Description

Link supervision is currently not defined as an ACSI service, but mentioned in the mapping documents

8-1 defines TCP-Keepalive shall be used for link supervision
8-2 defines XMPP Ping for link supervision
9-2 defines Goose TTL for link supervision

TCP-Keepalive as defined in 8-2 alone might not be sufficient in some scenarios.
It will just proof that the Ethernet Stack of the IED is still alive, but doesn't give any clue on the status of the higher protocol levels or the application itself.
Therefore


Proposal descriptions

TF Communication Supervision (90-28) is defining LTPA logical node to supervise two-party associations covering this issue.
