System functionality

Scalable SAM600 system
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 up to three independent IEC 61850 access points are available 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
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.
Merging and bridging of IEC/UCA 61850-9-2LE streams
With a SAM600 system, IEC/UCA 61850-9-2LE based streams that consist 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 "bridged" 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
apparatus.
When installed in the same kiosk, a SAM600 system bus is typically realized through 100BASE-
TX ports. When installed in different compartments in the field, the system bus through which
SAM600 modules communicate with each other must be realized by 100BASE-FX ports.
Binary inputs for process supervision
Binary inputs on SAM600 modules are used for secondary system supervision. The inputs are
pre-assigned with test switch indication (SAM600-VT and SAM600-CT) and fuse failure
indication (SAM600-VT only). Information acquired through these inputs is reflected in the
quality information in the IEC/UCA 61850-9-2LE streams.
The polarity and the input level of the binary inputs are configurable. If the binary inputs of a
SAM600 module are not connected, their input processing can be disabled in the Parameter
Setting Tool of PCM600.

Section
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.
