Spontaneous Transmission:
 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.
 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_1
Station interrogation:
Clock synchronization:
 Clock synchronization (optional, see Clause 7.6)
Command transmission:
 Direct command transmission
 Direct setpoint command transmission
 Select and execute command
 Select and execute setpoint command
 C_SE ACTTERM used
 No additional definition
 Short pulse duration (duration determined by a system parameter in the outstation)
 Long pulse duration (duration determined by a system parameter in the outstation)
 Persistent output
 Supervision of maximum delay in command direction of commands and setpoint commands
Maximum allowable delay of commands and setpoint commands: 10 s
Transmission of integrated totals:
 Mode A: Local freeze with spontaneous transmission
 Mode B: Local freeze with counter interrogation
 Mode C: Freeze and transmit by counter-interrogation commands
 Mode D: Freeze by counter-interrogation command, frozen values reported simultaneously
 Counter read
 Counter freeze without reset
