I want to ensure that my intended use of the Profinet Community Stack is allowed under the Community Stack License. I understand it as allowing my company (a PI member company) to use and adapt the code within the Community Stack to create a Profinet adaptation layer for our hardware, then use that adaptation layer in our final product. I also understand this to be royalty-free. I am using the example from the community stack's 1.0 release, whose files are licensed under the community stack license, as a base for the adaption for our embedded Linux system.
Our intent is to use the community stack to implement Profinet on our industrial device product, then certify that product through a Profinet Test Center, and then sell that product to our customers. As I understand the license, this entire process should be royalty free with no associated fees for the use of the Profinet Community Stack.
Note that our product is a Profinet Device, not a Profinet Controller.
Is my understanding correct?
