<ul></ul><p>8-1 only maps what is defined in the ACSI.<br />The signature of the 7-2 SetDataValues is 1 (one) Reference. The mapping of SetDataValues therefore maps 1 (one) reference to 1 (one) MMS VariableAccessSpecification.</p>
<p>The "s" of values in ACSI SetDataValues is NOT determine by the usage of multiple References, but by the usage of multiple values that are needed to set a single FCD. "Values for all data attributes of A data object referenced by FCDA".</p>
<p>In other words: IEC 61850-7-2 also restricts the service SetDataValues to a SINGLE IEC 61850 reference.</p> IEC 61850 User Feedback Task Force - Improvement #3098: Need to Change 8-1 to allow multiple DOs to be writtenhttps://redmine.ucaiug.org/issues/3098?journal_id=32422021-08-09T12:02:27ZHerbert Falk
<ul></ul><p>Then we should evaluate changing 7-2 and 8-1. MMS supports the writes of multiple Variable Access Specifications and it is the same as writing a DataSet.</p> IEC 61850 User Feedback Task Force - Improvement #3098: Need to Change 8-1 to allow multiple DOs to be writtenhttps://redmine.ucaiug.org/issues/3098?journal_id=32432021-08-09T12:08:48ZThierry Dufaurethierry.dufaure@siemens.com
<ul></ul><p>Remember that ACSI has an object-oriented approach. The SetDataValues service is associated to the GenDataObjectClass and not to the GenServer.</p> IEC 61850 User Feedback Task Force - Improvement #3098: Need to Change 8-1 to allow multiple DOs to be writtenhttps://redmine.ucaiug.org/issues/3098?journal_id=32572021-08-17T12:43:11ZTom Berry
<ul></ul><p>Background:<br />The requirement is to update multiple values in a schedule consistently.<br />Often only a subset of the schedule values may need to be updated, for example ValASG14 to ValASG48<br />Ideally the update should be done via a single message, with a single result.</p>
<p>Part 7.2 services appear to support two alternative methods but neither seems efficient.<br />- A single message with all the values whether they have changed or not<br />- One message per changed value</p> IEC 61850 User Feedback Task Force - Improvement #3098: Need to Change 8-1 to allow multiple DOs to be writtenhttps://redmine.ucaiug.org/issues/3098?journal_id=33842021-09-29T09:05:03ZCarlos Rodriguez del Castillo

<ul><li><strong>Discuss in Upcoming Meeting</strong> changed from <i>No</i> to <i>Yes</i></li></ul><p>The underlying MMS protocol supports it, but we do not have the ACSI service.<br />Do we want to change the standard?<br />What is the use case from WG17?<br />Action item for Carlos: Ask Frances Cleveland about the use case and then we can study it.</p> IEC 61850 User Feedback Task Force - Improvement #3098: Need to Change 8-1 to allow multiple DOs to be writtenhttps://redmine.ucaiug.org/issues/3098?journal_id=35032021-11-23T15:23:55ZTom Berry
<ul></ul><p>The original use case (from Japan) is short term planning within a day<br />A schedule is prepared a day ahead. The schedule execution starts as normal.<br />During the day something happens which means part of the schedule for the afternoon or evening needs to be changed.<br />As comment #5 - option 1: the entire schedule (maybe 96 values) must be re-written, or a series of messages sent to update individual values one by one.</p>
<p>An alternative modelling approach: the IED needs to support both the periodic schedule and one or more alternative, short schedules with a higher priority.<br />When needed the alternative schedule(s) are updated and enabled to temporarily override the base schedule.</p> IEC 61850 User Feedback Task Force - Improvement #3098: Need to Change 8-1 to allow multiple DOs to be writtenhttps://redmine.ucaiug.org/issues/3098?journal_id=38222022-03-29T14:20:05ZVladan Cvejic
