Multiple Functional Blocks with Multiple UFPTs
The following example demonstrates how to use multiple functional block arrays in a model file to
create multiple sets of functional blocks that are instances of their respective UFPTs. You could then
write separate FPM applications for the UFPTs instantiated by the model file. When you deploy the
FPM applications on the SmartServer and select the XIF generated from this model file, the internal
FPM device will include arrays of the functional blocks that are separate instances of their respective
FPM applications.
