VEGA Visual Operating (VVO)
VVO connection to the bus cable
To operate the sensor with the adjustment
software VVO, you require a Profibus DP
interface card (from Messrs. Softing) in your
PC. This card must be used to provide the
connection between computer and Profibus
DP cable (a connection directly to the sensor
or to the Profibus PA cable is not possible).
The computer with VVO then has the status
"Master, class 2".
If the computer is connected to the Profibus
DP cable, you can start VVO. If the following
presentation is shown on the monitor, you
have to modify the communication settings in
VVO. To do this, click to
Configuration , point
to Program and click to Communication .
First click in the window "Communication" to
Profibus DP for PA sensors . Then select the
Profibus card installed in your PC. It is also
possible to modify the settings for baud rate,
further bus parameters and master address.
Note:
Make sure that the master address you are
using is not assigned to another bus partici-
pant!
Click to OK , if you are finished with the com-
munication settings. You then have to restart
VVO.
