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.
