Data Dictionary
A dashboard item that lists every signal name with its unit, data type, value range and the models that send it, flagging mixed units or types.
The Data Dictionary item lists every signal name across the assets as a data team designs against it: the unit and data type it is stored with, the lowest and highest value in the window, and how many assets and which equipment models send it.
- Flags. A signal stored with more than one unit, or more than one data type, shows them in amber and comes first: the same name means different things on different machines.
- Search. Type part of a signal, unit, data type or model to narrow the list.
- Summary. How many signal names are shown and how many have mixed units or types.
Select a signal to filter the other items of the dashboard by it.

Signal is required: one row per asset and signal. Unit and Data type fill their columns, Lowest value and Highest value the range (bind them with the Min and Max summaries), and Equipment model and Asset the "used by" column.
