The REX640 protection relay together with the Substation
Management Unit COM600S constitutes a genuine IEC 61850
solution for reliable power distribution in utility and industrial
power systems. To facilitate the system engineering, ABB's
relays are supplied with connectivity packages. The
connectivity packages include a compilation of software and
relay-specific information, including single-line diagram
templates and a full relay data model. The data model includes
event and parameter lists. With the connectivity packages, the
relays can be readily configured using PCM600 and integrated
with COM600S or the network control and management
system MicroSCADA Pro.

REX640 offers native support for IEC 61850 Edition 2 including
binary and analog horizontal GOOSE messaging. In addition, a
process bus enabling sending and receiving of sampled values
of analog currents and voltages is supported.

Unlike the traditional hardwired, inter-device signaling, peer-to-
peer communication over a switched Ethernet LAN offers an
advanced and versatile platform for power system protection.
Among the distinctive features of the protection system
approach, enabled by the full implementation of the IEC 61850
substation automation standard, are fast communication
capability, continuous supervision of the protection and
communication system's integrity, and flexible reconfiguration
and upgrades. This protection relay series is able to optimally
use the interoperability provided by the IEC 61850 Edition 2
features.

At substation level, COM600S uses the data content of the bay
level devices to enhance the substation level functionality.

COM600S features a Web browser-based HMI, which provides
a customizable graphical display for visualizing single-line
mimic diagrams for switchgear bay solutions. The Web HMI of
COM600S also provides an overview of the whole substation,
including relay-specific single-line diagrams, which makes
information easily accessible. Substation devices and
processes can also be remotely accessed through the Web
HMI, which improves personnel safety.

In addition, COM600S can be used as a local data warehouse
for the substation's technical documentation and for the
network data collected by the devices. The collected network
data facilitates extensive reporting and analyzing of network
fault situations by using the data historian and event handling
features of COM600S. The historical data can be used for
accurate monitoring of process and equipment performance,
using calculations based on both real-time and historical
values. A better understanding of the process dynamics is
achieved by combining time-based process measurements
with production and maintenance events.

COM600S can also function as a gateway and provide
seamless connectivity between the substation devices and
network-level control and management systems, such as
MicroSCADA Pro and System 800xA.

The GOOSE Analyzer interface in COM600S enables the
monitoring and the analysis of the horizontal IEC 61850
application during commissioning and operation at station
level. It logs all GOOSE events during substation operation to
enable improved system supervision.
