Echelon NodeBuilder Resource Editor - Manual (Page 35)

The figure above shows the New or Existing Configuration Property Type dialog.
The New Network Variable Type dialog is identical except it does not contain Type
Range Override and Default Value or Inherited from a Network Variable.
2. Enter a name for the new network variable type or configuration property type in NV
Name or CP Name. Network variable type names must start with the letters
“UNVT.” Configuration property type names must start with the letters “UCPT.” By
default the name of the network variable or configuration property type is UNVT<NV
Index>
or UCPT<CP Index>, respectively. The network variable or configuration
property index is shown in the status bar at the bottom of the window. Every new
network variable and configuration property in a resource file set will be assigned a
unique index (i.e. if you create a network variable with an index of 1 and then
remove it, the next network variable you create will still have an index of 2. See
Removing and Obsoleting Resources for more information).
By convention, user network variable type (UNVT) names have an underscore after
“UNVT”; the first letter after the underscore is lower case; and the name uses all
lower case with words separated by underscores (i.e. UNVT_scale_data). By
convention, user configuration property type (UCPT) names do not have an
underscore after the “UCPT” prefix, the first letter after UCPT is lower case, and the
name uses mixed case (i.e. UCPTadcFilter). Network variable type names are
limited to 64 characters, including the “UNVT_” and “UCPT” prefixes. You can use
upper and lower case alphanumeric characters and underscores. You cannot use
spaces or other special characters in names.
