I think it should be ok. The value of any attribute has no any relateship with the name of the attribute. However, if doing this, it might have some complex setting in your logic. If need some further support, please post your problem with an example in here, and we could discuss on how to achieve your goal.
Yes, this is possible. Have just done this myself in a project where the PI tagname is located in an AFTable, and the Table Lookup DR uses attribute values from related elements in the hierarchy to return the required value from the table. The value of this attribute is then referenced by another that has the PIPoint DR configured.
I have just done it. This is the procedure:
This attribute will show the value of the tag sinusoid, since it is the value of the attribute PIPointSelected.Hope this helps!
- Create a new attribute with no Data Reference called "PIPointSelected" whose value is "Sinusoid".
- Create a new attribute with PI Point Data Reference. After clicking on Settings, select "Tag Name" and write on the text box: "%@PIPointSelected%".
Thank you all. Very useful.
