Prosoft PLX51-DNPM Distributed Network Protocol (DNP3) Master Gateway

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.

The PLX51-DNPM can be configured to operate in these modes:

 Master – The PLX51-DNPM communicates to DNP3 slave devices

and transfers the data to an EtherNet/IP- or Modbus-based PLC.

 Data Concentrator – The PLX51-DNPM will act as a master and

outstation. The module will be a master to other DNP3 slave devices

and then an outstation to the DNP3 SCADA Master.

Features

 Peer-to-peer communications

 Supports DNP3 Secure Authentication v5

 Supports EtherNet/IP, and Modbus Master and Slave protocols (TCP/IP and RTU)

 Supports DLR (Device Level Ring) for EtherNet/IP Networks – enables

ring topology with provides network resiliency

 Onboard storage for > 1.3M DNP3 Events

 Support for unsolicited reporting

 Disaster recovery via the microSD Card

 DNP3 Level 3 compliant

 The PLX50 Configuration Utility software is used for configuration and trouble

shooting of the module. The stand-alone

configuration utility allows users to define the setup and configuration of the 

PLX51-DNPM gateway, and connections with controllers and devices.
