SCADApõhist

SCADApõhist is a theoretical framework that merges supervisory control and data acquisition systems with historiographical practice. It treats SCADA data not only as a source for real-time monitoring but as evidence for historical analysis, enabling time-aware reconstructions of how industrial processes were operated, optimized, and transformed over decades. The name signals the fusion of control-system engineering and historical interpretation.

Developed in academic and heritage contexts, SCADApõhist aims to document industrial evolution, support experimental archaeology of infrastructure, and provide educators with narratives grounded in sensor data. It is intended as an adjunct to operational control, not a substitute for reliability and safety monitoring.

Architecturally, SCADApõhist comprises four layers: a data layer that collects real-time streams and archived logs from SCADA networks; a metadata and provenance layer to describe sources, instrumentation, and data quality; an analysis layer that applies historiographic methods such as event sequencing, causality inference, and pattern analysis; and a presentation layer that generates timelines, visualizations, and narrative reports for researchers and the public.

Applications span industrial archaeology, factory and grid history, preservation planning for heritage sites, and educational programs that illustrate the evolution of automation. Case studies may reconstruct production lines, energy flows, and maintenance practices to illuminate technological and social change.

Challenges include data accessibility and interoperability, varying data quality, cybersecurity and safety restrictions, and the risk of over-interpretation. Effective use requires transparent provenance, clear documentation of assumptions, and collaboration between historians, engineers, and information security professionals.
