No Logix or remote device configuration is required.
Unscheduled The DNP3 Router transfers messages received from a Logix Message
Instruction.

Table 1.1. – Modes of Operation
The
DNP3
Router is configured using the Aparian Slate application. This program can be
downloaded from www.aparian.com free of charge. Slate offers various configuration
methods, including a controller tag browser.
Hereafter the
DNP3
Router will be referred to as the module .
The module can operate in both a Logix “owned” and standalone mode. With a Logix
connection the input and output assemblies will provide additional diagnostics information
which will be available in the Logix controller environment.
The DNP3 Router allows the user to integrate DNP3 devices into a Logix system with minimal
effort. No copying or mapping of data in the Logix controller is required as the DNP3 Router
writes directly into Logix tags.
The DNP3 Router also provides DNP3 Secure Authentication 5 which enables the user to
connect DNP3 devices to a Logix platform securely. The module also provides a range of
statistics and traffic analyser to help fault find any problems.
The DNP3 Router supports DNP3 on three ports which can be configured from the Slate
environment; Serial, Ethernet TCP, or Ethernet UDP.
Previously complicated data mapping is made easy by precompiled UDTs which converts the
various DNP3 data formats into sensible data in the Logix environment.
The module uses isolated RS232 for
DNP3 serial
communication providing better noise
immunity. The RS232 port also uses a terminal block for convenient installation.
A built-in webserver provides detailed diagnostics of system configuration and operation,
including the display of
DNP3 operation and
communication statistics, without the need for any
additional software.
