defined by the functional profile – these are called implementation-specific
network variables and configuration properties.
For example, Figure 10 illustrates standard functional profile number 3050, the
Constant Light Controller profile. This profile defines two mandatory inputs, one
mandatory output, and one optional input. It also defines one mandatory
configuration property and eight optional configuration properties.

Functional profiles are defined in resource files . You can use standard functional
profiles defined in the standard resource file set, or you can define your own
functional profiles in your own resource file sets. A functional profile defined in a
resource file is also called a functional profile template .
Standard functional profiles (also called standard functional profile templates, or
SFPTs) are defined by L ON M ARK International. You can view all currently
defined standard functional profiles online at types.lonmark.org . Additional
documentation for the standard functional profiles is available under Technical
Resources at www.lonmark.org . You can create your own user-defined functional
profiles (also called user functional profile templates, or UFPTs) using the
NodeBuilder Resource Editor. You declare functional blocks in your Neuron C
applications using fblock declarations. These declarations are described in this
chapter.
You can declare up to 254 functional blocks in a Neuron C application or model
file, resources permitting.
A functional block declaration does not cause the compiler to generate executable
code, but the compiler generates self-identification and self-documentation data
