3.2 3.2.1 3-7 <3. Parameters> Setting Parameters Burst Mode The AV550G continuously sends the data stored in it when burst mode is set “On”. Either one of measured value, % output value, or 4 to 20 mA output value can be selected and sent. The data is sent periodically at 75 ms intervals as a digital signal when the AV550G is set in burst mode. Therefore, communication by the HART simultaneous communicator is also possible. Setting of Burst Mode Call up “Burst option” display. 1.Device setup ---> 4.
3-8 3.2.2 <3. Parameters> Multidrop Mode Field devices in multidrop mode refer to the connection of several field devices on a single communication line. Up to 15 field devices can be connected when set in multidrop mode. To activate multidrop communication, each field device address must be changed to a unique number in the range 1 to 15. This change deactivates the 4 to 20mA output and changes it to 4mA. Setting of Multidrop Mode Call up “Poll addr” display. 1.Device setup ---> 4.Detailed setup ---> 4.
