GOTO Statement in Program

[dgriffiths]

I would like to put a GOTO statement at the end of a program to make it jump back to a previous line number and loop the program. I have never used GOTO statements in my programs and I am not sure of the format to use and what is required to make it work. I tried adding GOTO N20 at the end of my program and it is not working. I am not finding anything in my Fanuc Manual. The control is a Fanuc 31i.

Just put

 

GOTO20

 

No space, no N. Also, make sure you only have ONE N20 in your program.

I would do a while do loop.

 

Something like so.

 

N20

#100 = #100 + 1

BODY OF PROGRAM

------

------

WHILE [#100GT20] DO1

GOTO20

END1

M30

 

You could also write it this way.

 

N20 START OF PROGRAM

#100 = #100 + #101(MATH EQUATION)

#101 = 1 (ADDITION VALUE FOR EQUATION)

#102 = 20 (AMOUNT TO STOP PROGRAM AT)

BODY OF PROGRAM

------

------

IF[#100EQ#102]GOTO30

GOTO20

N30M30

 

 

This should allow you to run the program 20 times then finish.

Thank you everybody. I will give it a go.
