Rockwell Automation 1395 ControlNet Communication Board - Manual (Page 60)

4–6 Installation
Publication 1395.5.37 – March, 1999
ControlNet Connections To make the ControlNet connection to the CNA board, connect the
approved cable per Table 4.B to the CNA Board connector
1784-RPFS configured for ControlNet communications, and the
ControlNet Network tap connector. Refer to Figure 4.3 for details on
connecting to the CNA connectors in either redundant or
non-redundant mode.
!
ATTENTION: When breaking connections at Channel A (and B
when a redundant connection is present) on any CNA Board,
communications will be interrupted to the 1395 Drive. Depending
on the application, a loss of control to devices connected to the drive
could cause hazardous system operation. To guard against personal
injury, the system must be shut down, or local control maintained of
critical devices when making or breaking connections at the Primary
or Redundant Connection on the Board.

Multiple Drive Connection – When more than one CNA board
equipped Drive is connected to a ControlNet Network, it must have its
own separate connection to the Network and a unique node address as
determined by dip switch U6.
