To discuss in WG10:
No
Short Proposal:

The above citations show a need for clarification of the standard. The first citation seems to suggest that a ConnectedAP is only applicable to a server. The second seems to suggest that AccessPoint addresses are required to be unique – preventing a client and server from sharing an IP address.

Standard(s):

IEC 61850-6

Description

A reservation could not be made via SCL for an IED’s report due to the lack of a ConnectedAP associated with the client’s AccessPoint.

The ICD file describes its client and server via independent AccessPoint definitions.

-6 Ed2 :
First paragraph after table 36
“Each connected access point optionally has one server-related address, and additional address
information for real time communication-related control blocks such as GSE control and SMV
control. If all three are missing, it describes only the Subnetwork connection topology, for
example for communication performance studies. For a complete SCD file, either the server
address or at least one control block address shall be specified.”

9.4.3 Address definition
Second paragraph:
“The access point address shall be filled with a unique value at least for server type access
points to get a complete SCD description.”
