Updating the Firmware
Connected Components Workbench is not intended to be used as a firmware
update tool. The recommended tool to use is ControlFLASH software,
which is downloaded automatically when the respective firmware revision
file is downloaded from the Allen-Bradley updates website to your
DriveExplorer, DriveExecutive, or HyperTerminal software can also be
used to perform firmware updates on the 1203-USB converter and products
that implement DPI or DSI, such as PowerFlex 7-Class drives and
peripherals, or PowerFlex 4-Class peripherals. When using one of these
tools to update the firmware, see the respective appendix in this manual for
Important:PowerFlex 400 drives can only be updated using a
AK-U9-FLSH1 flash kit. PowerFlex 4, 40, and 40P drives
cannot be updated. Only PowerFlex 4M drives can be updated
using the 1203-USB converter.
Important:DriveExplorer or DriveExecutive software cannot be used to
update products that support SCANport.
Using RTU Master Mode for
a Serial Multi-drop Network
With the converter in RTU Master mode, you can monitor, configure, and
control up to 32 DSI drives.
Important:All PowerFlex 4-Class drives on an RTU Master network must
have an open internal Port 1. Thus, a 22-COMM-* adapter
cannot be connected to this port through the Internal Interface
Important:All PowerFlex 520-Series drives on an RTU Master network
must not have a DSI communication option installed or
connected (only the 1203-USB converter can be connected).
When a drive faults in an RTU Master network, all other drives remain
operational and unaffected.
See Figure 3.1
for a network wiring example to wire an RTU Master network.
