APPENDIX E
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

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
