5.5.2 Configuration of the device address
Note the following points:
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.
All devices have the address 126 and software addressing on leaving the factory.
