Increasing the dynamic range of compressed data

I see too often customers struggling to find the right exception and compression settings. When exception/compression are not well defined, they end up having too many values or missing values, what causes a lot of problems when the affected tag i...

Link tuning parameters to the UOM database

Many of the tuning parameters have units, but the unit can only be found in the tuning parameter's description and is not written consistently (sometimes written in full, sometimes abbreviated, sometimes written as a symbol). Linking the tuning pa...

Being able to activate the Log of abnormally long request made to the PI Data Archive

It would be helpful to determine which users or applications made heavy requests to the Data Archive Server. This could be an option to be activated or not. Logging the ip, user identity, concerned tags, duration of the request Those information a...

Preserve variable-attribute mapping upon attribute path change

Currently, if a variable is mapped to an attribute and the attribute's AF path changes, the variable must be remapped to the attribute. Instead of relying on the attribute's full path to identify the attribute, each attribute should be identified...

Introduce jump labels in analysis expressions or attribute config strings

The traceability of cross-element analysis in the PI System Explorer would be greatly improved by using jump labels on relative or absolute paths in the expression or in the ConfigStrings. For example, you could jump to the referenced element or a...
