LABVIEW DRIVER

7.1. PC-BEAMAGE LABVIEW

EXAMPLE VI’S

The PC-Beamage Software can be controlled from LabVIEW using the VI Library supplied by Gentec-EO.
They are individual VIs to implement each of the supported control and measurement functions. There is
also  an  example  VI  that  demonstrates  how  to  use  the  individual  VIs  to  build  a  standalone  LabVIEW
application.  Before  using  the  VIs,  the  PC-Beamage  Software  must  be  running,  and  the  LabVIEW  Pipe
must be opened.

The VIs can be grouped into 6 basic categories.

1.  Connection VIs
2.  Control  VIs
3.  Measurement VIs
4.  Display VIs
5.  Activation VIs
6.  Miscellaneous VIs

7.1.1. Connection VIs



Verify DLL.

This VI checks to ensure the required DLL file is present in the directory in which the LabVIEW VIs are
located.



Connect to PC Beamage.

This VI connects to the LabVIEW pipeline opened by the PC-Beamage software.



Disconnect from PC Beamage.

This VI disconnects from the LabVIEW pipeline opened by the PC-Beamage software.

7.1.2. Control VIs



Control Stop Capture.

This VI stops the capture from the PC-Beamage software and the Beamage USB Camera. Running this
VI is the same as pressing the Stop Capture button in the software.



Control Start Capture.

This VI starts the capture from the PC-Beamage software and the Beamage USB Camera. Running this
VI is the same as pressing the Start Capture button in the software.

The following Control VIs are Main Controls.



Control 4 Sigma.

This VI sets the Beam Diameter Definition Control in the PC-Beamage Software. Running this VI is the
same as pressing the selecting the 4 Sigma (ISO) control in the software.



Control FWHM.

This VI sets the Beam Diameter Definition Control in the PC-Beamage Software. Running this VI is the
same as pressing the selecting the FWHM control in the software.
