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 by which it is identified on the bus,

the address 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).
