If you just want to check to see if it falls within an upper and lower limit then you can program this yourself and add it to the tool change cycle.. I also think that the Siemens tool management system will monitor tool wear. Let us know a bit more and I can narrow down your options. Pee

Try to put at the beginning of the program: %_N_CHECK_OFFSET_SPF ;$PATH=/_N_CUS_DIR ... and at the very end: RET Good luck Nit

Dear Nit

I modify subroutine to correct my mistake.

But machine problem with (level of nesting) .

Could you please help me about define macro element and guidance to me other way

for define subroutine and call in main program.

For example:

m99 (tool_nom,tool_offset,limit) use in main program.

Best regards.

It would be easier if you simply rename it as Cyclexxx (see what number is available), put it in Custom Cycle directory or Machine Builder directory and call it with Cyclexxx(49,117,1). Good luck Nit
