The HART 5® protocol has provisions for creating a bus with up to 15 devices (1 to 15).
If an address greater than 0 is set via HART Command 6, the device operates in multidrop mode. Current loop node
cannot be changed using Command 6 in HART 5. The current output 31 / 32 / Uco is fixed to 3.6 mA. HART
communication takes place through current output 31 / 32 / Uco.
The HART 7® protocol has provisions for creating a bus with up to 63 devices (1 to 63).
The address and the current loop mode can be changed via HART Command 6 independently of each other. Here it is not
mandatory to also have the current output fixed to 3.6 mA with an address greater than 0.
If an address greater than 0 is set via the menu, the device will NOT switch automatically to multi-drop mode. The
current loop mode is switched independently.
operating mode for current output 31/32/Uco.
Multidrop Fixed: The current output 31/32/Uco supports the HART multi-drop mode, the current output is fixed to
3.6 mA and no longer follows the selected process variable. The process variables can be transferred via the HART
protocol.
Normal Signaling: The current output 31/32/Uco transfers the selected process variables. In addition, the process
variables can be transferred via the HART protocol.
Power Mode: The current output 31/32/Uco is set permanently to 22.6 mA and no longer follows the selected process
variable. HART communication is deactivated. The current output 31/32/Uco works as a power supply unit for the
operation of the digital output 41 / 42 as an active output.
