9.6 If-then decisions with Q parameters
Application
The TNC can make logical if-then decisions by comparing a Q
parameter with another Q parameter or with a numerical value.
If the condition is fulfilled, the TNC continues the program at the
label that is programmed after the condition.
Further Information: "Labeling subprograms and program section
repeats", page 306
If it is not fulfilled, the TNC continues with the next block.
To call another program as a subprogram, enter a % program call
after the block with the label.
Unconditional jumps
An unconditional jump is programmed by entering a conditional
jump whose condition is always true. Example:
D09 P01 +10 P02 +10 P03 1 *
