5.6.2 Configuring the device address
The address must always be configured for a PROFIBUS DP/PA device. The valid device addresses
are in the range from 0…125. In a PROFIBUS DP/PA network, each address can only be assigned
once. If an address is not configured correctly, the device is not recognised by the master. The
address 126 can be used for initial commissioning and for service purposes.
