Best practices for historian modernization
Historians acquire real-time data from programmable logic controllers (PLCs), sensors, and other automation systems to store time-series data at high speed while maintaining data quality. Data from on-site historians can be consolidated to a modernized enterprise historian in the cloud. The following are some best practices for planning a modernized historian approach for your organization:
-
Start by building a case study explaining why a modernize approach is required. Consider business drivers and industry challenges, such as advanced analytics, costs of on-premises data centralization, and multi-site visibility.
-
Historians can be expensive. Create a return on investment (ROI) analysis to justify the investment. Explain how historian modernization, in the long term, can reduce costs and provide returns.
-
Identify two or three business use cases that quickly show the value of implementing a modern historian approach.
-
Provide a configurable approach for hot and cold time-series data. Based on the access patterns and personas, clearly document how end users would interact with the system.
-
Integrate the cloud-based historian with any existing data stores to help drive advanced use cases, such as preventive maintenance, anomaly detection, and digital twins.
-
Build high availability and disaster recovery (HA/DR) into the architecture.
