Required Tools and Equipment

Have the following tools and equipment ready:

• medium blade screwdriver

• (2) 1/2 watt terminating resistors (See page 18 for correct size.)

• an adequate length of RIO communication cable (Belden™ 9463) for your

specific application. (See page 18 for maximum cable distances.)

Determining System Power Requirements

Review the power requirements of your system to ensure that the chassis supports

placement of the 1747-ASB module. The adapter consumes 600 mA at 5V dc. For a

detailed list of device load currents, refer to the SLC 500 Fixed Hardware Style

Installation and Operation Manual, publication number 1747-6.21; the SLC 500

Modular Hardware Style User Manual, publication number 1747-UM011, or the

appropriate Technical Data sheet.

1747-ASB Module Overview

The 1747-ASB module is an SLC 500 single-slot, RIO communication link module. It

occupies the first slot (slot 0) of a 1746 remote chassis, where the SLC processor

normally resides.

The 1747-ASB module is an adapter, or slave, on the RIO link, and the master of the

remote chassis and remote expansion chassis in which it is installed. Remote

expansion chassis are optional. The module acts as a gateway between the scanner

and the I/O modules residing in the remote chassis and remote expansion chassis.

It maps the image of the I/O modules in its remote chassis and remote expansion

chassis directly to the SLC or PLC processor image.

Output data is sent from the scanner of either the SLC or PLC local chassis to the

1747-ASB module across the RIO link. This data is automatically transferred to the

output modules across the chassis backplane by the 1747-ASB module. Inputs from

the input modules are collected via the backplane by the 1747-ASB module and

sent back to the scanner across the RIO link. No user programming of the 1747-ASB

module is necessary.

Enable Web Server in User-set IP mode

1. Set the switches to 000 and cycle power to the adapter.

The module LED flashes red and the four-character status display scrolls

the message “Web Server Enabled”.

2. Set the switches to 999 and cycle power to the adapter.

3. In RSLinx software, change the Port Configuration setting to “Manual

IP”, set the desired IP address, and cycle power to the adapter.

4. In your web browser, enter the IP address of the adapter.

The web server home page displays.

Disable Web Server in User-set IP mode

1. Set the switches to 901 and cycle power to the adapter.

The module LED flashes red and the four-character status display scrolls

the message “Web Server Disabled”.

2. Set the switches to 999 and cycle power to the adapter.

3. In RSLinx software, change the Port Configuration setting to “Manual

IP”, set the desired IP address, and cycle power to the adapter.

4. In your web browser, enter the IP address of the adapter.

IMPORTANT If you set the value of the adapter switch to 888 and then power cycle

the module, the following occurs:

• The DHCP Enabled function is enabled (set to True).

• The Ethernet link is negotiated automatically. The Auto Negotiate

function is set to True.

• The web server is enabled. The Disabled Web Server function is

disabled.

• The Ethernet ports are disabled. Both ports are re-enabled once the

switches are returned to their previous value and power is cycled.

Enable or Disable the Web Server

Enable Web Server in Static IP mode

1. Set the switches to 000 and cycle power to the adapter.

The module LED flashes red and the four-character status display scrolls

the message “Web Server Enabled”.

2. Set the switches to the desired IP address and cycle power to the adapter.

3. In your web browser, enter the IP address of the adapter.

The web server home page displays.

Disable Web Server in Static IP mode

1. Set the switches to 901 and cycle power to the adapter.

The module LED flashes red and the four-character status display scrolls

the message “Web Server Disabled”.

2. Set the switches to the desired IP address and cycle power to the adapter.

3. In your web browser, enter the IP address of the adapter.

The web server home page does not display.

The network address switches are set to 999 and DHCP enabled, by default.

You can set the network Internet Protocol (IP) address in the following ways:

• Use the network address switches on the module.

• Use a Dynamic Host Configuration Protocol (DHCP) server, such as

Rockwell Automation BootP/DHCP.

• Retrieve the IP address from nonvolatile memory.

The adapter reads the network address switches first to determine if the

switches are set to a valid number. You set the node address by using the

network address switches. Valid settings range from 001…254.

When the switches are set to a valid number, the adapter’s IP address is

192.168.1.xxx (where xxx represents the number set on the switches).

The adapter’s subnet mask is 255.255.255.0 and the gateway address is set to

0.0.0.0. The adapter does not have a host name assigned, or use any Domain

Name System when using the network address switch settings.

If the switches are set to an invalid number (for example, 000 or a value greater

than 254 excluding 888), the adapter checks to see if DHCP is enabled. Setting

the switches to 888 restores default factory settings.

Module Description

The 1747-AENTR Adapter enables CompactLogix™ and ControlLogix®

processors to control SLC™ I/O modules. It is primarily designed to enable

migration of existing SLC controlled systems to Logix-based systems.

The adapter mainly acts as a gateway between the SLC backplane and

EtherNet/IP and typically replaces an SLC controller in the 1746 rack. On

remote SLC racks, it replaces the 1747-ASB module or the ControlNet® adapters

1747-ACN15 and 1747-ACNR15.

Control of the backplane I/O is accomplished with a CompactLogix or

ControlLogix controller communicating through an EtherNet/IP router in the

Logix backplane, across EtherNet/IP, and into the 1747-AENTR gateway.

As a gateway between the SLC backplane and EtherNet/IP, the 1747-AENTR

module is a CIP™ server (for both Explicit Messaging and I/O) on the Ethernet

port, and an SLC host on the 1746 backplane.
