The PLX51-DNPM gateway provides intelligent routing between DNP3

(Distributed Network Protocol) and either EtherNet/IP™ or Modbus®

protocols. The gateway supports Ethernet and Serial communications.

The PLX51-DNPM gateway is a DNP3 Master.

The gateway allows the user to integrate DNP3 devices over a secure

link into a Rockwell Automation® Logix system with minimal effort. No

copying or mapping of data in the Logix controller is required, as the

PLX51-DNPM writes directly into Logix tags.

The PLX51-DNPM allows users to integrate the gateway into a Modbus

TCP/IP or serial network. The gateway supports Modbus TCP/IP Client

and Server and Modbus RTU protocols.

The module provides DNP3 Secure Authentication v5. which enables the

user to connect DNP3 devices to a Logix platform securely. The module

also provides a range of diagnostics and statistics, as well as a DNP3

traffic analyzer to assist with fault-finding.
