TNC 360 7-8
7 Programming with Q Parameters
7.4 If–Then Operations with Q Parameters
If–Then conditional operations enable the TNC to compare a Q parameter
with another Q parameter or with a numerical value.
Jumps
The jump target is specified in the block through a label number. If the
programmed condition is true, the TNC continues the program at the
specified label; if it is false, the next block is executed.
To jump to another program, you enter a PGM CALL after the block with
the target label (see page 6-8).
Abbreviations used:
IF If
EQU Equals
NE Not equal
GT Greater than
LT Less than
GOTO Go to
Overview
FN9: IF EQUAL, JUMP
e.g. FN9: IF +Q1 EQU +Q3 GOTO LBL 5
If the two values or parameters are equal,
jump to the specified label.
FN10: IF NOT EQUAL, JUMP
e.g. FN10: IF +10 NE –Q5 GOTO LBL 10
If the two parameters or values are not equal,
jump to the specified label.
FN11: IF GREATER THAN, JUMP
e.g. FN11: IF +Q1 GT–10 GOTO LBL 5
If the first value or parameter is greater
than the second value or parameter,
jump to the specified label.
FN12: IF LESS THAN, JUMP
e.g. FN12: IF +Q5 LT +0 GOTO LBL 1
If the first value or parameter is less
than the second value or parameter,
jump to the specified label.
