Features
The ControlNet adapter features the following:
•The adapter is normally installed in a PowerFlex 40 or PowerFlex 400 drive. It can also be used in a DSI External Comms Kit (22-XCOMM-DC-BASE).
•A jumper lets you select between Single or Multi-Drive mode of operation. In Single mode (default), the adapter represents a single drive on one node. In Multi-Drive mode, the adapter represents up to 5 drives on one node.
•A number of configuration tools can be used to configure the adapter and connected drive. The tools include an external PowerFlex 4-Class HIM (22-HIM-*) or drive-configuration software such as DriveExplorer (version 3.01 or higher) or DriveExecutive (version 3.01 or higher).
•Status indicators report the status of drive communications, the adapter, and network.
•Supports I/O, including Logic Command/Reference, for all drives connected in Single or Multi-Drive mode.
•The following table shows the various controllers that can be used with the 22-COMM-C adapter and whether they support explicit messaging (parameter read/write, etc.) on a ControlNet network:

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 
power from the PowerFlex drive, and then verify power has been discharged before installing or removing the 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 the 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.
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. Parameters 08 - [Comm Flt Action] and 09 - [Idle Flt Action] let you determine the 
action of the adapter and connected PowerFlex drive if communications
are disrupted. By default, these parameters fault the drive. You can set these parameters so that the drive continues to run. 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 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. 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.

Preparing for an Installation
Before installing the adapter, verify that you have all required equipment. Refer to Chapter 1, Getting Started.
Setting Operating Mode and Node Address Switches
Before installing the adapter, you must set its Operating Mode Jumper for Single or Multi-Drive operation, and its Node Address Switches to a unique ControlNet node address.
Important: New settings are recognized only when power is applied to the adapter, or the adapter is reset. If you change a setting, cycle power or reset the adapter to invoke the change.
|
|
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. |
|
|
|
2-2 Installing the Adapter
1.Set the adapter Operating Mode Jumper (J7) for Single (1x) or Multi-Drive (5x) operation (see Figure 2.1 and setting descriptions below). For complete details on Multi-Drive mode operation, see Chapter 7, Using Multi-Drive Mode.

|
|
2.Set the adapter node address by rotating the Node Address Switches to the desired value for each digit.
Important: Each node on the network must have a unique address. The node address must be set before power is applied because the adapter uses the node address it detects when it first receives power. To change a node address, you must set the new value. Then remove and reapply power to the adapter, or reset the adapter.

will use the setting of Parameter 02 - [CN Addr Cfg] for the |
|
node address. Refer to Setting the Node Address on page 3-3. |
The node address switch settings can be verified using a PowerFlex 4-Class HIM, DriveExplorer, or DriveExecutive to view Diagnostic Item number 28 (listed on page 8-5 or page 8-6).

Setting the Node Address
If the Node Address Switches on the adapter are set to a node address of “00,” the value of Parameter 02 - [CN Addr Cfg] determines the ControlNet node address.
1.Set the value of Parameter 02 - [CN Addr Cfg] to a unique node address.

2. Reset the adapter (see Resetting the Adapter on Page 3-6).
Setting the I/O Configuration
The I/O configuration determines the number of drives that will be represented on the network as one node by the adapter. If the Operating Mode Jumper (J7 in Figure 2.1) is set to the “1x” (Single mode) default position, only one drive is represented by the adapter and Parameter 12 - [DSI I/O Cfg] has no effect. If the Operating Mode Jumper is set to the “5x” (Multi-Drive) position, up to five drives can be represented as one node by the adapter.
1.Set the value in Parameter 12 - [DSI I/O Cfg].

3-4 Configuring the Adapter
4-Class drives that are daisy-chained to the RJ45 (RS-485) port on Drive 0. When the adapter is externally mounted in a DSI External Comms Kit, Drives 0 through 4 are daisy-chained to the RJ45 (RS-485) port on the Comms Kit. Refer to Chapter 7, Using Multi-Drive Mode for more information.
2.If a drive is enabled, configure the parameters in the drive to accept the Logic Command and Reference from the adapter. For example, set a PowerFlex 40 drive’s parameter P036 - [Start Source] and parameter P038 - [Speed Reference] both to “5” (Comm Port). When using the adapter in Multi-Drive mode, each daisy-chained drive requires that additional parameters be set. See Configuring the RS-485 Network on page 7-7 for these parameters and their settings.
3.Reset the adapter (see Resetting the Adapter on page 3-6).
Setting a Fault Action
By default, when communications are disrupted (for example, a cable is disconnected) or the controller is in program mode, the drive responds by faulting if it is using I/O from the network. You can configure a different response to communication disruptions using Parameter 08 - [Comm Flt Action] and a different response to a controller in program mode using Parameter 09 - [Idle Flt Action].
|
! |
ATTENTION: Risk of injury or equipment damage exists. |
|
Parameters 08 - [Comm Flt Action] and 09 - [Idle Flt Action] let you |
|
|
determine the action of the adapter and connected drive if |
|
|
|
communications are disrupted or the controller is in program mode. By |
|
|
default, these parameters fault the drive. You can set these parameters |
|
|
so that the drive continues to run. Some ControlNet scanners may |
|
|
operate differently when a controller is in program mode which could |
|
|
limit the Idle Fault Action’s operating states. 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 faulted controller). |
