Overview of the terminal assignment

This overview indicates which system parts can be connected for all
terminals in the module. Depending on the system, one of the
components can be connected to the terminal (e.g. "VR2" or "PR2" to the
terminal "VR2"). Depending on what the module is used for,
simultaneous connection of a number of components may be required,
or may need to be excluded.
