The RIO-ADPT communications module connects a ControlLogix PLC or other device 

to an Allen-Bradley remote I/O network.

As an adapter, the module:

· has one remote I/O channel

· emulates one or more racks

· supports all remote I/O baud rates: 57.6, 115.2, 230.4 kbaud

· supports rack numbers from 0 to 76 octal

· supports all combinations of partial racks

· supports block transfers at all possible locations

· monitors discrete I/O and block transfer reads and writes on the same remote 

I/O network

· updates all I/O via scheduled connections

The AN-X2-AB-DHRIO module is supplied with a Windows utility, AnxAbRioCfgAdpt, 

for configuring and monitoring the remote I/O network and mapping the remote I/O data 

to ControlLogix scheduled data.

The AN-X2-AB-DHRIO communicates with the ControlLogix processor using scheduled 

connections over Ethernet. Remote I/O data is mapped into the scheduled input and 

output data by the configuration program.

On monitored racks, a ControlLogix processor reads remote I/O inputs and outputs, and 

data from block transfer reads and writes on the remote I/O network. All remote I/O data 

is mapped to scheduled inputs in the ControlLogix.

On emulated (active) racks, a ControlLogix processor writes remote I/O inputs and block 

transfer read data and reads remote I/O outputs and block transfer write data.

The AN-X2-AB-DHRIO module has a web interface for monitoring logs and 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 

57 for details

The module has:

• two LEDs to indicate the status of the connection to the Ethernet (100 and 

Link/Act)

• a LED to indicate the module’s internal state and the state of communication with 

the ControlLogix (SYS)

• a LED to indicate the state of communications on the Remote I/O network (NET)

• an Ethernet connector

• a power connector

• a 3-pin Phoenix connector to connect to the remote I/O network

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.

Package Contents

• CD containing software and documentation

• rubber feet for desktop use

Identifying the AN-X2 versus the Original AN-X

The label on the bottom toward the front says AN-X2.

There is a slot at the back for the microSD card.

When initially powered up:

· AN-X2 railroads (alternates) SYS and NET LEDs green as it starts up

· without the Ethernet cable attached, the Ethernet 10/100 (upper) LED is on for ANX2 (both Ethernet LEDs are off for the original AN-X)

Differences from the Original AN-X

AN-X2 modules have a microSD card for storage of firmware and configuration data.

You no longer need AnxInit; everything can be done from the web interface or by editing 

files on the microSD card.

Operation is simplified, there are production and maintenance modes only.

The AN-X2 requires firmware version 4 and above.
