Program correction
As soon as a syntax error in the part program is detected by the controller,
program execution is interrupted and the syntax error is displayed in the
alarm line.
Depending on the state of the control, you can make the following correc-
tions using the program correction function:
Stop-Mode (Only program lines that have not yet been executed can be
edited.)
Reset-State (All program lines can be edited)
Note:
The "Program correction" function is only available for part programs in the
NC memory, not for external execution (e.g. on USB media).
