    Address DB_Ad and Length DB_Ad_Lg  Every data element in a device is stored in a database. In some implemen fuel dispenser tations it may be real  database or only a software organisation (object or tasks) for instance if a separate processor  manages each meter. So the addressing mode must be flexible enough to address any database  level.  FP2_1.84 IFSF STANDARD FORECOURT PROTOCOL February 2003   fuel dispenser COMMUNICATION SPECIFICATION   Page: 14  These database levels are addressed by the Database Address (DB_Ad) using a variable  number of bytes which is indicated in the Database Address Length (DB_Ad_Lg) field.  The number of address bytes to specify a database is 1 to 8.  Every forecourt application document (IFSF-document Part III) has a description showing   fuel dispenser how these addresses are specified.  The only common definition for every forecourt device is to use the first byte of the database  address as follows: 00H for Communication Service Data   01H for Common Data in a device   DB_Ad   Byte 1 Byte 2 Byte 3 Byte 4 Byte 5 Byte 6 Byte 7 Byte 8   00H 00H-FFH 00H-FFH 00H-FFH 00H-FFH 00H-FFH 00H-FFH 00H-FFH   Communi- Application Application Application Application Application Application Application   cation dependent dependent dependent dependent dependent dependent dependent   Service   01H   Common   Data   02H-FFH   Application   dependent  3.2.4 Application Data Data  The Application Data consist of the Data Identifier Data_Id the Data Length Data_Lg  and the Data Element Data_El.
