 * ToDo: - Assign Adsress of digital input for homing switch "iHomeDigIn" via parameters (in evalReceived Message, Line 116).
 *       - Homing Event should be defined by a parameterfile and handed to CanDrive... e.g. via the DriveParam.h (in inithoming, Line 531).
 *               - Check whether "requestStatus" can/should be done in the class implementing the component
