SCADA Historian Optimization: Tag Compression, Swinging Door Deadbands & SQL Archiving

How to log millions of analog and digital industrial tags without overwhelming hard drives: Boxcar compression, Swinging Door algorithms, deadband tuning, and retention pruning.

  • Logging tags every second without compression produces over 31 million records per tag annually.
  • Analog deadbands log values only when change exceeds a threshold, reducing storage volume by up to 90%.
  • The Swinging Door algorithm preserves peak and valley trajectory slopes while discarding redundant linear points.
