Protocol Structure

Description

DNP3 has a graded architecture. Instead of the OSI model, however, a simplified 3-layer model suggested bythe IEC is used. This model was named Enhanced Performance Architecture (EPA) by the IEC. However,DNP3 adds a 4th layer, a pseudo transport layer, with which messages can be segmented. The usedgraphics were taken from the DNP3-Spec-V1-Introduction-20071215.pdf standard.

Physical Layer

The physical layer mainly deals with the physical media through which the protocol is transferred. The phys-ical layer deals with, for example, the condition of the media (free or occupied) and the synchronizationthrough the media (start and stop).

1.1

1.1.1

1.1.2

Protocol Characteristics1.1 Protocol Structure


DNP3 most frequently uses a simple, asynchronous serial transmission like RS232 or RS485 with physicalmedia like pilot wires and optical fiber. Moreover, the transmission can take place through Ethernet.

[dwdalila-030314.vsd, 1, en_US]

Figure 1-2 Physical Layer

Data-Link Layer

The data link layer manages the logical connection between the transmitter and the receiver of the informa-tion and improves the fault tolerance of the physical line. This is achieved with DNP3 by starting every datatransmission package with a data head, and a 16 bit CRC (cyclic redundancy check) is executed for every 16bytes of the package.A package is a part of the complete message transferred through the physical layer. The maximum size of adata package is 256 bytes. Each package has a 16-bit source address and a 16-bit target address, which canalso be a general address (0xFFFF).

1.1.3



The 10-byte data link layer head contains: The address information A 16-bit start code The frame length A data link control byteThe data link control byte displays the cause of the data transmission and the status of the logical connection.The data link control byte can have the following values: ACK (data link confirmation) NACK (negative confirmation) Connection needs to be reset Connection is reset Data link confirmation from the package requiredIf a data link confirmation is needed, the receiver must respond with an ACK data package if the package wasreceived and the CRC checks were successful. If no data link confirmation is requested, no response isrequired.

Pseudo Transport Layer

The pseudo transport layer segments application messages in multiple data transmission packages.The pseudo transport layer implements an individual byte function code for every package. The byte functioncode displays what the data transmission package is: The 1st package of a message The last package of a message Both (for individual message packages)The function code delivers a running package number. This subsequent package number is increased witheach package and allows the receiver's transport layer to analyze the package.

[dwtrfnct-030314, 1, en_US]

Figure 1-3 Pseudo Transport Layer

Application Layer

The application layer responds to received messages and creates messages based on the necessity andavailability of the user data. As soon as messages are available, they are sent to the pseudo transport layer.The messages are segmented here, sent to the data link layer and transferred through the physical layer.If the data that is to be sent is too large for an individual application message, a number of applicationmessages can be created and sent in a sequential manner. Each message is an independent applicationmessage. Their only connection with each other is the label in all messages that says that more messageswill follow. Only the last message does not contain this label. Each application message refers to a fragmentdue to the fact that the user data may be fragmented. A message can thus be a single fragment message ora multi-fragment message.Application packages from DNP3 slaves are normally responses to queries. A DNP3 slave can also send amessage without a request, thus, an unsolicited response.As in the data link layer, application fragments can be sent with a confirmation request. An application confir-mation indicates that a message was not only received, but rather it was also syntactically analyzed without

1.1.4

1.1.5



any errors. A data transmission confirmation or an ACK indicate only that the transmission package wasreceived and that the CRC checks were error-free.Each application package begins with an application layer header, followed by one or more object heads/object data. The application layer header contains an application control code and an application functioncode.If one of the following conditions is fulfilled, then the application control code contains labels: The package is a multi-package message. An application layer acknowledgment is requested for the package. The package is not requested.The application control code contains a continual application layer number. With this application layernumber, the receiving application layer can recognize alien packages or lost packages.The application function code in the header of the application layer indicates the cause or the requested func-tion in the message. While DNP3 allows a number of data types in a single message, it also allows only anindividual query for a data type within the message.Examples for application function codes include: Acknowledgments for confirmation on the application layer Read and write Select and execute (SBO (select before operate), controls) Direct control (for switching objects without SBO) Save and delete (for counters) Restart (both cold and warm) Enable and disable non-requested messages Selection of the classesThe application function code in the header of the application layer applies for all object headers. Thus, theapplication function code applies for all data within the message package.

Ethernet Services

Activation and Ability to Switch Off Services

The following additional Ethernet services are available for the integrated Ethernet interface (Port J) of thedevice: DIGSI 5 protocol (always available) DCP SNTPThe following additional Ethernet services are available for the Ethernet communication module: DIGSI 5 protocol (always available) DCP SNMP SNTP SUP Ethernet (for connecting external analog units) Homepage RSTP, PRP or HSRWith the exception of the DIGSI 5 protocol, all additional Ethernet services can be switched on and off foreach Ethernet interface on the device. As a result, you can decide for yourself under security aspects whetherthe device should react to SNMP access or not.Additional information on SUP Ethernet is available in the following manuals: SIPROTEC Transformer Differ-ential Protection 7UT85 7UT86 7UT87, SIPROTEC Distance Protection, Line Differential Protection, andOvercurrent Protection for 3-pole Tripping 7SA84, 7SD84, 7SA86, 7SD86, 7SL86, 7SJ86, and SIPROTECDistance Protection, Line Differential Protection, and Switch Management for 1-pole and 3-pole Tripping7SA87, 7SD87, 7SL87, 7VK87.

Activating Ethernet Service

To switch on an Ethernet service in the device, activate the corresponding check box in the channelsettings of the Ethernet communication module or for the integrated Ethernet interface.

Deactivating Ethernet Service

To switch off an Ethernet service in the device, deactivate the corresponding check box.You will find additional information regarding network security in the Security Blueprint.

DCP

The Discovery and Basic Configuration Protocol (DCP) is used for automatic recognition of devices without aconfigured IP address. DIGSI 5 can find all SIPROTEC 5 devices in the network using DCP.DCP is not required for the functionality of communication protocols. The protocol can however in parallel beconfigured for a DIGSI Life List functionality.The DIGSI Life List shows the connected devices. You can monitor and process these devices via the DIGSILife List.If you also desire a DIGSI Life List functionality through the LAN, then you must activate DCP.If you create a new device in DIGSI or add an Ethernet communication module to the device, DCP is acti-vated. If you change this recommended default and want to switch off the DIGSI Life List functionality in thedevice, deactivate the DCP check box in the channel settings of the Ethernet communication module or forthe integrated Ethernet interface.

SNMP

Settings for SNMP

SNMPv3 (SNMP - Simple Network Management Protocol) is implemented in all Ethernet communicationmodules.As default, SNMP is deactivated. If you want to switch on SNMP in the device, activate the SNMP check boxin the channel settings of the Ethernet communication module.Then, if necessary, you can set the UDP port where the SNMP agent (Ethernet communication module)receives the queries. The standard setting for the UDP port is 161 and normally should not be changed.

Parameter Name SettingsUDP port for SNMP agent UDP port of the SNMP agent (device)

Standard setting = 161

SNMP allows the state query of these modules. For the display of MIB information (MIB Management Infor-mation Base), an MIB browser and the description files are required.

SNTP

The Simple Network Time Protocol is used to synchronize clocks via the Internet. With SNTP, clientcomputers can synchronize their clocks with a time server via the Internet.SNTP is available for the integrated Ethernet interface (Port J) of the device:SNTP uses UDP port 123 (UDP - User Datagram Protocol).

DHCP

The Dynamic Host Configuration Protocol (DHCP) enables a client, in this case the Ethernet interface, toaccess IP address and configuration data from a DHCP server. In this case, a DHCP server has to be avail-able in the network. If DHCP is activated, you do not have to configure the Ethernet interface network settingsyourself.

RSTP

Description

The Rapid Spanning Tree Protocol (RSTP) serves for the reorganization of the network structure in the eventof an error. In other words, RSTP reroutes the data to another path after the failure of a network path.

PRP

PRP (Parallel Redundancy Protocol) is a redundancy protocol for Ethernet networks. This protocol is speci-fied in the norm IEC 62439-3. In comparison to conventional redundancy procedures, for example, RSTP(Rapid Spanning Tree Protocol, IEEE 802.1D-2004), PRP offers a switchover without interruptions. Thisavoids a dead time in the event of a fault, and thus the highest availability.Previous redundancy methods are based on mechanisms where the power-system components (switchesand bridges) agree with each other and find the best communication path for normal operation.In the event of a fault, for example, in a cable, an optical fiber, or in case of a switch failure, the interruption isdetected and alternative paths are found in the network and connected. No communication can take placeduring this switching procedure. Depending on the size and on the configuration of the Ethernet network, thisstate can last for 10 ms up to around 1 s. A protocol extension in the end device is not necessary in this casebecause the protocol is implemented in the switches.PRP adopts a different approach.

1.2.3

1.2.3.1

1.2.4

1.2.5

1.2.6

1.2.6.1

1.2.7



The redundancy procedure is generated in the end device itself. The procedure is simple: The redundant enddevice has 2 Ethernet interfaces with the same address (DAN, Double Attached Node). Then, the same indi-cation is sent twice, with PRP (parallel) via 2 separated networks. Both indications are unambiguously identi-fied with a sequence number.The receiver takes the information that arrives first, stores the ID of the information in a duplicate filter usingthe source address and the sequence number of the information. Thereby, the receiver recognizes the 2ndredundant information and discards it.. This redundant information is then discarded.If the 1st indication is missing, the 2nd indication with the same information arrives via the other network. Thisredundancy avoids a switchover of the network and is therefore a redundancy without interruption.The end device does not forward any indication to the other network.Since this procedure is realized in the Ethernet layer (same MAC address), it is transparent and can be usedby all Ethernet informative data protocols (IEC 61850, DNP, other TCP/IP based protocols).In addition, it is possible to use one of the 2 networks for the transmission of not redundant indications. To doso, connect a SAN (Single Attached Node) device to a network. In this way, a PRP end device can communi-cate with a SAN end device (in a not redundant way). If you wish to connect a SAN end device in a redundantway to a PRP system, use a REDBOX (redundancy box). This REDBOX provides PRP functionality exter-nally as an in-line device. However, the PRP procedure also presents a disadvantage: You are buying theincreased redundancy function at the cost of a duplicate network (2x switches, cables).

iiNOTE

Both networks must not be connected as this causes Ethernet double addressing and this can result inmalfunctions!

There are 2 versions of PRP: PRP-0 and the successor PRP-1. Siemens implements PRP-1.

HSR

Like PRP, HSR (High Availability Seamless Redundancy Protocol) is specified in the norm IEC 62439-3. Bothprotocols provide a redundancy without switchover.The basic function can be found in the definition of PRP. With PRP, the same indication is sent via 2 sepa-rated networks. In contrast to that, with HSR, the idication is sent twice in the both directions of the ring. Thereceiver gets the indication via 2 ways in the ring, takes the 1st indication, and discards the 2nd (see PRP).Whereas a PRP end device does not forward any indication, an HSR node has a switch function. Thus, theHSR node forward indications in the ring that are not addressed.In order to avoid circling indications in the ring, special measures are defined in the case of HSR. SAN(Single Attached Node) end devices can only be connected with a REDBOX in the case of HSR.PRP systems and HSR systems can be coupled in a redundant way with 2 REDBOXES.

Transfer through Ethernet

Requirements for the Physical, Transport, and Application Layers

The transmission through Ethernet takes place according to the same specifications as transmission throughserial connections. Only the method for the time synchronization through the network must be changed. Allrequirements in the other protocol layers can be applied. Connection packages are transported in anunchanged manner through the Ethernet protocol suite under the control of the data link layer.

Acknowledgments

If the SIPROTEC devices communicate through Ethernet, they must not work with confirmations from thephysical layer (CONFIRMED_USER_DATE). If necessary, the confirmations must be used by the applicationlayer. For confirmations of the application layer, there is no difference between IP networks (IP = Internetprotocol) and serial channels.

Message Transmission

As soon as the data link layer has established a TCP connection (TCP = Transmission Control Protocol) or aport for UDP datagrams (UDP = User Datagram Protocol) has been delivered, the physical layer of DNP3 cantransmit packages as needed. The type of query, and if it is requested or not, does not depend on the type ofconnection.A typical case for a DNP3 master is as follows: A TCP connection is established with a device. A class 1, 2, 3, 0 request is executed once. The data integrity is checked. The non-requested transmission is made possible. Then work is continued in this mode.

Fault Record Transfer

Configuration of a Fault Record

The content of a fault is parameterized as described in the Operating manual.

iiNOTE

If the fault record for the serial DNP3 protocol is read via the DNP3 master, Siemens recommends 5seconds as the setting for the maximum length of a fault (default setting in device). If the fault record islonger the connection to the device could be broken because large data volumes have to be transferredserially. This constraint does not apply for DNP3 TCP (Ethernet).

Transferring a Fault Record

The file transfer can be used to transfer a fault record (Object 70). The Rcd Made message is used to querythe availability of the fault record. When the message is mapped and there is a new fault in the device themessage is transferred. Cyclical reading of the directory is also possible. If there are files in the directory thenthere are also fault records. Specifically, the transfer takes place as follows:The following steps are required to read the directory: Reading of the directory with File Transport Object (obj 70 var 7) Waiting for the response If the read operation was successful, the master station increases the block number and reads the next

block.

If the status indicator Last is set in the response, the master station closes the file with File OperationStatus Object (obj 70 var 4).

Every fault record is identified by an existing file. The following information is transferred for this: File Name Offset File Name Size File Type File Size Time Of Creation Permissions Request ID File NameThe master station can now select the required fault. The transfer takes place in the same manner as withreading the directory.

Communication-Module Selection

The devices are delivered equipped with communication modules. You can install and replace communica-tion modules afterwards. When doing so, you must ensure that both the protocol firmware and the parameter-ization of the protocol are first transferred through DIGSI 5.Select the communication modules from the library in the Hardware Editor working area in DIGSI 5. The typeof communication protocols to be used is the deciding factor when selecting the communication module.The serial DNP3 protocol runs on serial modules (USART = Universal Synchronous/Asynchronous Receiver/Transmitter) with electrical RS485 interfaces or optical 820-nm interfaces. The module can have 1 or 2 inter-faces. The DNP3 protocol through TCP runs on all Ethernet modules.Operating the DNP3 protocol through the integrated Ethernet interface (Port J) is not possible.In the Project Tree, select the Devices and Networks area.

Communication-Module Configuration

The installed communication modules are configured in the Hardware Editor working area in DIGSI 5.There are modules with 1 or 2 serial interfaces. Here, a module with 2 RS485 interfaces is used.

[scdnpmpr-251110-01.tif, 1, en_US]

Figure 3-2 Serial Communication-Module Configuration

Each communication channel of a communication module must be configured individually.Highlight the channel to be configured in the Device view. The protocol types are listed in the working-areawindow that opens. These can be routed on the highlighted channel.Depending on the type of communication module, one or more protocols can be routed per channel.However, the DNP3 protocol cannot be parameterized jointly with another protocol on one channel. TheDNP3 protocol can be configured twice on 2 channels of a module or on one channel of a different modulealso in the device. Through this, the protocol can be executed redundantly, also on different modules.DIGSI defines the selection of the combinable protocols. The combination of the individual modules is visiblein DIGSI.With the selection of the communication channel, the parameters required for the DNP3 protocol are shown.The following images show the settings for the serial connection and the settings for the communicationthrough Ethernet.You can find more detailed information on this in chapter .

Signals to the Communication Modules

Description of the Signals to the Communication Modules

There are different signals for each communication module: Channel Live

The signal Channel Live displays the data flow. Therefore, the signal indicates that the communicationservice is transmitting and receiving data on the module.Consider that multiple services can run in parallel on one Ethernet module. The representation is definedin the standard IEC 61850, Edition 2.

Module readyThe signal Module ready indicates that the module has started and the protocol applications are started.You can reallocate this signal, for example, LED, log, or message. Then, you will recognize whether theIEC 61850 services are stared on an Ethernet module, for example GOOSE. and are working correctly.

iiNOTE

Starting the module can take some time.

HealthThe signal Health indicates the state of the module. The following 3 states can occur in this case: Okay

Module OK indicates, that the module is working.

WarningThis state is not used.

AlarmThe state Alarm is set when there is a failure of the module.

Each protocol application has a Health node. If a protocol has problems at startup, for example, missingparameters, no mapping, no hardware support, the status is set to Alarm. An alarm in a protocol causes analarm of the module.

Setting Parameters in DIGSI 53.3 Signals to the Communication Modules


Select Mapping

With the selection of the protocol on a channel, the mapping for the DNP3 protocol is also determined. Theroutings defined in the mapping are displayed in the Communication Data Mapping Editor for each channel.Standard mapping contains prioritized indications, measured values, and commands.A standard mapping is provided for the DNP3 protocol. The standard mapping contains the routings, whichare specified by the DNP3 protocol.Routings in the communication matrix are also possible without selecting an existing mapping file.

parameters

Removing existing signals (removing the marker) Changing the protocol routings (group and index)All information which is not dimmed in the Communication Mapping working area can be routed to theprotocol. The routing of some typical data types is explained in more detail below:

Indications

The indications are routed by highlighting the object in the Transmit column.Notifications are information that is sent to a DNP3 master. After this, the parameters required for the DNP3protocol must be entered.The following parameters are necessary: Object group

Object group 1 is preset for messages.

Index ClassYou can route the following IEC 61850 data types to indications (binary inputs): SPS (Single point status) DPS (Double point status) ACD (Directional protection activation information) ACT (Protection activation information)You can map the two data types ACD and ACT to SPS indications only via conversions. Conversions areused to map individual information contained in the data types.

The mapping of the commands occurs like the mapping of messages. Here, object group 12 is preset.

iiNOTE

For commands, the DNP3 protocol allows both direct operate and a select before switching. The type ofswitching is configured by the switching object; this means the protocol takes over the mode that is para-meterized in the switching object.

You can route the following IEC 61850 data types to commands (binary output): SPC (Single-Point Control) DPC (Double-Point Control)If a command status signal should be mapped or if it is preset through the control model, the status signalfrom the command will be parameterized in the same line under the Transmit column.

Supported Control Models

The SIPROTEC 5 device supports the control models (according to IEC 61850): Direct with normal security SBO (Select before operate) with normal security Direct with enhanced security SBO with enhanced security

Measured Values

The measured values are routed by highlighting the object in the Transmit column. After this, you must enterthe parameters required for the protocol.The primary values are carried over from the Master.The following parameters are necessary: Group Index Scaling

3.5.4



Object Class

[scmmednp-251110-01.tif, 1, en_US]

Figure 3-9 Mapping of Measured Values

Scaling Measured Values

The measured values between the SIPROTEC 5 device and the DNP3 master are transferred as integervalues in 16-bit or 32-bit format. 16 bits correspond with a range from 0 to 65 535; 32 bits correspond with arange from 0 to 4 294 967 295.You can find more detailed information on this in chapter 3.4 Select Mapping.The measured values are available in the SIPROTEC 5 device in floating-point format, related to the parame-terized rated variables of the primary system in percentage.

Converting Measured Values

Before the transfer of a measured value through DNP3, the measured values must be converted in theSIPROTEC 5 device. The measured values are scaled.The scaling of a measured value determines the form of transmission. These forms of transmission are: Value type Scaling factor

Scaling Factor

The measured value is multiplied in the SIPROTEC 5 device by the scaling factor. The measured values arethen changed into integer measured values (for DNP3) in the floating-point procedure.Through multiplication with a multiple of 10, decimal points can also be transferred into integer measuredvalues.

Calculation Formula for Integer Measured Values

The following conditions must be met for the calculation: The floating-point number (measured valueFloat) is available in the corresponding value type (primary or

secondary value).

The floating-point number (measured valueFloat) is available as a percent value.The integer measured value (measured valueInteger) for the transmission through DNP3 is calculatedaccording to the following formula:



[fomwintr-230310-01.tif, 1, en_US]

Setting the Measured-Value Threshold

In the measured-value processing via DNP3, there are measured-value thresholds you can set. The meas-ured-value threshold for the individual measured values is not set in the communication matrix but centrally inthe routing matrix. The following measured-value thresholds are preset:

Measured-Value Threshold Setting Valuedb5 for values from type frequencies:(neutral zone for values of the type Frequencies)

0,1 %

db for values from type voltages:(neutral zone for values of the type Voltages)

2 %

db for values from type currents:(neutral zone for values of the type Currents)

10 %

db for values from type power:(neutral zone for values of the type Power)

10 %

db for values from type all others:(neutral zone for values of the type all others)

10 %

dbAng for values from all type angles:(neutral zone dbAng for values of all type angles)

1 %

This setting value applies to the currently measured value. If, for instance, the measured value is 110 kV andthe preset value is 2 %, then the measured value will be transmitted in the event that the measured valueschanges by 2.2 kV.

Counter Values

All of the IEC 61850 objects of type BCR (Binary Counter Reading) in the SIPROTEC 5 device can be routedto counter values (object type 20). The routing takes place by marking the object in the Transmit column.

An Example Calculation for a Measured Performance Value

The following parameters are included in the parameter set: Rated operating voltage of the primary system = 12.00 kV Rated operating current of the primary system = 100 AThe measured performance value is calculated based on the following formula:

[foleismw-121109-01.tif, 1, en_US]

In the SIPROTEC 5 device, this measured performance value is stated from 0.00 MW to 9.99 MW, that iswith 2 relevant decimal points.Siemens recommends a scaling factor of 100 for the transmission as an integer measured value throughDNP3. With this, a value from 0 to 999 is transferred to the master.If the scaling factor is less than 100, then important information about the decimal points is lost during thetransmission. A scaling factor larger than 100 does not create any precise information. The accuracy is onlysimulated, but really non-existent. Thus, with a scaling factor of 100 there is an interpretation of the integermeasured value (measured valueInteger) through DNP3 with: 32 768. This corresponds with a value of 327.68 MW.

Number Representation Depending on the Parameterization

If you determine the scaling of a measured value, then you first set the number format and the unit. Thenumber format contains the number of relevant decimal places.

Percent Values

For percent values, Siemens recommends a scaling factor of 100. This results in an interpretation of theinteger measured value (measured valueInteger) through DNP3 with a measured value from 32 767. Thiscorresponds with a percentage value of 327.67%.

3.5.6

3.5.7



Secondary Values

If, for example, the values from the transducer inputs are specified in mA, then the transmission of a meas-ured value as a secondary value makes sense.The number of significant decimal points depends on the system and transducer data.

Primary Values

The position of the decimal point and the respective unit are determined for primary values based on theparameterized rated variables of the primary system.

Time Synchronization

Parameters for 2 main clocks can be set in a SIPROTEC 5 device. If one of the time sources in the device isset to DNP3, then the time synchronization runs through a DNP3 master. The time sources are set in DIGSI 5or on the device.Make the time synchronization settings in DIGSI 5 in the Time Settings Editor in the Parameters category.

Adjust the time sources in the Time Source 1 and Time Source 2 fields. If the DNP3 protocol is parameterizedfor a number of channels in the device, you can select this protocol for both sources.

Figure 3-21 Setting the Time Sources

If the time source in the device is set to DNP3, then the time synchronization can run through a DNP3 master.The time source is set in DIGSI 5 or on the device.In the DNP3 protocol, you have the possibility to execute time synchronization with local time or with UTC.The selection occurs in DIGSI 5 with the parameters designated for this. The time zones for the time synchro-nization parameterization and in the DNP3 protocol have to be identical if set to local.The SIPROTEC 5 device monitors the continuous reception of the time synchronization telegram. After expiryof the set time in Error display after: a time synchronization error message is generated. The faulty time in thedevice is also displayed. This time fault remains until a new time synchronization telegram is received.

iiNOTE

During parameterization, the time in Time synchronization required must be greater than the synchroniza-tion interval of the DNP3 master. Siemens recommends a synchronization interval of 1 min. However, themaster can also send the telegram every 5 min or 10 min. When setting the interval to 1 min, the time inthe device is set to invalid if no synchronization telegram is received in 2 min. In the meantime, the devicesets the clock via the internal quartz-crystal oscillator.

Overview

SIPROTEC devices can be ordered with factory-installed communication modules. The communicationmodules can also be installed and replaced in the SIPROTEC devices afterwards. You do not have to openthe device for this.

iiNOTE

The communication modules available for reordering are not preconfigured. Use DIGSI 5 to carry out thefunctional adjustment to the required protocol application.

The communication modules can be installed in the base module or the 1/3 module and in the expansionmodule with the plug-in module assembly CB202. A maximum of 2 communication modules each can beinstalled. You can use only one CB202 in the device.The plug-in module assembly CB202 is a module with an integrated power supply.The CB202 plug-in module assembly PCB communicates with the base module via a special connectingcable. This connecting cable (CAT 5 FTP patch cable) is always included in the scope of delivery of theCB202 assembly or the devices containing the CB202 assembly and need not be ordered separately.Ensure that you route the communication lines separately from network circuits.

The following communication modules can be used for SIPROTEC 5: Serial modules

Application: Communication to the substation automation technology via substation-control protocolsProtection interface (only optical serial modules) for interfacing to external communication converters forshort direct connections.2 different communication protocols or 2 different applications can be operated on serial modules with 2connections. The IEC 60870-5-103 protocol for the substation automation technology as well as aprotection interface, for example, can be operated on a serial optical module for close range with2 connections.Assign the protocol application to the corresponding channel of the communication module with DIGSI 5.



Ethernet ModulesApplication: Ethernet-based communication to the substation automation technology via substation-control protocols (for example, IEC 61850 and DNP3) Secure communication to DIGSI 5

Communication between the devices (IEC 61850-GOOSE)

Synchrophasor protocol

The modules can be operated with or without an integrated switch.

Long-distance modulesApplication: Direct protection interface communication over long distances using multimode or single-mode optical fibers.

The designation of the modules corresponds to the following scheme, which is typically explained with themodule USART-AB-1EL. The module designation consists of 3 blocks.

1st block Type of moduleUSART = Serial module for short or long distanceETH = Ethernet module

2nd block Unique code for the module in the product code of the deviceThe code consists of 2 letters.

3rd block Number and physical design of the connections1 = 1 connection (1 channel)2 = 2 connections (2 channels)EL = Electrical connectionFO = Fiber-optic connectionLDFO = Long-distance transmission via fiber-optic cables
