In the Numbering series for wires section, you can specify three separate numbering series that can be used for wire numbering, primarily automatic wire numbering.

 

Which numbering series that should be used for which connection type is specified in the Wire numbering section, where a description of "connection types" as such us also provided .

 

Each numbering series is specified with a Start value and a Step value.

 

The Start value consists of two logical parts, where the first character of it is considered to be a prefix. The remaining part of the Start value, is interpreted as the true start value. It must therefore be an integer.

 

The Step value is also always a numerical value, an integer.

 

This means that, for instance, a Start value of 01 will result in all wire numbers belonging to the series beginning with a zero. The zero is a prefix. The start value will be 1. This results in a numbering series that begins with 01 and continues with 02, 03, and so forth. After 09 come 010, 011, and so forth.

 

A Start value of 500 will be interpreted as a prefix of 5, which all wire numbers in the series should begin with. The start value, where the prefix is excluded, is then 00. This is followed by 01, 02, and so forth. After 09 come 10, 11, 12, and so forth. After 97, 98, and 99 comes 100.

 

The result of all this, is the following wire numbers:

 

500, 501, 502 ... 509, 510, 511 ... 598, 599, 5100, 5101, 5102 ...

 

As described above, the start value and the prefix are defined in one single project parameter. The first character in the entered value is interpreted as a prefix. The prefix can be any character, like a digit or a letter. The thereafter following characters are interpreted as a start value and must be an integer.

 

Space (" ") used a prefix is interpreted as no prefix at all. To achieve a wire numbering of 1, 2, 3, 4 and so on, you therefore specify " 1" as Start value, with space as first character.

 

 

The start value is incremented with the Step value for each new wire. The step value is always a positive integer.

 

Technical information

The numbering series are reinitialised (restarted) for each numbering area, as numbering areas are defined by the Restart of wire numbering (numbering range) project parameter.

 

When a numbering series is reinitialised for a new numbering area, a determination is made whether any fixed wire numbers already exist for wires that belong to that numbering series. If that is the case, the numbering will start from the highest existing fixed wire number, provided that it is larger than the specified start value. In that way, all risk of “conflicts” between existing and new wire numbers is avoided.
