These frequently use visual programming languages based on standards such as IEC 61131-3 and 61499. The apply model-based engineering concepts to abstract from hardware low-level communication. Developing industrial is challenging due the fact that systems one-of-a-kind have be maintained for many years. challenges, together with growing complexity software, require very usable development...

A Grafcet is a standardized model for describing the behavior of systems which popular among automation engineers. As standard excludes implementation details, models are typically translated to software. Such software was traditionally programmed in one languages specified IEC 61131-3. Nowadays, increasingly modelled 61499 facilitates designing distributed control systems. In this paper, we define translation methodology, so that engineers can benefit from advantages while continuing use...

Component-based software engineering has emerged as a principle of design to facilitate reuse and improve the quality. This is supported by domain-specific language IEC 61499, where Function Blocks are fully encapsulated components. For Block definition, static interface description an internal implementation required. Service sequences describe event flow at component optional dynamic model in 61499. In general, models powerful tool for various use cases, yet service rarely used practice...

Refactoring is a key technology for improving the quality of software system. A higher will lead to clearer structure, which facilitates sharing work across multiple teams. This important especially in domain cyber-physical production systems, where different engineering disciplines meet at their cutting point. IEC 61499 tries abstract increasing complexity such systems. gives an overview existing refactoring techniques from and provides first insight on how apply

The IEC 61499 standard defines a model for distributed control systems based on function blocks (FBs) and event-driven execution. Although interoperability portability between tools are core goals of the standard, behavior an executable varies significantly run-time environments (RTEs). This presents challenges comparing execution traces, e.g., when validating that simulation conforms to specific RTE. In this paper, we propose methodology analyzing custom RTEs example models cover language...

Accurate flow measurement is a ubiquitous task in fields such as industry, medical technology, or chemistry; it remains however challenging due to small ranges erosive flows. Inspiration for possible methods can come from nature, example the lateral line organ of fish, which comprised hair cells embedded gelatinous cupula. When cupula deflected by water movement, generate neural signals fish gains an accurate representation its environment. We built sensor mimicking cell, but coupled with...

Industrial standards define domain-specific languages that are frequently used for developing control software. For instance, IEC 61499 standardizes a graphical modeling language includes platform-independent application model. The is composed of Function Blocks. A runtime can execute the model by implementing semantics described in standard natural language. By defining an interpreter models, we directly them without prior code generation. This enables providing feedback on level. We...

Model-based software engineering is a promising approach for controlling complex automation systems. Automation engineers, unfortunately, do not routinely model the expected behavior, especially if they are trained in engineering. They rather focus only on implementation.

Consumer electronics are getting both smaller and more powerful. Hence, there is a need for small, scalable, silent, reliable low-cost cooling systems. In order to meet these requirements, we designed simple synthetic jet (SynJet) actuators using silicone elastomer membranes together with either soft composite or rigid neodymium magnets. The SynJet were electromechanically driven near their mechanical resonance frequency in the low-frequency range between 5 Hz 120 Hz. compare configurations,...
