I get the following message:

 ************* Testing Individual Branch Integrity                  
 ** Severe  ** Non-unique node name found, name=NODE 3              
 **   ~~~   ** ..1st occurrence in Branch=RH Supply BRANCH      
 **   ~~~   ** ..duplicate occurrence in Branch=RH Demand FEED BRANCH      
 ** Severe  ** Non-unique node name found, name=NODE 20             
 **   ~~~   ** ..1st occurrence in Branch=RH Supply  BRANCH      
 **   ~~~   ** ..duplicate occurrence in Branch=RH Demand RETURN BRANCH

but when I make unique node names for supply outlet node -demand inlet node and vice-versa, i get the error messages that Plantloop Demand inlet and Supply outlet nodes must be the same.

What am I doing wrong?

Without having your IDF file or a schematic of your plant loop, hard to tell. I suggest you read carefully the Plant Application Guide (also as a PDF in your E+ install folder) and review the rules that govern loop topology in E+

I solved this. One must change the shared node names in three places: PlantLoop, Branch, and Component (E.G. pipe) - while I was only doing it in 2 of the three....

Glad you solved it. You can move your comment as an answer and accept that.
