You'll need to add a V100-17-RS4X communication card to the Samba. 

After that, read the the Help on the Protocol function block and look at Help->Examples->Version 900->Project Examples->Communications->Modbus to see how to set Modbus up.  

If you still have trouble have post your program and a link to the datasheet on the sensor so we can have a look.
