Tool State - Sinumerik 840D sl

 good morning Neil,  for "tool was in use" I think it may content in the SINUMERIK tool management function, Which normally customized by machine builder.  I suggest you to contact OEM--DMG Mori, or Google SINUMERIK 840D SL Programming Guide Advanced

DMG Mori - DMU 50

Where can read the tool state that are in the tool pages?

I need to read if the tool is marked or not in the "tool was in use" field and then make a decision to measure the tool or not with the BLUM laser tool setter in an unmanned / automated operation.

Thx,

Neil

 Very good and professional answer , Steve, I don't know, for Neil is it too complex to deal with system variables and logical operations . so I suggest him to contact OEM, or using Programming Guide Advanced, here i can attach Tool Management Doc

I suggest you use the “measure” bit in the tool status, which is $TC_TP8.  This link should go to the section in the Tool Management document that covers tool data.

You need the internal tool number as an index.  For the current active tool, this is $P_TOOLNO.  You can use B_AND and B_OR to check and set the measure bit as needed.
