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").
When the mini coding switch is set to ad-
dress 126 or higher (factory setting), the
address can be modified via software (with
VVO). However, this is only possible if the
transmitter is connected as the only partici-
pant with address 126 on the bus. For this
reason, we recommend adjusting the ad-
dress 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.
