Boosting Extra-Functional Code Reusability in Cyber-Physical Production Systems: The Error Handling Case Study

Cyber-Physical Production Systems (CPPS) are long-living and mechatronic systems, which include mechanics, electrics/electronics software. The interdisciplinary nature combined with challenges trends in the context of Industry 4.0 such as a high degree customization, small lot sizes evolution cause amount variability. Mastering variability functional control software, e.g., different variants an actuator type, is itself challenge developing reusing CPPS This task becomes even more complex when considering extra-functional software operating modes, diagnosis error handling. These parts have interdependencies often involving human-machine interface (HMI) to enable intervention operators. paper illustrates documenting dependencies these including their using family models. A procedural object-oriented concept for implementing handling, represents HMI, proposed. suitability both concepts increase software's reusability and, thus, its flexibility discussed. Their comparison confirms potential extension IEC 61131-3 handle planned reuse successfully.
