Karel Instruction Help

Have a Fanuc LR mate 200id with a 30i B Controller and want to modify a Karel program statement

That seems more like TP, not Karel ..

to add several OR statements with integer values after the <4 value. Can I just insert <4 OR 3 OR 5 OR 8 OR etc....Logic is as follows:
• Line 67: IF (RI[2:HxBlnkGrip_CLSD]=ON AND R[1:Part Number]<4 Then;
• Line 68: CALL M_LOAD_CYCLE ;
• Line 69: JMP LBL[4] ;

No, that won't work. You'll have to compare each option with R[1:Part Number], or come up with a single statement that lets you do what you want.

Looks like you basically need to check whether R[1:Part Number] < 8, correct? You don't have 6 or 7 in there, but since you include 8, all the others will be smaller than that anyway.

Yep, you could do that. The code would look like this:

: IF (RI[1:HxBlnkGrip_CLSD] AND R[1:Part Number]<4 OR R[1:Part Number]=7), CALL M_LOAD_CYCLE  ;

Be aware of order of operations though. Numerical comparisons have a higher precedence than logical comparators, and the 'AND' comparator has a higher order than the 'OR' comparator.

You could expand the IF statement to encompess the conditions you want. A mixed logic IF statement can support up to 20 items in it.

Otherwise you could break up the IF statement into multiple if statements.

For example:

: IF (RI[1:HxBlnkGrip_CLSD] AND R[1:Part Number]<4), JMP LBL[5] ;
    : IF (R[1:Part Number]=7), JMP LBL[5] ;
    : IF (R[1:Part Number]=11), JMP LBL[5] ;
    : IF (R[1:Part Number]=7=25), JMP LBL[5] ;
    : !None of the above are true... ;
    : JMP LBL[10] ;
    :  ;
    : LBL[5:True] ;
    : CALL M_LOAD_CYCLE  ;
    : LBL[10:End] ;
