Control CD or DVD Drive through LabVIEW

Hi All,
I am interested in controlling my PCs internal CD/DVD drive using LabVIEW. I've had a look around the forums and ni website and it seems that external CD drives can be controlled using a PXI card and the SCSI interface.
Searching the LabVIEW help I haven't been able to find any reference to SCSI but I guess the protocol must be implemented somewhere as it can be used with the PXI card I found referenced during my search.
Initially I would like to just open and close the drive - if anyone can offer some pointers in the right direction I would appreciate it.
Also if anyone is familiar with the level of access provided by SCSI maybe I could get a little extra information. For example eventually it would be useful to be able to control the motor speed of the CD turntable independently - is this type of command exposed in SCSI?
Many thanks for your help,
David

Controlling a Siemens S120 drive from LabVIEW over Profinet

Does anyone have any experience using LabVIEW to control a Siemens Sinamatic S120 drive over Profinet. Siemens has a very basic application note which describes using a DLL that they provide to interface with the S120 drive. It is really unclear if all the drive parameters can be controlled using this interface.

Does anyone have any experience using LabView to control a Siemens S120 drive? How difficult is it?

Hello ipbrown,
This looks to be a DLL created by Siemens to be interfaced with LabVIEW. Unfortunately, we will have very limited knowledge of what capabilities this DLL provides. You may need to contact Siemens. Most of the experience I have with PROFINET and LabVIEW involve our PROFINET C Series Module, that can be used to transform a cRIO into a PROFINET slave.

Trying to see DVD drive through DVD sharing. iMac does not see MacBook. DVD sharing is ON.

I have an iMac with a non-working DVD drive and I'm trying to install Snow Leopard from my MacBook's DVD drive. I have turned DVD Sharing ON but the iMac does not see the DVD drive in Finder's Shared Devices. I have tried FireWire, LAN through TimeCapsule and WiFi. Am I missing a step?
The iMac and MacBook are both late 2007 purchases and have 10.5.8.
Thanks for any help.

Two commands you need to type in terminal on the computer that has the dead drive.
Disk sharing like the macbook air does is one of those things that's included in all OS X's on all computers, but that is not enabled. (I think it's cause apple doesn't want to have to support it on more devices that they absolutely have to)
So here's how you enable it.
In your Utilities Folder, open Terminal
copy and paste each line:
sudo -s
*type your password*
defaults write com.apple.NetworkBrowser EnableODiskBrowsing -bool true defaults write
com.apple.NetworkBrowser ODSSupported -bool true
shutdown -r now
Okee dokee... That last command will restart your computer, then you're off to the races!

Simple control of a linear actuator through LabVIEW advice

Hello all,
Was in need of some quick guidance. I purchased a Firgelli PQ12 linear actuator along with their LAC control board. They provide a sample LabVIEW program which I was able to run properly. What I would like to do is create my own LavVIEW program for the motor, basically with two inputs; stroke length, time. I would like for the actuator's stroke to simply extend and retract for a desired time period. What is the best way to go about creating a LabVIEW program for a DC motor? Any tutorials available for this application? Advice? Any help is appreciated.
Thank you!

CD-ROM error on boot after replacing DVD drive -Qosmio F20-574

Ok so I have a Toshiba Qosmio F20/574 and I'm trying to replace the factory DVD drive (TEAC DV-W28E) with a Liteon DS-8A1P (f/w CX12). With or without a DVD drive Im getting a CD-ROM error on boot. The only time I do not get it is when I boot with the factory DVD drive.
Here are the things I've tried...
-Cleared the CMOS
-Removed the bezel to make sure its plug all the way in
-used the EEPROM utility to set the drive to slave.
-tested the drive in another laptop
-unistalled the factory dvd drive through device manager and tried to boot with the new dvd drive
Here are the things I found weird...
- in the BIOS (ACP BIOS 1.30) under Device I/O it shows the Hard Drive and cd drive but its not listed by name, its showing only the IRQ of the master and secondary IDE controller (Built-in HDD Primary IDE (1F0H/IRQ14), CD-ROM Secondary IDE (170H/IRQ15)). This doesnt change, even if I boot without a DVD-Drive.
-There is no BIOS update available for this laptop. This is a Toshiba from Japan and Ive tried using Qosmio F20 BIOS 1.40 from another region but it doesnt work.
-I cant seem to find an update firmware for the Liteon DS-8A1P (CX17)
I cannot think of anything else to try. I really need help! Any ideas?

Hello
your Liteon DS-8A1P (CX17) currently in SLAVE or CABLE SELECT Mode
you must make it as MASTER
Toshiba accepts drives in MASTER settings only
you can not make it by jumper , because there is no jumper inside the drive
you can make it master by:
1-firmware update to the drive to make it MASTER.
2-by soldring pin 47 to pin 45 inside the drive (not recomended).

Is it possible to locate the CD or DVD drive

I was wondering whether it was possible to s it possible to locate the CD or DVD drive with Labview.
My application kinda needs to copy files off the cd drive onto the computer but i don't know how to locate the cd drive
thanks

I'll add some more information about our problem. We would like to detect if a particular drive letter is a CD or DVD drive. The functionality should be similar to the following DriveInfo member in C#.
http://msdn.microsoft.com/en-us/library/system.io.driveinfo.drivetype.aspx
It can tell if a drive letter is a CDrom, Fixed, Network, Removable, Unknown, etc... drive.
I have searched the Advanced File VIs and Function for suitable functions and the GetVolumeData VI is very close (and we could probably detect drives with no free space). However, I wonder if there are any other VIs that can help.
Another example is the following:

Use Labview to control two Picomotor actuators successively through Model 8753 iPico driver

Hello All,
I want to use Labview to control two Picomotor actuators(belong to channel A ,C) successively through Model 8753 iPico driver.Since the example VI's
(Application.vi) from Newport's website just control one actuator at one time, so I copied the example code, thus there are two repetitive sections (see the attachment) in
the while loop structure. The test result was that two Picomotor actuators moved to respective target position circularly. And I found the test was correct when two Picomotor actuators belonged to different address. Can anyone tell why ,what should I do? Any assistance with this matter is greatly appreciated.
Best Regards,

BRox,
I had a look at the examples and obviously all it does is to communicate to the drive through RS232 with a proprietary protocol. With the documentation in the block diagram and the documentation of the protocol it shouldn't be too hard to understand what's going on, but on the other side NewFocus has obviously missed a chance to provide a high level and easy to use API for their product...
I can't dive too deeply into the features of this drive, but before you spend too much time on understanding their command language, you should check with NewFocus, if it is possible at all to meet your requirements with their hardware. The main reason why I doubt that is the slow communication speed provided by RS232. The only way to reach a sinusoidal motion profile of 30 to 70 Hz with this type of communication is running the complete trajectory generation and interpolation onboard. If you have planned to generate the motion profile in LabVIEW and send setpoint commands to the drive this will probably not work.
If the drive provides another command input (e. g. an analog +/- 10 V input for torque or velocity command signals), we can talk about alternative approaches.

Control MAX through labview

Hi,
Is there any way by which I can control and make selections in MAX through labview code?
I need to select driver sessions for IVI classes of instruments. For this it will be good if I can create IVI classes and select driver sessions programatically using labview.
Any take on this?

JoshuaP wrote:
The closest thing to a programmatic API for MAX is the NI System Configuration API, however I don't think that you can currently use it to configure IVI settings.
No, you cant use any existing API to programatically adjust IVI config settings.
However, all of these settings persist in "XML-Hell." With the right file manipulations, regisistry entries and / or details on what, if any, services need to be triggered to update it is THEORETICALLY possible.
Spoiler (Highlight to read)
I Wouldn't try it without serious NI involvement. There is almost certainly a better way to get what you want.

DC motor closed loop control through labview using usb 6008

Hello
i am doing a project in which i want to control the speed of a DC motor (PID control) through labVIEW 2010. I am having a DC motor, a drive unit that regulates the voltage to the motor by getting analog voltage from 0 to 3.3V ( it can be used for both directions) and i also have a NI usb 6008 board. The problem is that i can't feed the usb 6008 with the digital signal from my hall effect speed sensor. Is it posible with this setup to control the motor?? I can also try to use the pulse as analog input and trasform the frequency into rpm's. Then i am thinking of generating an analog signal to feed the motor drive. If you have any further suggestion of a probably better hardware setup would be more than helpfull to me.
Sincerely
Jason Chaloulos

Hello Michael
Thanks for the reply. I came across those topics before and all of them are trying to generate a PWM signal as output i want to use just an analog signal output so timing on the output is not that important i guess. i am struggling on getting the frequency from the digital input signal that my hall effect sensor generates. Since the maximum speed of the motor is 3000 rpm and with my tooth wheel the maximum output frequency of the sensor will be 300Hz which i see its way less than the limitation of my ni board. Is there any tutorial documentation that might help me with this one ? Thank you in advance.
Kind regards
Jason

I'm trying to burn my audiobooks on CDs. Got through three books just fine, then my CD/DVD drive "disappeared." I rebooted and got it back, but iTunes says, even after I un- and re-installed it, that it doesn't have the registries to burn CDs.

I rebooted and got it back, but iTunes says, even after I un- and re-installed it, that it doesn't have the registries to burn CDs. How can I retrieve this capability? My audiobooks are from Audible.

I'd start with the following document, with one modification. At step 12 after typing GEARAspiWDM press the Enter/Return key once prior to clicking OK. (Pressing Return adds a carriage return in the field and is important.)

ITunes and CD/DVD Drive Control

Hi..I can't use my CD/DVD drive for any reason UNLESS iTunes is running at least in the background. It's like iTunes has taken over complete control of my drive. I would like to be able to use the drive for other things (photos, etc.) without having to first run iTunes. Anyone have any ideas about this? Thanks,
Alan

Hi all,
I have a Satellite P30-110. I have tried assigning specific controls to the CD/DVD buttons of my laptop to Winamp but everytime I do it reverts to a default hotkey identifying code.
For example if I want the Play/Pause button to act as a hotkey for the Play button in Winamp and I enter it into the Hotkey setting it comes up as: 0x1770001 but when I click add it reverts to: 0x1000000
Can you tell me why this is or how to stop this from happening.
Thanks!
