Safety Precautions
Please read the following safety precautions carefully.
ATTENTION: Risk of injury or death exists. The PowerFlex
drive may contain high voltages that can cause injury or death.
!
Remove all power from the PowerFlex drive, and then verify
power has been discharged before installing or removing an
adapter.
ATTENTION: Risk of injury or equipment damage exists. Only
personnel familiar with drive and power products and the
!
associated machinery should plan or implement the installation,
start up, configuration, and subsequent maintenance of the
product using an adapter. Failure to comply may result in injury
and/or equipment damage.
ATTENTION: Risk of equipment damage exists. The adapter
contains ESD (Electrostatic Discharge) sensitive parts that can be
!
damaged if you do not follow ESD control procedures. Static
control precautions are required when handling the adapter. If
you are unfamiliar with static control procedures, refer to
Guarding Against Electrostatic Damage (publication
8000-4.5.2).
20-COMM-M Modbus/TCP Adapter User Manual
Publication 20COMM-UM014C-EN-P
1-4 Getting Started
ATTENTION: Risk of injury or equipment damage exists. If
the adapter is transmitting control I/O to the drive, the drive may
!
fault when you reset the adapter. Determine how your drive will
respond before resetting an adapter.
ATTENTION: Risk of injury or equipment damage exists.
Parameter 23 - [Comm Flt Action] lets you determine the
!
action of the adapter and connected drive if communications are
disrupted. By default, this parameter faults the drive. You can set
this parameter so that the drive continues to run. Precautions
should be taken to ensure that the setting of this parameter does
not create a risk of injury or equipment damage. When
commissioning the drive, verify that your system responds
correctly to various situations (for example, a disconnected cable
or a faulted controller).
ATTENTION: Risk of injury or equipment damage exists.
When a system is configured for the first time, there may be
!
unintended or incorrect machine motion. Disconnect the motor
from the machine or process during initial system testing.
ATTENTION: Risk of injury or equipment damage exists.
Parameter 19 - [Msg I/O Timer] lets you determine how long it
!
will take the adapter to detect network communication losses. By
default, this parameter sets the timeout to five seconds. You can
set it so that the duration is shorter, longer, or disabled. When set
to disabled, this also disables Parameter 23 - [Comm Flt
Action]. Therefore, a communications fault action will be
ignored. Take precautions to ensure that the setting does not
create a risk of injury or equipment damage. When
commissioning the drive, verify that your system responds
correctly to various situations (for example, a disconnected
cable).
ATTENTION: Risk of injury or equipment damage exists. The
examples in this publication are intended solely for purposes of
!
example. There are many variables and requirements with any
application. Rockwell Automation, Inc. does not assume
responsibility or liability (to include intellectual property
liability) for actual use of the examples shown in this publication.
ATTENTION: For security reasons, it is recommended to
isolate the Modbus/TCP control network from the
!
enterprise-wide Ethernet network. This can be accomplished by:
20-COMM-M Modbus/TCP Adapter User Manual
Publication 20COMM-UM014C-EN-P
• Making the Modbus/TCP control network a stand-alone
network.
• Placing a firewall between the Modbus/TCP control network
and the enterprise-wide Ethernet network.

Configuring/Verifying Key Drive Parameters
The PowerFlex 7-Class drive can be separately configured for the control
and Reference functions in various combinations. For example, you could
set the drive to have its control come from a peripheral or terminal block
with the Reference coming from the network. Or you could set the drive to
have its control come from the network with the Reference coming from
another peripheral or terminal block. Or you could set the drive to have
both its control and Reference come from the network.
The following steps in this section assume that the drive will receive the
Logic Command and Reference from the network.
1. Use drive Parameter 090 - [Speed Ref A Sel] to set the drive speed
Reference to “22” (DPI Port 5).
2. If hard-wired discrete digital inputs are not used to control the drive,
verify that unused digital input drive Parameters 361 - [Dig In1 Sel] and
362 - [Dig In2 Sel] are set to “0” (Not Used).
3. Verify that drive Parameter 213 - [Speed Ref Source] is reporting that
the source of the Reference to the drive is “22” (DPI Port 5). This
ensures that any Reference commanded from the network can be
monitored by using drive Parameter 002 - [Commanded Speed]. If a
problem occurs, this verification step provides the diagnostic capability
to determine whether the drive/adapter or the network is the cause.
Commissioning the Adapter
To commission the adapter, you must set a unique IP address on the
network. (Refer to the Glossary
installing the adapter and applying power, you can set the IP address by
using a BOOTP server or by setting adapter parameters. (See Setting the IP
Address, Subnet Mask, and Gateway Address on page 3-6 for details).
By default, the adapter is configured so that you must set the IP address
using a BOOTP server. To set the IP address using adapter parameters, you
must disable the BOOTP feature. See Disabling the BOOTP Feature
page 3-6 for details.
Important:New settings for some adapter parameters (for example,
Parameters 04 - [IP Addr Cfg 1] through 07 - [IP Addr Cfg
4]) are recognized only when power is applied to the adapter or
it is reset. After you change parameter settings, cycle power or
reset the adapter.

3-8 Configuring the Adapter
Setting the Data Rate
By default, the adapter is set to autodetect, so it automatically detects the
data rate and duplex setting used on the network. If you need to set a
specific data rate and duplex setting, the value of Parameter 16 - [EN Rate
Cfg] determines the Ethernet data rate and duplex setting that the adapter
will use to communicate. For definitions of data rate and duplex, refer to the
Glossary
1. Set the value of Parameter 16 - [EN Rate Cfg] to the data rate at which

Setting the I/O Configuration
2. Reset the adapter (see Resetting the Adapter on page 3-12).
The I/O configuration determines the data that is sent to and from the drive.
Logic Command/Status, Reference/Feedback, and Datalinks may be
enabled or disabled. A “1” enables the I/O. A “0” disables the I/O.
1. Set the bits in Parameter 24 - [DPI I/O Cfg].

Bit 0 is the right-most bit. In Figure 3.10, it is highlighted and equals “1.”
2. If Logic Command/Reference is enabled, configure the parameters in
the drive to accept the Logic Command and Reference from the adapter.
For example, set Parameter 90 - [Speed Ref A Sel] in a PowerFlex 70 or
700 drive to “22” (DPI Port 5) so that the drive uses the Reference from
the adapter. Also, verify that the mask parameters (for example,
Parameter 276 - [Logic Mask]) in the drive are configured to receive the
desired logic from the adapter. Refer to the documentation for your
drive for details.
