IEC 60870-5 Client And Server (Master And Slave)
Telecontrol ProtocolIEC 60870-5 Client and Server(Master and Slave)For communication in accordancewith IEC 60870-5-101, -103 and -104Application areasThe remote control protocol, according to standardsIEC 60870-5-101 and IEC 60870-5-104, is widelyused in power generation, power distribution andinfrastructure areas. They enable the control andmonitoring of intelligent sub-components and substations through a superordinate control center.The palette of these sub-components ranges fromcircuit breakers, converters, and energy meters tocogeneration units up to complete power plants. TheIEC 60870-5-103 standard was defined especially forcommunication with protective devices.Control stationPlant / field levelProcessSolutionCenterusdbiel,FI/OIEC 60870-5-101, -103:Serial RS232, 422, 485IEC 60870-5-104: EthernetM1-CPUFMProduct featuresThe IEC 60870-5 service is installed purely as asoftware component on the controller and requiresno special hardware. It uses the serial interfaces(-101, -103) or the Ethernet ports (-104) availableon the controller. Through configuration of multipleinstances, simultaneous operation of -101, -103, and/or -104 is possible; the function as master or slavecan be selected per instance. It is possible to connectmultiple external masters by creating multiple slaveinstances. Multiple redundant masters are alsopossible for each instance.ItemIEC 60870-5-Server RTIEC 60870-5-DownloadIEC 60870-5-Client RTIEC 60870-5 Server/Client RTIEC 60870-5 Redu-Server RTIEC 60870-5 Client/Redu-Server RTItem 27197-6300027198-63254System Overview Bachmann electronic GmbH 11/2019 Specification subject to change –the product’s characteristics are exclusively governed by the data of the respective user manual.
Telecontrol ProtocolClient (Master)Each instance of the master connectsautomatically to the assigned external slavedevice, sends a general interrogation and receivesthe interrogated values as well as the valuestransmitted spontaneously from the slave. Thesevalues are represented as channel values and areavailable to the user immediately without anyadditional programming effort. Values can be sentin the direction of the command by simply writingto an output channel. As a result, the slave can beoperated as easily as a local I/O module.Event-driven reception of the slave data ispossible for more complex applications. Additionallibrary functions are available for special functionssuch as setting the time of the slave, meterreadout etc.PC Configuring Parametrizing MonitorEthernet, TCP/IP:FTP, SMIM1 controllerSW modulesC/C Process dataConfigurationAdresses andserver objects,mappingon process dataSW modulesPLC with process imageLogicalmoduleLogicalmoduleLogicalmoduleIEC 60870-5 Client software (Master)-104 (TCP/IP)-101, -103 (serial)IEC 60870-5-104Server (Slave)IEC 60870-5-104Server (Slave)IEC 60870-5-101or -103Server rocessSoftware interfaceHardware interfaceBlock diagram IEC 60870-5 Client255System Overview Bachmann electronic GmbH 11/2019 Specification subject to change –the product’s characteristics are exclusively governed by the data of the respective user manual.
Telecontrol ProtocolServer (Slave)The information objects that the server offers inthe command and monitoring direction, are linkedto the controller with existing process variables, viathe configuration. No change to the programmingcode is necessary for this. A different data modelcan also be created for different clients.SolutionCenterConfigurator/MonitorPC, Visu,60870controlMasterstation etc.60870Master60870MasterEthernet TCP/IPM1 controllerEthernetTCP/IPConfigurationObject modelData mappingSerial COM portsIEC 60870-5 ServerCommunication according to-101, -103, -104SVISoftware ModulePLC, C/C ProcessMIOSensorActuatorBlock diagram IEC 60870-5 Server256System Overview Bachmann electronic GmbH 11/2019 Specification subject to change –the product’s characteristics are exclusively governed by the data of the respective user manual.Monitor directionPC Configuring Parametrizing MonitoringControl directionTo reduce the communication load, a threshold filtercan be enabled. Values that are outside of definedMin/Max limits are marked as invalid and will onlybe transferred again when they return to the validrange. No implementation by the user is necessaryfor this. A monitor in the SolutionCenter shows thecurrent configuration of information objects used inthe server, and the value most recently transmittedto the client.The log-in of clients can be restricted by specifyinga permitted IP address, and the number ofsimultaneous client connections can also be limited.Write accesses can be captured in the security logof the controller; the user-dependent managementof access rights is also effective for IEC 60870.

Thelink to the process data takes place by selectingthe corresponding SVI variables from a variablebrowser. To exchange the configuration using othertools, import and export functions of a generic CSVformat are available.AdvantageExisting software for sequence control andregulation does not need to be changed and willnot be affected in its runtime. Thus it can beflexibly responsive to final customer requirementswithout changing the existing tested software forcontrol and regulation of the substation. Throughrealization as a finished server with integratedupdate- and threshold logic, tedious replication ofthe protocol functions via limiting PLC-libraries, andthe associated training efforts in the standard, iseliminated. Engineering and testing time can thusbe reduced, and the integrated diagnostics shortenthe troubleshooting in the event of malfunctionsduring operation.The diverse communication possibilities via fieldbusses and real-time Ethernet, the broad rangeof signal interfaces to grid measurement, as wellas powerful mass storage make the M1 systemin conjunction with the remote control protocolof the series IEC 60870-5-10x ideally suitablefor use as a control device, central control, dataconcentrator, datalogger and gateway.Technical data Standard compliant implementation ofIEC 60870-5-101, -103, -104 client and server Subsequently installable service/softwaresolution No changes to the application logic required Fully configurable/no application-specificprocessing via PLC libraries required Configurator for commissioning and diagnosticmonitor in the SolutionCenter Import/export of the slave configuration in CSVformat for exchange with other manufacturers Reducing the amount of data via configurablethreshold filters Number and IP addresses of authorized clientscan be limited Logging of write accesses in the security log ofthe controller Easy and fast start-up including diagnosiswithout any programming effort The remote control protocol can be operated likea simple I/O moduleSystem Overview Bachmann electronic GmbH 11/2019 Specification subject to change –the product’s characteristics are exclusively governed by the data of the respective user manual.257

Alex Rider was woken by the first chime. His eyes flickered open, but for a moment he stayed completely still in his bed, lying on his back with his head resting on the pillow. He heard a bedroom door open and a creak of wood as somebody went downstairs. The bell rang a second time, and he looked at the alarm clock glowing beside him. There was a rattle as someone slid the security chain off .
