9.6 If-then decisions with Q parameters
Programming if-then decisions
Press the JUMP soft key to call the if-then conditions. The TNC then
displays the following soft keys:
Abbreviations used:
There are three possibilities for entering the jump address:
 Label number, selectable via LBL NUMBER soft key
 Label name, selectable via LBL NAME soft key
 String parameter, selectable via QS soft key
Function Soft key
FN 9: IF EQUAL, JUMP
Example: FN 9: IF +Q1 EQU +Q3 GOTO LBL “SPCAN25“
If the two values or parameters are equal, jump to the
given label
FN 10: IF UNEQUAL, JUMP
Example: FN 10: IF +10 NE –Q5 GOTO LBL 10
If the two values or parameters are not equal, jump to
the given label.
FN 11: IF GREATER, JUMP
Example: FN 11: IF+Q1 GT+10 GOTO LBL QS5
If the first value or parameter is greater than the
second, jump to the given label.
FN 12: IF LESS, JUMP
Example: FN 12: IF+Q5 LT+0 GOTO LBL “ANYNAME“
If the first value or parameter is less than the second,
jump to the given label.
IF :If
EQU : Equal to
