Configuration of the device address

Note the following points:
x In the case of a PROFIBUS-DP/-PA device, it will always be necessary to configure the
address.
Valid device 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
device will not be recognised by the master.
The address 126 is used for initial commissioning and for service purposes.
x All devices have the address 126 and software addressing on leaving the factory.
