Problem change Fanuc 0-M display cordinates

Hi,
i was wondering if anyone in here would know, what lines to change to get our 0-M Machines to show the cordinates, for acutel tool depth
i have the cordinates for Too-go while drilling and such, but i cannot see the depth, only the machines cordinates

i got a machine with the 11M control, and it shows the actual depth

all in all, i want is to see what hight the tool is at, insted of the machine position, as an example, when running deep cuts, i would like to know if i´m 7 or 7.5 mm in depth at the actual position. Without having to calculate it myself by finding the tool offset.

I really hope this is possible, because i really miss this option to make sure the depth is right.

Thanks for looking at my problem.
Thanks in advance.

Regards Peter
