EtherNet/IP I/O Considerations
When you add EtherNet/IP I/O at runtime:
• the EtherNet/IP I/O modules you add at runtime use can be:
– added to existing rack-optimized connections.
– added to new rack-optimized connections.
– added as direct connections.
You can create new rack-optimized connections when adding
EtherNet/IP I/O modules at runtime.
• you can add I/O modules until you reach the limits of the
communication module.
