The sensor offers the HART modes standard and Multidrop. In this
menu item you specify the HART mode and enter the address for
Multidrop.
The mode "standard" with the fixed address 0 means outputting the
measured value as a 4 ... 20 mA signal.
In Multidrop mode, up to 63 sensors can be operated on one two-wire
cable. An address between 1 and 63 must be assigned to each sen-
sor.

The default setting is standard with address 0.
The instrument settings are copied with this function. The following
functions are available:
•
Store data from the sensor into the display and adjustment mod-
ule.
•
Store data from the display and adjustment module in the sensor
The following data or settings for adjustment of the display and ad-
justment module are saved:
•
All data of the menu "Setup" and "Display"
•
In the menu "Additional settings" the items "Distance unit, tem-
perature unit and linearization"
•
The values of the user programmable linearization curve
The copied data are permanently saved in an EEPROM memory in
the display and adjustment module and remain there even in case of
power failure. From there, they can be written into one or more sen-
sors or kept as backup for a possible sensor exchange.
The type and the volume of the copied data depend on the respective
sensor.
Note:
Before the data are stored in the sensor, a check is carried out to
determine if the data fit the sensor. If the data do not fit, a fault signal
is triggered or the function is blocked. When data are being written
into the sensor, the display shows which instrument type the data
originate from and which TAG-no. this sensor had.
In this menu, you read out the instrument name and the instrument
serial number:
The 4 ... 20 mA signal of the HART sensor is switched off. The sensor
1)
consumes a constant current of 4 mA. The measuring signal is transmitted
exclusively as digital HART signal.
