PRODUCT PROFILE
The PowerFlex
®
DSI ControlNet adapter provides
redundant coaxial ControlNet connections for
PowerFlex 40 or PowerFlex 400 drives. The adapter
provides a means to control, configure, and collect
data over a ControlNet network. It can also be used
with other Allen-Bradley products that support a DSI
adapter, such as the DSI External Communications
Kit (22-XCOMM-DC-BASE), which enables PowerFlex
4 drives to connect to a ControlNet network.
PRODUCT HIGHLIGHTS
Internal Mount – The adapter mounts internal
to the drive to save panel space and is field
installable. PowerFlex 40 B frame drives require
an additional front cover 22B-CCB, PowerFlex 40
C frame drives require 22B-CCC, and PowerFlex
400 C frame drives require 22C-CCC.
Configuration – The adapter has rotary switches
for setting the node address and a jumper for
configuring Single or Multi-Drive operating modes.
Multiple Configuration Tool Options – A
number of configuration tools can be used to
configure the adapter and the connected drive.
These tools include the PowerFlex DSI HIM or
drive-configuration software such as
DriveExplorer
™
or DriveExecutive
™
.
Single/Multi-Drive Operation –
The adapter can be used in two modes:
• Single - 1 network node consists of 1 drive.
• Multi-Drive - 1 network node can contain up
to 5 drives. In this cost-saving configuration,
the 22-COMM-C adapter is installed in a
PowerFlex 40 or 400 drive and up to four
additional PowerFlex 4, 40 or 400 drives can
be connected over their built-in RS-485 ports.
Each drive can be individually controlled,
configured, and monitored through the single
ControlNet connection. The adapter can also
be installed in a DSI External Communications
Kit using this operation mode to communicate
with up to 5 PowerFlex 4-Class drives.
I/O Messaging – I/O messaging is used to transfer
time-critical data, such as data that controls the
drive. The following data can be sent and received
by the adapter:
• Logic Status/Speed Feedback
• Logic Command/Speed Reference
Explicit Messaging – Explicit messaging involves
non time-critical information that is typically
triggered by the application (ladder program in a
controller, etc.). The adapter supports:
• Reading/writing of drive parameters
• Reading/writing of adapter parameters
User Configurable Fault Responses – Selects the action that the adapter and drive will
take for the following two conditions:
• 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 is faulted and stopped.
• Stop - The drive is stopped using the current deceleration 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 Configuration - The user specifies the Logic Command and Speed Reference
data that is sent to the drive, allowing complete flexibility in configuring a fault action.
Diagnostics – Built-in diagnostics allow drive-side troubleshooting of the network
connection using a PowerFlex DSI HIM, DriveExplorer or DriveExecutive. View actual
Logic Status/Speed Feedback and Logic Command/Speed Reference data being transmitted
to and from the controller.
Flash Upgradeable – The adapter can be flash updated in the field using DriveExplorer,
DriveExecutive or ControlFLASH to take full advantage of new firmware features as they
become available.
