AN-X4-AB-DHRIO Gateway

EtherNet/IP™ to DH+ Gateway


The AN-X4-AB-DHRIO Gateway is designed to help customers initiate a phased migration approach to replacing or upgrading legacy PLCs and HMI terminals.

These solutions can be achieved by selecting the corresponding operating mode during the initial configuration.

The AN-X4-AB-DHRIO has a built-in web server that can view diagnostics and current configuration, upload configuration files, and set the operating mode. Desktop use or DIN Rail Mountable.

Architecture 01 - This operating mode acts as a bridge between an EtherNet/IP and a Data Highway Plus network.

  • Programming terminals, and/or processors on an EtherNet/IP network can access legacy processors on a DH+ network
  • Download to a PLC5 or SLC through RSLinx
  • Configured through web browser
  • Supports all DH+ baud rates (57.6, 115.2, and 230.4 K baud)


Architecture 02 - This operating mode helps the communication between an Ethernet-Based processor with legacy processors on a DH+ network.

  • Help gather data without changing existing PLC or SLC hardware



Architecture 03 - This operating mode allows legacy PanelViews to be upgraded to a PanelView Plus6 or PanelView Plus7 via EtherNet/IP.

  • No changes to PLC code required
  • Supports up to 8 PanelViews on the same network
