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
To write NC variables, the same configuration steps are required as for reading NC variables.
It is useful to store the address data of all NC variables to be read or written in a DB.

Note
Job must be repeated since queue is full
FB1 parameter "NCKomm" is not set
"SD1" - "SD8" must not be local data
Job must be repeated
"Unit" or "Column"/"Line" contains value 0
Check "Addr" (or variable name), "Area", "Unit"
Check parameter "NumVar"
meterized
Remedy: Write fewer variables per job or use
shorter string variables
