Specifications

The PowerFlex
®
22-COMM-B adapter provides
an internal BACnet MS/TP connection to
PowerFlex 40 and 400 drives. It can also be
installed in a DSI External Communications
Kit for use with PowerFlex 4 drives. The
adapter provides a means to control, configure,
and collect data over a BACnet MS/TP network.
PRODUCT HIGHLIGHTS
Installation – The adapter mounts internal
to PowerFlex 40 and 400 drives to save
valuable panel space, and is field installable.
If an external connection is needed or when
using a PowerFlex 4 drive, the adapter can
also be installed in a DSI External
Communications Kit (22-XCOMM-DC-BASE).
Configuration Switches – The adapter has
configuration switches for setting the MAC
address (addressable up to node 127), and
enabling/disabling the termination and
bias resistors.
Supported Data Rates – The adapter can
“autoband” out-of-the-box or be set to one
of four selectable baud rates (9600, 19200,
38400 or 76800 bps), and can be configured
using a parameter.
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
™
.
DSI Routing – Allows DriveExplorer to connect
to a PowerFlex drive using a 22-SCM-232 or
1203-USB converter and then route over
BACnet MS/TP to access other Allen-Bradley
®
drives. This eliminates the need for a separate
network connection and interface.
BACnet Objects – Unlike other PowerFlex
drive communication adapters, BACnet
MS/TP adapters use network objects to view
logic status, speed feedback and monitor
parameter values, and to send logic control,
speed reference and change parameter
values. The following objects are supported
by the adapter:
• Analog Input (AI)
• Analog Output (AO)
• Analog Value (AV)
• Binary Input (BI)
• Binary Output (BO)
• Binary Value (BV)
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, Reference,
and Datalink 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 Command/Speed Reference and Logic Status/Speed Feedback 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 advantage of new firmware
features as they become available.
