VEGA D91 Profibus PA - Manual (Page 26)

26 Pressure transmitter D91 (Profibus PA)
Setup
If you have already connected several VEGA
sensors to the bus, you can select the sen-
sor to be configured, in this case pressure
transmitter D91. The serial number and the
bus address of the sensors are displayed to
enable clear identification.
The menu language of the sensor can be
selected (only relevant with a sensor with
menu-driven adjustment) and the units for the
output of sensor values can be set. If ad-
dress 126 is adjusted on the sensor, you can
assign a bus address to the sensor in the
field "Sensor address". Then click to
Save .
Sensor configuration
After starting VVO as previously described
or having made connection to the Profibus,
the following presentation will be displayed
on the monitor. Click to
Configuration , then
to Measuring system .
Information about the sensor identifica-
tion number:
You do not have to modify the adjustment
"VEGA specific No.". Only if you want to make
sure that the pressure transmitter can be
replaced on the Profibus by a sensor of
another manufacturer do you have to choose
the option "Profile specific No.".
Configuration measurement loop
Click to Configuration , point to Measure-
ment loop , then click to Modify .
Now all instruments which are connected to
the bus are shown (identifiable by the bus
address and the serial number). Notice that
in this example, the same serial number ap-
pears twice. This is a sensor with a measure-
ment loop for a pressure and a second
measurement loop for temperature. Choose
the sensor (the measurement loop) with
which you want to create a measurement
loop and click to
OK .
