### CWSPresent

This setting is responsible for passing the Chromatic Whitelight Sensor (CWS) commands to the Firmware Distributed Controller (FDC).

Note: The CWS is a sensor used in vision machines. Topographic, Profile or Roughness measurements are performed in confocal distance measurements. In this process, white light is focused on the surface of the measurement object using an optic with a pronounced chromatic aberration. The reflected light is maximized for the wavelength for focussing of the target surface. The spectrum of the reflected light shows a pronounced peak allowing the spectral position to determine the distance to the surface.

Entry Name: CWSPresent

Entry Type: The default value is False and no CWS command will be sent to the FDC. Setting the value to True will allow the FDC to handle the CWS.

In order to use CWS with FDC, the following registry settings are necessary:

- (FDC) CWSPresent = True

- (MSI) Laser_Type = 2

CAUTION: Please do not change this setting. Refer to the Machine Interface Installation Manual (MIIM) for detailed information.
