The AXFA11 continuously sends its stored data when the “Burst mode” is set to “On”.
Any one of instantaneous flow rate, output in %, totalization values or current output can
be selected and sent. The data is sent intermittently as a digital signal when the AXFA11 is
set in the “Burst mode.

8.3.4.8 Example 5 of Other Settings: Multidrop Mode
Field devices in “Multidrop Mode” refers to the connection of several field devices on a
single communication line. Up to 15 field devices can be connected when set to the
multidrop mode. To activate multidrop communication, the field device address must be
changed to a number from 1 to 15. This change deactivates the 4 to 20 mA output and
changes it to 4 mA.
