### A Note on V42R Compatibility

Calibrations for two rotary tables are saved in both PC-DMIS version 4.2 (V42R) and PC-DMIS version 4.3 (V43R). However, V42R only has dual rotary table support and not stacked rotary table support.

Only one single rotary table angle is stored in a V42R part program and the same angle is used in the part program for both rotary tables. On the other hand, V43R has stacked rotary capability and saves both V and W table angles to part programs.

If a V42R program is read into V43R then the single rotary table angle copied to both V and W table angles in order that a part program intended for use dual rotary table will work regardless of the settings of the Rotary Table Setup dialog box.

If a V43R program is saved in V42R format then one of the angles will be lost. PCDMIS will inspect the rotary table setup and if dual rotary and the V table is selected then the V angle is saved, otherwise the W angle is saved. Thus, a part program written for dual rotary can be exported to V42R if required.

If a part program is written in V43R for use on dual rotary with different W and V angles and it is required to export it to V42R then it should be exported to two separate part programs:

- First, with the rotary table settings set to the W table.

- Second, with the settings set to the V table.
