Reply with QuoteWhy don't you use from #1-#500?Originally Posted by trangt143
I think from #500 to #1000 are used to read inputs or outputs.
Can't change Macro variables while running program.
I use #740-#750 variables for my program...While running program (auto mode), I can't assign it any number, it comes up "write protected". How do I disable it ?
Thanks

Re: Can't change Macro variables while running program.
Is it fanuc?
You obviously want to use permanent common variables.
Do you observe the same thing for variables in a lower range, say, #500-#600?
You may test in MDI mode also.
Re: Can't change Macro variables while running program.
What model Fanuc is it?
When you display the variables (OFS/SET) [ > ] [ MACRO ] how many variables does the control have?

GE Fanuc Series 16i-T,
I can't change #743=1 while running program, it notes "Write Protect", only I can change it at MDI/EDIT/MPG mode...
Thanks

Re: Can't change Macro variables while running program.
see parm 3290 bit 6
Re: Can't change Macro variables while running program.
I tried set 0 at all bits in #3290, it still not working...

Re: Can't change Macro variables while running program.
Do you mean to say that you can define / redefine these variables in MDI mode but not in AUTO mode?
If ever you come to know the reason, pl do share with us. This is unexpected. Maybe a parameter issue.
If I find out the solution, I will share it...now I am reading parameter manual book...
Re: Can't change Macro variables while running program.
Just curious, what was #3290 set to before you set it to all 0's?
only MCM, I change 1 to 0...
Re: Can't change Macro variables while running program.
MCM set 0, and need to turn off the power.... turn it on again, it is working now....
thanks everyone for helping...
Re: Can't change Macro variables while running program.
Thank you for sharing information.
