in standard Fanuc Macro B, what variables are 'local' and 'global'?

 

Working on a post with sub program support and need touse some local and some global.

 

Thanks,

#1-#33 Local

#100-#149 (or #199) & #500-#531 (or #999) Common

 

the (or ---) are optional and may not be available in every machine

If I understand what you're askin

 

#1-#33 are local variables & change from sub to sub.

 

#100-#149 are global, but loose their value when you shut down a machine.

 

#500-#531 are global & can hold their value even when the machine is shout down.

#1-#33 -- local

#100-#149(optional to #199) common (volatile)

#500-#531(optional to #999) common (non-volatile)

Local variables are variable numbers #1 to #33 and are typically used as temporary use variables for subprograms.

 

Local variable example:

G65 P9000 X10 Y5 Z1 A2.5 B3.6

 

When this block is executed, these values are assigned to local variables before program 9000 begins.

Program 9000 can then read these values in these variables:

#24=10 (X)

#25=5 (Y)

#26=1 (Z)

#1=2.5 (A)

#2=3.6 (

 

Common variables are variable numbers #100 to #999 .

Unlike local variables, Common variables can be used and set by any program.

These variables are also retained on exit.

 

System variables are variables numbers #1000 to #5999. System variables are used by the CNC to store internal values needed for operation.

These values are things like tool length offsets, diameter offsets and machine positions.

excellent!!

 

I knew I could get the answer quick here.

 

Thanks.
