5. DNP3 Definitions
5.1 Device Profile
The following table provides a “Device Profile Document” in the standard format defined in the DNP 3.0 Subset
Definitions Document. While it is referred to in the DNP 3.0 Subset Definitions as a “Document,” it is in fact a table, and
only a component of a total interoperability guide. The table, in combination with the Implementation Table provided
in Section 5.2 (beginning on page 50), and the Point List Tables provided in Section 5.3 (beginning on page
56), should provide a complete configuration/interoperability guide for communicating with a device implementing
the Triangle MicroWorks, Inc. DNP 3.0 Slave Source Code Library.
