6.1.3 Operating mode: Multidrop (models DIH52, DIH62)
In this specially defined operating state for HART ® transmitters, the current signal is firmly
set to 4 mA and the measuring information is transmitted via the HART ® communication
to the control room. To enable the displaying of the measured value of a transmitter, the
address of the desired transmitter must be set in the "Address" menu item.
If the HART ® address is modified during operation, the establishment of a new connection
is started during which, however, the sensor must respond immediately in order to
complete the connection establishment.
The digital indicators show the measured values of the primary variable transmitted via
HART ® to the control room. The display is passive, i.e. the transmission of the measured
values must be requested by the control room. The devices function as secondary master
with respect to the sensor during the parameterisation.
6.1.4 Operating mode: Basic mode, 4 ... 20 mA (DIH50, DIH52, DIH62)
In the basic mode, all settings of the digital indicator must be carried out manually by
means of the front-side keys.

▲ (UP)
