5.5.2 Configuration of the device address
Note the following points:
• In the case of a PROFIBUS-DP/-PA flowmeter, it will always be necessary to configure
the address. Valid flowmeter addresses lie within the range 0…125. Each address can
only be used once in a PROFIBUS-DP/-PA network. If an address is not configured
correctly, the flowmeter will not be recognised by the master.
The address 126 is used for initial commissioning and for service purposes.
• All flowmeters have the address 126 and software addressing on leaving the factory.

Addressing PROFIBUS-DP/-PA using miniature switches:
Warning:
Risk of electric shock. Exposed components carry dangerous voltages. Make sure that
the power supply is switched off before you remove the cover of the electronics com-
partment.
1. Loosen the Allen-head screw securing the clamp (3 mm key).
2. Remove the cover of the electronics compartment.
3. Remove the local display (if existing) by loosening the fixing screw of the display
module.
4. Use a pointed object to alter the positions of the miniature switches on the I/O
board.
5. Installation is the reverse of the removal procedure.

a Miniature switches Nos. 1–7 for defining the bus address (for example: 1 + 16 + 32 = 49)
b Switch for the address mode (type of addressing):
OFF = software addressing via the local display
ON = software addressing via miniature switches No. 1–7
