VVO connection to the bus cable

You need a Profibus DP interface card (from
Softing) in your PC in order to adjust the
sensor with the adjustment software VVO.
This card must be used to make the connec-
tion between computer and Profibus DP
cable (a direct connection or a connection to
the Profibus PA cable is not possible). With it,
the computer with VVO has the status "Mas-
ter class 2".

4.3 Adjustment with VVO

If the oscillator CAP E34 PA Ex is installed,
the electrode can also be adjusted via a PC
with the adjustment software VVO (from ver-
sion 2.60).

Before the sensors can be operated and
adjusted with the adjustment program VVO
(VEGA Visual Operating) via Profibus PA,
they must be integrated into the Profibus
system. Address the sensors first (chapter
4.1 Adjustment media) and then connect
them to the PA segment. With the attached
GSD file (instrument master file), you then
integrate the sensors into your system. The
GSD file can be integrated by means of an
appropriate tool, e.g. Siematic Manager, into
your system.

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

If the computer is connected to the Profibus
DP cable or via VEGACONNECT 3, you can
start VVO. When connecting via VEGACON-
NECT 3, you need VVO version 2.80 or
higher.
