Status list
Status = 1:
The WZV operation is completed (loading/unloading/reloading, prepare change, change).
The parameters "NewToolMag", "NewToolLoc", "OldToolMag", "OldToolLoc" of the FC 8
block are to be parameterized to the actual positions of the tools involved. Except in the case
of preparing change these are normally the specified target position of the tools of the
associated WZV interface, see also "Explanations of the formal parameters".

example, be positioned in a buffer (gripper). In some cases, the target (magazine,
location) of the old tool has been moved to the toolchange position after placement of the
new tool in a buffer. However, the old tool still remains in the spindle. The preparations
for a tool change are thus complete. After this acknowledgment, the "Change" command
can be received. The positions in parameters "NewToolMag", "NewToolLoc",
"OldToolMag" and "OldToolLoc" correspond to the current tool positions.

The tool-change operation is thus completed.
