Explanation

A local historian is a system specifically designed to store and manage large volumes of time- series data, such as the tag data generated by programmable logic controllers (PLCs) in industrial environments. This data typically includes sensor readings, system states, and other operational data. A historian collects, stores, and organizes this data locally, making it available for data analysis, visualization, and predictive maintenance.
