AN-X2-AB-SCAN Module Overview
The AN-X2-AB-SCAN communications module connects a ControlLogix PLC or
other device to an Allen-Bradley remote I/O network.
Themodule acts as a scanner on the remote I/O network, readinginputs and writing
outputs.
It supports up to 32 adapters, racknumbers from0 to 76 octal, anycombination of
partial racks and all remote I/O baud rates.
It also supports blocktransfer reads and writes at all possible locations on these racks.
A ControlLogix processorcommunicates with the module usingscheduled
connections over Ethernet,to read inputs fromthe remote I/O networkand write
outputs.
Themodule is supplied with a Windows utility, AnxAbRioScanCfg, for configuring
and monitoringthe remote I/O networkand mappingthe remote I/O data to
ControlLogix scheduled data
The AN-X2-AB-SCAN module also has a web interface for monitoringlogs and
performingadministrative functions.You cancommunicate with the module usingany
standardweb browser suchas Internet Explorer.
Themodule firmware can be selected and updated using the web interface. Refer to
page 63 for details.

Page 2 AN-X2-AB-SCAN December 2013
HardwareFeatures
Themodule has:
two LEDs toindicate thestatus of the connection to the Ethernet
(100 and Link/Act)
LEDs to indicate the module sinternal state (MS) and the state of
communication (NS). In previous versions ofthe hardware, these
LEDs were labeledSYS and NET.
Important! In version 4.2 and above of the firmware, there aretwo
possible behaviors ofthe MS and NS LEDs. Refer to page 65 for
details.
an Ethernet connector
a power connector
a 3-pin Phoenix connector to connect to the remote I/O network
A watchdogtimer is implemented in the module s hardware. If the
firmware does not kickthe watchdogwithin thetimeout period the
watchdogtimes out and places the module into a safefatal failure state.
A jabber inhibit timer is implemented in the module shardware. If the
networktransmitter is on longer than 150% of the longest network
frame time, the transmitteris forced off and the module is placed into a
safe fatal failure state.

Using the MicroSD Card
The AN-X microSD card stores configurationdata andfirmware.
Theare no restrictions on the size or speed of the card.The format must be FAT-16 or
FAT-32.
An adapter is providedso you can insert the microSD card in an SD slot in your
computer.
Thecard must be present while the AN-X is running.
WARNING! Do not remove the card while the AN-X is powered on!
If the AN-X is inaccessible fromEthernet because of its settings, you can remove the
card and edit the file config.txt. Referto page 13 for details.
Reinsert the card in the slot at the backof the AN-X, with the pins facingup.
WARNING! Ifyou 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-X to retrieve it .
AN-X Modes ofOperation
There aretwo AN-X modes of operation:
Maintenance mode. The AN-X runs the maintenance firmware at startup. It
performs diagnostics (memorytests, etc), copies anychanges fromthe
microSD card. If there are no errors, it starts the AN-X in productionmode.
Production mode. This is the normal runtimemode of operation.

Installation
Prevent ElectrostaticDischarge
Themodule is sensitive to electrostatic discharge.
WARNING! Electrostatic discharge candamage integrated circuits or
semiconductors. Follow these guidelines whenyou handle the module:
Touch a grounded object todischarge staticpotential
Do not touch the connector pins
Power
AN-X requires a DC power input of anywhere from12 to 24 VDC.
Left to right the pins on thepower connector are chassis ground, negative voltageand
positive voltage.
Thechassis ground should be connected.
Power consumption is 200 mA @ 12VDC or 100mA @ 24VDC.
Thepart number for the power connector is Phoenix MSTB 2.5/3-ST-5.08
Contact us if you need a suitable wall adapter.
Cabling and Termination
Follow Allen-Bradleycablingrecommendations for remote I/O. Refer to Approved
Vendor List for DH, DH+, DH-485, and Remote I/O Cables, publication ICCG-2.2,
February1996.
On the AN-X module, the connections should be line 1, shield, line 2.

Page 6 AN-X2-AB-SCAN December 2013
Line 1 on the AN-X is closest to the power connector.
Checkthe wiringto ensure that line 1 on the AN-X is connected to line 1 on the PLC,
and so on.
Terminate bothends of a remote I/O networkbyusingexternal resistors attached to
the physical ends of thenetwork. There should be two and onlytwo terminators on the
network.
Use 82 ohmresistors if thenetworkoperates at 230.4 kbps or if the networkoperates
at 57.6kbps or 115.2 kbps and none of the devices in the table below are present. The
maximumnumber of physical devices on the network is 32.
Use 150 ohmresistors if the networkcontains anyof the devices inthe tablebelow, or
if the networkoperates at 57.6 kbps or 115.2 kbps and you do not require thenetwork
to support more than 16 physical devices.

Ethernet Cabling
AN-X has a standard RJ-45 connector for connectingto Ethernet.

AN-X2-AB-SCAN Page 7
Ifyou are connecting to the AN-X through a router or switch, use a standard Ethernet
cable.
Ifyou are connectingdirectlybetween a computer and AN-X, use a crossover cable.
TIP Dependingon your Ethernet hardware, a crossover cable maynot be
required.
SoftwareInstallation
You must uninstall anyprevious version of the software before you can install a new
version. Use the WindowsControl Panel Addand Remove Programs or Programs and
Features to remove the old version.
Run the program AnxAbRioSetup.msi in the AB\RIO folder to install the components
for the AN-X2-AB-SCAN

CE Installations
Ifyou are installingthe AN-X in a location which requires CE, install the following
ferrites or their equivalents on the cables:
Steward 28A2024-0A2 on Ethernet cable close to module, one loop
Steward 28A2024-0A2 on power cable

Ethernet Configuration
The AN-X2-AB-SCAN module connects a device suchas a ControlLogix processor
on Ethernetto scan an Allen-Bradleyremote I/O network.
Before you can use the AN-X2-AB-SCAN, you must configure its networkproperties
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 areshippedwith the link-local address 169.254.42.84.
Unless you have control of the DHCP server, in most applications you will assignthe
AN-X a static IP address. Otherwise the DHCP server mayassign a different IP
address each time AN-X powers up, and anysoftware that accesses the AN-X module
would have to be reconfigured.
Ifyou are usingmultiple AN-X modules, connect and configure oneat a time, since
initially theywill all be setto the same link-local IP address.
IMPORTANT! Ifyou are connectingAN-X to an existingEthernet network, consult the
networkadministrator to obtain information about how you should
configure AN-X or to obtain a static IP address for AN-X.
You configure the Ethernetproperties usingthe web interface.
Start a web browser and enter the address 169.254.42.84
TIP The AN-X must be on the same subnet as the computer to use the
link-local IP address. It cannot be connected through a router.
Select Administration/AN-X Configuration.

AN-X2-AB-SCAN Page 11
The AN-X2 Configuration page appears.
At the top, the screenshows the serial number and MAC address of the AN-X being
configured.

Page 12 AN-X2-AB-SCAN December 2013
Checkeither DHCP or Static.
DHCP
If the AN-X finds a DHCP server onthe network, it obtains an IP address and other
networkparameters (netmaskand default gateway) from the DHCP server.
To find the address assigned, you have to lookat the DHCP server.
When you submit the changes, if the AN-X does notfind a DHCP server,it reverts to
the default linklocal address 169.254.42.84 and repeatedlyflashes the MS LED 3
times red followed bya pause.
Static IP Address
Ifyou select static IP address, enter:
the IP address forthe AN-X.
the netmaskfor the AN-X
the default gatewayfor your network.
You must enter a valid default gatewayaddress even if there is no device atthe
gatewayaddress on the network.
Hostname
Enter a Hostname for the AN-X. This name is used internallybyAN-X and maybe
used to identifythe AN-X if you have a DNS server onyour network. Thename can
be from1 to 30 characters long
Firmware
Selectthe firmware the AN-X is to load fromthe list provided. AN-X builds the list
fromthe firmware files on the microSD card that are compatible withthe AN-X
hardware.
Submitting the Configuration
Once you have entered all required parameters, clickSUBMIT to write the
configuration to the file config.txt on the microSD card. The changes do nottake
effect until theAN-X restarts.
Thefollowingpage appears when you clickSUBMIT.
