The relevant internal jumpers, saddle jumpers or wire jumpers are generated from all of the connections that run between distributed terminals on a terminal strip when updating the connections. Internal jumpers are generated between associated distributed terminals (same function definition, same DT, same terminal designation, same level number); saddle or wire jumpers are generated between distributed terminals that are not associated.
Automatically generated internal jumpers
If the Connect associated distributed terminals automatically project setting is activated, distributed terminals from a terminal function are connected automatically even if no drawn connections exist between these. Internal jumpers are generated when updating the connections between associated distributed terminals. These automatically generated internal jumpers are each created on the last connection point of the terminal function. The order of the distributed terminals in the terminal strip navigator is key to generating the internal jumpers.
All distributed terminals with the same DT, same, occupied terminal designation and different connection point designation are viewed logically as one terminal whose connection points are connected to each other.
Jumper optimization
The graphically drawn connections between the distributed terminals do not always match the logically required connections for jumper creation. For example, distributed terminals can be graphically connected with each other repeatedly. If the Jumper optimization project setting is activated - no matter the connections drawn - possible saddle jumpers are generated between the terminals rather than wire jumpers. The internal jumpers are also re-generated. The graphical connections only show which distributed terminals are always connected to each other but not between which individual terminals the jumpers exist.
The saddle jumpers created when optimizing the jumpers are each placed on the first distributed terminal (with the smallest connection point designation) from the last to the next to last connection point of the terminal. The connection point type that is set in each case for the last terminal connection point determines what type of jumper / connection is created. Normally the last connection point should have the "saddle jumper" connection point type.
