AN-X-AB, EtherNet/IP to A-B DH+ or Remote I/O Scanner/Adapter

EtherNet/IP to Allen Bradley Remote I/O or DH+ Gateway


The EtherNet/IP to Remote I/O or DH+ (AN-X2-AB-DHRIO) Gateway is designed to help customers initiate a phased migration approach to replacing or upgrading legacy Remote I/O, HMI's or Drives. The AN-X2-AB-DHRIO gateway has multiple operating modes that are selected during initial configuration and are described below.

Note: Now supports DH+ migrations on SLC networks. Some PLC code change may be required see TN143269-001 DH+ to EIP PV Migration for SLC networks.pdf for more information.

Remote I/O Scanner Features:

This operating mode allows users to replace their existing Remote I/O PLC with a ControlLogix or CompactLogix PAC without having to replace existing racks of I/O.

  • Build new controller program without interrupting existing controls, minimizing downtime
  • All Remote I/O baud rates are supported (57.6, 115.2, and 230.4 K baud)
  • Supports all Remote I/O baud rates (57.6, 115.2, and 230.4 K baud), and Remote I/O addressing 0-76 octal
  • Works with both ControlLogix or CompactLogix
  • Auto-Configuration utility discovers baud rate and maps discrete I/O reducing configuration errors


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 1/4, 1/2 and full rack addressing
  • Supports all PowerFlex drives on EtherNet/IP



This operating mode supports legacy HMI's on Remote I/O to be upgraded to a PanelView Plus or PanelView Plus 6 on EtherNet/IP.

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


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)

Remote I/O Adapter

This operating mode allows PLC's on Remote I/O to share data with a newer ControlLogix or CompactLogix PAC's. This mode also allows a ControlLogix processor to monitor Block Transfer and I/O data on an active Remote I/O network without occupying a drop.

  • Supports up to 15 EtherNet/IP I/O connections to a Logix Processor
  • Supports any combination of Remote I/O rack addressing
  • Auto configures rack addressing and baud rate

Web Access

AN-X2 has a built-in web server. A web browser can view diagnostics, current configuration, upload/download configuration files,
and set operation mode.
