Attribute UOM Substitution Parameter
If you have a PI Point attribute with auto tag creation and you want the attribute UOM and PI Point engunits to match, you have to define it twice; once in the attribute UOM field and a second in the attribute configuration string, e.g. engunits=m3. If there was a substitution parameter for the attribute's UOM, you could use it in the attribute configuration string, e.g. engunits=%AttributeUOM%.
Fully agree with all comment below, for those seeking a workaround until development of the functionality :
This function is really needed to improve PI AF...
yes - this is a function we need to have please.
I just ran into this again today using the Integrator for BA where i need to expose the UoM used for attributes...
This is something we need. This is a pain today - we need to do it manually for all output points created from AF.
It should be easier to create PI Points from the AFmodel using the UoM set for the attribute. This will help a lot to simplify that.
When used for template attributes, the engunits could even be set by default to this, ensuring proper alignment
