Remote I/O Scanner

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 programs without interrupting existing controls, minimizing downtime

Supports up to 32 racks of Remote I/O

Supports all Remote I/O baud rates (57.6. 115.2. and 230.4 K baud), and Remote I/O addressing 0 to 76

octal

Auto-Configuration utility discovers baud rate and maps discrete I/O, reducing configuration errors

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 16 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

Bridge Mode

This operating mode allows the module to listen to all messages on an Ethernet network and

use its “BridgeIP” mapping to forward the messages out of the DH+/BH port. 

The messages received on the DH+/BH port can be forwarded to the devices connected to its Ethernet

port.

Allows the use of existing Blue Hose cabling for EtherNet/IP communication:

I/O to Controllers

HMI to SCADA

Programming Controllers via PC

Support for up to 64 AN-X4-BRG, each on different Ethernet network

DH+ mode supports up to 230k Baud Rate

Blue Hose mode supports up to 460K Baud Rate

HMI

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.

Drive

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.

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.

Specifications

DH+ to EtherNet/IP™

1/ 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).

2/ 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

DH+ to Modbus TCP

This operating mode allows Modbus TCP Clients to access the PLC data from stations on a Data Highway

Plus Network.

The Modbus TCP server supports up to 128 connections

Modbus Input and Output Registers are mapped to the PLC/SLC files for each station

Modbus TCP Unit/Slave ID data is mapped to the Data Highway Plus Station

Cabling and Termination

Follow Allen-Bradley cabling recommendations for remote I/O. Refer to Approved

Vendor List for DH, DH+, DH-485. and Remote I/O Cables, publication ICCG-2.2.

February 1996.

On the AN-X module, the connections should be line 1. shield, line 2.

Ethernet Configuration

The AN-X2-ABRIO-EIPSCN module connects a controller on remote I/O such as a

PLC-5 to scan I/O modules on Ethernet.

Before you can use the AN-X2-ABRIO-EIPSCN, you must configure its network

properties on Ethernet.

Ethernet Configuration

AN-X can be configured:

• to use a static (unchanging) IP address

• to obtain its IP address from a DHCP server

• to use the fixed link-local address 169.254.42.84

AN-X modules are shipped with the link-local address 169.254.42.84.

Unless you have control of the DHCP server, in most applications you will assign the

AN-X a static IP address. Otherwise the DHCP server may assign a different IP address

each time AN-X powers up, and any software that accesses the AN-X module would have

to be reconfigured.

If you are using multiple AN-X modules, connect and configure one at a time, since

initially they will all be set to the same link-local IP address.

AN-X2 Modes of Operation

There are two AN-X2 modes of operation:

• Maintenance mode. The AN-X2 runs the maintenance firmware at startup. It

performs diagnostics (memory tests, etc), copies any changes from the microSD card.

If there are no errors, it starts the AN-X2 in production mode.

• Production mode. This is the normal runtime mode of operation.

Prevent Electrostatic Discharge

The module is sensitive to electrostatic discharge.

WARNING!

Electrostatic discharge can damage integrated circuits or

semiconductors. Follow these guidelines when you handle the module:

• Touch a grounded object to discharge static potential

• Do not touch the connector pins

Power

AN-X requires a DC power input of anywhere from 12 to 24 VDC.

Left to right the pins on the power connector are chassis ground, negative voltage and

positive voltage.

The chassis ground should be connected.

Power consumption is 200 mA @ 12VDC or 100mA @ 24VDC.

The part number for the power connector is Phoenix MSTB 2.5/3-ST-5.08

Package Contents

• AN-X2-ABRIO module

• microSD to SD card adapter

• CD containing software and documentation

• rubber feet for desktop use

Using the MicroSD Card

The AN-X2 microSD card stores configuration data and firmware.

The are no restrictions on the size or speed of the card. The format must be FAT-16 or

FAT-32.

An adapter is provided so you can insert the microSD card in an SD slot in your

computer.

The card must be present while the AN-X2 is running.

WARNING!

Do not remove the card while the AN-X2 is powered on!

If the AN-X2 is inaccessible from Ethernet because of its settings, you can remove the

card and edit the file config.txt. Refer to page 12 for details.

Reinsert the card in the slot at the back of the AN-X2. with the pins facing up.

WARNING!

If you remove the card to edit the configuration file, push the card in

straight or the card might fall inside the case and you will have to

disassemble the AN-X2 to retrieve it .

Hardware Features

The module has:

• two LEDs to indicate the status of the connection to the Ethernet (100 and Link/Act)

• an LED to indicate the module’s internal state and the state of Ethernet

communication (MS or SYS)

• an LED to indicate the state of communications on the Remote I/O network (NS or NET)

• an Ethernet connector

• a power connector

• a 3-pin Phoenix connector to connect to the remote I/O network

A watchdog timer is implemented in the module’s hardware. If the firmware does not

kick the watchdog within the timeout period the watchdog times out and places the

module into a safe fatal failure state.

A jabber inhibit timer is implemented in the module’s hardware. If the network

transmitter is on longer than 150% of the longest network frame time, the transmitter is

forced off and the module is placed into a safe fatal failure state.
