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.
