7XV5101RS232-FO Connector Modules

Connector modules 7XV5101

Optical connection of protection relayswith an electrical (non-isolated) RS232interface, e.g. to a star coupler, for central-ized control is made possible with thefiber-optic RS232 connector modules.

Thus, further devices such as PCs or note-books, modems or serial data switches canbe effectively protected against electromag-netic interference. An appropriate connec-tor module is available for each of theabove-mentioned applications. Thesefiber-optic RS232 connector modules arehoused in a SUB-D plug casing and can bedirectly plugged into the respective inter-faces of the pertaining devices. No furthersettings are required. In its normal posi-tion, the optical interface is set to steadylight OFF. Data transmission is fully du-plex and transparent. The optical interfacewith FSMA connectors has an operationalwavelength of 820 nm and can reach dis-tances of up to 1500 m with 62.5/125 µmmulti-mode FO cables.

The various designs differ from each otherin the number of pins (9 or 25 poles), inthe design of the connector (male or fe-male) and in their mode of auxiliary volt-age supply (pin 9 from device or plug-inpower supply unit (PSU). Further infor-mation on application and design can beobtained from the selection and orderingdata.

Elbow plug 7XV5101-8

The 25-pin elbow plug allows an opticalconnection to be established between theprotection relays and the star coupler oractive mini star- coupler via the operatorinterface and fiber-optic connector mod-ules. The front cover of the relay remainsclosed.

For the fiber-optic cables, a recess shouldbe worked into the front panel frame sothat the fiber-optic connector modules7XV5101-0A can be conveniently placedunderneath the front cover. The auxiliaryvoltage is supplied from the protectionrelay at its serial interface from pin 9.

The elbow plug is available in two differentdesigns matching the different types ofprotection relays.

• Metal-plated, shielded connector hous-ings with reduced mounting depth andstrain relief.

• Bus termination with terminating con-nectors and integrated resistor.

• Connection of the SIPROTEC 4 pro-tection devices with redundantIEC 60870-5-103 interface via theY-adapter cable and RJ45 connector.

• Connection of the SIPROTEC 4 protec-tion devices with RS485 interface andSUB-D connector directly, or via aY-adapter cable.

• Adapter/cable for compact protectiondevices with RS485 interface onscrew-type terminals, e.g. 7SJ600,7SD600, 7RW600 etc.

• Connection to various RS485 convert-ers, e.g. 7XV5650/51.

• Combination of both bus systems ispossible.

• Max. length of the bus within a com-mon grounding system may be up to1000 m.

Please note that this system must not be usedfor PROFIBUS-FMS or PROFIBUS-DP.These have their own bus system with com-ponents suitable for use with PROFIBUS.

7XV5103RS485 Bus Systems up to 115 kbit/s (not suitable for PROFIBUS)

The RS485 bus is a low-cost half-duplexcommunication bus, which, due to its rela-tively high interference immunity, is notonly used for monitoring and control inindustrial systems, but is now increasinglyused for SCADA and protection applica-tions by utilities in substations. Protocols,such as DIGSI, IEC 60870-5-103, DNP 3and MODBUS up to 115 kbit/s, are usedbetween a station master and up to 31 slavedevices on shielded twisted-pair (STP) ca-ble. In ideal conditions, the length of thebus may be up to 1000 m. This requirescorrect configuration of the bus, use ofsuitable cables, and connector connectors,as well as correct termination of the bus.Devices with different termination meth-ods require special adaptors to achieve thehighest possible interference immunity.The RS485 bus systems 7XV5103 are opti-mized in this respect for our control andprotection product range.

With the ordering code 7XV5103, twodifferent RS485 bus systems are available.

When combining the required compo-nents for a RS485 bus, the correspondingapplication examples contained in thisdocument can be of assistance.

The bus system with 9-pin SUB-D connec-tors has long been applied in systems withSIPROTEC protection devices, 7XV5 con-verters, and master units. Connection tothe individual devices is achieved directlywith a special Y-cable or with a corres-ponding adapter cable to devices withdifferent termination methods. The busterminates in a 9-pin SUB-D bus terminat-ing connector with an integrated 220-Ωresistor.

On some SIPROTEC devices, the serialsignals are routed to RJ45 female connec-tors on the communication module, as isthe case, for example, with the redundantIEC 60870-5-103 module. There the bus isbased on double-shielded CAT 5 patch ca-bles. Connection of the individual devicesto the two redundant buses is achieved viatwo special Y-adapter cables each. Thebuses each terminate with a RJ45 bus ter-minating connector with a 120-Ω resistor.

A combination of the two bus systemsand the different device interfaces or acombination of the two systems is alsopossible using the Y-adapter cable7XV5103-2BA00.

Notes on configuring the RS485 bus system

The housings of all devices connected tothe bus must be solidly grounded to acommon ground to avoid dangerousground currents flowing via the cableshields.

Larger distances, especially into otherbuildings with separate grounding systemshould preferably be covered via converters(e.g. 7XV5650/51) using FO links.

The RS485 bus must be linear, i.e. tee-offsfrom the bus (e.g. a terminal strip) to theconnected bus devices must not be used.This would form a star configuration,which has negative influence on the func-tionality.

The bus must be terminated at the first de-vice (usually the master) and at the last de-vice with a bus terminating resistor toavoid interference due to reflection. Nofurther terminating resistors must be con-nected between these terminals.

As all of the devices, maximum 32 (includ-ing the master) are listening in on theRS485 bus, all the devices on the bus mustbe set to the same baud rate and the samedata format.

The slaves must all have different deviceaddresses.

Within the system, only one master may beactive at any one time and only one slavemay respond.

The bus system with 9-pin SUB-D connectors

The bus system with 9-pin SUB-D bus ter-minating connectors has long been usedwith SIPROTEC protection devices, theconverters 7XV5 and Siemens masterunits. Connection of individual devices todevices with various connection modes isachieved directly via specialized Y cables,or via suitable adapter cables. The bus ter-minates at a 9-pin SUB-D bus terminatingconnector with an integrated 220-Ω resis-tor.

• Connection to the FO-RS485 converter7XV5650 or the bus system with SUB-Dconnector via Y-adapter

Notes on configuring the RS485 bus system(application examples 2 and 3, see page 15/9)

The housings of all devices connected to thebus must be solidly grounded to a commonground to avoid dangerous ground currentsflowing via the cable shields.

Larger distances, especially into otherbuildings with separate grounding systemshould preferably be covered via converters(e.g. 7XV5650/51) using FO cables.

The RS485 bus must be linear, i.e. tee-offsfrom the bus (e.g. a terminal strip) to theconnected bus devices must not be used.This would form a star configuration,which has negative influence on thefunctionality.

Only CAT 5 double-shielded patch cables(e.g. 7KE6000) must be used as the bus ca-bles. The maximum bus length must notexceed 800 m.

The bus must be terminated at the first de-vice (usually the master) and at the last de-vice with a bus terminating resistor toavoid interference due to reflection. Nofurther terminating resistors must be con-nected between these terminals.

Application

Application example 2: Connection ofSIPROTEC 4 to a (redundant) control system

The RS485 bus cable system with patchcables (CAT 5) was developed as a low-cost alternative to the previous systems7XV5103 with SUB-D connectors. The ad-vantages are the widespread use of patchcables throughout the world and the com-pact dimensions of the RJ45 connector.This allows a redundant IEC 60870-5-103interface with a single interface modulewithin a SIPROTEC 4 device.

Two different Y-adapters permit imple-mentation of a RS485 bus with patch ca-bles and connection of devices havingRS485 interfaces and different designs ofinterface connector. Both Y-adapters havetwo RJ45 female connectors in parallel tofacilitate the implementation of the buses.The approx. 20 cm long connection cableto the device either has a RJ45 or SUB-Dconnector.

Devices with SUB-D connector (e.g. Mas-ter RTU, 7XV5650/51, SIPROTEC 4 de-vices with SUB-D) are connected using theY-adapter 7XV5103-2BA00.

Devices with RJ45 connector such asSIPROTEC 4 with redundantIEC 60870-5-103 interface are connectedwith the Y-adapter 7XV5103-2CA00. Forthe redundant bus system 2 Y-adapters arerequired per SIPROTEC 4 device.

After the final device the bus is terminatedwith a bus terminating connector7XV5103-5BA00. For the redundant bussystem, a bus terminating resistor is re-quired for each bus.

Application example 3: Central operationof SIPROTEC 4 units with DIGSI 4

The RS485-bus cable system with patch ca-bles (CAT 5) was developed as a low-costalternative to the previous systems7XV5103 with SUB-D connectors. The ad-vantages are the widespread use of patchcables throughout the world and the com-pact dimensions of the RJ45 connector.

The Y-adapter 7XV5103-2BA00 allows forthe implementation of a RS485 bus withpatch cables and the connection of variousSIPROTEC devices having RS485 interfaces.The Y-adapters have two RJ45 female con-nectors in parallel to facilitate the imple-mentation of the buses. The approx.20 cm long connection cable to the devicehas a RJ45 with suitable pin allocation.

Devices with an RS485 interface andSUB-D connector (7XV5650/51,SIPROTEC 4 devices) with SUB-D areconnected using the Y-adapter7XV5103-2BA00.

Devices with an RS485 interface on screw-type connectors require an additionaladapter for 9-pin SUB-D to single core,e.g. 7XV5103-2AA00 or 7XV5103-3AA00.

After the last device, the bus is terminatedwith a bus terminating connector7XV5103-5BA00.

7XV5104Bus Cable for Time Synchronization

The evaluation of fault records, operationalalarms and fault signals calls for millisec-ond-accurate determination of the abso-lute time. The SIPROTEC 4 units have aninternal clock on a quartz basis, which de-viates from the normal time after a while.Radio clocks are therefore used for precisesynchronization; they set the clocks in thedevices via time signals or protocols suchas DCF77 or IRIG-B. All the devices areconnected in parallel with an electrical bus,so that all of them receive the time infor-mation at the same time at Port A. Bymeans of the prefabricated bus cables andadapters 7XV5104 the SIPROTEC 4 unitscan be connected via their IRIG-B interfacedirectly to the sync.-transceiver 7XV5654.The maximum length of the electrical buswhen prefabricated cables are used is20 m. Relevant applications are describedin the manual for the sync.-transceiver7XV5654.

Notes on the IRIG-B bus

In this system solution only the 24 V DCtime synchronization inputs of theSIPROTEC 4 units are used (see below).7XV5105 cables are available for synchro-nizing the differential protection relayswith an additional seconds pulse.

The housings of all bus users must be prop-erly mutually earthed, as otherwise danger-ous earth potential currents can flow via thebus cable shield.

Typical applications

The 9-pin male connector of the Y-bus ca-ble S1 always comes from the direction ofthe radio clock or sync.-transceiver andprovides via the 1, 3, 5 or 10 m cable andthe 9-pin male connector the connectionto the first and subsequent bus devices. Atconnector S2 a 9-pin female connector B3is provided (on a 20 m long cable) to ex-tend the bus. If more than six SIPROTEC 4units are to be connected to thesync.-transceiver 7XV5654, the adapter7XV5104-3AA00 splits the connection X1of the sync.-transceiver into two buses fora maximum of 6 units each. (For typicalapplications see 7XV5654 manual).

7XV5105Bus Cable for Time Synchronization (for 7SD5 Relays)

The evaluation of fault records, operationalalarms and fault signals calls for a millisec-ond-accurate absolute time stamp. The dif-ferential protection relays have an internalclock on a quartz basis, by means of whichthe protection is normally synchronized.In special applications, GPS radio clocksare used to synchronize the 7SD5 differen-tial protection relays with the absolutetime. These clocks send a time telegramtogether with a microsecond-accurate sec-onds pulse, so that the transmission timein both the sending and the receiving di-rection can be precisely measured. All thedevices in each system are connected inparallel via an electrical bus, so that alldevices receive the time information andthe seconds pulse at the same time. Bymeans of the prefabricated bus cables7XV5105, the 7SD5 relays can be con-nected via their IRIG-B interface (Port A)directly to the sync.-transceiver 7XV5654.The maximum length of the electrical buswhen the prefabricated cables are used is20 m. Relevant applications are describedin the manual for the sync.-transceiver7XV5654.

Notes on the IRIG-B bus

In this system solution only the 24 V DCtime synchronization inputs (Port A) ofthe SIPROTEC 4 protection relays areused. 2-core 7XV5104 cables are availablefor time synchronization of the SIPROTEC 4protection relays without additional sec-onds pulse.

The housings of all bus users must be prop-erly mutually earthed, as otherwise danger-ous earth potential currents can flow via thebus cable shield.


The 9-pin male connector of the Y-bus ca-ble S1 always comes from the direction ofthe radio clock or sync.-transceiver andprovides via the 1, 3, 5 or 10 m cable andthe 9-pin male connector the connectionto the first and subsequent bus devices. Atconnector S2 a 9-pin female connector B3is provided (on a 20 m long cable) to ex-tend the bus. If more than six SIPROTEC 4units are to be connected to the radioclock, up to 4 sync.-transceivers 7XV5654can be connected, each with 6 protectionrelays. (For typical applications see the7XV5654 manual).

7XV5300Star Coupler

With this fiber-optic star coupler, the mes-sages of the relay operating software DIGSIor IEC 60870-5-103 protocol are distrib-uted to all relays via a maximum of30 fiber-optic interfaces. The transmittingFO interface (FO port) of the star coupler’sexpansion unit is connected to the relay’sreceiving FO interface. Every message con-tains an address so that only the corre-sponding relay will answer. This relay nowsends the answer back to the operator PCvia the expansion module’s receiving FOinterface and the main module’s transmit-ting FO interface.

Function overview

• Up to 30 SIPROTEC relays can be re-motely operated via fiber-optic cables

• The smallest assembly unit consistsof a main module including a powersupply unit (PSU) and an expansionmodule with 3 FO interfaces

• Up to 9 additional expansion modulescan be installed later, making commu-nication via 30 FO interfaces possible

• The star-coupler is cascadable

• All fiber-optic interfaces (full duplex)have FSMA connectors and thesteady-light indication can be set to ONor OFF individually (manufacturer’spresetting: “OFF”)

• An RS232 interface with a 9-pin SUB-Dminiature connector allows the relaysalso to be operated locally

• The fiber-optic interface on the mainmodule is inactive when the RS232 in-terface is being used

• Data is transmitted transparently, i.e.independent of any protocol

• The wavelength of all ports is 850 nm

• The max. distance between star couplerand relay is approx. 1.5 km

• The power supply covers the followingvoltage ranges without switching:48 - 250 V DC and 110 - 220 V AC. Thepower supply has been designed for themaximum configuration

• Every module has 3 LEDs: one for theoperating voltage (green), one for theflow of data (yellow) and one in case ofdisturbance (red)

7XV5450Mini Star-Coupler

The mini star-coupler multiplies an opti-cal signal received at an input for up tofour outputs. A signal received at one ofthe outputs is transmitted via the inputinterface to a central unit or to an up-stream mini star-coupler or converter. Asthe mini star-coupler does not transmit se-lectively to individual outputs, the proto-cols used for data transmission mustoperate with unique DTE addresses, so allunits “hear” the central interrogation, butonly the addressed unit answers to therequest (e.g. IEC 60870-5-103 or DIGSI).

Data are transmitted in transparent full-duplex mode. An RS232 interface is pro-vided for direct serial communication withDTEs at each mini star-coupler. As long asthis interface is in use, the optical input in-terface to the central unit is blocked.

Cascading mini star-couplers replace the7XV5300 star coupler.

7XV5461Two-Channel Serial Optical Repeater (for mono-mode FO cables)

The optical repeater transmits serial opticalsignals over long distances via mono-modeFO cables. It converts serial optical 820 nmsignals at Port 1 and Port 2 in the range of300 bit/s to 4.096 Mbit/s. Both synchro-nous and asynchronous signals can be con-nected. Two independent, serial 820 nminputs with ST connectors are available,which are multiplexed to Port 3. Two de-vices with an optical 820 nm interface, forexample the 7SD5 / 7SD6 line differentialprotection relay or the RS232/820 nm7XV5652 converter, can be connected toPorts 1 and 2 via multi-mode FO cables fordistances of up to 1.5 km. Signal transmis-sion at Port 3 is achieved via the LC-Du-plex connector at wavelengths of 1300 nm/1550 nm for connection of a mono-modeFO cable. For Port 3 there are three op-tions for max. 25 km (1300 nm) / 60 km(1300 nm) / 100 km (1550 nm) and 170 km(1550 nm) optical fiber lengths. The device can be connected to all battery voltages and AC supply sources. Loops can be activated for Ports 1 / 2 for commissioning purposes, so that the input signalscan be mirrored at the port in question.

The protection relays (for example 7SD5 /7SD6 differential protection or 7SA52 /7SA6 distance protection) exchange infor-mation via Port 1. Interference-free dataexchange is performed via mono-modeFO cable up to a distance of 100 km. Pro-tection remote control with DIGSI is con-nected to Port 2 of the repeater via the7XV5450 mini star-coupler. This portprovides the serial connection to the othersubstation with a PC where DIGSI is in-stalled. The protection relays on the re-mote substation can be scanned remotelyvia Port 2. The baud rate is optimally setto 57.6 kbit/s so that there is no differencefrom local operation. During commis-sioning and operation, data of the deviceon the other substation can be changedand read out. Alternatively, it is possibleto connect power system control or addi-tional protection data transmission toPort 2. This makes for optimum use ofthe long-distance optical fiber for two se-parate serial connections for transmittingdata between 300 bit/s and 4.096 Mbit/s.

7XV5662-0AA00 / 7XV5662-0AA01Communication Converter for X.21/RS422 and G.703.1

The communication converter for cou-pling to a communication network is a pe-ripheral device linked to the protectiondevice via fiber-optic cables, which enablesserial data exchange between two protec-tion relays. A digital communication net-work is used. The electrical interfaces inthe CC-XG for the access to the communi-cation device are selectable as X.21(64 kbit/s, 128 kbit/s, 256 kbit/s or512 kbit/s) or G.703.1 (64 kbit/s). At theopposite side, the data are converted bysecond communication converter so thatthey can be read by the second device. Thecommunication converters thus allow twoprotection devices to communicate syn-chronously and to exchange large data vol-umes over large distances. Typicalapplications are the serial protection inter-faces of differential protection and distanceprotection of the devices 7SD5, 7SD6,7SA52 and 7SA6, where 7XV5662-0AA00must be used.

Should asynchronous serial data of differen-tial protection 7SD51 or of the binary signaltransducer 7XV5653 be transmitted, thedevice 7XV5662-0AA01 must be used(asynchronous from 300 bit/s to 115.2 kbit/sdependent on the baudrate set for X.21 orG.703.1 interface). Interference-free con-nection to the protection device is achievedby means of a multi-mode fiber-opticcable, with ST connectors at the CC-XG.The maximum optical transmissiondistance is 1.5 km (0.93 mile).

Function overview

• Optical interface with ST connector forconnection to the protection unit

• Distance: 1.5 km with 62.5/125 µmmulti-mode FO cable between CC-XGand the protection unit / serial device

• Synchronous data exchange for 7SD52,7SD6, 7SA6 and 7SA52 protectionrelays (communications converterversion – 0AA00)

• Asynchronous data exchange for 7SD51protection relay, 7XV5653 or otherdevices with asynchronous interface(communication converter version –0AA01)

• Max. cable length between communica-tion device and communication con-verter: 100 m for X.21 /RS422

• Max. cable length between communica-tion device and communication con-verter: 300 m for G.703.1

7XV5662-0AC00/7XV5662-0AC01Communication Converter for Pilot Wires

The communication converter copper(CC-CO) is a peripheral device linked tothe protection device which enables serialdata exchange between two protectionrelays. It uses a single pair of copper wires(pilot wire) that may be part of a telecom-munications cable or of any other suitablesymmetrical communications cable (noPupin cable). At the opposite side, the dataare converted by a second communicationconverter so that they can be read by thesecond protection device. The communi-cation converters (master/slave) thus allowtwo protection devices to communicatesynchronously and to exchange large datavolumes over considerable distances. Typi-cal applications are the protection inter-faces of differential protection and distanceprotection of the devices 7SD5, 7SD6,7SA52 and 7SA6, where 7XV5662-0AC00must be used (synchronous connectionwith 128 kbit/s). Should asynchronous se-rial data of differential protection 7SD5 orof the binary signal transducer 7XV5653 betransmitted, the device 7XV5662-0AC01must be used (asynchronous from 300 bit/sto 38.2 kbit/s).

Function overview

• Optical interface with ST connector forconnection to the protection unit

Functions

The protection unit is opticallylinked to the CC-CO, which makesinterference-free data transfer be-tween the CC-CO and the protec-tion unit possible. The communi-cation converter is located close tothe pilot wire. It converts serialdata of the protection unit into afrequency-modulated signal. Thissignal is transmitted via one pair ofcopper wires of a pilot wire/com-munication line (bi-directional,full duplex operation).

The CC - CO can be used for twoapplications.One application is the synchronousserial data exchange (converterversion – 0AA00) betweenSIPROTEC 4 differential relays(7SD52, 7SD6) and/or the serialteleprotection between distance re-lays (7SA6 and 7SA52). The relayshave to be equipped with an opti-cal 820 nm plug-in module “FO5”.

Another application is the trans-mission of asynchronous serialdata via pilot wires to the line dif-ferential protection relay 7SD51 orthe binary signal transmitter7XV5653. Other serial devices mayalso be used.

If the maximum distance betweenthe protection units is longer thanspanned by two CC-CO, theconverters can be cascaded (seeFig. 15/45). A power supply be-tween the two master units is re-quired. If the isolation level ishigher than 5 kV (provided by thepilot wire inputs of the units), ex-ternal isolation transformers (bar-rier transformers) can be used onboth sides. These transformersoffer 20 kV isolation voltage andthus help to avoid hazardous highvoltages at the inputs of theCC-CO, which might be inducedby a short-circuit from a parallelpower line or cable.

By means of jumpers, one unit isdefined as “master” and the otherunit as “slave”. In a “training” dur-ing commissioning, the electricalcharacteristics of the pilot wire aremeasured by pressing a pushbutton,and the CC-COs are tuned to thesecharacteristics.

The measured characteristics areused as parameters that will be ad-hered to for optimal data transfer.Digital data transfer makes a lowinsulation level of the pilot wirepossible, because no high voltagesare produced on the pilot wireduring short-circuit conditions.

Data transfer between the protec-tion units is effected on the basis ofa point-to-point connection, fur-thermore it is a synchronous,bit-transparent transmission. Dueto the telegram-backed data ex-change, mal-operation is ruled out.

Itconverts synchronous or asynchronous se-rial 820 nm optical input signals at inputsFO1 and FO2 to a network interface andagain returns these signals at the remoteterminal via the latter's interfaces. FO1 andFO2 may be configured independently foreither synchronous or asynchronous oper-ation, but must be set to the same operat-ing mode at both ends. In synchronousmode, the interface should only be usedfor exchanging the protection data of the7SD5/7SD6 differential protection or7SA52/7SA6 distance protection and ispreconfigured for 512 kbit/s. In asynchro-nous mode, the interface can be used forconnection of devices with baud rates be-tween 1.2 to 115.2 kbit/s. A further asyn-chronous electrical RS232 interface isprovided for max. 115.2 kbit/s. It providesfor the connection of a serial PC interfacewith DIGSI and thereby the operations in-terface to SIPROTEC devices at the remoteend. The G703.6 network interface is pro-vided in the form of 4-way screw terminalsand can be configured as a 2-Mbit/s inter-face with European E1 format or as a1.544-Mbit/s interface in the American T1format. All settings of the device are madewith jumpers, so that no special PC soft-ware is required.

Technical data

Two protection devices e.g. 7SD52/7SD610 differential protection or7SA52/7SA6 distance protection, exchangeprotection data via FO1. Interference-freedata exchange is performed via the com-munication network, the devices beingconnected synchronously with 512 kbit/s(connection 1; see Fig. 15/47). Protectionremote control with DIGSI is connected toFO2 of the converter via a 7XV5450 ministar-coupler. This port provides theserial connection to the other substationwith a PC on which DIGSI is installed. Inthis way, the remote protection devices canbe remotely interrogated via FO2 (connec-tion 2). The baud rate is optimally setto 57.6 kbit/s for SIPROTEC 4 devices, sothat there is no difference from local oper-ation. The data of the devices on the othersubstation can be changed and read outduring commissioning and operation.Alternatively, it is possible to connect asubstation control system or additionalprotection data transmission to FO2.This makes for optimum use of the1.544/2 Mbit/s transmission channel fortwo separate serial connections. In addi-tion, an asynchronous serial connection isavailable via the RS232 interface, whichcan be used to temporarily operate devicesof the other substation with DIGSI.

7XV5662-�AD10Temperature Monitoring Box

The temperature monitoring box (alsocalled RTD-unit(resistance temperaturedetector) or thermo-box) can be used to-gether with the 7UT6, 7UM62 and 7SJ6 re-lays for thermal monitoring of machinesand transformers. It is connected via its se-rial RS485 interface to the RS485 interfaceof the SIPROTEC 4 units. External opto-electrical converters (7XV5650 / 7XV5651),however, allow the RTD unit to be con-nected to the optical 820 nm interface ofthe protection relay (Port C or Port D).Measurement of 6 temperature values is ef-fected by Pt100 (recommended), Ni100 orNi200 sensors and transmitted by tele-grams to the SIPROTEC relay. The relaydisplays the measured values, monitorsthem and generates alarms when previ-ously parameterized limiting values are ex-ceeded. For 7UT6 with its extensivetransformer monitoring functions, specialfunctions like hot-spot calculation areavailable. Wiring to the sensors and wirebreakage are monitored as well. Two boxeswith a maximum of 12 sensors (this corre-sponds to 12 measuring locations) can beconnected to one SIPROTEC relay.

Function overview

• Measurement and display of 6 tempera-tures with Pt100, Ni100 or Ni120 sen-sors per box. With two boxes: a total of12 measurements.

• Connection of up to 2 boxes via theRS485 interface of the relay. Opticalconnection can be established withadditional converters (7XV5650 /7XV5651)

• 2- or 3-wire connection of thermal sen-sors is supported (3-wire connectionrecommended)

• Monitoring of each sensor wiring andalarm in case of wire breakage. Alarm isindicated in the box itself and in the re-lay monitoring function.

• Measuring range of temperature forPt100: -100 °C to +800 °C

A maximum of two RTD units can be con-nected to a protection relay. These unitsoffer up to 12 RTD inputs, which can bemonitored by the RTD function in the re-lay or supervised by a user-defined logic inthe relay, where user-defined alarms can begenerated. The connection (up to 1000 m)between the RTD unit and the relay can bemade by an RS 485-electrical bus. For dis-tributed RTD units or fully interference-free connections, FO connections are rec-ommended. Fig. 15/50 illustrates the appli-cation with FO cables and 7XV5651converters. If only one RTD unit is con-nected to the relay it is sufficient to haveone FO connection from the 7XV565xconverter to the relay.

7XV5664 /7XV5654GPS/DCF77 Time Synchronization System

The 7XV5664 GPS/DCF77 time signal re-ceiver (TSR) is part of the time synchroni-zation system for all SIPROTEC 4 units. Itis equipped with an antenna and a 25-mscreened cable. The other devices of thetime synchronization system are the7XV5450 mini star-coupler (optional) andthe 7XV5654-0BA00 time synchronizationunit (sync.-transceiver).A user-friendly software package for PC(included in the scope of delivery) facili-tates configuration of the receiver via anRS232 interface.

The optical outputs provide interference-free transmission of the time signals to therelays. Close to the relays, the sync.-trans-ceiver 7XV5654 converts these optical sig-nals to electrical signals. These signals areinput signals for Port A of SIPROTEC 4units or for binary inputs, which can alsobe used for time synchronization.

Function overview

• An optical output with ST connector isprovided for potential and interference-free direct transmission of DCF77 orIRIG-B time synchronization telegramsto the SIPROTEC 4 units. There theyare converted to an electrical signal by a7XV5654-0BA00 time synchronizationunit and injected via the time synchro-nization interface of the SIPROTEC 4units (Port A) (see Fig. 15/52).

• On a second optical output, a high-precision minute or second pulse can beissued with microsecond accuracy.

• With this minute pulse, the SIPROTEC 4unit internal clock can be synchronizedvia a binary input. The opto-electricalconverter 7XV5654-0BA00 supportsthis process.

• A special application of the pulse-per-second function is the highly accuratesynchronization of 7SD52 differentialprotection unit versions that feature theGPS synchronization function. This fa-cilitates the exact detection of the trans-fer time of telegrams between the unitsin both the transmit (send) and thereceive direction.

• The receiver requires 24 V DC powersupply. Other auxiliary voltages may beconverted to 24 V DC by the DC/DCconverter 7XV5810-0BA00.

7XV5655-0BB00Ethernet Modem

A control PC and protection relays can ex-change serial data via an Ethernet networkusing two Ethernet modems 7XV5655.Connection to the Ethernet modem is ineach case made via the asynchronous serialinterface of the terminal devices. In themodem the serial data is packed into thesecure IP protocol as information data,and is transferred between the modemsusing the Ethernet connection. Conformitywith the standard and gap-free transmis-sion of serial DIGSI orIEC 60870-5-103/101 telegrams (frames)via the network is ensured by the modemwhich receives the serial telegram commu-nication and packs the serial IEC telegramsinto blocks for communication via theEthernet. Data is transmitted in full duplexmode, the serial handshake is not sup-ported. Connection is set up between theIP address of the dialing modem in theoffice and the IP address of the answeringmodem in the substation and is configuredprior to dial up with DIGSI by means ofAT commands via the RS232 interface.

The substation modem may be configuredto have password protection, and providesthe additional security feature, permittingaccess only from defined IP addresses, e.g.only that of the office modem. The modemis accessed with DIGSI Remote like a nor-mal telephone modem with the exceptionthat instead of telephone numbers, IP ad-dresses are assigned by the network admin-istrator for each modem.

Application

Using the office computer and DIGSI 4,both substations 1 and 2 may be dialed upvia the Ethernet modems. An IP point-to-point data connection is established be-tween the office and correspondingsubstation modem when dialed up via thenetwork. This is maintained until the officemodem terminates the connection. The se-rial data exchange takes place via this dataconnection whereby the modem convertsthe data from serial to Ethernet with fullduplex mode. Between the office modemand the office PC the highest data rate e.g.57.6 kbit/s for SIPROTEC 4 devices is al-ways used. The serial data rate of the sub-station modem is adapted to the data raterequired by the protection relays e.g. sub-station modem 1 with 57.6 kbit/s forSIPROTEC 4 and substation modem 2with 9.6 kbit/s for SIPROTEC 3 devices.These settings are only pre-set once in themodem.

The Ethernet modems are integrated simi-larly to telephone modems in DIGSI 4.Instead of the telephone number, thepre-set IP address assigned to the modemis selected. If later an Ethernet connectionis available in the substation, the existingmodem can be replaced by an Ethernetmodem. The entire serial bus structure andcabling may remain unchanged.

7XV5655-0BA00Ethernet Serial Hub for Substations

By means of the serial hub and the associ-ated configuration software it is possible toestablish serial communication via anEthernet network between a PC or note-book running DIGSI 4 and SIPROTECprotection relays. The configuration soft-ware installs virtual serial interfaces (Comports) on the PC. Each COM port is allo-cated to a serial hub within the network bymeans of its IP address. This must be set inthe serial hub. The PC is connected to thenetwork via Ethernet interface. The pro-tection relays are connected via anRS232/RS485 or FO interface to the serialhub. Connection with DIGSI is achievedvia the virtual COM port on the PC andthe IP address of the serial hub in the sub-station. The serial data is packed as userdata into a secure IP protocol in the PCand transferred via the Ethernet connec-tion to the serial hub. The requirementsregarding standard compliant gap-freetransmission of serial DIGSI orIEC 60870-5-103/101 telegrams (frames)via the network is complied with by thecommunication driver on the PC and theserial hub which monitor the serial tele-gram communication. The serial IEC tele-grams are transferred in blocks across theEthernet. Data communication is fullduplex. Control signals of the serial inter-faces are not used.

From the office PC running DIGSI 4 it ispossible to select one of the serial hubs 1and 2 via one of the virtual COM ports. InDIGSI 4, when the COM port is selected, aIP point-to-point data connection via thenetwork is established and maintained be-tween the office and the relevant substationmodem until the interface is released. Theserial data exchange takes place via thisdata link, whereby the data conversionfrom serial to Ethernet is full duplex. Theoffice PC towards the network is alwaysoperating with high data rate, as the datais fed to the network via the network driveron the PC. The serial data rate of the serialhub in the substation is adapted to thebaud rate set in the protection relay, e.g.serial hub 1 with 57.6 kbit/s for SIPROTEC 4and serial hub 2 with 9.6 kbit/s forSIPROTEC 3 devices. These parametersmust be pre-set on the serial hub. WithDIGSI 4 the serial hubs are integrated bymeans of further serial COM ports(max. 254). The connection to the IP ad-dress of the serial hub in the network isachieved by opening the correspondingCOM port. If an Ethernet network to thesubstation or in the substation is available,serial data can then be transferred via thisnetwork.

The existing serial star or bus structurewith cabling in the substation can still beused.

SIPROTEC 4 devices from version 4.6 andnewer with integrated Ethernet interfacemay be connected directly to the router orswitch by means of a patch cable.

In idle state, the RS232interface is inactive while the RS485 inter-face is switched to the receiving mode.During communication, the PC (master)sends data to the RS232 interface, whichare transmitted (half duplex) to the protec-tion unit (slave) by the converter at theRS485 interface. After data transmission,the RS485 interface is once again switchedto the receiving mode. Vice versa, datasupplied by the protection unit are sentback by the converter to the RS232 inter-face and to the PC.

No handshake signals are being processedduring communication. This means thatdata sent by the PC are mirrored, whichmay cause problems in special applica-tions.

Connections

The PC is connected to the converter bymeans of a DIGSI cable e.g. 7XV5100-2.

A twisted and shielded cable with twowires is required for the RS485 bus. Theconductor cross section has to be adaptedto the ring cable lugs and the SUB-D con-nectors. The individual wires protrudingfrom the shield should be kept as short aspossible. The shield is connected to thehousing earth at both ends. The protectionunits are connected in series to the bus.The shield between the converter and theprotection units, or between the protectionunits, is connected at both sides. Wheneversubstantial cable lengths or high baud ratesare involved, a terminating resistor of220 ohm should be applied between signallines A and B at the last protection unit.Data transmission at a speed of 19.2 kbit/s,with a bus length of up to approx. 1000 m,is possible.

7XV5710USB – RS485 Converter Cable

The USB converter cable with its specialpin assignment allows temporary connec-tion of up to 31 Siemens protection deviceshaving an electrical RS 485 interface to aPC with a USB interface for direct or cen-tral control with DIGSI 4.

The converter is connected directly to thePC via a standard USB connector (type A).The RS485 connector (9-pin SUB-D male)may be used for direct connection toSIPROTEC 4 devices with RS485 interfacemodules. To connect individual compactdevices with an RS485 interface on termi-nals, e.g. 7SJ600, 7SD600, 7RW600, etc.,the 7XV5103-2AA00 or -3AA00 adapteris required. Using the gender changer(female-female), which is included, theconverter may also be connected to the7XV5103 bus system, which enables com-munication with all the devices connectedto the bus. Because the cable includes aswitchable bus termination, it may be con-nected at either end or in the middle of thebus. The converter draws all the power itneeds via the USB interface of the PC.

Data transfer

Before the converter cable is first used, aUSB driver must be installed from the CDsupplied. The driver creates a new virtualCOM port, which may then be selectedby the application, e.g. DIGSI 4. The con-verter works in half-duplex mode on themaster/slave principle.

In the quiescent state, the USB interface isinactive and the RS485 interface is ready toreceive. For communication, the PC, act-ing as the master, transmits its data to theUSB interface, which in turn forwards thedata from the converter at the RS485 inter-face to the protection device (slave). Fol-lowing this, the RS485 interface is switchedback to receive. Data coming from the pro-tection is now transmitted in the other di-rection to the USB interface and PC by theconverter. A data LED indicates when datatransfer is active.

Connection of the compact devices, e.g.7SJ600 with terminals (without bus cables7XV5103)

A shielded twisted pair (STP) cable mustbe used for the RS485 bus. The conductorcross-section must be suitable for termina-tion with ring lugs or SUB-D connectors.The protection devices are connected to thebus in line (not in star or ring topology).The core ends protruding from the shieldshould be kept as short as possible.

The shield must be connected to the hous-ing ground at both ends. At the last pro-tection device, a 220-Ω terminating resistoris connected between data cores A and B.

Termination of the RS485 bus

The RS485 bus is a two-wire bus (halfduplex) over which up to 32 devices (par-ticipants) can exchange their data on themaster/slave principle. All devices are con-nected to the bus in line (not in star or ringtopology). At the first and last devices, a220-Ω bus terminating resistor is con-nected between pin 3 (A) and pin 8 (B),irrespective of whether this is a master orslave device.

The SIPROTEC protection devices arepreferably connected to the bus as a slavebehind a master, e.g. 7XV5710 or7XV5650/51 RS484 converter. In theseconverters (1st device) the terminating re-sistor may be implemented by additionalpull-up/pull-down resistors via DILswitches (S1, S2). The “low-resistance”pull-up/pull-down resistors are essentialin various SIPROTEC bus applications,i.e. the use of other converters may resultin problems.

Fig. 15/60RS485 bus with USB converter cable 7XV5710 and several SIPROTEC devices (connection diagram)

In the protection devices, the terminatingresistor must only be activated at the lastdevice on the bus using the jumpers pro-vided for that purpose. If this is not possi-ble in the device, an external terminatingresistor, e.g. 7XV5103-5AA00 must be ap-plied behind the last device (see Fig. 15/60).

In this example, the terminating resistorsof the converter cable are active (default),the terminating resistors that are availableat some of the protection devices remaininactive. The bus is terminated after thelast device with the 7XV5103-5AA00 busterminating connector or an external resis-tor (220 Ω). If the last protection devicehas a switchable terminating resistor, thismay also be activated to ensure termina-tion.

Application

Application example

A number of SIPROTEC 3 and 4 protec-tion devices can be centrally operated viatheir interface with DIGSI via the 7XV5710USB converter cable. Suitable cables andadapters are available for the various con-nection types of the SIPROTEC devices.For more information, please refer to cata-log sheet 7XV5103. SIPROTEC 4 deviceswith an RS485 interface may be directlyconnected and operated with DIGSI 4.

For the connection of individual compactprotection devices with the RS485 inter-face on terminals e.g. 7SJ600, 7SD600,7RW600, etc.., the adapter cable7XV5103-2AA00 or the adapter7XV5103-3AA00 is required(see Fig. 15/61).

The converter cable must only be used on anon-permanent basis because of the lack ofgalvanic separation. For permanent opera-tion, the FO converters 7XV5652 and7XV5650/51 should be used. The FO con-ductor ensures complete galvanic separa-tion between PC and SIPROTEC devices.Corresponding applications may be foundat: www.siprotec.com/accessories/7XV56…

7XV5820Industrial Modem and Modem-Router with Switch

Depending on the available infrastructureand transmission requirements, variousmodems and routers are available for theremote communication with SIPROTECprotection devices using DIGSI.

The existing infrastructure may consistof analog or digital (ISDN) transmissionnetworks, which may be private (internaltelephone system) or a leased line. Thismay determine the corresponding combi-nations of the modems or routers. A suit-able combination usually consists of adesktop device with plug adapter in theoffice, and a rail-mounted device in thesubstation (see Application). The rail-mounted devices may be operated with anoptional wide-range power supply adapterwith all alternating current networks aswell as station batteries.

The desktop analog modem “Pocket 56k”as the office device and the rail-mounted“Modem 56k” in the substation ensure asecure serial data communication withSIPROTEC 3 devices using 8E1 (with paritybit) up to 19.2 kbit/s, or with SIPROTECdevices using 8N1 up to 57.6 kbit/s.

With the same analog modem “Pocket56k” in the office it possible to establish aconnection to SIPROTEC 4 devices withEN100 interfaces in a local Ethernet net-work using the rail-mounted modemrouter “MoRoS Modem 56k” in the sub-station.

Using the digital modem “Pocket ISDN”as a desktop device in the office and the“ISDN TA” as a rail-mounted device inthe substation ensures secure serial datacommunication with SIPROTEC 3devices using 8E1 (with parity bit) up to19.2 kbit/s, or with SIPROTEC 4 devicesusing 8N1 up to 57.6 kbit/s.

With the same digital modem “PocketISDN” in the office, it is also possible tocommunicate with SIPROTEC 4 deviceswith an EN100 interface module in a localEthernet network using a rail-mountedISDN router “MoRoS ISDN” in thesubstation.

Other combinations, especially with de-vices from other manufacturers are strictlynot recommended.

All versions are suitable for application incontrol systems, and substations as well asin areas of energy supply and distribution.The modems can be deployed internation-ally (certificates of approval see “TechnicalData”). As a rule, no certification is re-quired for use in internal networks.

Fig. 15/64 Remote control of SIPROTEC 3 and 4 devices over INSYS Pocket to INSYS Modem, mini star-coupleror RS485 bus with DIGSI 4

Example 1: Remote operation ofSIPROTEC 3 devices via modem

This application example illustrates remoteoperation of SIPROTEC 3 protection de-vices with an optical interface and compactprotection devices with an RS485 interfaceusing analog modems (7XV5820-1 and -5)or digital ISDN modems (7XV5820-2and -6). Connection to protection or baycontrol RTUs via an optical interface isachieved with a star configuration usingcascadable star couplers. The compact pro-tection devices with RS485 interface areconnected via a FO-RS485 converterand the RS485 bus system 7XV5103.SIPROTEC 4 devices may be connectedoptically or electrically, depending on theavailable service interface.

To ensure secure lightning protection, gal-vanic separation between the substationmodem and the protection devices mustbe implemented by means of an opticalbarrier. The substation modem with the7XV5652 RS232-FO converter is preferablylocated in a communication or controlroom while the 7XV5450 star coupler or7XV5650/51 FO-RS485 converter is lo-cated in the first protection cubicle. If theprotection devices are to be controlled cen-trally in the substation using a notebook,this is achieved by plugging a DIGSI cableinto the first star coupler, which disablesthe optical interface and enables the RS232connection.

Communication with the modems istransparent. Secure data transfer to theSIPROTEC 3 devices is achieved with thedata format 8E1 (with parity bit). The datatransmission rate depends on the slowestdevice (9.6 kbit/s or 19.2 kbit/s) and mustbe set to be equal for all devices. TheSIPROTEC 4 devices can then only be op-erated with this data rate which is relativelyslow for SIPROTEC 4.

Example 2: Remote operation ofSIPROTEC 4 devices via modem

This application example illustrates remoteoperation of SIPROTEC 4 devices with anoptical or RS485 interface via analog mo-dems (7XV5820-1 and -5) or the verymuch faster digital ISDN modems(7XV5820-2 and -6). Connection of theprotection or RTU devices with optical in-terface is achieved via cascadable star cou-plers. The devices with RS485 interfaces areconnected via the FO-RS485 converter andthe RS485 bus system 7XV5103.

To ensure secure lightning protection ofthe RS485 bus, galvanic separation shouldalways be implemented between the sub-station modem and the protection devicesby means of an optical barrier. The substa-tion modem with the RS232-FO converter7XV5652 is preferably located in a com-munication or control room while the firstFO-RS485 converter 7XV5651/50 is lo-cated in the first protection cubicle (“A1”).

If the protection devices are to be centrallycontrolled in the substation, an additionalstar coupler must be used (“A2”). By plug-ging the DIGSI cable into the first star cou-pler, the optical interface is disabled andthe RS232 connection is established. If nomini star coupler is used, central operationis only possible via the electrical interfaceof the RS232-FO converter. The modemplug must be disconnected for thispurpose.

A secure communication via the modemsis possible with the standard data format8N1, with data compression and error cor-rection. The data transmission rate is de-termined by the slowest device (38.4 kbit/sor 57.6 kbit/s) and must be set to be thesame on all devices.

This application example shows remoteoperation of SIPROTEC 4 protection de-vices with an optical or electrical EN100Ethernet interface via an analog or digitalISDN office modem, (7XV5820-1 or -2),to a modem or digital ISDN router(7XV5820-7 and -8). This router with anintegrated 4-way switch together with theRUGGETCOM switches connected via apatch cable form a local subnet.

The protection or RTU devices with opti-cal EN100 interface are connected to theRUGGETCOM switches in a ring struc-ture. The protection / RTU devices withan electrical EN100 interface are directlyconnected to the modem-router andswitch or to the electrical interfaces of theRUGGETCOM switches by means ofdouble-shielded patch cables. To minimizeany possible interference, the electricalconnections with patch cables should bekept as short as possible.

Remote connection from the office to thesubstation is established by means of apassword-protected DUN connectionunder Windows. The connection is then“transparent” and the protection devicescan be operated with DIGSI 4 in the localsubnet with their own IP addresses.

If the protection devices are to be conve-niently centrally controlled using a note-book in the substation, the notebook withan Ethernet interface can be logged intothe local subnet with a patch cable.

• DIGSI supports the administration andthe setting-up of connections via theEthernet network.

• RS232 interfaces for data transfer andconfiguration of the modem.

• Serial baud rate and data format(RS232) for the terminal devices isselectable from 2400 Bd up to 57.6 kBdwith data format 8N1, 8E1.

• An Ethernet interface LAN to the10/100 Mbit network.

• Better security with password protec-tion and IP address selection is possible.

7XV5850/5851Ethernet Modems for Office Applications

A control PC and protection units can ex-change serial data via an Ethernet networkusing two Ethernet modems 7XV585x.Connection to the Ethernet modem is ineach case made via the asynchronous serialinterface of the terminal units. In the mo-dem, the serial data is packed into the se-cure IP protocol as information data, andis transferred between the modems usingthe Ethernet connection. Conformity withthe standard and gap-free transmission ofserial DIGSI or IEC 60870-5-103/101 telegrams via the network is ensuredby the modem which receives the serialtelegram communication and packs the se-rial IEC telegrams into blocks for commu-nication via the Ethernet. The data istransmitted in full duplex mode; serialcontrol wires are not supported. Connec-tion is established between the IP addressof the dialing modem in the office and theIP address of the pick-up modem in thesubstation, and is configured prior to dial-ing up with DIGSI by means of AT com-mands via the RS232 interface.

The substation modem may be configuredto have password protection, and providesthe additional security feature, whereby ac-cess is only permitted from defined IP ad-dresses, e.g. only that of the office modem.The modem is accessed with DIGSI Re-mote like a normal telephone modem withthe exception that instead of telephonenumbers, IP addresses are assigned by thenetwork administrator for each modem.

Using the office computer and DIGSI 4,both substation 1 and 2 may be dialed upvia Ethernet modems. A TCP/IP point-to-point data connection is established be-tween the office modem and correspond-ing substation modem when dialed up viathe network. This is maintained until theoffice modem terminates the connection.The serial data exchange takes place via thisdata connection, with the modem convert-ing the data from serial to Ethernet withfull duplex mode. Between the office mo-dem and the office PC, the highest baudrate is always used, e.g. 57.6 kB forSIPROTEC 4 units. The serial baud rate ofthe substation modem is adapted to thebaud rate required by the protection relays,e.g. substation modem 1 with 57.6 kB forSIPROTEC 4 and substation modem 2 with9.6 kB for SIPROTEC 3 units. These set-tings are only defined once in the modem.The Ethernet modems are integrated inDIGSI 4 similar to telephone modems. In-stead of the telephone number, the pre-setIP address assigned to the modem is se-lected.

If later an Ethernet connection is availablein the substation, the existing modem canbe replaced by an Ethernet modem. Theentire serial bus structure and cabling mayremain unchanged.
