So I'm helping with a project that requires us to use an Arduino Uno R3 to recieve data from an Air Flow Sensor. We send the data received from the "Sensor " to the PLC via a MAX485 breakout board. My question is: Does anyone have a link or information on the logic needed to just recieve data via the Port 3 RS485 connection on the PLC?

This is a Modbus RTU Serial communication protocol. The above links may help you out.
