PRS-7910 35
PRS-7000 series relays, besides the logical nodes we describe above, there are some other
logical nodes below in the IEDs:
9.4.5 Server Features and Configuration
9.4.5.1 Buffered/unbuffered Reporting
IEC61850 buffered and unbuffered reporting control blocks locate in LLN0, they can be configured
to transmit information of protection trip information (in the Protection logical nodes), binary status
values (in GGIO) and analog measured/calculated values (in MMXU, MMTR and MSQI). The
reporting control blocks can be configured in CID files, and then be sent to the IED via an
IEC61850 client. The following items can be configured.
TrgOps: Trigger options.
The following bits are supported by the PRS-7000 series relays:
－ Bit 1: Data-change
－ Bit 4: Integrity
－ Bit 5: General interrogation
OptFlds: Option Fields.
The following bits are supported by the PRS-7000 series relays:
－ 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
IntgPd: Integrity period.
9.4.5.2 File Transfer
MMS file services are supported to allow transfer of oscillography, event record or other files from
a PRS-7000 series relay.
9.4.5.3 Timestamps
The Universal Time Coordinated(UTC for short) timestamp associated with all IEC61850 data
items represents the latest change time of either the value or quality flags of the data item.
