Capacitive electrodes EK - Profibus PA 29
If all sensors are already connected to the
bus line, the address must be adjusted via
VEGACONNECT 3, the adjustment module
MINICOM or via the mini coding switch.
Example:
To select address 37, set switch 1 (value 1),
switch 3 (value 4) and switch 6 (value 32) to
position "on". Set all other switches to position
"off".
Setup
Adjustment with PACTware TM
The adjustment with PACTware TM
corresponds to VVO adjustment, in which
case, VVO runs as a subprogram of
PACTware
TM . The adjustment instructions can
be found in the documentation of
PACTware
TM .
Adjustment with PDM
The sensors can be adjusted completely with
PDM. However, some convenient functions
and many special features, like e.g. display
of an echo curve, are not available. In
addition to the PDM software, an EDD
(available upon request from VEGA) is
required for each sensor type. The
adjustment instructions for PDM are
described in the PDM documentation.
Adjustment with the adjustment module
MINICOM
With the adjustment module MINICOM, you
adjust the individual sensor directly in the
sensor or in the external indicating instrument
VEGADIS 50. The adjustment module
MINICOM enables (with the 6 key adjustment
field with text display) all essential functions
of parameter setting and adjustment.

Device description (DD)
Beside the instrument master file (GSD), by
which a sensor is logged into the Profibus
system, and specific adjustment software,
the majority of all Profibus sensors also
requires for adjustment a so-called EDD
(Electronic Device Description) to enable
access and adjustment of each sensor from
the bus levels. This is not the case when
using VVO. The adjustment software VVO
can communicate at any time with all VEGA
sensors without the help of a special
database. Of course, all other VEGA sensors
can be adjusted with the adjustment software
as well (4...20 mA sensors or BUS sensors).
With VEGA sensors, it is not necessary to go
looking for the latest EDD. Expected by
many users, this feature is an essential
requirement for a manufacturer-independent
adjustment program.
