Figure 1637: The Multi-terminal macro is used to insert multi-terminals.
Multi-terminals are not cadett ELSA symbols in the way that ordinary main symbols are. Instead, they work in a similar way as the standard terminals of cadett ELSA. In other words, they really consist of two symbols, where one is always the same, namely a logical symbol containing the attributes. That part is predefined in the symbol database, as a terminal symbol. The other symbol only contains graphics and is defined by the user. These two symbols are placed on top of each other. This is however not enough to create a complete multi-terminal, since the sizes, positions, rotations, and text justifications of the attributes are also user-defined. Therefore, a complete footprint of the multi-terminal is also part of a multi-terminal definition. That footprint contains the appearances of all attributes. A complete multi-terminal definition is stored under a name chosen by the user. You may have any number of such definitions.
Each multi-terminal definition determines:
1.The name of a user-defined block that contains the graphics
2.A complete footprint of all attributes including position, rotation, text height, and text justification for each one of them.
The multi-terminal definitions are global, meaning that they are stored in the symbol library accessible for all projects and for all users.
As an additional feature, it is also possible to define project related "aliases". An Alias is an alternative project specific name for a multi-terminal definition. You can for example use a terminal group name as alias, so that different terminal groups may have different graphical appearances.
