NCC# Description
483 The fblock’s FPT attempts to inherit from a standard FPT, but no standard FPT
was found with a matching key [NCC#483]
A user-level FPT may indicate (in the L ON M ARK Device Resource File that
contains it) that it inherits members and properties from a standard FPT.
The inheritance is by key , a 16-bit value associated with each FPT.
Standard FPTs have key values from 0-19999, and user FPTs that inherit
from standard FPTs must have matching keys. User FPTs that do not
inherit should have keys 20000 and above. This message either indicates a
problem with the key used for FPT inheritance, or it indicates that the
standard FPT is missing. Perhaps the standard file is out of date. The
latest standard L ON M ARK Device Resource Files can be downloaded from
the www.lonmark.org website.
484 The FPT used in the fblock inherits from an obsolete FPT [NCC#484]
The L ON M ARK Device Resource Files permit FPT, NVT, and CPT
definitions to be marked as obsolete. This means that a replacement FPT,
NVT, or CPT is available, and the use of the obsolete item is discouraged
(though it is permitted). In this case, the user FPT is inheriting from a
standard FPT that has been marked as obsolete by L ON M ARK
International. Contact L ON M ARK International for more information about
the obsolete FPT, NVT, or CPT.
485 Cannot inherit type for property from principal NV because principal NV of FPT
is unimplemented [NCC#485]
A configuration property that uses type inheritance from a network
variable can also inherit from a functional block. In this latter case, the
FPT must designate one of its network variables as the principal network
variable. The principal network variable designation is solely for the
purposes of type inheritance. In the case of FPT inheritance, if the user
FPT overrides the standard FPT's principal network variable, but does not
designate one of its own, this leaves the principal NV as unimplemented.
Then, a configuration property for that functional block, using type
inheritance, has nothing to inherit from.
486 The fblock uses an FPT that has advanced features and requires LNS versions
3.2 or later [NCC#486]
FPT inheritance and FPT records whose member numbers do not match
the member indices are not fully supported in LNS prior to LNS version
3.2. This might result in parts of the devices not being fully or correctly
recognized when deploying this device in a network managed with an
earlier version of LNS.
