Clause: Figure 6

Paragraph: 6.1

Category: Issue for edition 2 of this part

Issue

In figure 6 it is shown that one access point can have zero or more servers. In addition one IED can have 0 or 1 server. That means that one access point must cover several IEDs and I do not believe that this is the idea.
So something must be wrong.

In figure 19 an IED can have one or several access points and each access point can have 0 or 1 server or 0 or 1 serverAt.

There is no direct relation between IED and server and therefore it is hard to define if there is a limitation on servers in the IED.

Proposal

Agree if one IED can have more than one server and update the document accordingly in the next version.
