Engineering of industrial production systems using AML

1

AutomationML (AML) is a standard for tool data exchange= domain = tool = doc

Industry 4.0

“IEC 62714 - Engineering data exchange format for use in industrial automation systems engineering - AutomationML”, www.iec.ch, International Electrotechnical Commission, 2014.

Challenges in parallel multi-disciplinary Engineering

2

1. Tool networks do not ensure sufficient data consistency.

2. Data cannot be queried using an uniform interface.

3. Tool networks do not make data easily and efficiently accessible on project level, e.g., for risk management, test automation or observation of project progress.

Evaluation with a Lab-Sized Plant at Uni Magdeburg

Lab-sized Production System“Equipment Center for Distributed Systems,” http://www.iafbg.ovgu.de/en/technische ausstattung cvs.html, Institute of Ergonomics, Manufacturing Systems and Automation at Otto-v.-Guericke University Magdeburg, [Online; accessed 11-May-2015].

• RQ1 Roundtrip capabilites• Are transformations between

AML XML and AML models possible without loss of information?

• Result: All reference examples and real world examples could be transformed to AML models and back to AML XML without loss of information

• RQ2 Integration capabilites• Is the linking language expressive

enough for practical settings?• Result: All mappings of a lab-sized

production system (picture to the right) could be modeled

Capabilities of the Model-Driven Approach

9

1. Re-use of established Model-Driven Techniques (e.g. Code-Generation, Model-Validation, Model-Transformations,…)

2. Queries on models with the Object Constraint Language (OCL)a. Show all elements of a specific type (e.g. sensors)b. What is the energy consumption of the plant?c. Show all parts that have reached their maximum working hours

3. Reasoning for consistency checkinga. Are there any broken links within the project?

b. Is there a newer component available?

Conclusion and Outlook

• The AML Hub allows data integration of multi-disciplinary engineering artefacts• Model Driven Approach was effective and efficient to provide a software tool

prototype with Linking and Versioning capabilities• The feasibility of the approach was shown in a real world case study

• Outlook: Risk management based on advanced reasoning

• We will be happy to demonstrate the tool prototype an answer your questions after the talk
