Communication Protocol
318 PRS-7367
A data set is an ObjectReference set of orderly DATA or DataAttrubutes. It usually includes the
following attributes:
ldInst: the logic device containing the DATA or DataAttrubutes;
lnClass: the logic node class containing the DATA or DataAttrubutes;
lnInst: the logic node instant number containing the DATA or DataAttrubutes;
Fc: all attributes of functional constraint required by DATA or DataAttrubutes;
doName: name of DATA, or name belonging to the DataAttrubutes;
daName: attribute name.
9.4.3.2 Report control block
IEC 61850 has defined the report control block, to describe how the changed information is
actively submitted via report service when the data set members have changed. Report control
blocks are classified into buffered report control block and non-buffered report control block. In
case of communication interruption, the newly occurring event will still be stored as buffered report
control block, otherwise, it is a non-buffered report control block.
The report control block performs the control of report submission via a series of attribute
configurations. Specifically, it has the following important attributes:
RptID
The identity of report control block, globally unique within the scope of LD. If the RptID of the RCB
is set by the client side as NULL, RptID is full path in the report submitted by device.
OptFlds
The option fields OptFlds contained in the report. The PRS-7000 series device supports the
following option fields:
－ Bit 1: Sequence-number
－ Bit 2: Report-time-stamp
－ Bit 3: Reason-for-inclusion
－ Bit 4: Data-set-name
－ Bit 5: Data-reference
－ Bit 7: EntryID (for buffered reports only)
－ Bit 8: Conf-revision
－ Bit 9: Segmentation
When an item is set as 1, the corresponding information will be embodied in the report.
DatSet
The name of the data set associated with the report control block and under the same LD. The
members of this data set are monitored by this report control block.
