help with parametric programming on 840c

[craigh10]

I am trying to program an 840c to use conditional statements. I know how to do this with a fanuc, but am new to programming the siemens control. The following is an example with fanuc program any help converting would be appreciated. thanks in advance.

N005 R500=1

N010 IF R500 EQ 1 GOTO 20
N015 IF R500 GT 1 GOTO 25

N20 M98 P2
N25 M98 P3

I might try using this symbol < , >that might work.

mmachining, never seen <> used in a program

as a quick follow up below is the correct code,


N045 R600=1 (INPUT VARIABLE FOR PART NUMBER)
R601=1 (1= OUTER RING 80 HOLES)
R602=2 (2= INNER RING 60 HOLES)
R603=3 (3= TOP OUTER RING 2 HOLES)
R604=4 (4= TOP INNER RING)
R605=5 (5= BOTTOM OUTER RING)
R606=6 (6= BOTTOM INNER RING)
