PLX51-HART-4I

HART Module

PLX51-HART-4I

The PLX51-HART-4I allows users to easily connect their existing HART-compatible field devices to EtherNet/IP™, Modbus® TCP/IP, and DNP3 Ethernet networks. The module can be used to connect HART Input devices such as process instruments into an Ethernet network. 

The PLX51-HART-4I supports up to 4 channels of HART communication, as well as Analog 4-20 mA signals for real-time process variables to/from the HART-compatible device.

Features and Benefits

  • Support for point-to-point and Multi-drop (maximum of 15 devices) HART networks
  • EtherNet/IP enables a HART device to be added directly into a Rockwell Automation® Logix I/O tree
  • Modbus TCP/IP enables a HART field device to be viewed as a Modbus Slave device
  • DNP3 converts a HART field device into a DNP3 Outstation (slave) supporting Secure Authentication
  • DTM (Device Type Manager) / HART Pass-through is available for further simplifying device configuration and management using an FDT frame
  • Built-in webserver provides detailed diagnostics of system configuration and operation as well as field device diagnostics
  • Direct-to-tag technology with EtherNet/IP
  • Can be used in a redundant ControlLogix® controller system
  • Built-in packet analyzer for HART networks
