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.

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.

Supported ABB solutions

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.

The Operator pages can be used as such or customized

according to the project’s requirements using Graphical Display

Editor (GDE) within the PCM600 software tool. The Engineer

pages are fixed and cannot be customized.

The Operator pages can be scrolled either by tapping the Home

button or by swiping the actual pages. The Engineer pages are

accessible by touching the upper horizontal section of the

screen.

The LHMI is an accessory for the relay which is fully operational

even without the LHMI. The relay communication card has a

dedicated port where the LHMI is connected using an RJ-45

connector and a CAT6 S/FTP cable. The LHMI can be

connected to the relay also via station communication network

if a longer distance is required between the relay and the LHMI.

Additionally, the LHMI contains one Ethernet service port with

an RJ-45 connector and one USB port. The service port can be

used for the PCM600 connection or for Web HMI connection.

Data transfer to a USB memory is enabled via the USB port. By

default the USB port is disabled and has to be taken into use

with a specific parameter.

Local HMI

The LHMI uses rugged 7-inch high resolution color screen with

capacitive touch sensing technology. The user interface has

been carefully designed to offer the best situational awareness

to the user. Visualization of the primary process measurements,

events, alarms and switching objects’ statuses makes the local

interaction with the relay extremely easy and self-evident. The

LHMI provides a control point for the selected primary devices

via pop-up operator dialogs.

Additionally, the LHMI supports the engineer during the relay’s

testing, commissioning and troubleshooting activities. The

information, traditionally accessible through different paths

within the menu structure, is provided in collectively grouped

and visualized format.

REX640 offers comprehensive base functionality. However, it is

possible to further adapt the product to meet special installation

needs by including any number of the available optional

application packages into a single REX640 relay. For the

selected application packages, the functionality can be

extended by including the related add-on package. The

REX640 connectivity package guides the engineer in optimizing

the application configuration and its performance.

Description

REX640 is a powerful all-in-one protection and control relay for

use in advanced power distribution and generation applications

with unmatched flexibility available during the complete life

cycle of the device – from ordering of the device, through

testing and commissioning to upgrading the functionality of the

modular software and hardware as application requirements change.

The modular design of both hardware and software elements

facilitates the coverage of any comprehensive protection

application requirement that may arise during the complete life

cycle of the relay and substation.

REX640 makes modification and upgrading easy and pushes

the limits of what can be achieved with a single device.

When IED configurations are changed using IET600. some preparations are

required when a project is started and the 615 series IED data model is imported to

the tool for the first time.

• The default 615 series IED SCL export from PCM600 contains five default

client definitions, “Client1”…”Client5”, which are used by all the RCBs.

MicroSCADA and COM600 clients can use the client definitions directly. If

other clients need to be added to the IET600 project, import the ICD file

describing the client data model to the project and attach the file to the same

IEC 61850 subnetwork in the Communication tab.

• Create the bus connections for the IEC 61850 clients.

All data sets must be configured under the logical node LLN0 and must be

provided with names unique within the IED. In 615 series IEDs there are a

maximum of four GOOSE control blocks allowed, which effectively limits the

relay to four data sets for GOOSE as there is a one-to-one correspondence between

the GOOSE control blocks and GOOSE data sets. Typically it is sufficient to

define a single data set and control block for an application. However, it is

recommended to use a separate data set and corresponding control block for analog values.

Importing a new IEC 61850 client

Adding a new IEC 61850 client to an IET600 project is a two-step operation. The

client must be first created using the Create New IED function, after which the

Update IED function can be used to import the related ICD (or CID) file.

1. To create an IED, click the IEDs tab in the navigation pane.

2. Click the root node in the IED tree.

3.Right-click the node and click Create New IED on the shortcut menu.

Creating a GOOSE data set

Define the sending data set used by the GOOSE control block. With the 615 series

IEDs, the sending GOOSE data set can have at maximum 20 data attributes to

minimize the message handling load in receiver and sending IEDs.

All data sets must be configured under the logical node LLN0 and must be

provided with names unique within the IED. In 615 series IEDs there are a

maximum of four GOOSE control blocks allowed, which effectively limits the
