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)

Visualised input of a vessel linearisation curve

The adjustment program recognises the sensor type

1)

presumably available until end of 2000
