The Honeywell DNP3 History backfill functionality CV-IDNPHB is a specialized licensed option that provides critical DNP3 History Backfill functionality for industrial control systems, operating as an addition to the base PlantCruise software. This powerful feature is designed to automatically recover historical data following a communication outage between a master station and remote field devices. The technical capabilities of the History Backfill CV-IDNPHB Honeywell are significant, supporting requests for up to 10,000 data points per backfill operation with a rapid recovery speed of 500 points per second. This ensures that data gaps are minimized and system historians maintain a complete record, which is vital for accurate reporting and analysis.

A key specification of the Honeywell CV-IDNPHB History Backfill is its ability to handle maximum gap durations of up to 72 hours, making it robust enough for extended network or power failures. The data integrity is ensured through CRC-32 validation, and the time precision of ±10 milliseconds for timestamp alignment guarantees that all recovered data is accurately sequenced within the historical timeline. This precise engineering makes the Honeywell CV-IDNPHB an essential component for SCADA interfaces and data exchange where reliability is paramount.

The functionality provided by the PlantCruise DNP3 History Backfill CV-IDNPHB Honeywell is a licensed interface that falls under industry-standard communication options, complementing other protocols like OPC. It represents a software license combined with a runtime service, highlighting its role as an advanced, value-added feature rather than a standard inclusion. By seamlessly restoring lost process information, it enhances overall operational intelligence and ensures data continuity across the automation infrastructure.

In summary, the primary role of the CV-IDNPHB HONEYWELL is to safeguard data integrity within a DNP3 network. Its high-performance backfill capabilities prevent the permanent loss of critical process information during communication interruptions. The implementation of it is therefore a best practice for maintaining a complete and accurate historical database, supporting both operational efficiency and regulatory compliance in demanding industrial environments.
