Chapter 1 Getting Started
Features The features of the PROFINET adapter include:
• Standard network protocol support – MRP (Media Redundancy Protocol), LLDP (Link Layer
Discovery Protocol), and SNMP (Simple Network Management Protocol).
• Industrial Ethernet switch and network ports that provide connections for EtherNet/IP™
such as star and linear network topologies.
• Physical switches to set a network node address before you apply power to the drive. You
can also disable the switches and use DCP (Discovery and Basic Configuration Protocol), or
adapter parameters to configure the IP address.
• Supports RT (real-time) channel. Does not support IRT (isochronous real-time) channel.
• Compatibility with the following configuration tools to configure the adapter and host drive:
- PowerFlex 22-HIM-A3 or 22-HIM-C2S HIM (Human Interface Module).
- Connected Components Workbench™ software, version 13 or later.
- Third-party PROFINET controlling and monitoring software.
• Status indicators that report the status of the adapter and network communications.
• Parameter-configured 16-bit Datalinks in the I/O to meet application requirements (four
Datalinks to write data from the network to the drive, and four Datalinks to read data to the
network from the drive).
• Supports synchronous messaging and asynchronous parameter access.
• Acyclic messaging support.
• Leader-follower hierarchy that can be configured so that the adapter and drive transmit
data to and from a PROFINET controller on the network.
• Multi-drive mode, which allows up to five drives to share one EtherNet/IP node.
• User-defined fault actions to determine how the adapter and its host drive respond to the
following:
- I/O messaging communication disruptions (Comm Flt Action).
- Controllers in Idle mode (Idle Flt Action).
Understand Parameter
Types
The manual references two types of parameters:
•Device parameters are used to configure the adapter to operate on the network. These
parameters reside on the adapter.
•Host parameters are used to configure the drive, including the Datalink configuration for the
Datalinks used by the adapter. These parameters reside on the drive.
Parameter names are shown in the format device parameter xx [*] or host parameter axxx [*].
The ‘xx’ or ‘xxx’ represents the parameter number and the ‘a’ represents the parameter group. The
* represents the parameter name – for example, device parameter 01 [MultiDrv Sel].
You can view device parameters and host parameters with any of the following drive configuration
tools:
• PowerFlex 22-HIM-A3 or 22-HIM-C2S HIM.
• Connected Components Workbench software — click the tab for the adapter at the bottom
of the window and click the Parameters icon in the toolbar.
Compatible Products At the time of publication, the adapter is compatible with PowerFlex 525 (firmware revision 7.001 or
later) and PowerFlex 523 drives (firmware revision 3.001 or later).

Safety Precautions 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 removed 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 drive using this adapter. Failure to comply may result in injury and/or
equipment damage.
ATTENTION: Risk of equipment damage exists. The adapter contains
electrostatic discharge (ESD) 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, see
Guarding Against Electrostatic Damage,
publication 8000-4.5.2.
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 the adapter.
ATTENTION: Risk of injury or equipment damage exists. Device parameters 22
[Comm Flt Action] and 23 [Idle Flt Action] let you determine the action of the
adapter and drive if I/O communication is disrupted, the controller is idle, or
acyclic messaging for drive control is disrupted. By default, these parameters
fault the drive. You may configure these parameters so that the drive continues to
run, however, precautions should be taken to ensure that the settings of these
parameters do 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 controller in idle state).
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.

Chapter 2
Install the Adapter
This chapter provides instructions to install the PROFINET adapter in a PowerFlex 520-series drive.
Prepare for Installation Before you install the adapter, do the following:
• Read the PROFINET Installation Guidelines.
• Verify that you have the required equipment. See Required Equipment on page 11 for more
information.
Set the Node Address There are three methods to configure the node address of the adapter:
•Node Address Switches — Use these switches when connected to a simple isolated
network (for example, 192.168.1.xxx) that includes other products (that can also set their IP
addresses with switches), does not need to be accessed from outside the network, and you
prefer a simplified node addressing method.
The three rotary switches are read when the drive powers up, and represent three decimal
digits from top to bottom. When set to a valid address (001...254), the adapter uses that
value as the lower octet of its IP address (192.168.1.xxx, where xxx = rotary switch settings),
along with a subnet mask of 255.255.255.0, and a gateway address of 0.0.0.0 when
switches are set to 001, or a gateway address of 192.168.1.1 when switches are set from
002….254. Also, the setting for device parameter 05 [Net Addr Sel] is automatically
ignored.
See Node Address Switch Settings on page 16 for more information.

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, see Guarding
Against Electrostatic Damage, publication 8000-4.5.2.
IMPORTANT The adapter has embedded Ethernet switch technology and network ports
that can connect to a Linear or Device Level Ring (DLR) network in one
subnet.
You cannot use the network ports as two network interface cards that are
connected to two different subnets.
IMPORTANT When using the node address switches, set the network node
address before power is applied because the adapter uses the node
address it detects when it first receives power.

Chapter 2 Install the Adapter
•Adapter Parameters — Use adapter parameters when you want more flexibility in setting
the IP address, or need to communicate outside the control network using a gateway. To
use parameters as the source for the IP address, the node address switches must be set to
a value other than 001…254 or 888, and device parameter 05 [Net Addr Sel] must be set to
1 “Parameters”. Then use the parameters to configure the IP address, subnet mask, and
gateway address of the adapter.
See Use Adapter Parameters on page 26 for more information.
•DCP — This is the default setting for the adapter. Use DCP when you want additional
flexibility and ease-of-use. The IP address, subnet mask, and gateway address for the
adapter is configured by a PROFINET controller with DCP capability. To use DCP as the
source for the IP address, the Node Address switches must be set to a value other than
001…254 or 888, and device parameter 05 [Net Addr Sel] must be set to 2 “DCP”.
Figure 1 - Node Address Switch Settings
You can view diagnostic item number 58 with a PowerFlex 22-HIM-A3 or 22-HIM-C2S HIM, or
Connected Components Workbench software to verify the node address switch settings. See View
Adapter Diagnostic Items on page 65 for more information. Also, you can use device parameter 06
[Net Addr Src], a read-only parameter, to verify the selected setting for device parameter 05 [Net
Addr Sel].
Connect the Adapter to the
Drive
IMPORTANT If parameter values are invalid or the adapter was not reset for the
values to take effect, the node address is established by using DCP.
IMPORTANT Regardless of the method used to set the node address of the adapter,
each node on the PROFINET network must have a unique IP address. To
change a node address, you must set the new value and then remove and
reapply power to (or reset) the drive.
Table 1 - Node Address Switch Settings
Setting Description
001 The adapter uses 192.168.1.1 for the IP address and 0.0.0.0 for the gateway address.
002…254 The adapter uses the node address switch settings for the last octet of the IP address
(192.168.1.xxx). The adapter uses 192.168.1.1 for the gateway address.
888 Resets the adapter to factory default settings. Thereafter, power down the drive, set the switches to a value other than 888, and power up the drive. This procedure must be performed
to accept the new network address.
Any other value
Disables the node address switches and uses device parameter 05 [Net Addr Sel] to select

4. Route the other end of the PROFINET cable from the network through the bottom of the drive
and insert its cable plug into the NET A port on the adapter. See Figure 2 for an example of
wiring to a PROFINET network.
5. To connect to the second drive, attach another PROFINET cable from the NET B port of the
adapter in the first drive to the NET A port of the adapter in the second drive. To connect
additional drives, repeat this daisy chain connection in the same way.
Figure 2 - PROFINET Wiring Example
IMPORTANT The CS1/CS2 terminals on the adapter provide a clean ground for the
communication bus cable shields. You should connect the CS1 or
CS2 terminal to a clean ground or PE ground on the drive.
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 removed before installing or removing an

Use MRP for Ring Network
Topology
A ring network topology is a single-fault tolerant network intended for interconnection of
automation devices. MRP (Media Redundancy Protocol) is a simple and deterministic protocol,
which when enabled in a PROFINET network connected in ring topology, achieves a reconfiguration
time of 200 ms. A maximum of 50 devices can be connected in a ring network topology by using
MRP.
When enabled in ring topology, MRP offers the following advantages.
• Media redundancy.
• Higher communication availability.
• Reduced number of network components.
• Fast network fault detection and reconfiguration.
• Resiliency of a single-fault tolerant network.
• Easy implementation without any additional hardware requirements.
The 25-COMM-PNET2P adapter can only be connected as MRC (Media Redundancy Client) and will
not work as MRM (Media Redundancy Manager). An MRM capable device needs to be present in the
network to achieve the media redundancy. See Figure 3 for a typical connection that has both MRM
and MRC in a ring network.
Figure 3 - Network Connection for an MRP Switch/Controller in a Ring Network
The following settings need to be considered for an MRP capable switch/controller connected in a
ring network.
• Cycle time: 128 ms
• MRM functionality: Enabled
• Ring ports to be defined
