Modbus TCP Schneider M340 NOC0401

[JEANST]

Hello, this is a message for specialists in Schneider, I am trying to establish communication in modbus tcp between a schneider M340 (P3420302) API equiped with a NOC0401 card (The integrated port is already taken for communication with a PC software.) Concerning the NOC0401, the top port (1) is taken by the communication with an HMI HMIGTO4310 port 2 is taken by a communication in Ethernet/IP with a KUKA robot. Ports 3 and 4 are free, I can connect to them to go online with the API without any problem. My question : Is communication in Modbus TCP possible in read_var/write_var on ports 3 or 4 of the NOC? knowing that I use ethernet/IP on port 2. or is it possible by the integrated cpu port if I connect it to a switch to keep the existing PC communication AND my modbus/tcp com. OR I'm unlucky and have to buy a new NOC0401 card.. So I hope I was clear, Looking forward to your proposals thank you in advance and good evening

You can just use the integrated ethernet port on the cpu. But regarding the NOC card the bottom two ports are normally used for connecting to LAN and the top two for connecting to field devices.
I would use the integrated cpu port for what you want to do
