9.1.3.4 Maschine data
Not all parameters could be stored in the machine data. Some data are therefore temporarily
stored in data block DB 146:
DB 146
Magazine number of loading/unloading point
DW 136
Offset loading point 1
DW 137
Offset loading point 2
DW 138
DB Tool list (package 2)
DW 143
Loading point "Magazine number"
This data word specifies the number of the magazine where the loading point is located. In a
loading operation with operator guidance, the search for an empty location starts from this
magazine. If no empty location is available here, the search continues in the chained
magazines.
Offset loading point 1/2
These data words specify the difference between actual position and loading point 1/2.
DB Tool list (Package 2)
These data include the number of the first DB of the tool list (Tool list = 3 DBs in parallel).
DB Exchange list (Package 2)
This data word includes the number of the first DB of the exchange list (Exchange list
=3 DBs and list of missing tools = 3 DBs in parallel).
