The SINAUT Configuration Tool

TIM DNP3
218 System Manual, 06/2014, C79000-G8976-C253-03
Dat12D_R allows receipt of data with a size of up to 12 double words. The configured
number of values specifies how many DNP3 indexes are occupied consecutively by the
object starting with the specified start index.
Setting the data type specifies how the data of the communications partner will be
interpreted and in the case of the station transferred to the S7 CPU.
The master station can send all variations of the DNP3 object group "Analog output". If the
transferred analog value is outside the range of validity of the configured data type, this
value is not transferred to the S7 CPU. A negative acknowledgement is sent to the master
station.
The following assignment between the data type used and the DNP3 indexes used applies:
Number of DNP3 indexes
occupied
-2 147 483 648 ... 2 147 483 647
38
38
You will find the DNP3 object groups compatible with the individual data types in the section
Objects: Overview table (Page 180).
For information on reducing the message length with the "Number" parameter in the output
address box, refer to the description of the Dat12D_S object above.
Note
Configuring counted values as an event
For reliab
le transmission, counted values should always be assigned to an event class, for
example event class 3. If counted values are only transferred as static unacknowledged
DNP3 data, if there are communications problems, it is possible that these will not be
t
ransferred consecutively to the DNP3 master station.
Channel type: Counted value send
The object always occupies 1 or 4 indexes (1 index per activated channel).
Cnt01D_S sends 1 counted value, Cnt04D_S sends 4 counted values to a DNP3 master
station.
The objects can only be used in the station.
