Unbuffered Report Control Block
URCB data is sent immediately to the connected IEC 61850 Client. If the
transport data flow is not fast enough to support the movement of this data, some
may be lost. The IED can have multiple instances of the URCB data, and in this
case, the IED server manages the separation of the instances transmitted to the
IEC 61850 Clients.
If a URCB is mapped in the gateway’s configuration, then the IEC 61850 driver
automatically turns
on the Report Enable (RptEna) for the IED’s URCB.
The unbuffered reports is sent automatically from the IED to the gateway while
Report Enable is on.
The IEC 61850 driver and configuration software implements URBCs the same
as BRCBs.
Unsupported Report Control Block Features
OptFlds are the optional fields that the IED can include in the report:
 Sequence number
 Report time stamp
 Reason for inclusion
 Data set name
 Data reference
 Buffer overflow
 entryID
The gateway only updates the value of the tags (Data Attributes) in the tag
database. The optional fields from the reports are not stored in the tag database,
and unsupported.
