                  Communication testing must always be carried out by a KNX accredited test lab.
                  For most of the tests to be carried out, a common software test platform named EITT
                  (KNX Interworking Test Tool) is used. In other words, all products are not tested against
                  one another but against a common test reference, which simulates a sensor sending
                  frames (when testing an actuator functionality) and an actuator receiving frames (when
                  testing a sensor functionality).
                  The extent of the communication testing depends on whether the submitted product
                                                            7
                  contains a certified system software (stack)  or not.






















                  7  The system software is often referred to as a stack.
