The detailed specification of a part type takes place within 4. Parts.

General product data
Requirements for operating environment, useful life, reliability, hardware and software, information about applications, etc. The requirements can be documented with the help of text, figures and tables.
General test specification
Information on general test specifications (standard test voltage, standard test temperature, standard test configurations, etc.) with the help of text, figures, tables and parameters.
Behaviour
The behaviour of the system can be described here. For more detailed explanations, see 7. Behaviour.
Architecture

Block / Schematic diagrams
Block diagrams and/or basic circuit diagrams of a part type can be documented here.
Interfaces (<interface>)
For a basic explanation, see 8. Architecture.
An interface can be hydraulic, pneumatic, mechanical, optical or electrical. It can have any number of ports. Mechanical, climatic and electrical characteristics of individual interfaces and ports can be described here.
Signals
For a basic explanation, see 8.2. Signals.
A signal can be hydraulic, pneumatic, mechanical, optical or electrical. In addition, the type (analogue or digital) should also be defined. Characteristics of individual signals (particularly electrical characteristics) can also be described here.
Connection components
In this chapter any kind of connection component can be specified.
Connections
For a basic explanation, see 8.4. Connections.
Each signal described under <signals> can be assigned a port. A connection component can also be assigned for each assigned port.
