# Add Input Signal from Higher Level

This action adds a new input signal coming from a higher-level (or top-level) subsystem to the current subsystem you are working on. This helps you to focus your work on the current subsystem and connect the new high-level inport to an external signal later. Often these high-level connections are established by additional tools, which automatically generate the highest levels of the model.

MoRe remembers the level of the last source system and selects the subsystem on this level as the source the next time you select the action. This makes things quicker if the signals should always come from the same level.

The name of the ports and lines to be created is taken from the clipboard when the dialog is started. This speeds up the action if the name was copied elsewhere before.

Example:

Usage:

Change to the target subsystem in which the signal is to be used. Start the action from the MoRe menu. In the opened dialog select one of the parent subsystems as the source system of the signal. Enter a name in Name of Created Ports and Lines. You can select whether the start line or all lines should also be named. This is optional. Start the action with the Ok button.
