You just need to setup an RSD export in the equipment list. In the properties of the export you can select the devices to include and the IP of the cp3. Once you build the d3 again it will create a RSD that you then import into simpl.?
I have a lighting project created in D3 Pro, but now I need it to communicate with SIMPL project inside the CP3 Processor. This is the first time that I am using a projet in D3 Pro because I have lots of lighting switches and modules I figure that it would be easier using the D3 Pro.
