PRODUCT PROFILE
The PowerFlex
®
22-SCM-232 provides an RS-232
DF1 connection for PowerFlex 4 and 40 AC
drives and other DSI-based host devices.
The module provides a means for drive
software tools, such as DriveExplorer
™
and
DriveExecutive
™
, to communicate with drive
products. It also allows various Allen-Bradley
®
controllers, from MicroLogix
™
to ControlLogix
®
,
to control and read/write data to PowerFlex
4 and 40 AC drives.
PRODUCT HIGHLIGHTS
External Mount – The module connects
externally and is powered by the drive.
DSI Routing – Allows DriveExplorer to
connect to a PowerFlex 4 and 40 AC drive
using a 22-SCM-232 serial converter and
then route out over EtherNet/IP, DeviceNet,
or RS-485 to access other PowerFlex 4 and
40 AC drives (1-to-many connection). This
eliminates the need for a separate network
connection and interface.
DriveExplorer Lite Included –
A DriveExplorer Lite CD is included with the
22-SCM-232. DriveExplorer Lite is freeware
and can also be downloaded at:
http://www.ab.com/drives/driveexplorer/
free_download.html
Modbus RTU Master Support –
The module can also be configured to operate
as a Modbus RTU Master. The module converts
both the media (RS-232 to RS-485) and the
protocol (DF1 to Modbus RTU). Any Allen-Bradley
controller capable of originating and
receiving DF1 messages via its front port can
be used to control and read/write data on a
Modbus RTU network:
• MicroLogix 1000 (Series C or later discrete
controllers, and all analog controllers)
• MicroLogix 1200/1500
• SLC 5/03, 5/04, 5/05
• PLC-5
• ControlLogix, CompactLogix
Modbus RTU Pass-Thru Support – The module can also be configured to
operate as a RS-232 (DB-9) to RS-485 (RJ45) serial converter, where Modbus RTU
messages pass-thru both directions in the module.
Flash Upgradeable – The module can be flash updated in the field using
DriveExplorer, DriveExecutive or ControlFLASH to take advantage of new firmware
features as they become available. The module is also the primary connection
mechanism for flashing drives and other peripherals.
ACCESSORIES
Do you have a PC with only a USB connection? Use a USB to Serial adapter, such
as an Allen-Bradley 9300-USBS, to connect to the RS-232 side of the 22-SCM-232.
The adapter is a small, portable unit with no AC power required. It has also been
tested with Allen-Bradley DriveExplorer and DriveExecutive software tools.
Do you want to connect to a drive without having to open the enclosure door?
Use a GracePort
™
interface, such as a P-A20-B3RX (Nema 4/12 interface) or
P-A20-F3RO (Nema 4/12 interface with AC outlet), available from Grace
Engineered Products Inc. (http://www.grace-eng.com).
