#### Execute Mode Tab

BASICSCAN dialog box - Execute Mode tab

The execute modes available in the Execute Mode tab are the following:

- NORMAL

- RE-LEARN

- DEFINED

See "Exec Controls area" in "Execution Tab" for more information on the Normal, Re-learn, and Defined modes.

- FEATURE – This execute mode is available only for Analog Probe Heads. When this is selected, PC-DMIS uses the built-in High Speed scanning capability of the controller to execute a scan.

Example: If you selected a Circle scan, PC-DMIS will use a corresponding Circle scanning command in the controller and pass on the parameters to the controller to execute. In this case, PC-DMIS does not control execution of the scans.

The FEATURE execute mode also allows you to use the following check boxes to further customize how PC-DMIS Basic scans are done using this mode. Note that these check boxes only work with controllers using the Leitz interfaces:

Use HSSDAT – If you select this check box, PC-DMIS sends a distinct set of points defining the feature measurement path to the controller. If you don't select this check box, PC-DMIS will send the feature specific parameters to the controller.

Use Start/End delay points – You must also select the Use HSSDAT check box to use this functionality. If you select this check box, PC-DMIS takes the points sent to the controller and discards those points taken during acceleration and deceleration of the probe during the scan, thereby filtering out fluctuation during these machine speed changes and improving the overall accuracy of the scan.

Warning: Be aware that when using Start/End delay points the machine will over travel the defined start angle and end angle by the distance it takes to arrive at full speed when starting the scan. If you aren't careful this could cause a probe crash if there is an obstruction on the circle feature.
