GE Multilin D60 Line Distance Relay D-7APPENDIX D D.1 IEC 60870-5-104 PROTOCOLD6. BASIC APPLICATION FUNCTIONSStation Initialization:Remote initializationCyclic Data Transmission:Cyclic data transmissionRead Procedure:Read procedureSpontaneous Transmission:Spontaneous transmissionDouble transmission of information objects with cause of transmission spontaneous:The following type identifications may be transmitted in succession caused by a single status change of an informationobject. The particular information object addresses for which double transmission is enabled are defined in a project-specific list.Single point information: M_SP_NA_1, M_SP_TA_1, M_SP_TB_1, and M_PS_NA_1Double point information: M_DP_NA_1, M_DP_TA_1, and M_DP_TB_1Step position information: M_ST_NA_1, M_ST_TA_1, and M_ST_TB_1Bitstring of 32 bits: M_BO_NA_1, M_BO_TA_1, and M_BO_TB_1 (if defined for a specific project)Measured value, normalized value: M_ME_NA_1, M_ME_TA_1, M_ME_ND_1, and M_ME_TD_1Measured value, scaled value: M_ME_NB_1, M_ME_TB_1, and M_ME_TE_1Measured value, short floating point number: M_ME_NC_1, M_ME_TC_1, and M_ME_TF_1Station interrogation:Clock synchronization:Clock synchronization (optional, see Clause 7.6)Command transmission:Direct command transmissionDirect setpoint command transmissionSelect and execute commandSelect and execute setpoint commandC_SE ACTTERM usedNo additional definitionShort pulse duration (duration determined by a system parameter in the outstation)Long pulse duration (duration determined by a system parameter in the outstation)Persistent outputSupervision of maximum delay in command direction of commands and setpoint commandsMaximum allowable delay of commands and setpoint commands: 10 sGlobalGroup 1 Group 5 Group 9 Group 13Group 2 Group 6 Group 10 Group 14Group 3 Group 7 Group 11 Group 15Group 4 Group 8 Group 12 Group 16
