Online Additions - ControlNet Considerations
ControlNet considerations that must be made depend upon the ControlLogix
ControlNet modules you are using.
1756-CNB and 1756-CNBR Modules
When you add I/O to the ControlNet network via the 1756-CNB or
1756-CNBR modules while online, these considerations must be made:
• Digital I/O modules can be added as rack-optimized connections if the
parent module is already configured with rack-optimized connections.
• Digital I/O modules can also be added as direct connections.
• Analog I/O modules can be added only as direct connections.
• Disable the Change of State (COS) feature on digital input modules
because it can cause inputs to be sent more quickly than the RPI.
While you can add a new digital I/O module to an existing rack-optimized
connection, you cannot add rack-optimized connections while online.
