Chapter 1: Powerlite Sample Application

Powerlite Sample Application which accompanies the Powerlite LabView drivers, consists of some basicfunctionalities required for operating the Powerlite laser. The Powerlite LabView Sample Application isaccessible via the standard function palette after it is installed successfully.

The standard function Palette is as shown below:

Figure 1.1 Powerlite Sample Application in the function palette

This sample application is capable with connecting to the Powerlite laser and also supports the basic operationssuch as changing the mode, setting the parameter values and so forth.

The User Interface of the Powerlite Sample application is as shown below:

Figure 1.2 Powerli te Sample Appli cation User Interface

1.1 RS232 Configuration

Prior to run the sample application; the RS232 communication settings should be properly configured via theSerial Port Configuration Panel. This allows proper communication with the laser machines.By default the following parameter values are set:VISA Resource Name to COM1 Baud Rate to 19200Data Bits to 8 Parity to NoneStop Bits to 1.0 Flow Control to None

The following figure shows the interface of the Serial Port Communication Panel:

1.2 Initial Update

Once the application is started and the communication is established with the laser successfully, the applicationwill query for some important parameter values from the laser, such as Oscillator Voltage, Frequency etc.This process is called as initial update. The values returned by the laser for these parameters will be populatedin appropriate panels of the application window.

1.3 Polling

Once the initial update is done, the application will start to poll for some parameter values.These values change without any user interaction in a predefined interval throughout the life time of theapplication ( Eg: Head Temperatures). The values returned by the laser for these parameters will be used toupdate the corresponding field values in the application window.

1.4 Value Settings

Users are allowed to set values to the parameters of through the application window by simply entering themand clickingon SET button.This facility is provided with the Oscillator Panel, Amplifier Panel and QSwitch Panel.

CautionThe application doesn't prevent any values from going to the laser. For safety requirements, the user needs totake care of the values that he sets via the application.

1.5 Mode Settings

Users are allowed to change the mode of the application at its operation time. STOP, STANDBY, FLASHandQSWITCHmodes can be achieved by clicking on the corresponding button in the Main Control Panel.

Also the Shutter Status could be changed via the Shutter button which is available in the same panel.Both Mode LEDs and Shutter LED will indicate the Mode status and Shutter status respectively.

Figure 1.5 Main Cont rol Panel

1.6 Command Monitoring

The Command monitoring facility available in the application is used to monitor the commands that are sent tothe laser from the application. The display keeps on moving to show the last 11 commands sent to the laser.

Chapter 2: Powerlite LabView Drivers

Powerlite LabView Drivers are special LabView controls to build the Powerlite LabView applications.These drivers free the application developer from needing to know the Powerlite protocols used for the lasercommunication. It also facilitates the common functionalities required by Powerlite LabView application.Once the Powerlite LabView installed successfully; the Powerlite LabView Drivers will be shown in the standardfunction palette as shown below:

Chapter 3: Powerlite LabView Drivers in Application

This section gives some examples to describe as to how the Powerlite LabView Drivers could be integrated inthe Powerlite LabView Applications as its fundamental building blocks.

3.1 Frequency Setting

When the user sets the Frequency via the application, the command required to set the frequency in the laser isenqueued to the command queue which holds the commands to be written to the port.

The following piece taken from the Sample Application's block diagram shows that the 'FreqSetCommand.vi' isused to construct the command required for this by having the frequency value set by the user.

Figure 3.1 Frequency Setting

3.2 Mode LEDs

When the application reads the Mode response sent by the laser, it has to update the Mode LEDs accordingly.The following piece taken from the sample application's block diagram, shows that the -LED.vi's areused to update the Mode LEDs of the application.

Figure 3.2 Mode Setting

3.2 Initial Update Commands

When the application starts up, it has to send some commands to the laser to query some parameter valuessuch as Voltage, Frequency etc in order to update the User Interface. These commands are taken from theInitalUpdateCommands.vi which is a sub module and enqueued to the commands queue.

Figure 3.3 Enqueued Init ial Update Commands
