About Your Controller Chapter 2
When the new node address is configured and applied, the port is not restarted.
You can verify that the node address has changed after performing RMCC by
looking at the Communication Diagnostics tab for the controller.
RMCC Modbus Example – Verify Address Change
Using EtherNet/IP Communication
To use RMCC with the EtherNet/IP communication protocol, the controller
must be configured to use a static IP address. If the controller is configured to use
BOOTP or DHCP, the change will be rejected. A CIP Generic message is sent
from within a program with the following parameters.
Use RMCC when configuring the controller during commissioning. Immediately
after changing the IP address, the cycle time may increase up to 100 ms for one
program scan.
You must ensure that the new node address being configured is unique
as it will not be checked against existing node addresses of other
devices.
