Not that, the lmnl files in 3.0 and up are not right. Staefa says that it is a Tridium problem, its not, Staefa did not keep up with the Lon world so there is a real problem with this line. If you commission a new Four Loop on AX 3.0 and up it will most likely eat the app. Making the controller no good. The best way for the Four Loop is to commission in R2 first. Once it has been commissioned the problem goes away. The rest of the line (Except for VAV104s) is another can of worms and requires a real understanding of Tridium/Lon. All of this can be worked around.
