Address adjustment with the module
"Menu-driven adjustment with addi-
tional functions"
The Profibus PA transmitter is delivered with
the address set to "126". To modify the ad-
dress via the keyboard, the transmitter must
be connected to the power supply. This does
not have to be over the bus cable. You can
use a standard power supply unit or a bat-
tery (9 … 32 V DC, 10 mA).
4 Setup
4.1 Setting the Profibus PA address
Since each bus participant must have its own
address by which it is identified on the bus,
the address must be adjusted before setup
of the transmitter. Depending on the instru-
ment version, this is done either with the
module "Menu-driven adjustment" or the
address switch.
Address adjustment with the address
switch
Setup
The transmitter is delivered with the address
set as shown (all switches position "on").
If the mini coding switch is set to address
126 and higher (factory setting), the address
can be modified via software (with VVO).
However, this is only possible if the transmit-
ter is connected as the only participant with
address 126 on the bus. For this reason, we
recommend adjusting the address of the
sensor via the hardware (switch) before
connecting to the bus.
Example:
To select address 37, set switch 1 (value 1),
switch 3 (value 4) and switch 6 (value 32) to
position "on". Set all other switches to position
"off".
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.
