ChronoCoreOne historian for every signal, every source
ChronoCore

ChronoCore — the EPSILON historian — ingests, compresses and stores high-fidelity time-series data from DCS, SCADA, PLC and IoT sensors — creating a single source of truth for the entire enterprise.
Every downstream module reads from the same store, so a trend in TwinCore, a virtual tag in NexusTM and a prediction from AI Brain are always looking at the same numbers. Ingest once, use everywhere.
Universal connectivity
Native drivers for DCS, SCADA, PLC and IoT protocols, with store-and-forward buffering so no data is ever lost.
Lossless compression
Advanced compression cuts storage requirements dramatically without sacrificing signal fidelity.
Massive scalability
Scales from a single site to millions of tags across a tiered, global historian architecture.
Built-in resilience
Automatic backfill, redundancy and disaster recovery keep data flowing, even through network outages.
