Chapter 1
About the SLC 500 EtherNet/IP Adapter
Overview This chapter provides an introduction to the features and functionalities of the
1747-AENTR SLC™ 500 EtherNet/IP Adapter. It includes the following sections.
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.
Connections can be made to support 1746 and 1747 analog, digital, and
specialty I/O modules installed in the backplane.
For the complete list of supported I/O modules, see the table, List of I/O
Modules Supported by the 1747-AENTR Adapter on page 27.

Chapter 1 About the SLC 500 EtherNet/IP Adapter
Use of the Common
Industrial Protocol (CIP)
The adapter uses the Common Industrial Protocol (CIP), the application layer
protocol specified for EtherNet/IP, the Ethernet Industrial Protocol. It is a
message-based protocol that implements a relative path to send a message
from the producing device in a system to the consuming devices.
The producing device contains the path information that steers the message
along the proper route to reach its consumers. Since the producing device
holds this information, other devices along the path simply pass this
information; they do not store it.
This has the following significant benefits:
• You do not need to configure routing tables in the bridging modules,
which greatly simplifies maintenance and module replacement.
• You maintain full control over the route taken by each message, which
enables you to select alternative paths for the same end device.
Understand the Producer/
Consumer Model
The CIP producer and consumer networking model replaces the old source
and destination (master and slave) model. The producer and consumer model
reduces network traffic and increases speed of transmission. In traditional I/O
systems, controllers poll input modules to obtain their input status. In the CIP
system, input modules are not polled by a controller. Instead, they produce
(multicast or unicast) their data periodically or at a cyclic rate.
Unicast is the default for version 20 with multicast as a selectable option. The
frequency of update depends upon the options chosen during configuration
and where on the network the input module resides. The input module,
therefore, is a producer of input data, and the controller is a consumer of the
data.
The controller also produces data for other controllers to consume. The
produced and consumed data is accessible by multiple controllers and other
devices over the EtherNet/IP network. This data exchange conforms to the
producer and consumer model.
Support of Direct
Connections
The EtherNet/IP adapter only supports direct connections. A direct connection
is a real-time data transfer link between a Logix controller and a 1746/1747 I/O
module through the 1747-AENTR adapter. Direct I/O connections occur at a
cyclic rate specified by the RPI during configuration.

Chapter 2
Install Your Adapter
This chapter describes how to install the 1747-AENTR adapter and connect it to
the EtherNet/IP network.
The following table lists where to find specific information.
Set the Network Address
Switches
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.

Chapter 2 Install Your Adapter
DHCP Enabled and Not Enabled
See the chapter, Configure the Adapter for Your EtherNet/IP Network on
page 21, for information on how to use your BootP/DHCP utility to configure
your adapter for the network.
Enable or Disable the Web Server
With firmware revision 2.003 or later, the web server feature is disabled by
default. Use the network address switches to enable or disable the web server
for your application.
The following section describes how to enable or disable the web server based
on the IP address mode that is used.
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.
DHCP Enabled and Not Enabled
If DHCP is Then the Adapter
Enabled
Asks for an address from a DHCP server. The DHCP server also assigns other Transport Control
Protocol (TCP) parameters.
The 1747-AENTR factory default is DHCP enabled. When you apply power, the module sends a
message containing its hardware address to any DHCP server on the network. The server(s)
replies by sending a message with an appropriate IP address for the adapter. The adapter
responds by acknowledging to a server that it will use the offered IP address.
Not enabled
Uses the IP address (along with other TCP configurable parameters) stored in nonvolatile
memory.
When the IP address assigned to the module, as indicated in the four-character dot-matrix
status display, is changed through the DHCP configuration utility, the DHCP is disabled.
When power is cycled to the device, it uses the new configuration and implements the new IP
address.
Value Description
000 Enables the web server. Cycle power to the adapter for the setting to take effect. When you apply power, the module LED
flashes red and the four-character status display scrolls the message “Web Server Enabled”.
901 Disables the web server. Cycle power to the adapter for the setting to take effect. When you apply power, the module LED
flashes red and the four-character status display scrolls the message “Web Server Disabled”.
IMPORTANT If you set the value of the switch to 901 and then cycle power to the
adapter, the following occurs:

Determine Power
Requirements
The Ethernet adapter requires 5V DC with current consumption of 470 mA.
The power is supplied through backplane from SLC power supply. Remember
to consider this requirement when planning your system configuration.
Install the Adapter Module
in the Chassis
After you set the appropriate switch assemblies for your adapter module,
follow these procedures for installation.
See the Industrial Controller Wiring and Grounding Guidelines publication
1770-4.1 for proper grounding and wiring methods to use when installing your
module.
1. Remove power from the I/O chassis before inserting (or removing) the
module.
2. Align the circuit board with the chassis card guide in the left slot.
3. Install the module in slot 0 of the chassis by aligning the circuit board
with the chassis card guide.
The 1747-AENTR module must be installed only in slot 0 (leftmost slot)of
the chassis.
