Capacitive electrodes EL - Profibus PA 29
If all sensors are already connected to the
bus cable, the address must be set 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 corre-
sponds 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 addi-
tion to the PDM software, an EDD (available
upon request from VEGA) is required for
each sensor type. The adjustment instruc-
tions for PDM are described in the PDM
documentation.
Adjustment with 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 re-
quires a so-called EDD (Electronic Device
Description) to enable access and adjust-
ment of each sensor from the bus levels. This
is not the case when using VVO. The adjust-
ment 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 VBUS sensors). With VEGA sen-
sors, 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 pro-
gram.
