Architectural design patterns for logic control of manufacturing systems: The generalized device

Towards an abstraction layer for PLC programming using object-oriented features of IEC61131-3 applied to motion control

“…This additional level is provided through the use of inheritance and by generic devices (e.g. as suggested in [21]). However, the architecture described up to now is limited.…”

“…In software engineering, a design pattern is a general reusable solution to a commonly occurring problem within a given context in software design. Faldella et al [16] proposed an architectural design pattern based to abstract control through the Generalized Device (GD). The GD is a new software component that abstractly model by means of a standardized FSM, the behavior of several field devices commonly used in automated systems, regardless of their nature, intrinsic features, and specific functional purposes.…”

Modularisierung von Steuerungssoftware

“…Die Widerstände werden vereinzelt, der Widerstandswert gemessen und basierend auf dem Messergebnis in eine der beiden Ablagepaletten eingelegt. Folgt man gängigen Methoden zur Hierarchisierung von Automationssystemen [10][11][12] Durch diese Methode können die überlagerten Komponenten, welche meist nur allgemeine Abläufe modellieren, von den spezifischen HW-Komponenten entkoppelt werden und somit die Wiederverwendbarkeit der beteiligen HW-und SW-Komponenten erhöhen. stimmung des Endes der Abarbeitung und der damit einhergehenden Aktualisierung der Ausgänge verwendet.…”

Distributed control patterns for intelligent mechatronic systems

“…It is therefore vital that software designers define suitable design patterns that concentrate on "cross-cutting control logic functionalities and suitably abstracting from application specific details" [8] which will make the design of complex automated systems easier and faster for engineers and practitioners. In fact, the ideal case would be to have intelligent software components that have most of their functionalities "pre-automated by the vendors" [9] and users can conveniently tailor them to their particular application with the least integration effort.…”
