DNP3 OPERATION

5.1.

GENERAL

DNP3 supports various formats for each group of data points. The different formats can
include additional data to that of the main requested variable needed (e.g. Status, Time, etc.).
For this reason, the Logix controllers needs to map the data for these formats to User-Defined
Data Types (UDTs). A range of UDTs have been provided to the user allowing for easy and
seamless integration with the Logix Controller. Below are some examples of how these UDTs
should be used.

When DNP3 group 30 (analog inputs) has been selected there is a range of variations that can
be used providing different format and additional information for the user. If variation one
(1) was selected Slate would indicate that the data returned will be a 32-bit number with a
Flag (or Status bits) as shown below:

Figure 5.1. – DNP3 Group 30 selected with Variation 1

Next the user must select the correct UDT provided in the example RSLogix 5000 project (see
the Additional Information section for further details). In this case the example project has a
UDT called

AparianDNP3AnalogInput32Flag

which should be used as this will correctly map

the additional information from the DNP3 Object as shown below. The UDT is shown below:
