The SINAUT Configuration Tool
6.6 TD7onTIM
TIM DNP3
System Manual, 12/2015, C79000-G8976-C253-04

Specifying the data type specifies how the data of the S7 CPU is interpreted and transmitted
to the communications partner.
The number of required elements, in other words the size of the data field is configured in
the Number input box.
The configured number of values specifies how many DNP3 indexes are occupied
consecutively by the object starting with the specified start index. The following assignment
between the data type used and the index used applies:
Number of DNP3 indexes
occupied
CHAR Printable ASCII characters 4 ... 48
-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 of TD7onTIM (Page 177).
Note
Reducing network load
By reducing the maximum size (parameter “Number”), the message length can be reduced
to the actually required length if the entire data range of the object is not required. This saves
transmission time.
Dat12D_R
Channel "DataOutput"
Channel type: Data receive
Dat12D_R allows receipt of data with a size of up to 12 double words.
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.
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 number of required elements, in other words the size of the data field is configured in
the Number input box.
