Note:
The area of data word 2 of the magazine table is required for the loading line. The tool buffer
may therefore not start before data word 3 (cf. MD 2000).
The following machine data are stored temporarily in DB 146:
DWs relevant for this example:
DW 136: Loading point "Magazine number"
DW 137: Offset loading point 1
DW 138: Offset loading point 2
DW 143: DBVS (3 DBs), DBTL (6 DBs) (package 2 only)
When loading via the operator panel, an empty location to fit the tool size is searched for. The
number of this location is stored in data word DW 5 in DB 146. The user has to ensure that
the magazine is positioned on this location at the actual start of the loading procedure (when
softkey "Acknowledge" is pressed). Otherwise, the error message "Incorrect location at
loading point" appears.
_______
1) Background magazine permissible with SINUMERIK 880/880 GA2 only.
2) Value range for SINUMERIK 840/840C 1...32, 1..16 if tool management is used.
