Which brand HMI do you want to connect to CP2E via Ethernet? Please be aware that CP2E Built-in Ethernet is FINS protocol, so if you want to use other brands HMI like Redlion or others, you need to make sure they have FINS Ethernet driver, As far as I know, you can definitely use like Redlion or proface HMI to communicate to CP2E. CP2E Ethernet can also be set as Modbus TCP server, so you are able to use Modbus TCP to connect to other brand sensor/servo/VSD via Modbus TCP.
