Report Control Block Identification and data
▪
Message Name: inserts a name for the GOOSE Control Block. The allowed
characters are 0-9, a-z, A-Z and '_'. Max characters: 32.
▪
Description: inserts a description for the GOOSE Control Block. The not
allowed characters are '<' and '>'. Max characters: 64.
▪
Report ID: Optional RCB identifier. The allowed characters are 0-9, a-z, A-Z and
'_'. Max characters: 74.
▪
Dataset: selects the dataset for this Report Control Block. All the created
datasets will be listed here.
Options
▪
Buffered: internal events (caused by trigger options data-change, quality-
change, and data-update) issue immediate sending of reports or buffer the
events (to some practical limit) for transmission, such that values of data
object are not lost due to transport flow control constraints or loss of
connection.
▪
Buffered Time: specifies the time interval in milliseconds for the buffering of
internal notifications caused by data-change (dchg), quality-change (qchg),
dataupdate (dupd) by the BRCB for inclusion into a single report.
▪
Upon receipt of the first set of internal notification of events of the referenced
data-set, the BRCB starts a timer of the duration buffer time. When the timer
expires, the BRCB combines all internal notifications that have been received
during the time interval into a single report. The next internal notification
following the timer expiration signals the new start of that timer. Range: 1 –
1000 ms. Step 1 ms;
▪
Indexed: When checked the report control block instance names are created
from the RCB name, followed by an index number from 01 up to maximum 15.
▪
Max Instances: To allow multiple clients to receive the same values of data
object, multiple instances of the report control classes shall be made available.
Once a report control block is reserved, by a specific client, no other client
shall have access rights to set the control block attributes. Up to 16 instances
can be configured.
Trigger Options: Specifies the trigger conditions which will be monitored by this
BRCB. The following values are defined:
▪
Data Change(dchg); relates to a change in a value of a DataAttribute
representing the process-related value of the data object
▪
Quality Change(qchg); relates to a change in the quality value of a
DataAttribute.
▪
Data Update (dupd): relates to a freeze event in a value of a DataAttribute
representing a freeze value of the data object (for example, frozen counters)
or to an event triggered by updating the value of a DataAttribute. Data-update
trigger condition may be used to issue sending a report or storing a log entry
into a log when a value of a DataAttribute has updated. Updating may mean
that the value has changed or has been "overwritten" with the same value as
before. The dupd trigger condition can be used as a trigger for statistics values
that may be calculated and updated on a periodic base. Independently of
whether the statistics value has changed or not, the value will be reported or
logged.
