A method of performing an interactive procedure with a portable smart device utilizes assets that include asset identifiers in an industrial facility. The method provides indicia and/or photographs on a display of the portable smart device for procedural steps of a procedure to be performed on an industrial facility. The portable smart device receives an input to begin the procedure, displays indicia and/or photographs of an asset location and a first procedural step for an asset having an asset identifier. The portable smart device scans an asset identifier to ensure the proper asset is located. Thereafter, a procedural step for the asset is displayed. Upon performance of the step, an operator provides a confirmation to the smart device for ensuring that the procedural step is performed.

Die Erfindung betrifft ein Verfahren zur Simulation einer automatisierten industriellen Anlage mit einer speicherprogrammierbaren Steuerung (11, 21, 30), in welcher ein Automatisierungsprogramm (33) und ein Simulationsprogramm (37) zur Simulation des Anlagenverhaltens anhand eines in der speicherprogrammierbaren Steuerung (11, 21, 30) hinterlegten Anlagenmodells oder Anlagenteilmodells (40) ablaufen. Prozesssignale, die beim realen Betrieb zur Ubertragung uber eine Prozessschnittstelle (13, 23, 32) zwischen Automatisierungsprogramm (33) und Anlage vorgesehen sind, werden bei der Simulation der automatisierten industriellen Anlage zwischen Automatisierungsprogramm (33) und Simulationsprogramm (37) ubertragen. Dadurch kann der Aufwand, der bei bisherigen Simulationswerkzeugen fur die Ankopplung an die Prozessschnittstelle (13, 23, 32) erforderlich war, nun vorteilhaft entfallen.

The invention provides a method and a device for generating a production process semantic model. The method comprises the following steps: collecting event data acquired by an event data acquisition point in a production process, wherein the event data reflects the state change of production elements in the production process; getting context information related to the acquired event data from a context information base; and based on the acquired event data and the context information related to the acquired event data, connecting production elements involved in the acquired event data into a production process semantic model through semantic relations. Through the method and the device, the efficiency of production process semantic model generation is improved.

The dependability characteristic of the control software of manufacturing systems is highlighted more than before, going through repeated changes to cope with various and varying requirements. Formal methods are researched to be applied to automation system engineering to obtain a more effective and efficient quality assurance. One of the approaches, a formal specification language named Generalised Test Tables has been developed with the aim of intuitiveness and accessibility for automation application developers. The result of the experiments conducted to assess the usability of this language is presented here. Focussing on evaluating effectiveness and user satisfaction, three paper-based experiments have been conducted with students at the bachelor and master level. The evaluation results point to positive usability in both comparative effectiveness to conventional language, that is, Petri Nets, and subjective perception of user satisfaction.

GRAFCET is a powerful graphical modelling language and an international standard to specify the behavior of discrete event systems. One of the main advantages of GRAFCET compared to other specification languages is the description of distributed and nested program parts within a control application based on the hierarchical structures enclosing steps, partial-Grafcet and forcing orders. This contribution presents a meta-model based approach for GRAFCET specifications, including hierarchical structures. For this purpose, a suitable static GRAFCET meta-model has been defined. This model is the basis for both, a model-driven implementation of a graphical editor as well as a model-based GRAFCET syntax verification. This meta-model based approach has been made in consideration of the benefits of MDSD and the potential to expand the solution to other issues of formal methods in control system engineering. An integrated software solution is presented using the open-source environment Eclipse.
