Configuring the device address
The address must always be configured for a PROFIBUS PA device. The valid device addresses are
in the range from 1 to 126. In a PROFIBUS 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 address 126 and with software addressing.
