Every DP/PA device type has to have an individual Ident Number. This number is required by the DP master to be able to identify the connected device types. The master compares the Ident Number of every connected device with the Ident Number in the configuration database. User data transfer in the adjustment phase is only possible when the right Profibus DP slave is connected under the correct address. This ensures very good protection against parameterization errors.
