for management.
Currently the DB management is not used
– for this reason all parameters can be
left at their default settings (0)
Pos_of_DB
Number (1
– n) of the current data block for the parameter block
0: not used
No_of_all_DBs
Total number (n) of data blocks for the parameter block
0: not used
DB_No_Act
DB number of the current data block
0: not used
DB_No_Prev
DB number of the previous data block, if one exists.
Otherwise: 0
DB_No_Next
DB number of the subsequent data block, if there is another one.

Info_Management
Parameter blocks containing an enumeration have one information block 'Info
management'. It contains following information
The values of the information management parameters are already preset and
therefore do not need to be modified.
P_Byte_First_Info
Byte position of the first data record in this DB, may not be changed
No_of_Infos
Number of data records contained in this DB
0: unspecified -> the data block end marks the last data record
Len_Info
