Spontaneous transmission

Double 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 information
object. The particular information object addresses for which double transmission is enabled are defined in a project-
specific list.
Ë
Single point information: M_SP_NA_1, M_SP_TA_1, M_SP_TB_1, and M_PS_NA_1
Ë
Double point information: M_DP_NA_1, M_DP_TA_1, and M_DP_TB_1
Ë
Step position information: M_ST_NA_1, M_ST_TA_1, and M_ST_TB_1
Ë
Bitstring of 32 bits: M_BO_NA_1, M_BO_TA_1, and M_BO_TB_1 (if defined for a specific project)
Ë
Measured value, normalized value: M_ME_NA_1, M_ME_TA_1, M_ME_ND_1, and M_ME_TD_1
Ë
Measured value, scaled value: M_ME_NB_1, M_ME_TB_1, and M_ME_TE_1
