Section 2 Safety information
GUID-7CDA9FB7-5CD6-4BD5-A1D2-AAB8E7BF87A3 v3
Dangerous voltages can occur on the connectors, even though the auxiliary
voltage has been disconnected.
Non-observance can result in death, personal injury or substantial property
damage.
Only a competent electrician is allowed to carry out the electrical installation.
National and local electrical safety regulations must always be followed.
The frame of the IEDs has to be carefully earthed.
Whenever changes are made in the IEDs, measures should be taken to avoid
inadvertent tripping.
The IEDs contain components which are sensitive to electrostatic discharge.
Unnecessary touch of electronic components must therefore be avoided.

Section 3 Interbay bus functions
GUID-FC8C1289-F943-4E92-A50E-BDA7281A5337 v1
3.1 Introduction
GUID-7A41F2A2-F366-4D30-9D76-BB6279380110 v3
An interface is available for connecting the numerical busbar protection to a station
automation system or station monitoring system (SCS/SMS).
For an overview of REB500’s communication interfaces, see the Operation manual .
In contrast to feeder control and protection bay units, REB500 is equipped with only a single
interbay bus interface via which all the REB500 bay units in the entire station communicate.
This has to be taken into account by the various bus protocols.
This document applies for IEC 60870-5-103. However, Section 3 of this
document also contains information of a second IBB using IEC 61850-8-1 if
configured.
3.2 Basic configuration
GUID-A112B99B-E8BF-4750-8E26-D9C9BD9F6048 v3
The fourth octet in the Data Unit Identification field of an ASDU determines the common
address of ASDU. It normally has to be the same as the station address on the link layer.
Exceptions are permitted where additional common ASDU addresses are needed because of
multiple instances of functions.
In case of REB500, this exception allowed in the IEC recommendation is used to be able to
address the Central Unit and the Bay Units via a single physical connection.
Common Address of ASDU – CAA
Basic setting:
0 Central Unit
1-60 Bay Units
255 Global address
The dialog for configuring the communication is accessed by selecting HMI500
Configuration/Communication/SCS Configuration.

3.3 Configuring IEC 60870-5-103 IBB
GUID-605B1ACD-79EB-4C0A-8839-331FD573E41B v1
For changes in status generated by REB500 to be transferred as events to an SCS/SMS, the
corresponding signals must be configured by selecting them in HMI500 Configuration /Binary
module and making the settings in the Event configuration section of the Details dialog box.
To which IBB an event is sent is determined by selecting the appropriate check box IBB 1 or IBB
2 when configuring the signal.
As the 61850 model is implemented as defined by the standard, no custom assignments can
be made for the IBB associated with 61850.

Figure 4: Configuring signals as events
Diagnostic and system events are always available for transfer whichever protocol is in use
and cannot be configured.
The IEC 60870-5-103 section only appears when the protocol is configured.
3.4 Transfer of differential current values
3.4.1 The delta/dead band algorithm GUID-85BE2C1A-DD67-4564-99E1-CF504CBD06D7 v1
To keep the load on the IBB as low as possible, the bus zone differential currents are checked
cyclically, but only actually transferred via the bus if the value has changed.

IEC18000308 V1 EN-US
Figure 5: Transmitted values and the zero limit
To stabilize the display during normal operation, differential currents below the zero limit
(dead band) count as zero and are transferred as such.
Providing the condition for transmitting a current value is fulfilled, all the differential currents
belonging to the respective zone are sent to the SCS/SMS.
Example 1
sum = sum + |current – last|
if sum > delta then
sum = 0
if current < deadband then
current = 0
endif
send current
endif
last = current
The system continuously performs the above algorithm: It adds up the absolute difference
between the last two measurements (current and last) since the last status update was sent
(sum).
As soon as sum is greater than the threshold delta a new event will be sent with the current
value. If this value is below the deadband threshold, the value 0 will be sent instead.
3.4.2 Configuring the SCS differential current parameter
GUID-DF29CA42-6DDD-459D-A610-175B597D83C9 v2
The precise conditions for sending differential currents to the SCS can be set by selecting

Section 4 IEC 60870-5-103
4.1 Introduction
GUID-011906E4-AFE3-4962-825C-7134F3CC9EA5 v1
Busbar protection is not one of the types of protection defined in IEC 60870-5-103.
Nevertheless, the commands and signals of the REB500 system are modeled as far as possible
on functions defined in the IEC recommendation. The functional scope of the station protocol
is therefore reduced. The backup protection functions breaker failure, time-overcurrent and
end fault that are optionally available with REB500 are also supported.
According to the IEC recommendation, usage of the private range is only permitted with
regard to the compatibility of existing devices. For this reason, additional REB500 functions
that are not defined in the recommendation were implemented according to the future-
oriented generic part of IEC 60870-5-103.
REB500 also optionally provides a private range.
Refer to IEC 60870-5-103 for an explanation of the various abbreviations.
4.2 General functions
GUID-B95181CD-4E96-4569-BA0A-5D1EF56CA1D1 v3
The tables below define the functional scope of REB500 according IEC 60870-5-103. The
