Using Modbus or HART

To use the HART protocol, it is necessary to select the applicable current (1.25 mA or 3.5 mA). The factory default setting is 3.5 - 20 mA. This setting can only be changed through HART or Modbus.

Settings for Modbus and HART can be changed through the DIP switch.

For information about changing device settings through Modbus, refer to the FL500 Modbus Communication Operating Manual (PN 10193214).

For information about changing device settings through HART, refer to the FL500 HART Communication Operating Manual (PN 10193215).
