PI Tuning Toolsclick-to-download

As a PI Administrator, you probably have thousands of tags in your PI System. Each tag has compression settings that determine which of the collected values will be stored to the PI Archive. Typically, you have some rules for assigning compression settings based on the type of data. For example, you may set all temperature tags with a compression deviation of .1 engineering units.

The problem with this type of compression assignment is that different tags have different behavior. With the same compressions settings, some tags may store a value per second while others store a value per hour. When you look at the tag data in the PI Archive, you are looking at the data after compression. How do you know if the data storage if accurately representing the behavior of the tag data? How can you compare pre-compressed tag data with compressed tag data to see what compression is doing to your data?

EXELE PI Tuning Tools allows PI system administrators to easily identify “noisy” tags and to tune those tags and the PI archive through intelligent changes to tag compression settings (compression deviation).

PI Tuning tools consists of 3 applications


Archive Analysis

Identify noisy or empty PI Tags


Compression Analysis Data Collector


Collect raw data for PI tags
