Scripting in Calculations | Factry Historian Training Video | Historian Calculations

This tutorial dives into scripting-based calculations in Factry Historian. It explains how you can use the built-in scripting engine to define custom metrics or logic on top of raw time series data — useful for calculating KPIs, aggregating batch-level insights, or running domain-specific rules. The video shows how to write and test scripts using Factry’s calculation editor, which supports Python-like syntax for flexible expressions.You’ll see examples such as calculating pressure drop over time, deriving average flow across a shift, or building custom rules based on quality thresholds. It also touches on debugging techniques and how to ensure scripts run correctly in both real-time and backfilled contexts.This functionality helps industrial teams automate insights, reduce Excel dependency, and create plant-specific metrics that reflect actual operations.
