Writing Variables From The Nck Area - Siemens SINUMERIK 808D Function Manual

Values:
The range DB120x.DBB1008 ... 11 is not relevant for reading.
Result, variable-specific part
A result is reported for each variable in the job.
If the read process was successful, "Variable valid" (DB120x.DBX3000.0) is set to 1; the access result DB120x.DBB3001 is
0.
When reading, the data from DB120x.DBB3004 are entered type-specifically.
In case of error, DB120x.DBX3000.0 remains "0", and an entry is made in the access result DB120x.DBB3001:
● 0: No error
● 3: Illegal access to object
● 5: Invalid address
● 10: Object does not exist
Values:
When reading, the read data are in the range DB120x.DBB3004...7, in the data type specific for the respective variable (if
required, the values are converted from 64-bit to 32-bit REAL).

Writing variables from the NCK area

1 to 8 values can be written with a write job (variable x: 0...7). There is a variable-specific part of the interface for this:
● Job: DB120x.DBB1000
● Result: DB120x.DBB3000
Job, variable-specific part
NC variable:
The NC variable is selected in the variable index (DB120x.DBB1000) (see Section "NC variable (Page 21)").
Area number, column / line index (DB120x.DBB1001 ... DB120x.DBB1005)
Various variables are declared as fields. For flexible addressing, the relevant field index must be specified as a column
and/or line index (e.g. R parameter no.).
