By simply writing a VI that does not sub-divide its functionality into two parts, you are able to download a non-time critical program to the FieldPoint RT module. The division of the loops is a function of how you implement the code and not directly a function of the LabVIEW RealTime engine.
In my experience, a significant number of programs that are downloaded into Real-Time targets are frequently not-divided into time critical vs non-time critical components. Sometimes that is deliberate (becuase it makes no difference) and sometimes it is due to inexperience on the part of the programmer. Either way, there is nothing preventing you from downloading code that does not have different priority loops.
