6.1.2 Operating mode: HART ® master (model DIH52)
The master mode enables the modification of the measuring range, the unit, the format,
the damping and the polling address of the connected HART ® transmitter. Further
modifications to the configuration of the transmitter (e.g. selection of the sensor) are not
possible.
During the starting procedure, the field displays try to contact the connected HART ®
transmitter in the master mode and to apply its settings (unit and measuring range). During
the connection establishment, the status line shows the message "Connecting HART ®" .
When a HART ® sensor is detected, the HART ® symbol is displayed. The field indicator
switches to the HART ® mode and starts operation using the settings received from the
transmitter. This procedure is repeated whenever the power supply is switched on.
When pressing any key during the starting process or the device has not detected any
HART ® transmitter during approx. 70 seconds, the digital indicator switches to the basic
mode and starts operation on the basis of the factory settings.
6.2 Configuration
For configuration of the field instrument a software (e.g. WIKA_T32) or a HART ®
communicator is necessary.
The following parameters can all be configured: sensor model, sensor connection, user
measuring range, output limit, alarm indication, terminal voltage monitoring, sensor break
monitoring, measuring range monitoring, measuring rate, damping, write protection, offset
values (1-point correction), TAG no. and user linearisation (custom characteristic curve).
Furthermore, a linear transformation of the process value is possible using a 2-point
correction.
User linearisation:
Via software, customer-specific sensor characteristics can be stored in the transmitter in
order to define other sensor types. Number of auxiliary points: min. 2; max. 30. If more than
2 sensors are connected (dual sensor function) further configurations can be carried out.
With the dual sensor function, two identical sensors (resistance sensor or thermocouple)
with the same measuring range are connected and then processed together.
The field instruments are delivered with a basic configuration (see data sheet TE 62.01) or
configured according to customer specifications. If the configuration is changed afterwards,
the modifications must be noted on the label using a water-resistant felt-tip pen.
A simulation of the input value is not required to configure the TIFxx. A sensor
simulation is only required for the functional test. For model TIF52 unit und
measuring range can be configured via operating unit.
