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