Some RS485 shields for the Arduino are not suitable for professional use, because they come without galvanic isolation between the RS485 bus and the Arduino. Without such isolation, it's possible to damage the Arduino or cause a malfunction of the device due to the large distances of an RS485 bus. Furthermore, a full-duplex mode (RS422) is also not integrated.
