Implementation of DNP3 elements in TD7onTIM
Overview of the elements with DNP3 and TD7onTIM
The DNP3 protocol specifies various elements for addressing subscribers and for classifying
and identifying data to be transmitted. Below you will find an overview of how the DNP3
elements are implemented in the corresponding elements of the TD7onTIM communications
software.

Station address
The station address on the data link layer is the
address of a subscriber in the DNP3 network.
Subscriber number
The communications partner in the DNP3 net-
work is addressed using the subscriber number.
The subscriber number is assigned automatically
but can be modified manually, refer to the section
Subscriber list (Page 150).
Point
Uniquely identifiable physical or logical unit
Data point
Smallest data unit that corresponds to a binary or
analog process input or output or a calculated
value.
Point Index
The index is used for the unique identification of a
data point.
Index
The index is adopted in TD7onTIM.
Note:
Refer to the information in the section Configuring
the index (Page 160).
Object
Coded representation of data point or another
data unit for transmission.
Data object
The data points are also configured in objects for
TD7onTIM. The objects are assigned to the sub-
scribers from the TD7onTIM library in the
SINAUT configuration tool.
Group
Objects are grouped according to the following
criteria:
• Signal type (binary, analog, counter, time info)
• Transmission direction (input, output)
• Transmission type (read, event)
Other groups are defined for special tasks.
Object group
The most important object groups for the transfer
of process data are adopted in TD7onTIM.
The signal type and transmission direction are
specified by the type of the data object.
The transmission type is specified in the chan-
nels; refer to the lower part of the table.
Variation
Variations further specify the object groups ac-
cording to the data format.
-
There is no direct counterpart for variations in
TD7onTIM. The data format is specified by the
data object.
