6.2 Adjustment with VVO
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 (chapter "5.2 Sensor address“) and
connect them to your PA segment. With the
attached GSD file you integrate the sensors
into your system.
To adjust the VEGA sensors with the adjust-
ment 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 to the bus or to
the segment coupler.
