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

TIP: A total of 247 drives can be supported on the RTU Master network
when RS-485 repeaters are installed.
