Drive-specific variables
If an error occurs while reading/writing a drive-specific variable (DB1200.DBX3000.1 == 1),
an error number is displayed in the access result which is based on the error numbers defined
in the PROFIdrive profile.
State
Determining the significance of the access result:
1. Calculation of the error number of the PROFIdrive profile
<Error number of PROFIdrive profile> = result of access - 20
2. Determining the significance of the error number of the PROFIdrive profile
The error numbers of the PROFIdrive profile are described in:

Configuration steps
Proceed as follows to read NC variables:
● Select variables with the NC VAR selector.
● Save selected variables in a *.VAR file.
● Generate a STEP 7 *.STL source file.
