Job evaluation

Key statement
The variable-specific result interface must be evaluated for each variable processed in the job.

1) DB120x, with x = 0 ... 7 corresponds to variable 1 ... 8.
2) Only for predefined variables of the "Read/write NC variable" user interface
3) Only for variables from DB9910 NC_DATA
Note
Channel-specific variables
When reading/writing channel-specific variables, only the variables of exactly one channel may
be addressed in a job.
Drive-specific variables
When reading/writing drive-specific variables, only the variables of exactly one SERVO drive
object may be addressed in a job. The SERVO drive object must be assigned to a machine
axis of the NC. The line index corresponds to the logical drive number.
Error case
In the event of an error, reading/writing variables from different drive objects, or simultaneously
from a channel and a drive object, an error message is output:
DB1200.DBX3000.1 == 1 (error occurred)
