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 PLC’s, HMI's, Drives, or Flex I/O adapters.

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

The AN-X4-AB-DHRIO has a built-in webserver to view diagnostics, current configuration, upload configuration files, and set the operating mode. It is also DIN Rail Mountable.

The operating mode acts as a bridge between an EtherNet/IP and a DH+ 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).


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

  • Support gathering data without changing existing PLC or SLC hardware



This operating mode allows legacy PanelViews to be upgraded to a PanelView Plus 6 or PanelView Plus 7 via EtherNet/IP.

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



This operating mode supports upgrading legacy Allen Bradley drives on Remote I/O to new EtherNet/IP-enabled drives.

  • No changes to PLC code required
  • Supports up to 4 EtherNet/IP drives
  • Configurable with ¼, ½, and full rack addressing
  • Supports all PowerFlex drives on EtherNet/IP.


Flex I/O Scanner

This operating mode allows PLC’s on Remote I/O to connect to and control 1794-AENT EtherNet/IP Flex adapters.

  • Designed to replace obsolete 1794-ASB adapters
  • Supports up to 16 EtherNet/IP connections
  • Each adapter and rack of discrete counts as a single connection. Each analog module counts as a single connection.
