The news from the RA technical training sessions last week is that October 2006 is the target release for v16. EDS files are probably up on the website because there are a lot of beta units out there.
Don't be confused by the DeviceNet Tag Generator utility; it's very handy and has the net effect of generating predefined tags, but it's not internally as simple as the CNet and ENet I/O profiles (but covers many more types of devices). I'm using it today with RSNetworx v7.
The big features in V16 are the Add-On Instructions and the new FactoryTalk Alarms & Events instructions.
I plan on having an "AOI Summit" in early November to investigate and promote AOI with my big integrators, so that everybody gets the most from it, especially as regards connecting AOI's to RSView Global Objects.
I'm not going to get too excited about the firmware release until I see it in the wild.
