As well as reliable alarm mechanisms, periodic sensor reporting is vital to maintain confidence in a computerized system. Notably, monthly reports have to comply with ISO standards for long-term data archives.
Similarly, combined weekly reports for customers provide concise overviews for each project concerned. In contrast, daily reports are ideal for automated batch runs and quality control.
How is data archived?
Although not explicitly defined in GxP regulations, archiving involves moving non-active data to a separate storage device. It is essential to retain these archives for future access, perhaps for regulatory or compliance reasons. Archived information may be in a different form from process data.
Also called fresh data, process data is instrumental in decision-making. Product detail and temperature measurements must be available electronically for at least two years for visualizations, reports, exports, and statistics such as MKT (mean kinetic temperature) calculations.
After two years, service providers can archive these files in secure storage. The electronic archives must remain available for at least ten years. Archive files should bear clear, self-explanatory names and be in a readable format such as PDF/A, which meets ISO 19005 standards.
Why are Dashboards Important?
In temperature control system installations, display dashboards provide concise overviews of temperature sensors, meaningfully grouped by location. Characteristically, screens display the current conditions, warning alarms, and each sensing device's technical status to facilitate monitoring.
