1694   Associate service refusal based upon ServiceSupportedCalling

Created: 19 May 2020

Status: Not Applicable

Part: Part 8-1 (2020; Edition 2.1)

Clause: 10.2.2.1

Paragraph: 1

Issue

Interoperability issue can arise if IED refuses ACSI associate based upon MMS-Services-Supported. For example, if a server supports buffered reports but client does not claim support for MMS “informationReport” then interoperability is still possible if the client never enables a report in the server. A similar issue exists with server supporting obtainFile but client not supporting fileOpen.

Proposal

Add text to clause 10.2.2.1 (Associate) “an IED shall never refuse an Associate request based upon MMS-Services-Supported.”

Discussion Created Status

Proposal Refused.
