Rockwell Automation 20-COMM-Q ControlNet Adapter - Manual (Page 13)

20-COMM-C/Q ControlNet Adapter User Manual
Publication 20COMM-UM003F-EN-P
Chapter 1
Getting Started
The adapter is intended for installation into a PowerFlex 7-Class drive and
is used for network communication. The 20-COMM-C Series B coax
adapter, firmware 2.xxx or later, or 20-COMM-Q Series A fiber adapter,
firmware 2.xxx or later, can also be installed in an External DPI Comms Kit
(20-XCOMM-DC-BASE).
For PowerFlex 750-Series drives, we recommend using the 20-750-CNETC
Coaxial ControlNet option module instead of the 20-COMM-C adapter.
However, this manual does include information on using the 20-COMM-C
or 20-COMM-Q adapter with PowerFlex 750-Series drives—but there are
operating limitations. For details, see
Compatible Products on page 1-3 .
