7.4.1 Setting the device address
PROFIBUS DP
The address must always be configured for a PROFIBUS DP/PA device. The valid address
range is between 1 and 126. In a PROFIBUS DP/PA network, each address can only be
assigned once. If an address is not configured correctly, the device is not recognized by the
master. All measuring devices are delivered from the factory with the device address 126
and with the software addressing method.
