Prosoft AN-X2-ABRIO-EIPSCN Remote I/O to Ethernet/IP Scanner Module

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.

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.
