7 Programming with Q Parameters 7.4 If–Then Operations with Q Parameters Jumps Overview 7-8 If–Then conditional operations enable the TNC to compare a Q parameter with another Q parameter or with a numerical value. 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 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. TNC 360
7 Programming with Q Parameters 7.4 If–Then Operations with Q Parameters TNC 360 Unconditional jumps Unconditional jumps are jumps which are always executed because the condition is always true. Example: FN 9: IF +10 EQU +10 GOTO LBL1 Since it is always true that 10=10, the jump will always be executed. Program example When Q5 becomes negative, a jump to program 100 will occur. . . . 5 FN0: Q5 = +10 ................................................... Assign value (such as 10) to parameter Q5 . . . 9 FN 2: Q5 = +Q5–+12 ......................................... Reduce the value of Q5 10 FN 12: IF +Q5 LT +0 GOTO LBL 5 ..................... If +Q5 is less than 0, jump to label 5 . . . 15 LBL 5 .................................................................. Label 5 16 PGM CALL 100 ................................................... Jump to program 100 . . . 7-9
