PLX51-DNPS

Distributed Network Protocol (DNP3) Gateway

PLX51-DNPS

The PLX51-DNPS gateways provide intelligent routing between DNP3 (Distributed Network Protocol) and either EtherNet/IP™ or Modbus® protocols. The gateways support Ethernet and Serial communications.

PLX51-DNPS gateway is the DNP3 Outstation or Slave.

The PLX51-DNPS allows the user to integrate DNP3 devices over a secure link into a Logix system with minimal effort. No copying or mapping of data in the Logix controller is required as the PLX51-DNPS writes directly into Logix tags.

The PLX51-DNPS 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 PLX51-DNPS module 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 diagnostics, statistics and a DNP3 traffic analyzer to assist with fault-finding.
