7 Programming with Q Parameters
7.4 If-Then Decisions with Q Parameters
The TNC can make logical If-Then decisions by comparing a Q parameter
with another Q parameter or with a numerical value.
Jumps
The jump target is specified by a label number in the decision block. If the
programmed condition is fulfilled, the TNC continues the program at the
specified label. If it is not fulfilled, it continues with the next block.
To jump to another program, enter a program call with % (see page 6-8)
after the block with the target label.
Unconditional jumps
An unconditional jump is programmed by entering a conditional jump
whose condition is always true. Example:
If 10 equals 10, go to label 1
D09 P01 +10 P02 +10 P03 1
Select the jump function to display the following options:
Overview
Soft key
D9: IF EQUAL, JUMP
Example: D09 P01 +Q1 P02 +Q3 P03 5
∗
If the two values or parameters are equal,
jump to the given label.
D10: IF NOT EQUAL, JUMP
Example: D10 P01 +10 P02 –Q5 P03 10
∗
If the two values or parameters are not equal,
jump to the given label.
D11: IF GREATER THAN, JUMP
Example: D11 P01 +Q1 P02 +10 P03 5
∗
If the first value or parameter is greater than the
second value or parameter, jump to the given label.
D12: IF LESS THAN, JUMP
Example: D12 P01 +Q5 P02 +0 P03 1
∗
If the first value or parameter is less than the
second value or parameter, jump to the given label.
