Tool change
Interface description
Per tool holder/spindle there is one interface for:
● Jobs for preparing and executing the tool change.
● Acknowledgments of the PLC user program
● Feedback from the tool management to the PLC user program
● Job status
End acknowledgment for tool change
A common end acknowledgment (tool change via T command using turret) or separate end
acknowledgment (Txx and M206 in separate blocks, default milling) is possible for "Prepare
tool change" and "Implement tool change." With the appropriate MD setting, the end
acknowledgment for the job to prepare for a tool change permits the NCK preprocessing to
continue.

Signals from tool management [r]
Bit 7
Current magazine number of the tool (INT)
Current location number of the tool (INT)
Target magazine number of the tool (INT)
Target location number of the tool (INT)
Message to the PLC user program: Job active; job specification and job description.
The jobs appear in the toolholder interface (of the spindle) where a tool is to be
exchanged.
All acknowledgments for a job must take place in the interface of the same tool holder (of
the same spindle). Acknowledgment errors should also be reset in this interface.
Message to the PLC user program: Acknowledgment status, error status, map of the
acknowledgment bits.
Selected data from the last intermediate or end acknowledgment is saved. This data is
needed by the PLC firmware for the next acknowledgment to the tool management and is
readable for diagnostic purposes. This data can be used by the user program to restart
after an abort (e.g. reset during a tool change).
