Operation Manual
Each SAM600 module with analog inputs (SAM600-VT and SAM600-CT) is a
self-contained SAMU and can be used in different IEC 61850 process bus
architectures. On SAM600-CT and SAM600-VT modules two independent IEC
61850 access points are available in order to publish analog measurements
according to IEC/UCA 61850-9-2LE. On SAM600-TS modules up to five
independent access points can be configured, and also in redundant configuration.
A SAM600 system can synchronize to external clocks by means of IEEE 1588
Precision Time Synchronization Protocol (see Section 2.1.4), or by the use of a
SAM600-TS modules, to 1PPS..
A SAM600 system can be built by chaining up to 10 SAM600 modules through a
SAM600 system bus. Alternatively, the modules can be connected as a HSR ring
for added communication reliability. A SAM600 system bus ring can use optical
and electrical ports on the SAM600 modules. The connected SAM600 modules act
as a single SAMU with scalable and configurable IEC 61850 access points.
A SAM600-TS module is optional in a SAM600 system. A
SAM600 system can contain a combined total of seven SAM600-
CT and SAM600-VT modules. Up to three SAM600-TS modules
can be added to a SAM600 system.
Merging and bridging of IEC/UCA 61850-9-2LE streams
With a SAM600 system, IEC/UCA 61850-9-2LE based streams that consists of
information provided by individual SAM600 modules can be configured and
published on all IEC 61850 access points of the SAM600 system. This allows to
adapt to various communication architectures and performance requirements of
client devices such as IEDs.
Sampled value streams from external sources (e.g. optical sensors) can be
“brdiged” through a SAM600 system to several IEC 61850 access points. External
streams cannot be merged with SAM600 internal streams.
Each SAM600 module provides its measurements as IEC/UCA 61850-9-2LE
compatible stream on the SAM600 system bus. With PCM600, streams can be
created with the SV Configurator Tool and are assigned to the available IEC 61850
access points of a SAM600 system.
Usage of electrical or optical communication ports
SAM600 modules can be placed in a single marshaling kiosk or in separate
housings in order to achieve close proximity to primary equipment (see Figure 5)
and minimize cabling to primary apparatus.
