Considerations for Integrating Historian Tools and Industrial Human Machine Interface (HMI)
Operations personnel who work in industrial facilities often find it difficult to access the detailed data they need to solve important process problems. Operators with access to real-time data streaming in from control and automation systems often struggle to understand the problems they are observing. Tools called historians address these issues by providing a complete process history for enhanced troubleshooting and analysis. This paper reviews the benefits of integrating historians with Human Machine Interface (HMI) applications that help control key industrial processes.
