Energy Measurement and ManagementP2CCommunicator

P2CThe P2C communicator is intended for remote readout of electricity meters on the level of industrial consumption according to the protocol complyingto the IEC 61107 standard. It enables bi-directional data transmission from a meter to a data processing centre and vice-versa. The communicatoris provided with two communication interfaces - one for the access to the meter, and another for data transmission to the billing centre. The communicatorreads meters via CS interface (20 mA current loop by DIN 66348) or via RS 232 interface. Data are sent to the centre via various communicationmedia (PSTN, ISDN, GSM or CaTV network). The SEP2W software enables parameter setting and readout of the communicators aswell as data processing. The device can also be read out by means of other programs that support the IEC 60870-5 protocol.The communicator is made in two versions due to different requirements and communication interfaces:P2CA - communication interface: it is intended for remote readout of meters according to the IEC 61107 protocol - C mode without data transmission rate changeP2CB - communication converter: a microprocessor based device which enables meter reading according to the protocol which complies with theIEC 61107 standard - A, B, C and D modesCOMMUNICATOR FUNCTIONSCommunication interface to meterCommunication interfaces to centreData acquisitionGeneration of control signalsReal time keeping andsynchronisationIndication of device operationP2CA– RS232– PSTN modem– ISDN modem– GSM modem– on request from thecentre, data from themeter are transmitteddirectly to thecentre via a communicator5 LEDs• RUN• RTS• TxD• RxD• DCDP2CB– CS interface (20 mA current loop)– PSTN modem– ISDN modem– GSM modem– CaTV modem– on request from the centre, data are transmitted from themeter to the centre via a communicator– a communicator reads data from the meter regularly in settime intervals and stores them into its memory. Whenrequested from the centre, data are transmitted from theinternal memory to the centre– Termination of a billing period– a built-in real time clock; it can be synchronised viacommunication channels6 LEDs• RUN• ALARM• IR• Modem• CS 1• CS 2Transmission of request fromthe data processing centre tothe meterThe communicator enables datatransmission from the data processingcentre to the meter. Differentrequests can be transmitted to themeter from the centre like the requestfor data reading or termination of thebilling period; parameters can be setin the meter from the centre.Master / slave configurationThe cascade function enables connectionof several devices to thenetwork. The master communicatorin the network is provided with abuilt-in communication interface forconnection with the data processingcentre. The master device transfersthe received data to the slavedevices and their data to the centre.In this way the access to severalcommunicators is enabled via onetelephone line.Data transmission to theconcentrator or centreA built-in exchangeable communicationinterface (a modem) transmitsdata to the centre. The followinginterfaces can be built into thecommunicator:– PSTN for data transmission overa public analogue telephone network,– ISDN for data transmission over apublic digital telephone network– GSM for transmission through amobile digital network (whenother telephone network is notavailable)– CaTv for transmission over acable TV network (only at P2CBversion).A primary protocol for datatransmission complies to theIEC 60870-5 (DIN 19244 andIEC 60870-5-102) standard. Thedevice enables data transmission onrequest; it answers the calls. Thecommunicator can also automaticallycall the data processingcentre in case of events, e.g.: a timealarm (at a certain moments), a callback function, data transmission onthe meter request, or after the billingperiod termination.TECHNICAL DATAHardware P2CA P2CBCPUyesReal time moduleoptionCS interface 2Outputs (bi-stable relay)1 (for billing period reset)PSTN modem 1* 1*IISDN modem 1* 1*CaTV modem 1* 1*GSM modem 1* 1*RS 4851 (option)Optical interfaceyesLED indicators Ja yesPower supply 230 V 230 V* One modem can be built-in at time.Owing to periodical improvements of our products the supplied products can differ insome details from the data stated in the prospectus material.722.999.184 9910/55Iskraemeco, Energy Measurement and Management4000 Kranj, Savska loka 4, SloveniaTelephone: (+386 64) 26 40, Telefax: (+386 64) 26 43 76, http://www.iskraemeco.siPublished by Iskraemeco.
