The DNP 3.0 Master protocol driver exists in a single port (DNPM)
implementation only. The DNPM port operates in a Master mode only, supporting
the DNP 3.0 protocol in a Level 2 implementation.
The DNP Master driver is implemented in ProLinx communication modules to
interface DNP slave units with a variety of communication protocols and
interfaces. This driver supports DNP version 3.0, subset level 2. The Reference
chapter of this documentation contains the Device Profile for the driver. The
Reference chapter contains the subset definition for the driver. This document
serves as the base for understanding the DNP Master driver functionality and
configuration. The discussion is general in nature deferring specifics to the
individual product documents.
Before attempting to use this or any other DNP protocol device, verify that you
have a copy of the DNP Basic 4 document and other information available
through the DNP User Group. It is very important that these documents be
understood for successful application of the protocol in a user’s solution. If you
are a member of the user group, you can download these documents from the
http://www.dnp.org (http://www.dnp.org) web site.
All data in the module’s database configured as DNP data points is available to
the remote devices for read and write requests. This permits other devices
connected to the ProLinx unit to monitor and control DNP slave devices
connected to the master port.
