2-28 Function Manual, 08/2005 Edition, 6FC5397-0BP10-0BA0
When the tool management (magazine management) function is activated in the NCK, the
assignment of spindle or revolver and the loading/unloading points are entered in separate
interface DBs (DB71-73)
The triggering and parameter assignment of NCK functions is performed by means of PLC
function calls.
The following function calls are available, for example:
• Position a linear axis or rotary axis
• Position an indexing axis
• Start a prepared asynchronous subprogram (ASUB)
• Read/write NC variables
• Update magazine and tool movement
Some of the above functions are described in their own function documentation.
