Adjustment with the adjustment pro-
gram VVO - VEGA Visual Operating
Setup and adjustment of the ultrasonic sen-
sors is generally done on the PC with the
adjustment program VEGA Visual Operating
(VVO) under Windows
® . The program leads
quickly through adjustment and parameter
setting by means of pictures, graphics and
process visualisations.
The VEGA adjustment software VVO (VEGA
Visual Operating) operates either as a
subprogram of the host program PACTware
TM
(according to the FDT concept) or as an
independent adjustment program on any PC,
engineering station or process control com-
puter.
We are aware of the disadvantages of the
HART
® environment: for each sensor/partici-
pant an individual DD must be loaded which,
in addition, must always be the latest and
most up-to-date DD. Special adjustment
options such as e.g., the output of an echo
curve, are available neither with HART
® nor
with PDM. The SIMATIC-PDM adjustment
concept was tailored more to the basic ad-
justment functions. Intelligent, communicative
sensors, however, make much more addi-
tional information available to the measure-
ment loop and open up completely new ad-
justment possibilities. PDM was not
conceived with such things in mind. Really
user-friendly adjustment is out of the ques-
tion. That’s history now.
The legitimate wish of many Profibus users
for a manufacturer-independent adjustment
tool without EDD has now been realised with
PACTware
TM 1) . An association of a number of
process technology companies developed
PACTware
TM : a Process Automation Configu-
ration Tool, running different manufacturer
software tools under a standardized user
interface and adjustment structure. Special-
ists call this technology Field Device Tran-
scription. Just as different as Windows
printer drivers enable operation of completely
different printers under one user interface,
PACTware
TM enables operation of all field
instruments under one user interface. Instru-
ment-specific databases (EDD), like those
required for SIMATIC PDM, are not neces-
sary.
As a result of this development, three adjust-
ment media are now available for VEGA-
Profibus sensors:
- adjustment with the PC and the adjustment
program VVO (VEGA Visual Operating) as
a stand-alone tool which can, however, also
run as a subprogram of PACTware
TM
- adjustment with the detachable adjustment
module MINICOM in the sensor
- adjustment with the SIMATIC PDM adjust-
ment program (requires EDD instrument
databases for advanced adjustment)

The adjustment program recognises the sensor type
1) presumably available until end of 2000
