Hello to all,

I'am having a problem with my KIWA EXCEL mill with FANUC OM-C.
This is a arm type toolchanger with a 24 tool caroussel. So when the tool changes from T1 to T2, T1 goes in the pot where T2 was.
My problem is that sometimes the Diagnostics of the tool does not change so my tools get mixed up even though the tool did fisically change.
So when changing from T1 to T2 the diagnostics stays the same. I have had this a couple of times with a crash folowing. So all my trust in this machine is all lost. I don't know where I should be looking to figure this out. I just don't know what makes the diagnostic change. Is it a sensor?

Please help me. Thanks
