Figure 3.1 presents an overview of the CNA board with a typical
Channel configuration. The parameter numbers shown are for a CNA
board mounted in Port B of the Drive. This is the standard Port for the
CNA Board.

Communications When you use the ControlNet Adapter Board for ControlNet
communications, the drive looks like a remote I/O chassis to a PLC.
This allows you to use discrete data transfer.
With discrete data transfer, the PLC controller’s I/O image table is used
to transfer the data that the drive needs to have continuously updated
ControlNet has the option for redundancy. Redundancy for the entire
network is determined by the configuration tool (RS Networx
TM ).
Below is a listing of the CNA features on this Adapter:
S The board can be configured as a full I/O rack only.
S The board can be configured to ignore PLC fault conditions and
continue Drive operation.
!
ATTENTION: Configuring the board to ignore PLC
fault conditions could lead to erratic operation and
possible Drive or equipment damage.
S The messaging mechanism can support transfer of multiple Drive
parameters (up to 5) in a single request.
S A “redundant” feature allows the Drive to be connected to a
redundant network
