Links, bridges, and jumpers

Previous pageReturn to chapter overviewNext page

The term “link” is used in cadett ELSA for connections between terminals within the same terminal group, which are not made with a conventional wire, but instead with some other physical device. That device is named “link”. Other common names for the same thing are “bridges” and “jumpers”, dependent of what kind of equipment they are found in. In this documentation, the term “link” is used consistently for this phenomenon.

 

In many cases, there is a desire to separate links from wires in the presentation.

 

cadett ELSA automatically calculates which connections should be regarded as wires, and which should be regarded as links. The way that calculation is made, is described here.

 

The starting point is that there are limits to which connections can, or should, be realised with links. These limits can for instance be a maximum length, or other circumstances that can be dependent on the terminal type.

 

cadett ELSA analyses which connections that can be implemented with links. All connections that can be links, are also considered to be links.

 

Since these limits are different depending on the type of terminal, the definitions for these limits are specified in the catalogue. The terminal index refers to the catalogue in which the link definitions can be found. All connections within the same terminal group, and on the same terminal side, are compared with these definitions, at which point it can be decided which are links, and which are not.

 

Links are presented in the terminal list as graphical symbols. A corresponding presentation can also be made when generating terminal lists with the Report Generator.

 

Please refer to the sub-topics listed below for more details about links.
