Setup
4.3 Adjustment with the PC
Before you can adjust the sensors with the
adjustment program VVO (VEGA Visual
Operating), they must 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 adjust 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. of Messrs. Softing). The PC or the ad-
justment station communicates then as Mas-
ter-Class 2 participant on the DP bus with the
VEGA sensors on the PA bus segment.
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 on the bus or
to the segment coupler.

If the computer is connected to the Profibus
DP cable, you can start VVO.
• Switch on the power supply of the con-
nected sensor.
• Start the adjustment software VVO (VEGA
Visual Operating) on your PC.
• In the entrance window you choose with
the arrow keys or the mouse the item Plan-
ning and click to OK.
You should only choose
Planning if you are
authorised to modify instrument param-
eters. Otherwise choose
Operator or Main-
tenance.
In the window
User identification you are
asked for the name and the password.
• For setup ( planning) enter under name:
VEGA and under password also: VEGA. It
does not matter if you use capital or small
letters.
VVO determines automatically the type of the
connected sensor and shows shortly with
which sensor a connection exists.
Further information on the adjustment with
PC and the adjustment software VVO is
stated in the operating instructions of the
adjustment software VEGA Visual Operating
(VVO).
