PI AF - Port tab in element's

Are you asking because you need to use it or because you see it in PI System Explorer and you want to know what it does? Ports, models, and transfers are all used only by Sigmafine, so if you are not using Sigmafine, then don't worry about the "Ports" tab. See this question for more details.

Also, next time, consider posting a question as a question rather than as a blog post.
