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 40 and PowerFlex 400 drives on an RTU Master
network must have an open internal Port 1. Thus, a
22-COMM-* adapter cannot be connected to this port via the
Internal Interface ribbon cable.
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.
Network Wiring
See Network Wiring on page 3-8 for information on wiring an RTU Master
serial multi-drop network.
Establishing Communication
Establish communication between the drive connected to the 1203-USB
converter and the computer.
Important: When using DriveExplorer software to connect to drives on an
RTU Master network, use only DriveExplorer Full software
because DriveExplorer Lite software does not support
multi-drive connectivity.
Configuring the Drive Parameters
See Configuring the Drive Parameters on page 3-10 for information to
configure the drive parameters.
TIP: A total of 247 drives can be supported on the RTU Master network
when RS-485 repeaters are installed.
