APPENDIX C
The DataTypeTemplates node defines instantiable logical node types. A logical node type is an instantiable template of the
data of a logical node. A LnodeType is referenced each time that this instantiable type is needed with an IED. A logical
node type template is built from DATA (DO) elements, which again have a DO type, which is derived from the DATA classes
(CDC). DOs consist of attributes (DA) or of elements of already defined DO types (SDO). The attribute (DA) has a func-
tional constraint, and can either have a basic type, be an enumeration, or a structure of a DAType. The DAType is built from
BDA elements, defining the structure elements, which again can be BDA elements of have a base type such as DA.
