Controllers: Fanuc 18iMB.
I have a lot of programs that I would like to be able to run on 2 similar but not identical machines. Rather than writing 2 programs, is it possible to maybe set a parameter on machine A to "1" & machine B to "0" then have the code read the parameter status? If so, what parameter number? and how do I call it in a program?

example of logic would be.

If parameter *** = 1 goto block N100
If parameter *** = 0 goto block N120

I hope this makes sense to someone.
Any suggestions would be greatly appreciated.
Thank you.
Kenn.

G10 allows you to write parameters but I don't think there's any 'code' to read them.
'checking the machine' type questions have come up a few times in the past. one solution is if the machines have macro you can pre-set a variable to a unique number for each machine then read that variable at the top of the program.

Hi Fordav11,

I have never used macro, & I don't have a lot of programming experience. If it's available I will try to use it.
Does that mean that the preset variable is stored permanently in the controller?
Thank you

yes its permanent if you use the variable #'s that don't clear when the machine is powered off.
to check the variable using variable #500....

IF #500 =0 GOTO N100
IF #500 =1 GOTO N120

you can check for the existence of macro.
in MDI type #100 = 1 EOB then press INSERT then start. if you don't get an alarm then you have Macro B.

Thanks a lot Fordav11.
Really appreciate your help. I will check it out.

also check for macro A just in case....
in MDI ....
G65 H01 P#500 Q1 EOB then press INSERT then start

[fxken]

Just checked
#100=1 EOB. no alarm. Looks like I got macro B. I will check for macro A later. Looks like I've got some work to do.
Thanks again for your help.

and cycle start too?
you can find the macro variable list on the offset page then page right until it comes up.
#100 should be 1 if it worked.
