Why AVEVA Historian?
For current Citect Historian users, migrating to a modern and scalable solution like AVEVA Historian can bring several advantages. If your operation is evolving towards Industry 4.0, cloud connectivity, or enterprise-wide data management, AVEVA Historian provides a more future-proof platform.
Key benefits of AVEVA Historian include:
- With support for tag counts in the millions, AVEVA Historian is designed to scale from small plants to large enterprise-wide operations. This scalability ensures that as your data grows, whether from increased sensor counts or expanded operational scope, the historian handles vast amounts of time-series data efficiently.
- The hybrid design supports the fast, reliable real-time data collection by the on-site Tier-1 historian. The Tier-2 historian aggregates data enterprise-wide, enabling centralized reporting, dashboards, and KPIs. This two-level approach eliminates the need for costly custom integrations and lowers overall system maintenance costs compared to Citect Historian’s single-tier architecture.
- AVEVA Historian collects data from any sensor, driver, or protocol across existing operational technology networks and new Industrial Internet of Things (IIoT) devices. Through AVEVA Connect, users gain secure access to AVEVA Insight, the cloud-based information management portal and mobile app, enabling them to remotely monitor and analyze real-time data from any location.

Migrating from Citect Historian to AVEVA Historian can vary widely in complexity depending on how the current system is used and integrated. If your Citect Historian environment is relatively simple—primarily used to view historical data collected from Citect SCADA—then the migration tends to be straightforward. This often involves mapping tags, exporting and importing historical data, and configuring AVEVA Historian to collect live data similarly.
However, when the Citect Historian integrates with multiple other systems, the evolution to AVEVA Historian becomes trickier. This complexity arises because several dependent systems and interfaces may require reconfiguration, migration, or redevelopment to work with AVEVA Historian instead of Citect Historian. The list below outlines key systems and factors that typically need attention during migration:
- Reporting (Dream Report, SSRS, etc.)
- CMMS
- GIS
- SCADA trend screens
- SCADA alarm screens
- Network segregation (DMZ)
- MES systems (AVEVA Production Management, etc.)
- Historical data retention
Due to this complexity, particularly when multiple systems interact with the historian, engaging experts who understand both Citect and AVEVA Historian platforms is essential. In addition, these experts should have experience with the other systems listed above to ensure smooth transitions, minimize downtime, and maintain data integrity.
