For full system visualisation, telegrams shall be allowed to pass the Line Coupler. To this end, a dummy device is inserted in the ETS project. It contains all the Group Addresses required by the visualisation system. The ETS takes the group addresses from the dummy device into account when creating the filter tables. Fill VisualizationDummy helps you to link a dummy device in the ETS with a list of Group Addresses for a visualization. Product data for dummy devices can be obtained from several manufacturers. The information about the Group Addresses can be read either from a file (different formats are supported), or the Group Addresses can be selected from the current ETS4 project by drag and drop. The ETS apps can be purchased via the KNX Online shop.
