Using vernacular from the industrial automation industry, how is this different from a historian?

A sensor is physically wired to an input on a PLC which collects data, the historian software communicates with the PLC/DCS and saves instrument/sensor data for further review.

Based on my understanding of historians, we combine a historian, real-time data visualizer/processor, and hardware controller into one. We tried to create a more unified and developer-friendly ecosystem - reducing the need for multiple disparate components and adapters and abstracting out the low-level work necessary to interface with hardware like PLCs.
