In nE2DeviceExt, it is possible to link nano EDGE ENGINE components by dragging a wire from one component to another.
Warning!
Linking in nE2DeviceExt works only between nano EDGE ENGINE components. Do not link Niagara components from other modules/drivers with nano EDGE ENGINE components.
Reference Linking
Reference link is designed specifically to connect Data Point class components (in the Applications container) with network point class components (in the Networks container). A reference link transfers values along with the component's status.
To learn more about the reference linking, please refer to the nano EDGE ENGINE Programming user manual.
As network points are situated in the Networks container and Data Points are situated in the Applications container, Reference links are created using the Link Mark and Link From options from the context menu.
To create a reference link, right-click a network point and select the Link Mark option.
Once the link is marked, right-click on the desired Data Point and click the Link From option.
In the dialog window that pops up, select “reference” slots on both Source and Target points.
Once the reference is created, a new 'Nano Reference' slot appears in the component.
