Fanuc Macro Question

[Karl@CP PISTONS]

Does the fanuc macro language have a MOD Division function? If not anybody have any ideas how I can determine if a passed variable is an even or an odd number? The passed value is always going to be between 1 and 8 inclusive.

 

Thanks

I bet there are at least a dozen ways to do it.

 

If it's always going to be an integer from 1 through 8, you could always just test for 2, 4, 6, and 8.

 

I have a big book on Macro at home I can check for that MOD function later.

Yes, I just learned to use this the other day. I had to write a macro that changed a range of tool offsets but skipped ones ending in 1 or 7.

 

Since you already know about the MOD function without knowing if it's in Macro be, I'm assuming you know how it works. Here's the format.

 

#101= 17

#102= #101 MOD 10 (result is 7)

 

Here's how I'd try to use it.

 

#100= (PASSED VALUE)

IF [[[#100 / 2] MOD 10] EQ .5] GOTO 1

GOTO 2 (if not, go to N2)

N1 (#100 IS ODD)

N2 (#100 IS EVEN)

 

This has no provision for a zero result, but you could add that later if you need it.

 

Hope that helps, let us know what works!

Matt, The book I have ( FANUC custom macros ) does not even mention MOD division. I did not want to have a confusing program as it's bad enough already.That is why I did not want to test for every value 1-8

 

kunfuzed, Yes I do know how the MOD function works and thanks for the format example.

 

Here is what I ended up with:

 

IF [#101 MOD 2] = 0 GOTO15

( ODD OFFSET NUMBERS )

#[6982+[[#101 + #137]*20]] = #144

( P1,P3,P5,P7,P9,P11,P13,P15 - Y )

#[6981+[[#101 + #137]*20]] = #129

( P1,P3,P5,P7,P9,P11,P13,P15 - X )

 

GOTO16

 

N15

( EVEN OFFSET NUMBERS )

#[6982+[[#101 + #137]*20]] = #143

( P2,P4,P6,P8.P10,P12,P14,P16 - Y )

#[6981+[[#101 + #137]*20]] = #129

( P2,P4,P6,P8.P10,P12,P14,P16 - X )

 

N16

 

I have not had any open time on the machine to test it but it looks good on paper

 

Thanks to both of you for the info.

I finally got time on the machine to test the code and I needed only one correction:

 

was: IF [#101 MOD 2] = 0 GOTO15

is: IF [[#101 MOD 2] EQ 0] GOTO15

 

Thanks for the inspiration gentlemen

Lol, I sure was taking the long route by doing MOD 10 and then dividing by two, when you could just cut to the chase and do MOD 2.

 

What book do you have? I've got "Fanuc CNC Custom Macros" by Peter Smid. Pretty good topic coverage, also covers MOD.

 

Glad you got it!

[Karl@CP PISTONS]

I have the same book but I did not find anything on the mod division in the index? I must have just missed it.

All I need is the final testing of running all 8 parts on both pallets and it will be done. What a relief it will be to finally take a project OFF my plate.

 

Thanks again
