Most likely the issue is the cable between the load cell and the plc.

Omron pin out is NOT standard.  You will typically need to make a cable.

Please check the documentation for the pinout of the plc port.

Hope this will help.

Dear All

Thanks for your help

I connect it with the MRTU_CPU_Fn03

The problem was related to pin 4 and 5 that should be connected together.

Thanks again
