4.2 Adjusting the sensor with the
adjustment module MINICOM
Beside the PC, you can use the small, de-
tachable adjustment module MINICOM to
carry out the adjustments directly in the sen-
sor.
With the adjustment module MINICOM, only
the sensor-relevant adjustments such as e.g.
scaling of the sensor display, operating
range, meas. conditions, sensor display
scaling or false echo storage are possible.
Not possible, however, are all adjustment
steps relating to configuration, conditioning
and signal processing (configuration of the
inputs and outputs, linearisation curves,
simulation …). This is only possible with the
PC.
The adjustment module MINICOM is oper-
ated with 6 keys. A small display shows you
apart from the measured value, a short mes-
sage on the menu item or the value entered in
a menu.
The volume of information of the small display,
however, cannot be compared with that of the
adjustment program VVO. Nevertheless with
the help of the menu schematic for MINICOM
you will be able to quickly find your way
through the adjustment structure. In time, you
might even be able to carry out your adjust-
ments with the small module faster and more
efficiently than with the PC.

4.1 Adjustment media
In chapter „1.4 Adjustment“ the Profibus
adjustment structure was briefly explained
and the adjustment media for VEGA Profibus
sensors were shown. All VEGA Profibus
sensors operate in profile 3 and can be ad-
justed with:
- the adjustment software PACT
ware TM
- the Siemens software PDM in conjunction
with an EDD (Electronic-Device-Descrip-
tion)
- the adjustment module MINICOM in the
sensor.
Adjustment with the PC
The adjustment software PACT ware TM enables
user-friendly adjustment of VEGA Profibus PA
sensors. All functions and options of sensor
adjustment are accessible. The program
runs under Windows
® on a PC with a
Profibus-Master-Class 2 interface card on
Profibus DP level as Master-Class 2 tool. The
adjustment software accesses the VEGA PA
sensors via the DP bus, the segment coupler
and the PA bus.
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
on request from VEGA) is required for each
sensor type. The adjustment instructions for
PDM are described in the PDM documenta-
tion.
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.
