Merging and bridging of SV streams in a SAM600 system
The configuration of the SAM600 system regarding assignment of streams to
access points is performed with the SV Stream and Port Configuration tool in
PCM600 (see
Section
3
).
On each SAM600 module, one or two ports are reserved for SAM600 system bus
communication depending on the SAM600 module position within the SAM600
system. The other ports can be used as uplink ports.
Each SAM600 module can be configured to send a total of 10 IEC/UCA 61850-9-
2LE streams to its uplink access points. This may be any combination of merged
and bridged streams. The combination of a specific SAM600-CT and a specific
SAM600-VT source stream can be sent to multiple uplink ports in parallel, if each
of the streams has its own unique Sample Value Identifier (svID) assigned.
Each SAM600 module can receive up to 8 bridged streams. These 8 streams can be
freely distributed to all uplink ports in a SAM600 system. Forwarding on the
SAM600 system bus is not affected by this limitation as a SAM600 module is
capable of forwarding any number of IEC/UCA 61850-9-2LE streams between its
SAM600 system bus ports as long as the bandwidth limitation is not exceeded. A
SAM600 module can register up to 8 unique source streams for sending to its
uplink ports. These sources can consist of bridged streams taken in on this
SAM600 module, bridged streams received on the SAM600 system bus, sampled
value stream generated by the SAM600 module itself (SAM600-CT or SAM600-
VT), or sampled value streams received on the SAM600 system bus that were
generated by SAM600 other modules in the system.
summarizes the stream number limits on SAM600 modules. The SV
Stream and Port Configuration tool in PCM600 enforces these limits.
