Modicon M241 I-O LED can not disable

Hello Everyone,


I am new in terms of program the M241 with soMachine 4.3.

I realize that the red LED I/O is always ON (red) when i don't have the ethernet cable connected in the frontal port.


So, my M241 is stand-alone application and i don't need this connection.
How i can disable the ethernet interface in soMachine?

I find in internet some explanations (like the code in attachment), but i cant implement in my program. It appears always build errors. Can you help me? Thanks

Best Regards,

You can make RJ45 loopback adapter, after that PLC thinks that there is link active or port and led isn't lit.
