Chapter 2 About Your Controller
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.
