Communication / ...HART
Device Address
Selection of HART device address.
Note
The HART protocol has the option of creating a bus with up to 15 devices (1 ... 15).
If an address greater than 0 is set, the device operates in multidrop mode. The current output 31 / 32 / Uco is fixed to 4 mA.
HART communication takes place only through current output 31 / 32 / Uco.
Loop Current Mode
Selection of the 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.
HART Tag
Entry of a HART TAG number as unique identifier for the device.
Alphanumeric, a maximum of 8 characters, upper case only, no special characters.
HART Long Tag
Entry of a HART TAG number as unique identifier for the device.
Alphanumeric, maximum of 32 characters, ASCII
Only starting from HART version 7!
HART Descriptor
Entry of a HART descriptor.
Alphanumeric, a maximum of 16 characters, upper case only, no special characters.
HART Message
Display of the alphanumeric TAG number.
HART Manuf. ID
Display of the HART manufacturer ID. ABB = 26
HART Device ID
Display of the HART device ID.
HART Find
Select whether the transmitter must respond to the HART command 73 (Find Device).
• Off: The transmitter does not respond to command 73.
• Once: The transmitter responds once to command 73.
• Continuous: The transmitter always responds to command 73.
Last HART Command
Display of the most recently sent HART command.
PV Primary Variable
Selection of process variables that are issued through the HART variables.

SV Secondary Var.
TV Tertiary Variable
QV Quaternary Var.
