1. GENERAL
This manual describes the features of the SE-330,
SE-330AU, and SE-330HV IEC 61850 interface. Unless
otherwise indicated, “SE-330”refers to all three monitor
series in general. The optional IEC 61850 interface
includes Manufacturing Message Specification (MMS)
and Generic Object Oriented Substation Events (GOOSE)
elements. MMS Buffered and Unbuffered Report Control
Blocks are supported with user-definable Data Sets. Two
GOOSE Control Blocks and 16 GOOSE Network Inputs
are available to provide high speed peer-to-peer signaling.
Three hardware configuration options are available to
provide redundant network connections: Dual RJ45, Dual
Fiber SC, and Single RJ45/Single Fiber SC.
The IEC 61850 interface is configured using the
SE-MON330 configuration software (version 3.2 or later).
Modbus/TCP is included to support configuration of the
SE-330 over the network. For more information on the
Modbus/TCP interface, refer to the SE-330 Series
Modbus/TCP manual.
1.1 CONFIGURATION SOFTWARE
The IP, SNTP and IEC 61850 settings are configured
using SE-MON330 through the front-panel USB interface.
To download SE-MON330, please visit
www.littelfuse.com/se-330. For information on how to
connect SE-MON330 to the SE-330, please refer tothe SE-
MON330 help file found in the Help –Contents menu.
2. NETWORK CONFIGURATION
IP and SNTP settings are configured on the
SE-MON330 Details Page tab as shown in Fig 1.
2.1 ETHERNET PORTS
Two Ethernet interface types are available for the
SE-330:
•10/100 BASE-Tx full/half duplex Auto-MDIX
RJ45
•100 Mbps fiber SC
Three combinations of these interface types are
available:
•Dual RJ45
•Dual Fiber SC
•Single RJ45 / Single Fiber SC
See Figs. 2, 3, and 4.
2.2 IP SETTINGS
When connected to the SE-330 with SE-MON330, the
IP settings can be found in the Details Page tab in the
Network Parameter section. The IP address, subnet mask
and gateway can be configured for each network interface.
Default values for these settings are listed in Table 1.
TABLE 1. DEFAULT IP SETTINGS
INTERFACE 1
IP Address
192.168.1.100
Subnet Mask
255.255.255.0
Gateway
0.0.0.0
INTERFACE 2
IP Address
192.168.2.100
Subnet Mask
255.255.255.0
Gateway
0.0.0.0
For troubleshooting network connections, the SE-330
supports ICMP ping requests.
Note: Ensure that each port is configured with a unique
IP address even if not used.
2.3 SNTP SETTINGS
When connected to the SE-330 with SE-MON330, the
SNTP Settings can be found in the Details Page tab in the
SNTP Parameter section. SNTP Enable, NTP Server IP
Address, Poll Period, and Timeout can be configured.
Enable the SNTP Client and set the NTP Server IP
Address to the address of the system NTP Server to
synchronize the SE-330 to the system time. For
troubleshooting connection problems with the NTP Server,
monitor the SNTP Client status. The status indicates
problems such as NTP Server not found, NTP Server not
running, and timeout.
The Poll Period is the time between queries to the NTP
server. The default value is 60 s, which is typically
sufficient to maintain time synchronization to 1 ms
accuracy, but it can be configured for periods as low as
1 s.
The Timeout is the maximum time that the SNTP Client
will wait for a response from the NTP Server. The default
value is 5 s, and the minimum time is 1 s. Ifa request fails,
no change is made to the SE-330 internal clock.
2.4IEC 61850 CLIENTS
The SE-330 IEC 61850 interface supports a total of four
simultaneous client connections. Client connection
requests are accepted in the order they are received and are
available on either network interface.

3. IEC 61850 CONFIGURATION
The SE-330 IEC 61850 interface can be configured with
SE-MON330. The configuration can be loaded from an
SE-330 or from an ICD configuration file that has been
generated in an IEC 61850 system design tool. When the
IEC 61850 configuration is ready in SE-MON330, it can
be written to the SE-330 or to an ICD file.
IEC 61850 settings are visible in the IEC 61850 tab of
SE-MON330 when it is connected to an SE-330 with the
optional IEC 61850 interface. When SE-MON330 is first
connected, the IEC 61850 fields are empty. The
configuration can be loaded from the SE-330 by clicking
“Load From SE330” or from an ICD file by clicking “Load
From ICD File”. The configuration can then be
modified and written to the SE-330 by clicking “Write to
SE330”, or to an ICD file by clicking “Write to ICD File”.
After writing the configuration to the SE-330, cycle SE-
330 control power for the settings to take effect.

3.2 REPORT CONTROL BLOCKS
The IEC 61850 interface includes four Buffered Report
Control Blocks (RCB) and four Unbuffered Report Control
Blocks. To configure the RCB’s, select the
IEC 61850 RCB tab in SE-MON330 as shown in Fig. 6.
RCB’s are used for data reporting to clients. Changes
made to the RCB configuration through SE-MON330
become the default settings. The RCB can be enabled or
disabled through the IEC 61850 interface.
The Data Set to be reported by the RCB is selected in the
Data Set field. Fixed or user-defined Data Sets can be
selected. See Section 3.3. The Report ID is a text
description of the RCB and has a maximum size of 64
characters.
The Config Revision allows the user to maintain control
of the configuration revision. In a commissioned system,
if the RCB configuration changes, the Config Revision
should be incremented.
For buffered RCB’s, the Buffering Time can be
configured. The default time is 1,000 ms. The minimum
time is 0 ms, and the maximum is limited only by the
64 kB buffer memory.
The RCB can be configured to generate a report at
specific intervals by setting the Integrity Period to a value
other than 0 ms and enabling the Integrity Triggering
Option.
RCB’s can be configured to generate data reports under

3.3 DATA SETS
Data Sets are used to group elements of the MMS data
model for use in RCB’s and GOOSE Control Blocks
(GCB). Data Sets are viewed and edited using
SE-MON330 in the IEC 61850 Data Sets tab as shown in
Fig. 7.
The IEC 61850 interface includes three fixed Data Sets,
and 29 user-definable Data Sets. The three fixed Data Sets
are:
•LLN0$DS1_Measurement Data
•NGR Voltage
•NGR Impedance
•Ground-Fault Current Meter Values
•LLN0$DS2_Record Data
•Event Record Data for all events that are
recorded by the SE-330
•LLN0$DS3_GOOSE
•Ground-Fault Start
•Ground-Fault Operate
•Resistor-Fault Start
•Resistor-Fault Operate
•Remote Trip Status
The GCB’s are configured to use the LLNO$DS3
GOOSE Data Set. Refer to Section 3.4.1 for more
information on the GCB’s. For a detailed description of
the fixed Data Sets, refer to Section 4.1.2.
User-defined Data Sets can be added through SE-
MON330. To add a Data Set open the Data Sets tab and
click the “+” button. This will open the Data Set Properties
window as shown in Fig. 8. In the Data Set Properties
window, assign the Data Set to a Logical Node, give the
Data Set a unique name and choose data elements to
include in the Data Set. Data elements are chosen from the
data-model tree on the left, and can be added to the list on
the right by clicking the arrow buttons. Up to 30 data
elements can be added. Only data elements with a
functional constraint of ST orMX can be included in a Data
Set. When a data element has been added to the list on the
right, it can be moved up or down in the list with the up and
down arrow buttons, or removed from the list with the “X”
button.

3.4 GOOSE SETTINGS
IEC 61850 GOOSE is used to provide network trip and
alarm signaling in place of or in addition to traditional relay
connections. The GOOSE configuration is viewed and
edited in the IEC 61850 GOOSE tab as shown in
Fig. 9.
GCB’s are configured to publish GOOSE data on the
system network. GOOSE Network Inputs are configured
to subscribe to GOOSE data that is available on the system
network.
3.4.1 GOOSE CONTROL BLOCKS
To support the redundant network interfaces on the
SE-330, two GCB’s are available. The GCB’s can be
independently enabled and can be configured to transmit
on one or both network interfaces.
Both GCB’s transmit the LLN0$DS3_GOOSE Data Set,
which includes the Ground-Fault Start, Ground-Fault
Operate, Resistor-Fault Start, Resistor-Fault Operate and
Remote Trip status. These data elements support network
signaling of all SE-330 trip conditions.
The GCB’s are configured independently with options
for the Destination MAC address, VLAN settings,
Application ID, GOOSE ID, Test flag, and Network
Interface. The Configuration Revision is not configurable
and is fixed at 1.
The Destination MAC address, Application ID and
GOOSE ID are used to uniquely identify the source of the
GOOSE data. Each of these values is assigned by the
system designer in consideration of all GOOSE publishers
and subscribers on the network.
The 48-bit MAC address is typically marked as a
multicast address by setting the least significant bit of the
most significant byte to 1.
The Application ID can be any integer value between 1
and 4095.
The GOOSE ID is a user-definable text identifier. It can
contain alpha-numeric characters and underscores and has
a maximum length of 64 characters.
VLAN ID and VLAN Priority configure Virtual LAN
routing of GOOSE messages through the network. VLAN
parameters are assigned by the system designer in
consideration of all other traffic on the system network. To
disable VLAN support, set the VLAN ID and VLAN
Priority to 0.
The GCB can be configured to assertthe Test flag which
informs subscribers totreat the GOOSE data as a test. How
test data is handled in the subscriber is dependent on the
specific device, but test data will typically not be used in a
trip decision.
The Network Interface can beset toInterface 1, Interface
2 or Interface 1 and 2. When set to Interface 1 and 2,
identical GOOSE messages are transmitted simultaneously
on both SE-330 network interfaces.
The reception of duplicate GOOSE messages by a
subscriber can cause undefined behavior, so the redundant
network topology must be considered when configuring
the GCB’s.
When connected to a subscriber with redundant network
interfaces through a fully redundant network, there is no
danger of duplicate GOOSE messages being received on
either of the subscriber’s network interfaces. In this case,
a single GCB can be configured to transmit messages on
Interface 1 and 2. This configuration can be supported in
the subscriber by configuring two Network Inputs, one for
each network interface.
When connected to a subscriber with redundant network
interfaces through a network on which the GOOSE
messages can cross to either side of the network and be
received on both network interfaces of the subscriber, the
GCB configuration depends on the behavior of the
subscriber. In this case, two GCB’s can be configured with
unique GOOSE configurations to be transmitted on
different network interfaces.
3.4.2 GOOSE NETWORK INPUTS
Up to 16 GOOSE Network Inputs are supported. The
Network Inputs drive the Remote Trip function within the
SE-330.
Network Input parameters must be configured to match
the desired GOOSE message. The Destination MAC
address, Application ID, Config Revision, and GOOSE ID
must all match the corresponding fields in the GOOSE
message.
The Network Inputs require a Boolean data attribute.
The Boolean data attribute can be received as a single
Boolean value, or as a member of a Boolean bit-string.
Configure the Data Index to the index of the desired
Boolean value in the GOOSE message. The first data
element is index 0. If the value is a Boolean bit-string,
configure the BitIndex tothe index ofthe desired bit within
the bit-string starting with index 0, otherwise set Bit Index
to 0.
The Boolean data can be inverted before it is used in the
trip decision by setting Inverted to Yes.
For troubleshooting Network Input configurations, the
status of each Network Input can be viewed in the
IEC 61850 GOOSE tab under NI Status. The Network
Input status values are listed in Table 5. The Network Input
is colored green when the received value will not cause a
Remote Trip, red when the received value will cause a
Remote Trip, and yellow when the received value will be
ignored due to the Network Input configuration.

FIGURE 9. SE-MON330 IEC 61850 GOOSE Tab.
The Network Inputs are combined in a logical OR
operation to drive the Remote Trip function within the SE-
330. Disabled Network Inputs and Network Inputs with a
status other than OK are not included in the trip decision.
The Boolean equation for the trip status of each Network
Input is shown in Equation 3.1:
Equation 3.2 is the Boolean equation for the
combination of the Network Inputs in the Remote Trip
decision:
