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_1
Double point information: M_DP_NA_1, M_DP_TA_1, and M_DP_TB_1
Step position information: M_ST_NA_1, M_ST_TA_1, and M_ST_TB_1
Bitstring 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_1
Measured value, scaled value: M_ME_NB_1, M_ME_TB_1, and M_ME_TE_1
Measured value, short floating point number: M_ME_NC_1, M_ME_TC_1, and M_ME_TF_1Station interrogation:Clock synchronization:4 Clock synchronization (optional, see Clause 7.6)Command transmission:4 Direct command transmission
