Approx. 10 minutes after the last pressing of a key, an
automatic reset to measured value indication is triggered. Any
values not confirmed with [OK] will not be saved.

6.2 Setup procedure

Setup encompasses mainly the selection of the application,
assignment of HART addresses and adjustment of measure-
ment loops. Scaling the measured value to the requested size
and unit (possibly with the application of a linearization curve),
as well as setting an integration time for smoothing the
measured value, are additional setup steps.
For instruments with Ethernet interface, the instrument must be
provided with the host name and IP addr./Subnet mask. If
necessary, the e-mail/web server can also be configured with
PACTware™.
VEGASCAN 693 can process measured values of several
connected HART sensors. All measured values are trans-
mitted as digital HART signals on the same cable (bus). An
analogue 4 ... 20 mA transmission is not possible. An own,
unique address (address range 1-15) must be assigned first of
all to each connected sensor. This mode is also called HART
multidrop mode. Addressing can be done directly on each
HART sensor via the respective adjustment unit or an
appropriate adjustment software. As an alternative, the setting
of the sensor address can be also carried out via the
VEGAMET menu under "Service - Sensor address".
Note:
When addresses are being assigned, only one sensor with a
particular address must be connected on the bus. If this is not
the case, the sensor cannot be accessed and it is not possible
to assign an address.
