Dual-port EtherNet/IP™ Adapter
For a Variety of PowerFlex® Drives and Smart Motor Controllers
Overview
The Allen-Bradley® 20-COMM-ER Dual-port EtherNet/IP™ adapter
provides an internal network connection for PowerFlex® 70, 700, 700H,
700S and 7000 AC drives and PowerFlex DC drives as well as SMC™ Flex
and SMC-50 Smart Motor Controllers. The adapter mounts inside the
drive or SMC to save panel space and provides a convenient way to
control, confi gure and collect data over an EtherNet/IP network.
The fi eld-installable adapter supports linear, star and ring topologies
as well as Device Level Ring functionality.
Additional Features
I/O Messaging – I/O messaging is used to transfer time-critical data,
such as data that controls the drive or SMC. The following data can be
sent and received by the adapter:
• Logic Command/Reference
• Logic Status/Feedback
• Datalinks – read and write up to 8 parameters
Explicit Messaging – Explicit messaging involves information that is
not time-critical and is typically triggered by the application (ladder
program in a controller, etc.). The adapter supports the reading/writing of
parameters, etc. in the drive/SMC and to any connected DPI peripheral.
Peer-to-Peer Capability – Allows a PowerFlex drive to operate as a
“master” and communicate with other PowerFlex 70, 700, 700H and 700S
AC drives operating as “followers.” The “master” can send control and
speed reference data along with up to two parameter values.
Advantages
Device Level Ring (DLR) –
DLR functionality helps reduce
confi guration time and provides
fault tolerant connectivity for high
machine availability.
Multiple Confi guration Tool
Options – A variety of tools can be
used to confi gure the adapter and the
connected device. These tools include
the PowerFlex DPI HIM, or confi guration
software such as DriveTools SP Software,
Connected Components Workbench or
Studio 5000™ Logix Designer software
Add on Profi les (AOPs). This adapter
requires v4.05 AOPs.
Password-Protected Web Interface –
Use a web browser such as Microsoft®
Internet Explorer™ to access the
drive/SMC over the Intranet or Internet.
• TCP/IP Confi guration – View TCP/
IP confi guration data and Ethernet
diagnostic information.
• Email Notifi cation – Confi gure email
notifi cation if a specifi c fault or alarm
occurs, if any fault or alarm occurs, or
if the drive/SMC is reset.
• DPI Backplane Browse – View every
DPI device, including the drive and
connected peripherals. Provides
general device information, diagnostics,
events and alarm information.
• Parameter Confi guration – On-line
parameter confi guration for the
SMC-50 and SMC Flex makes set up
fast and convenient.
Flash Upgradeable – The adapter can
be fl ash updated in the fi eld to take
advantage of new fi rmware features as
they become available.
Diagnostics – Built-in diagnostics allow drive or SMC-side
troubleshooting of the network connection using a
PowerFlex DPI HIM, Connected Components Workbench™
or DriveTools™ SP Software. View actual Logic Command/
Reference, Logic Status/Feedback and Datalink data being
transmitted to and from the controller.
User Confi gurable Fault Responses – selects the action
that the adapter and drive/SMC will take for:
• Idle Fault Action – the scanner is idle (controller in
program mode)
• Comm Fault Action – network communications have
become disrupted
Available actions include:
• Fault – the drive/SMC is faulted and stopped
• Stop – the drive/SMC is stopped using the current
deceleration or stopping mode rate and is not faulted
• Zero Data – the adapter zeros the I/O data transmitted
to the drive
• Hold Last – the adapter continues sending the I/O
data prior to the fault and the drive continues in its
present state
• Send Fault Confi guration – the user specifi es the
Logic Command, Reference, and Datalink data that
is sent to the drive, allowing complete fl exibility in
confi guring a fault action

EtherNet/IP – A Single Network for Complete Machine Control
When you select EtherNet/IP for your application, you gain the benefi ts of an open and broadly adopted network with
robust global standards established by ODVA. You can easily integrate PowerFlex drives, SMC Smart Motor Controllers,
I/O and any other EtherNet/IP connected device on a common network. In addition, EtherNet/IP is low cost, high
performance and easy to use compared to a multi-network architecture.

Dual-port EtherNet/IP Adapter Off ers Benefi ts of Device Level Ring Technology
• DLR-based networks reduce confi guration time and costs by minimizing the number of managed switches and
reducing cabling needs
– In most cases, use of the Dual-port EtherNet/IP Adapter eliminates the need for an external switch with the
PowerFlex drives
– Reduces wiring – embedded industrial switch reduces long wire runs
• Users can create a single fault-tolerant DLR network that connects all components at the device level locally. If one
device on the EtherNet/IP network fails, the other devices are able to continue operation
• The fault tolerant connectivity helps provide high machine availability
• Recovery time is fast when a single fault occurs on the network
• DLR is a global ODVA standard, helping to ensure multi-vendor interoperability. Refer to the ODVA website for more
