Item Description
Local controller in any of these combinations:
• 1756 ControlLogix controller with a 1756-CN2 or 1756-CN2R
communication module in the chassis
• 1756 ControlLogix controller with a 1756-CNB or 1756-CNBR
communication module in the chassis
• 1768-L43 CompactLogix controller with a 1768-CNB or 1768-CNBR
communication module in the chassis
• 1769-L32C or 1769-L35CR CompactLogix controller
• 1789 SoftLogix controller with a 1784-PCICS communication card
• PowerFlex 700S with DriveLogix controller and a 1788-CNx
ControlNet communication card
HMI terminal
Make sure of the following:
• The ControlNet communication modules are connected to a scheduled
ControlNet network.
• All wiring and cabling are properly connected.
How you establish communication between a PanelView or PanelView Plus
terminal and a Logix 5000 controller over a ControlNet network depends on
how you want to use controller connections.

A Logix controller supports up to 40 outgoing and 3 incoming unconnected
buffers. This limited number of incoming unconnected buffers limits how
many PanelView Standard terminals can request data from a controller.
When you use PanelView terminals with Logix 5000 controllers over a
ControlNet network, remember these limitations:
• A maximum of four PanelView Standard terminals can request data
from a Logix 5000 controller.
• The number of PanelView Plus terminals that can request data from a
Logix 5000 controller is dependent on the number of available
unconnected buffers in the Logix 5000 controller.
A typical PanelView Plus application uses 5 unconnected buffers in a Logix
5000 controller. With 32 unconnected buffers available at any time in a
Logix 5000 controller, a maximum of 6 PanelView Plus terminals can
request data from a Logix 5000 controller. Keep in mind, however, that if 6
