Using Correlia
You can discover the correlations between your assets by opening an asset dashboard and clicking on the 'Correlations' button.
This will open the Asset Correlation Page.
The Correlation Page
This page has a heading for every property your asset has. Underneath that is a list of all of the correlations the system has detected with other properties across your system.
These may be internal properties (properties on the same asset, such as a machine having an 'actual' and a 'target' temperature that are strongly related), or they may be external properties, found on other assets in your system.
Correlation Strength
Each correlation has a given strength, expressed as description and a percentage.
Correlation Quality | Percentage |
---|---|
Direct | 100% |
Strong | >90% |
Indirect | >75% |
Direct correlations are often control signals or other signals that move perfectly in-sync with one-another. Often, the target values sent from a control system will be directly correlated.
Strong correlations can often indicate a cause-and-effect relationship between properties. For instance, a target speed often has a strong correlation with the actual speed, the requested position of a machine with the current position etc.
These correlations aren't 100% due to lag in the signal or response, but are otherwise moving at the same times.
Indirect correlations are quite weak - many of these won't be genuine and instead will be simply coincidental. However, this is also where you might discover unexpected links and relationships that show complex interactions.
