understanding of the product.
ATTENTION:The drive may contain high voltages that can
cause injury or death. Remove all power from the drive, and
then verify power has been removed before installing or
removing a DeviceNet module. Failure to observe these
precautions could result in severe bodily injury or loss of life.
ATTENTION:Only qualified personnel familiar with the
construction and o peration of this equipment and the hazards
involved should install, adjust, operate, or service this
equipment. Read and un derstand this docum ent in its entirety
before proceeding. Failure to observe this precaution could
result in severe bodily injury or loss of life.
ATTENTION:If the DeviceNet module is transmitting control
I/O to the drive, the drive may fault when you reset the mod ule.
Determine how your drive will respond before resetting a
module. Failure to observe this precaution could result in
bodily injury and/or damage to equipment.
ATTENTION:Comm Flt Action (7) and Idle Flt Action (8) let
you determine the action of the mo du le an d connected drive
if communications are disrupted. By default, these parame ters
fault the drive. You can set these paramete rs so that t he drive
continues to run. Pr eca uti ons s ho uld be taken to ensure that
the settings of these parameters do not create a hazard of
injury or equipment d amage. Failure to observe this p recaution
could resu lt in bodily in jury and/or damage to equipment.
ATTENTION: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 test ing. Failur e to observe this precaution c ould
result in bodily injury and/or damage to equipment.

DeviceNet Communications Module
CHAPTER 1
Introduction
This manual provides information about the DeviceNet module
(MDCOMM-DNET) and using it with MD65 drives. The module is
mounted in the MD65 drive and receives its required power from the
drive and from the DeviceNet network.
This manual is intended for qualified electrical personnel familiar
with installing, programming, and maintaining AC drives and
DeviceNet networks.
1.1 DeviceNet Module Features
The DeviceNet module features the following:
• Switches that ena ble y ou to set a no de ad dress and n etwor k dat a
rate before applying power to the drive. Alternatively, you can
disable the switches and use parameters to configure these
features.
• A jumper that allows you to select between Single- or Multi-Drive
mode of operation. In single mode, the module represents one
single drive on one node. In Multi-Drive mode, the module
represents up to five drives on one node.
• A number of configurati on to ols tha t ca n be used to configure the
module and connected drive. The tools include the Operator
Interface Module (OIM) on the drive, network software such as
RSNetWorx for DeviceNet, or drive-configuration software such
as VS Utilities.
• Status indicators that report the status of the drive
communications, module, and network. They are visible both
when the cover is opened and when it is closed.
Introduction
• I/O, including L ogic Comman d/Reference, that may be co nfigured
for your application using a parameter.
• Explicit and UCMM (Un conne cted Me ssag e Manag er) mess ages
are supported.
• Multiple data exchange methods, including polled, cyclic, and
change of st ate (COS), th at can b e used t o transmi t dat a betwee n
the network and module.
1-1
• User-defined fault actions that determine how the module and
MD65 drive respon d to commun ication disr uptions on th e network
and controllers in idle mode.
• Faulted node recovery is supported. You can configure a device
even when it is faulted on the network if you have a configuration
tool that uses faulted node recovery and have properly set
module node address switches and data rate switches.

module.
2 Verify that the MD65 drive is properly
installed.
3 Commission the module.
Set a unique node address and the
appropriate data rate us in g th e s w itc he s o n
the module . If desired, you can disable the
switches and use parameter settings
instead.
4 Install the module.
Verify that the MD65 drive and DeviceNet
network are not powered. Then, connect
the module to the network using a
DeviceNet cable and to the drive using the

CHAPTER 4
Configuring the
DeviceNet Module
Chapter 4 provides instructions and information for setting the
parameters in the DeviceNet module.
For a list of parameters, refer to Appendix B, DeviceNet Module
Parameters. For definitions of terms in this chapter, refer to the
Glossary.
4.1 Configuration Tools
The DeviceNet module stores parameters and other information in
its own non-volatile memory. Therefore, you must access the
module to view and edi t it s p arameters. Table 4.1 lis t s the tools that
can be used to access the module parameters.

LCD OIM Sect ion 4.2
RSNetWorx for DeviceNet Section 4.3
RSNetWorx for DeviceNet (version 4.018) and RSLinx (version
2.40) were used for examples in this manual. Different versions of
software may differ in appearance and procedures.
Note that explicit messaging can also be used to configure a
DeviceNet module and drive. Refer to Chapter7, Using Explicit
Messaging.

4.2 Using the LCD OIM to Configure the
Module
Use the procedure in figure 4.1 to access the parameters on the
DeviceNet module using the LCD OIM (M/N MD4LCD-PNL,
MD4ALCD, or MD1CC). If you are unfamiliar with the operation of
the LCD OIM, refer to the OIM Quic k Referenc e (D2-350 8) for more
information.

RSNetWorx for DeviceNet is a Rockwell Software application that
can be used to set up Devi ceNet netwo rks and con figure conn ected
devices.
4.3.1 Setting Up RSLinx for RSNetWorx for
DeviceNet
To use RSNetWorx for DeviceNet, you must first set up a driver in
RSLinx. The driver provides a communications link between the
computer and DeviceNet network. See table 4.2 and figure 4.2 for
this procedure.

4.3.2 Going Online with RSNetWorx for DeviceNet
You can view the devices on a DeviceNet network by going online.
A device may appear as an unrecognized device (node 63 in figure
4.3) if RSNetWorx for DeviceNet does not have an Electronic Data
Sheet (EDS) file for it. See table 4.3 for the procedure to view
devices.
