Creating and Modifying Resources

applies to a network variable, Applies To also
specifies the specific network variable.

If the configuration property applies to the entire
functional block but itself implements an
inheriting type, the property will derive its type
from the principal network variable. A principal
network variable must be defined in this case.

String Information

A language-specific name for the configuration
property within the profile and a comment that
describes the purpose of the configuration
property within this profile. See Creating and
Modifying a Language String
for more
information on creating and linking to language
strings.

Type Range Override
and Default Value

Minimum, maximum, invalid, and default values
for the configuration property member. A
configuration property member can have a
minimum and maximum range restriction that is
more restrictive than the range restriction for the
configuration property type it is based upon, and
can have different default and invalid values than
the base type.

You can enter raw data into this field using any of
the following methods:

A continuous stream of hexadecimal digits.
Example: 01010101ABCDABCD00

Dash, colon, or dot separators for optional
grouping. Example: 01010101-ABCDABCD-
00

A single asterisk character followed by a
decimal multiplier, which repeats the
preceding sequence of hexadecimal digits.
Example: 01*4-ABCD*2-00. The raw data
display may not match what you originally
entered. For example, if you enter “00-00*4,”
it will later be shown as “00*5.”

Using Cascading Resource File Sets

When adding network variable or configuration property members to a functional profile,
you can add resources that are defined at the profile’s scope, at the standard scope (i.e.
scope selector 0), or at any matching scope that is numerically less than the profile’s
scope.

For example, your company may maintain several resource file sets at different scopes: a
corporation wide set with general-purpose definitions at manufacturer scope (scope
selector 3), and a second set with more specific resources at device class scope (scope
selector 4). If the scope 4 resource file references any resources in the scope 3 resource
file, the two resource file sets are known as cascading resource file sets.
