OpenLNS Programmer's Reference 939
• TRUE. The TypeSpec object is complete.
• FALSE. The TypeSpec object is incomplete. Several
conditions may cause a TypeSpec object to be incomplete.
For example, if you try to get a TypeSpec object for a
network variable with a changeable UNVT type that uses
a configuration property, and the category of the
configuration property is either CAT_INITIAL or
CAT_NULL, then the TypeSpec object would be
incomplete.
Availability

Length
Summary
Indicates the length (in bytes) of network variables that use
the type referenced by this TypeSpec object.
When new values are written to the Scope, ProgramID,
TypeName properties of the TypeSpec object and the
TypeSpec object is passed back to the network variable,
OpenLNS sets the Length property automatically.
When you assign the TypeSpec object to a network variable,
make sure that the value of this property does not exceed the
value assigned to the network variable’s MaxLength
property. Otherwise, the LCA#156
lcaErrTypeLengthTooLong exception will be thrown.
Availability
