The values to be written must be entered in the range DB120x.DBB1008...11 in the data type specific for the appropriate
variable.
If necessary, the values are converted (e.g. NCL floating-point values (64-bit) into the PLC format (32-bit) and vice versa). A
loss of accuracy results from the conversion from 64-bit to 32-bit REAL. The maximum accuracy of 32-bit REAL numbers is
approximately 10

.
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 as of DB120x.DBB3004 is 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
The range DB120x.DBB3004...07 is not relevant for writing.

Variable cuttEdgeParam
Compensation value parameters and cutting edge list with D numbers for a tool.
The meanings of the individual parameters depend on the type of the tool in question. Currently, totally 25 parameters are
reserved for each tool edge (but only a part of them is loaded with values). To be able to remain flexible for future extensions,
it is not recommended to use a fixed value of 25 parameters for calculation, but the variable value 'numCuttEdgeParams'
(variable index 2).
For a detailed description of the tool parameters, please refer to Chapter "Tool Offset (Page 180)".
