WSCAD 5 draws the cables in circuit diagrams by means of a cable wire symbol. Cable-wire type symbols are positioned on the connection lines. While the cable line formerly represented a special element, which is still supported for reasons of compatibility with previous versions, the cable-wire type symbols are flexible in application and numbering.
When drawing the line, the cable-wire symbols are placed on the intersections automatically. Each cable-wire type symbol therefore corresponds to a wire in the cable and can be numbered automatically from top to bottom or from left to right.
The symbols themselves consist of a body (e.g. a short, diagonal line) and a pin. In addition, the cable designation and the cable type are converted into reference names and symbol names of the cable wire symbols. Using a symbol for a cable also has the advantage that it is possible to work with the database, so that values from the database can be processed in the task lists (e.g. material lists).
Cable-wire type symbols can be numbered manually and automatically, in the same way as terminal connections. The type of numbering is determined in the configuration.
Instructions on creating cable lists and cable diagrams
Cable designations are only transferred when the cable type and the cable designation are both present or can be assigned by the external destination. (When the cable designation for the external destination is missing but the cable type is present, the reference name of the external destination with the prefix W is used as the cable designation.)
When creating cable lists/cable diagrams, the automatic system must know which components are internal and which components are external. In the case of a terminal/symbol connection, the assignment is given by the terminal connection: if the symbol (e.g. motor) is connected to the external connection of the terminal then the symbol is external and the terminal strip is internal. With a terminal/terminal connection, the assignment is somewhat more difficult. Every symbol which is not a terminal is recognised as an external destination but is connected to a terminal. Or this symbol is explicitly labelled using !ext.
When connecting external terminals / externally or internal terminal / internally or connecting between two symbols, it is not possible to assign automatically without additional information. This information must be entered in the form of the word !ext (also possible without the ! character) in the Text1 or Text2 lines of the symbol parameters of the external symbol. With several symbols (e.g. terminals), this information must be entered for each symbol.
Hint
The information !ext is necessary for symbol/symbol or terminal/terminal connections
