$TC_MPP3[MagazineNo, LocNo]= Considering adjacent location ON = 1
S
Value = 1: An adjacent location is considered for the location specified
S
Value = 0: No adjacent location is considered for the location specified
S
Value = 0: This must be entered for buffer and load locations.
$TC_MPP4[MagazineNo, LocNo]= Location status (bit mask)
S
Bit 0: Blocked
S
Bit 1: Free/allocated
Default: 2 = Location free
$TC_MPP5[MagazineNo, LocNo]= Location type index
For $TC_MPP1[Magazine no., Location no.]=1 (location type is the magazine
location), the location number is entered here. For other location types, the type
index is incremented:
Example with 2 grippers with location type 3
S
the first gripper has location index 1
S
the second gripper has location index 2
Distances to magazine
$TC_MDP2[MagazineNo, BufferNo.]= Distances between buffer and magazine
A value must be entered for each buffer, at least a zero. The value is not inter-
preted here but is used only for assignment.
$TC_MDP1[MagazineNo, BufferNo.]= Distances between load points and
magazine
One value must be entered for each load location here. It is interpreted when
calculating the location before the load point. Only for "Load point for spindle"
(location 1) is the value not interpreted but used "only" for magazine assign-
ment.
$TC_MLSR[LocationNo of BUFF, LocationNo of spindle]= Assignment be-
tween buffer and spindle.
This enables determination of which buffer, e.g. gripper, may carry out tool
change to the spindle.
In ShopMill the tool change is initiated by a tool–changing cycle. This cycle is
called from the ShopMill cycles where a tool can be programmed.
