Rockwell Automation 22-COMM-D DeviceNet Adapter - Manual (Page 77)

Using Multi-Drive Mode 7-5
The following parameters must be set in the daisy-chained drives:
Note that the RS-485 network is fixed at 19.2K baud, 8 data bits, no
parity, and 1 stop bit.
Important: Parameters A105 - [Comm Loss Action] and A106 -
[Comm Loss Time] in the daisy-chained drives are not
used in Multi-Drive mode. If the RS-485 cable is
disconnected or broken, the disconnected drive(s) will fault.
On the DeviceNet side, Parameters 07 - [Comm Flt
Action] and 08 - [Idle Flt Action] in the 22-COMM-D
determine the action taken for ALL of the drives on the
Multi-Drive node.
The following Multi-Drive parameters must be set in the 22-COMM-D:
After setting the 22-COMM-D parameters, set the adapter Mode Jumper
from Single drive operation to Multi-Drive operation, and reset the
adapter or cycle power. Refer to
Chapter 2 , Commissioning the Adapter .
Important: 22-COMM-D parameters can be set using a DSI peripheral
(HIM, DriveExplorer with 22-SCM-232, etc.) ONLY when
the Mode Jumper is in the Single mode position.
