Echelon LNS DDE Server - Manual (Page 116)

2. US = United States measurement system format. These formats will be
automatically selected if the operating system is configured to use United
States units.
3. LO = operating system (e.g. Microsoft Windows) locale-specific format. This
will cause the data type to be displayed as configured in the operating
system. For example, the operating system could display the date in
MM/DD/YYYY format or DD.MM.YYYY format.
The SI and US classes have a special relationship: Any type that has at least one
format defined with one of these classes must also have at least one format
defined with the other one of these classes. Any format definition that specifies
one of these classes cannot specify the other one—they are complimentary.
Membership in these classes, together with the Windows system default locale,
determines the runtime default format as described under Default Format.
Any format definition that contains the list-separator, date, or time locale-
specific specifier must be a member of the LO alternate format class. This aids
in ensuring backward compatibility and also make it obvious to the user that
locale-specific data transformations will occur when using this format.

website for more information.
Language File
The language file defines all language-dependent strings. The language the file
supports determines the extension of the language file. Two language string files
are included with the LNS DDE Server, STANDARD.ENU for English (US), and
STANDARD.ENG for English (UK). Each string reference from the type file is via
an index key into the language file. Each language file uses the same index for a
particular string, thus it is simple to switch from one supported language to
another. Additional language files will be placed on the L ON M ARK web site as
they are available.
Functional Profile Template File
The functional profile template file defines functional profile templates. A
functional profile template is a specification of a framework for a LONMARK
object. The functional profile template specifies the required and optional
network variable and configuration property components of a LONMARK object.
The actual implementation of a LONMARK object in a device may not contain
some of the optional components. It may also contain additional network
variable or configuration property components, these latter being referred to as
manufacturer specific. Device manufacturers should provide functional profile
template files for their user-defined functional profiles, and for their standard
functional profiles that use any manufacturer-specific network variables or
configuration property types.
The functional profile template file also defines default values, descriptive
strings, and validation information for the network variable and configuration
property components.
