5.5.2 Device address
Selecting the device address
• Every PROFIBUS PA device must be given an address. If the address is not set correctly, the device
will not be recognised by the process control system.
• A device address may appear only once within a particular PROFIBUS-PA network.
• Valid device addresses are in the range 1 and 126. All devices are delivered from the factory with
the software address 126.
• The default address can be used to check the function of the device and connect it to an operating
PROFIBUS PA system. Afterwards the address must be changed to allow other devices to be
connected to the network.
Software addressing
Software addressing comes into operation, when DIP-switch 8 is in the position "ON".
BA034S/04/EN describes, how to set the address in this case.

Hardware addressing comes into operation, when DIP switch 8 is in the position "HW (OFF)". In
this case the address is determinded by the position of DIP-switches 1 to 7 according to the
following table:
Switch No.
Value in position "OFF"
Value in Position "ON"
The new address becomes valid 10 seconds after switching.
It results a new device restart.
