- Title:
- Reengineering Workflow for Planned Reuse of IEC 61131-3 Legacy Software
- Abstract:
- In automated production systems, an increasing proportion of functionality is implemented by control software. However, currently most companies do not implement variant and version management for their control software and, thus, lack a global knowledge base on existing software variants and versions. Further, despite its known drawbacks, i.e. poor maintainability, the reuse strategy copy, paste & modify is commonly applied, leading to an even higher amount of unmanaged, historically grown software variants and versions. Since this resulting control software contains a vast amount of essential domain knowledge, strategies for its planned reuse are required. Therefore, this paper presents a workflow to enable the transfer from copy, paste & modify to planned reuse by analyzing the historically grown control software variants and deriving reusable library modules from them. For the library module development from multiple sources, an interaction concept is proposed, which has been evaluated partially through a prototypical implementation.
