2 Time Series Database Function
2-1

Function Overview

The Time Series Database Function allows you to save user-specified variables and calculation re-
sults of the Feature Value/Machine Learning Function into the storage of the AI Controller. Collected
data is first saved in a database called TimeSeries and then saved in the storage. High-speed data
recording was made possible by installing a database functionality inside the AI Controller. The opera-
tion of saving data into TimeSeries is referred to as "sampling", and the operation of saving data from
TimeSeries to the storage is referred to as "export".
