Description

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 and Benefits

  • 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 troubleshooting 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.
