Access to tool data in the NC program (V.G.WZ..)
V.G.WZ[j]... The "V.G.WZ[j]" variables enable Read access to the data of any tool in the external tool management (transparent access; j corresponds to the tool number).
V.G.WZ[j].R | Radius of the tool | R |
|---|---|---|
V.G.WZ[j].L | Length of the tool | R |
V.G.WZ[j].P[i] | Parameter of the tool | R |
V.G.WZ[j].V[i] | Axis offsets of the tool | R |
V.G.WZ[j].ME | Dimension unit of the tool data | R |
V.G.WZ[j].OK | Valid flag of the tool | R |
V.G.WZ[j].SPDL_AX_NR | Logical axis number of the assigned spindle | R |
V.G.WZ[j].KIN_PARAM[i] | Kinematics parameters of the tool | R |
V.G.WZ[j].KIN_ID | Kinematics ID of the tool | R |
V.G.WZ[j].TYPE | Tool type | R |
V.G.WZ[j].SRK_ID | Cutting position in the case of a turning tool | R |
V.G.WZ[j].S_MIN_SPEED | Minimum speed (Tool dynamic data) | R |
V.G.WZ[j].S_MAX_SPEED | Maximum speed (Tool dynamic data) | R |
V.G.WZ[j].S_MAX_ACC | Maximum acceleration (Tool dynamic data) | R |
V.G.WZ[j].SISTER_VALID | Valid flag of the sister tool (TOOL-ID) | R |
V.G.WZ[j].SISTER | Number of the valid sister tool | R |
V.G.WZ[j].VARIANT_VALID | Valid flag of the variant tool (TOOL-ID) | R |
V.G.WZ[j].VARIANT | Number of the valid variant tool | R |
V.G.WZ_AKT... The "WZ_AKT" variables as well as "T_AKT" and "D_AKT" enable access to data of the currently selected tool.
V.G.T_AKT | Number of the selected tool | R |
V.G.D_AKT | Number of the selected tool record | R |
 | Write access results in temporary modification of the tool's data, if it is selected. The modified data is lost when a new tool is selected (Dxx) or when the tool is cancelled (D0).ExceptionWhen external tool management is used, the so-called additional tool parameters (V.G.WZ_AKT.P[i]) are accepted and saved when a new tool is selected or when a tool is cancelled. |
V.G.WZ_AKT.R | Radius of the selected tool | R/W |
|---|---|---|
V.G.WZ_AKT.L | Length of the selected tool | R/W |
V.G.WZ_AKT.P[i] | Parameters of the selected tool | R/W |
V.G.WZ_AKT.V[i] | Axis offset of the selected tool | R/W |
V.G.WZ_AKT.ME | Unit of measure of the selected tool | R |
V.G.WZ_AKT.OK | Valid flag of the selected tool | R |
V.G.WZ_AKT.SPDL_AX_NR | Logical axis number of the assigned spindle | R |
V.G.WZ_AKT.KIN_PARAM[i] | Kinematics parameters of the selected tool; note on write access: the value must be programmed in internal units! | R/W |
V.G.WZ_AKT.KIN_ID | Kinematics ID of the selected tool | R |
V.G.WZ_AKT.TYPE | Tool type of the selected tool | R |
V.G.WZ_AKT.SRK_ID | Cutting position of the selected turning tool | R |
V.G.WZ_AKT.S_MIN_SPEED | Minimum speed (Tool dynamic data) | R |
V.G.WZ_AKT.S_MAX_SPEED | Maximum speed (Tool dynamic data) | R |
V.G.WZ_AKT.S_MAX_ACC | Maximum acceleration (Tool dynamic data) | R |
V.G.WZ_AKT.SISTER_VALID | Valid flag of the sister tool (TOOL-ID) | R |
V.G.WZ_AKT.SISTER | Number of the valid sister tool | R |
V.G.WZ_AKT.VARIANT_VALID | Valid flag of the variant tool (TOOL-ID) | R |
V.G.WZ_AKT.VARIANT | Number of the valid variant tool | R |
V.G.WZ_AKT.WEAR_RADIUS | Radius wear at radius compensation (OTC) | R |
V.G.WZ_AKT.WEAR[i] | Wear in axis <i> at length compensation (OTC) | R |
V.G.WZ_AKT.WEAR_CONST | Wear constant (OTC) | R/W |
As an alternative to V.G.WZ_AKT.P[i], the following variable can also be used to access the additional tool parameters. It is available only when using external tool management:
V.G.WZ_INFO[i]Programming example NC program with tool requesting
In the following example, various tools are inserted by the CNC and the data is requested from the external tool management. The request always contains the tool parameters of the tool that was last active for return transfer of updated values to the PLC.
