Tool life quantities

Tool life, Tool life distance

With every programmed T<i> or #TOOL PREP and when P-CHAN-00076 is set, the complete tool ID, the tool life and the tool life distance are sent automatically from the CNC to the PLC and are stored there.

The following data is transferred from the CNC to the PLC:

CNC_TOOL_DATA_IN (Tool life data sent from CNC)

tool_id : CNC_TOOL_ID; (Tool id from CNC)

time_used : LREAL; (Usage time of tool in seconds)

dist_used : LREAL; (Usage distance in mm)
