I've never seen it on FANUC. Instead, what I have done in the past is to only display it as a function of "GO/NO GO" type of thing. You can prompt the message depending on certain conditions. If the measured value is in range you prompt a message:
#3006=1(#520-VALUE-IN-TOLERANCE)
Then, if its out of tolerance you can jump it to:
#3006=2(#520-OUT-OF-TOLERANCE) .... or you can trigger a machine alarm instead:
#3000=1(OUT-OF-TOLERANCE)
If you're needing this because you need to verify results or track results, the only other way I can think of is to use a DPRINT macro and have the machine output the results to a file or printer.
It's just a part..... cutter still goes round and round....
