9.3.1 Relocating, unloading, loading tool, positioning magazine
Tool and magazine movements
Per loading point there is one interface for:
● Jobsfor loading, unloading and relocating a tool (MVTOOL) and for magazine positioning
(POSM).
Message to the PLC user program:
– Job active
– Job specification
– Job description
The
jobs appear on the interface of the loading point from which the tool is to be exchanged.
● Acknowledgments of the PLC user program
All acknowledgments for a job must take place in the interface of the same loading point.
Acknowledgment errors should also be reset in this interface.
● Feedback signal from the tool management to the PLC user program
Message to the PLC user program:
– Status of acknowledgment
– Error status
– Map of the acknowledgment bits
● Job status
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).
All acknowledgments for a job must take place in the interface of the same loading point.
