With the arrow key and the "OK“ key, you
move to the menu item "Instrument address“.
There you can adjust the address (0 … 125)
with the "+“ and "–“ key. Save the adjusted
address with the "OK“ key.
Also, the other adjustment steps (adjust PA
output, adjustment etc.) can be carried out
when the DMU is connected to a power sup-
ply unit. However, adjustment is also possible
at a later time (when the DMU is connected to
the bus cable).
4 Setup
Electrical connection and setup can be sim-
plified by temporarily mounting the cover or
the display module on VEGABAR laterally or
displaced downwards.

4.1 Adjustment of the Profibus PA
address
Since each bus participant must have its own
address it is identified on the bus, the ad-
dress must be adjusted before setup of the
transmitter. Depending on the instrument
version, this is done either with the module
"Menu-driven adjustment“ or with the mini
coding switch.
Address adjustment with the module
"Menu-driven adjustment with addi-
tional functions“
As a standard feature, the address of the
Profibus PA transmitter is set to "126“. For
modification of the address via the keyboard,
the transmitter must be connected to the
power supply. This must not be the bus ca-
ble. You can use a standard power supply
unit or a battery (9 … 32 V DC, 10 mA).
