Sepam Series 10 - Functions and ParametersCommunicationApplicable toSepam Series 10N B ACommunicationProtocolsSelecting theCommunicationProtocolSetting theModbus ProtocolParametersSepam series 10 A relays are equipped with an RS 485 communication port.By default they operate with Modbus protocol. The IEC 60870-5-103 protocol can also be selected.Refer to Communication, p. 169.The communication protocol is selected in the parameters menu (PROTOCOL screen).The next screen in the parameters menu contains the setting parameters corresponding to the selectedprotocol.The Modbus protocol parameters are set in the parameters menu (MODBUS screen).These parameters are described in the table below:ParametersAuthorized ValuesAddress 1...247Transmission speed• 4800 Baud• 9600 Baud• 19200 Baud• 38400 BaudParity• None (2 stop bits)• Even (1 stop bit)• Odd (1 stop bit)Remote control order• DIR: Direct mode remote control order• SBO: Confirmed (Select Before Operate) mode remote control orderSetting theIEC 60870-5-103ProtocolParametersThe IEC 60870-5-103 protocol parameters are selected in the parameters menu (IEC 870-5-103screen).These parameters are described in the table below:ParametersAuthorized ValuesAddress 0...254Transmission speed• 4800 Baud• 9600 Baud• 19200 Baud• 38400 BaudParity• None (2 stop bits)• Even (1 stop bit)• Odd (1 stop bit)Local/RemoteCheckSepam series 10 A manages local/remote mode, to authorize or inhibit actions by the communicationport.In standard mode, logic input I4 is assigned to the local/remote mode data item. If this input is active,remote control orders are not taken into account, except for remote opening orders. A setting in theparameters menu can be used, if necessary, to inhibit the remote opening order in local mode.For more information, refer to Operation of the Local/Remote Check, p. 139.In custom mode, the local/remote logic input can be assigned to logic inputs I3 or I4.132 SEPED307003 02/2008
