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
