DNP3 Serial Slave 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.

DNP3 Serial Slave Gateway
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.
Features and Benefits
- Support DNP3 Secure v5
- Supports EtherNet/IP, Modbus Master and Slave protocols (TCP/IP and RTU)
- Supports DLR for EtherNet/IP Networks
- On board storage for 900,000 DNP3 Events
- Support for unsolicited reporting
- Disaster recovery via the microSD Card
- DNP3 Level 3 compliant
Configuration
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-DNPS gateway, connections with controllers and devices.
