Access to tool data in the NC program (V.G.WZ..)
V.G.WZ[j]...
The “WZ[j]” variables permit read access to the data of any tool. They are both available with an external tool management system (transparent access) and for use of an internal tool table (<j> then corresponds to the index of the tool (or the tool number) in the tool list [5]).
Write access is only permitted if an internal tool table is used.

V.G.WZ_AKT...
The variables “WZ_AKT”, “T_AKT” and “D_AKT” permit access to the data of the currently selected tool. These variables are available both for an external tool management system and for the use of an internal tool table.
T_AKT | Number of the selected tool | Integer | - | R |
D_AKT | Number of the selected tool compensation record | Integer | - | R |
 | A write access always causes the temporary change of tool data as long as this function is selected. When a new tool is selected (Dxx) or deselected (D0), the changed data are lost. Exception: When an external tool management system is used, the so-called additional tool data (V.G.WZ_AKT.P[i]) is adopted and saved when a new tool is selected or a tool is deselected (P-CHAN-00103). |
