3. CAx-Basis Aspect

In this CAx-aspect, basic CAx-planning-relevant information shall be given to the article which are independent of connections and functions. The cardinality properties "Number..." can be used to describe possible article-specific variants. Please refer to the following figure for the subject areas concerned.

Figure 14: CAx-Basis-Topics

The code letters support a uniform reference marking system for the unambiguous identification of the objects in the plant system during planning, design, implementation, operation, maintenance and disassembly. These code letters describe functions. In addition to the main function, the identification letters can also be used to describe help functions of an article. These functional descriptions of the articles are used by computer-aided modelling tools and are also part of the following functional descriptions.

letter code of classes according to purpose or task (IEC 81346-2)

Letter classifies the main function according to IEC 81346-2 Chapter 5.1 Table 1 of 2009 (IEC) / 2010 (DIN). The property indicates the purpose for the entire product. The individual functions within the product itself can also be differentiated with more specified code letters under the function identification. Further see: 4.2 Function

Is required by the CAx-systems to generate the resource identification label.

letter code of subclasses according to purpose or task (IEC 81346-2)

Letter classifies the sub-function according to IEC 81346-2 Chapter 5.2 Table 2 of 2009 (IEC) / 2010 (DIN). The property indicates the purpose for the entire product. The individual functions within the product itself can also be differentiated with more specified code letters under the function identification. Further see: 4.2 Function

Is required by the CAx-systems for generating the resource identification label and for function-oriented plant modelling.
