Rexroth IndraMotion MTX 11VRS Standard NC Operation
Once this box is confirmed, the program execution continues.
If a variable is an array, the breakpoint can also be set to such a variable. The
program execution is interrupted in two cases:
●
By reaching an NC block using an element of this array.
●
By changing the value of an element of the array.
A breakpoint can be set only on the whole array, not on an individual
element.
Special aspect when working with breakpoints on permanent variables:
Permanent variables (permanent and permanently-defined variables) are not
used in the NC program. However, if a breakpoint is set on such a variable, the
execution of the NC program is interrupted if the value of this variable changes.
This may be carried out either by the NC or in the editing mode with the help of
the NC-Analyzer.
Breakpoints on variables have an effect on the available number of the varia‐
bles to be watched in "Watch mode". For example, if there are 10 active
breakpoints on variables, the user cannot set more than 30 variables in "Watch
mode".
If the available number of active breakpoints on variables is exceeded, a warn‐
ing message appears on the screen.
To set a breakpoint on a variable, the following steps have to be carried out:
●
Activate the "Variables window" via "Navigation" or "Next window".
●
To select individual elements of variable structures, use the F-key <F8
Expand substructure/Close substructure>.
●
The access mode for the breakpoint is defined in the opening "Break‐
point" dialog. The "Write mode" is set by default.
To activate a breakpoint on a variable or change its access mode, open the
"Breakpoint" dialog. Use the "Dialog" buttons to make changes.
Example:
18 B=1
19 A=0
20 A=B+5
21 A=7
22 A=10
23 C=A
In "Write" mode, the value of variables A is updated every time the variable gets
a new value in each line.
In "Read-only" mode, however, only the display of the variables A in line 23 is
updated, as the value is read in this line only.
When working with the NC-Analyzer, messages of the NC and the NC-Analyzer
are displayed in the "Output" window. This is important, since an error is often
displayed by an NC runtime error message. In the "Output" window, an NC error
