4.3 Adjustment with the PC
The adjustment with the PC and the adjust-
ment program VVO is not described in this
operating instructions manual, but in the
manual "VEGA Visual Operating (VVO)“.
Beside the adjustment of VEGAFLEX, you will
find in the manual VEGA Visual Operating
further information on the scope of the
adjustment options with the PC.
If you operate a sensor in conjunction with a
VEGA signal conditioning instrument, please
use an additional communication resistor acc.
to the following table:
Before you can set up the sensors with the
adjustment program VVO (VEGA Visual
Operating), they have to be integrated into
the Profibus system. First of all, address the
sensors and connect them to your PA seg-
ment. With the attached GSD file, you inte-
grate the sensors into your system.
To set up VEGA sensors with the adjustment
software VVO, the PC or the adjustment
station on which VVO is installed must be
equipped with a Profibus DP interface card
(e.g. from Softing). The PC or adjustment
station then communicates as Master-Class 2
participant on the DP bus with the VEGA
sensors on the PA bus segment.

DP cable
To connect the PC to the DP bus, a standard
RS 485-DTE interface cable (Data Terminal
equipment) is required. With the cable, you
connect the DP interface card to the bus or
the segment coupler.
