Classification of a symbol representation in the sense of below example under Section 5.12.12.5.5.1, “Symbol representation with Phoenix Contact 2903156” can only be created as "Addon", if the part has already been completely classified following the main steps of the electrical classification. In particular this means the creation of classes and attributes as described under Section 5.12.12.3.2, “Connections, IEC function symbols” .
An error free description of function (Section 5.12.12.3.2, “Connections, IEC function symbols”) is precondition (can be omitted for pipeline import and only applies for manual or semi-automatic classifying[55]).
Used classes for symbol representation "advanced" are CNSCAX|GFX|SYMREP [symbol representation(s)], CNSCAX|GFX|1 [symbol connections] and CNSCAX|GFX|2 [text blocks].
The symbols (2D vector graphic files [DXF/DWG/2db]) have to be integrated in PARTproject under Additional export formats (at any place in the catalog).

Note Exactly this ID has to be entered in class CNSCAX|GFX|SYMREP, attribute CNS_DOC_CNSURI. See below.
In the list field, under Type, select the appropriate format.
Enter a description. It will be displayed under Additional export formats.
[55] At this the possibility of a symbol library is offered so that the following steps have only to be done once when creating the library. Then equipping a part with symbols only means applying a template basically, which already contains the described symbol classification.
