There's no functionality on the PLC side to support this. It's easy to build this from C# by reading data in a polling fashion, however to create a solution that fits everybody is an entirely different story. That by itself is reason enough not to implement this in S7NetPlus.

I wouldn't mind providing some guidance on this problem though, or a sample implementation that might fit your needs. Let me know if you need any help.

Hi! I think an example about this "subscription" would be a wonderful example, for example I will use the ReactiveX library, what would you use?
