On remote I/O the AN-X module supports:

• Baud rates 57.6. 115.2. and 230.4 Kbaud

• Rack numbers 0 to 76 octal

• Block transfers at all allowable locations

On Ethernet, the AN-X supports up to 16 Ethernet/IP connections. Each Ethernet adapter

and the associated discrete I/O requires one connection. Each analog module requires one

connection. In some cases, a discrete module will require a separate connection, for

example, if desired functionality is available only if the module has its own connection.

The AN-X2-ABRIO-EIPSCN module has a web interface for configuring the module, for

monitoring logs and for performing administrative functions. You can communicate with

the module using any standard web browser such as Internet Explorer.

The module firmware can be selected and updated using the web interface. 

Refer to page 41 for details.

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.

The AN-X emulates a ControlLogix scanning I/O over Ethernet.

All configuration data comes from the AN-X, not from remote I/O. Configuration

options correspond to what’s available in a ControlLogix, not to what is available in

remote I/O. No configuration data gets passed from remote I/O to Ethernet. If your

program dynamically changes configuration data, or if it contains logic to configure a

module, the program will have to be modified to remove or disable that logic.

You may need to make some changes to the control application related to addresses, logic

and timing.

Some behaviour that is set by switches on the remote I/O adapter is set in parameters for

Ethernet modules. For example, hold last state is set on a module-by-module basis when

you scan over Ethernet.

In addition, you may need to make changes because Ethernet does not support

complementary I/O, or standard 32 or complementary 32 addressing.

For example, 32 bit discrete Flex I/O modules require a separate Ethernet connection.

You must communicate with them from remote I/O using block transfers, not as discrete data.

AN-X2-ABRIO-EIPSCN Module Overview

The AN-X2-ABRIO-EIPSCN communications module connects a scanner such as a

PLC-5 on an Allen-Bradley remote I/O network to I/O modules on Ethernet/IP.

As parts become obsolete and remote I/O adapters become unavailable, the

AN-X2-ABRIO-EIPSCN is a solution that lets you retain the original controller, I/O

modules and field wiring and replace remote I/O adapters with Ethernet adapters. The

existing remote I/O scanner talks to the AN-X, which maps discrete and analog I/O on

remote I/O to Ethernet data.

Some behaviour that is set by switches on the remote I/O adapter is set in parameters for

Ethernet modules. For example, hold last state is set on a module-by-module basis when

you scan over Ethernet.

In addition, you may need to make changes because Ethernet does not support

complementary I/O, or standard 32 or complementary 32 addressing.

For example, 32 bit discrete Flex I/O modules require a separate Ethernet connection.

You must communicate with them from remote I/O using block transfers, not as discrete data.

Remote I/O Scanner

This 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

 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

 Works with both ControlLogix or CompactLogix

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

DH+

This 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

 Configures through web browser

 Supports all DH+ baud rates (57.6. 115.2. and 230.4 K baud)

 Support for DH+ to EtherNet/IP PanelViews upgrades on PLC5 or SLC networks

Flex I/O Scanner

This 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 count as a single connection. Each analog module counts as a single connection

The AN-X2-AB-DHRIO Gateway is designed to help customers initiate

a phased migration approach to replacing or upgrading legacy Remote

I/O PLCs, HMI’s, Drives or Flex I/O Adapters. These solutions can be

achieved by selecting the corresponding operation mode during initial

configuration. The AN-X2-AB-DHRIO has a built-in web server that can

display diagnostics data, configuration, upload configuration files, and

set the operation mode.

Note: Now supports DH+ migrations on SLC networks. Some PLC

code change may be required see TN143269-001 DH+ to EIP PV

drives.

 No changes to PLC code required

 Supports up to 4 EtherNet/IP drives

 Configurable with 1/4. 1/2 and full rack addressing

Plus 7 on EtherNet/IP.
