Rockwell Automation 22-COMM-B PowerFlex BACnet MS/TP Adapter - Manual (Page 9)

Chapter

Getting Started
The adapter is intended for installation into a PowerFlex 40 or
PowerFlex 400 drive and is used for network communication. The
adapter can also be installed in a DSI External Comms Kit
(22-XCOMM-DC-BASE). This kit enables PowerFlex 4 and PowerFlex
4M drives, which cannot accommodate an internally-mounted adapter,
to connect to a BACnet MS/TP network. NOTE: The 22-COMM-B
adapter must have firmware version 1.003 (or later) to be compatible
with the PowerFlex 4M drive.
