IEC61850.Tissue #1754 Event driven schedules - Type of InSyn missing
Include in edition 3 - not very urgent
Part 7-4, page 169, clause 6.6.9, table 70:
The type of the external trigger InSyn in Table 70 is not defined.
Note: InSyn is also used for Statistical LN … but the definition there is not applicable for scheduling.
“F.3.2.3 External synchronization” defines BOOLEAN … and the behavior only for statistical LN … NOT for FSCH!
Define the Type of external trigger.
Replace the current text:
“Object reference of the external trigger if the
schedule is triggered by an event.”
“Object reference of the external trigger to start the schedule
if the schedule is triggered by an event.
The Type of the external trigger Data Attribute
shall be BOOLEAN.”
Note: This Data Attribute may be located in the same IED (local issue how the event is communicated) or in another IED (needs GOOSE or Report to communicate the event from one IED to another IED).
Alternatively a new clause like F.3.2.3 External synchronization could be added in K.2.4
