enabling distributed monitoring and control applications and a move towards realizing the vision of Services of Things.

The SystemJ approach to system-level design
- 2006
-
In: [Host publication title missing]. - 1424404215 ; , s. 149-158
-
Conference paper (peer-reviewed)abstract
- In this paper, we propose a new system-level design language, called SystemJ. It extends Java with synchronous reactive features present in Esterel and asynchronous constructs suitable for modelling globally asynchronous locally synchronous systems. The strength of SystemJ comes from its ability to offer the data processing and encapsulation elegance of Java, Esterel-like reactivity and synchrony, and the asynchronous de-coupling of CSP all within the Java framework. Using standard Java environments, for specification and modelling, or specialised reactive embedded processors, for high performance implementation, the SystemJ design flow is extremely versatile. With the increasing attention that Java gets in embedded systems, SystemJ comes to address data and control, software and hardware, modelling and implementation in a unified manner.

Model-based customisation of intelligent mechatronic systems using SysML
- 2013
-
In: Proceedings of 2013 IEEE 18th International Conference on Emerging Technologies & Factory Automation (ETFA 2013). - Piscataway, NJ : IEEE Communications Society. - 9781479908622
-
Conference paper (peer-reviewed)abstract
- This paper presents a model-based design approach for description of mechatronic systems using System Modeling Language (SysML) in order to facilitate modification and customization of existing intelligent mechatronic components and their use in new applications. This approach enables re-use and integration of the existing mechatronic software components to meet system design requirements and minimize the design and commissioning complexity of the control systems. A case study with a delta robot used in a colour sorting application demonstrates how its control system is tailored to meet the desired system behaviour

Competitors or Cousins? : Studying the Parallels between Distributed Programming Languages SystemJ and IEC61499
- 2014
-
In: Proceedings of 2014 IEEE 19th International Conference on Emerging Technologies & Factory Automation (ETFA 2014). - Piscataway, NJ : IEEE Communications Society. - 9781612849690 ; , s. 1-7
-
Conference paper (peer-reviewed)abstract
- We face a glut of languages for programming distributed software today. However, only a few languages have proven their potential with wider practical use in different domains of computing. We picked two such languages, meant for different domains, to see if they could cross-pollinate and enrich one another. Specifically, we chose SystemJ, a language to program distributed embedded systems, and IEC61499, the next generation standard for distributed industrial automation control software. Unsurprisingly, we found similar structures and artifacts between the two. We also found significant differences mainly due to differing domain-specific requirements. This comparison leads to observations and guidelines for improving both languages, and we discuss directions towards an “ideal” distributed software programming language.

MIRA : Enabler of Mass Customization through Agent-Based Development of Intelligent Manufacturing Systems
- 2014
-
In: 2014 IEEE International Conference on Robotics & Automation (ICRA). - Piscataway, NJ : IEEE Communications Society. - 9781479936854 ; , s. 258-263
-
Conference paper (peer-reviewed)abstract
- This research proposes an innovative agent-based design method known as “MIRA” (Modular, Intelligent and Real-time Agent) to represent products as well as mechatronic components in manufacturing systems. The new agent exploits semantic knowledge representation of its capabilities, tasks and surroundings, and upon which performs rule-based reasoning leading to generation of the IEC 61499 Function Blocks for real time and distributed control of production systems. This approach facilitates product's mass customization through development of intelligent mechatronic systems. Furthermore, the MIRA approach is exemplified in a food production case study.

Software Composition and Distributed Operation Scheduling in Modular Automated Machines
- 2015
-
In: IEEE Transactions on Industrial Informatics. - 1551-3203 .- 1941-0050. ; 11:4, s. 865-878
-
Journal article (peer-reviewed)abstract
- This paper proposes a new software composition method for automated machines that exploits their mechatronic modularity. It is demonstrated that desired behavior of a certain class of machines can be composed of behaviors of its mechatronic components, including fully decentralized scheduling and operation control. This aims at increased performance of software design and maintenance, as well as systems' flexibility and reconfigurability. The IEC 61499 Function Blocks' (FBs) architecture is used as an implementation platform that enables system-level simulation and transparency of deployment. A configurable pick-and-place (PnP) manipulator with decentralized control synthesized using the proposed approach is chosen as an illustrative example

Now that's smart!
- 2007
-
In: IEEE Industrial Electronics Magazine. - 1932-4529 .- 1941-0115. ; 1:4, s. 17-29
-
Journal article (peer-reviewed)abstract
- In order to encapsulate knowledge into function blocks, have more configurability of devices and features and apply models as a network of function blocks, the function block architecture of IEC 61499 has bee developed. IEC 61499 provides a new degree of flexibility in managing embedded control and information processing systems. IEC 61499 can also be used in a network of function blocks wherein an application is distributed across different computing devices. IEC 61499 provides a mechanism for creating new device types as a set of resource types and function block libraries and uses an Open XML-based device management protocol, which in turn enables configurability of compliant devices by compliant software tools. As such, IEC 61499 is a far better solution that existing PLC systems, not to mention the fact that it allows creation and deletion of resources which are containers for applications. IEC 61499 function blocks have enabled features such as reconfigurability, PnP, independence of target execution platforms and independence of control strategy.
