MyRIO Low Level VIs

Good Afternoon,
I am trying to use the low level VIs with a myRIO. Here is the block diagram with everything stripped out except the low level digital output blocks (the timing has also been modified to create one pulse every two seconds):
I know that there are easier ways to do this, but I am trying to learn how to use the low level VIs. When I run the code, everything seems to work properly (the debugger proceeds normally with no errors), but the output just stays at 3.9 volts.
Can anyone tell me what I am doing wrong? The project is attached (zipped).
Thank you,
John

Low Level VI Test.zip ‏62 KB

This is almost exactly like the VI shown in this video (I could not make it exactly - my version of LabVIEW must be different).

The VI runs with no errors, but it always reads high from the input.

USB Camera and Low level VIs

Hello all,
I am beginner in LabView and I am seeking help for the following:
I need to adapt a vi using a regular (analog) camera so to start using a USB camera instead. When I viewed the block diagram (which is really complicated for me) I noticed that the original programmer used the low level IMAQ VI's (e.g. IMAQ intil.vi and IMAQ configure Buffer.vi) to communicate, control and acquire images from the camera. Now, I am really confused, does these VIs work with all cameras? If not can I replace them with the IMAQ USB VIs'? How would this affect the other VIs that depends on the out come of the replaced ones? Finally, I would be glad if anyone can point out things to read so to acquire more knowledge about this subject?
I know I asked much but really I want to learn these things as fast as possible
Best Regards
Mohammed

Hello TomBaum,
First, thanks for responding, really appreciate it.
Sorry that I cant send the Vi itself yet I have attached a picture of the part
that I want to modify (red rectangle).
All I want to do is using USB camera instead of the one used now! so does
these low level VIs work with the USB camera
or I should use the USB camera VIs which will mean that i will end up with many
broken wires since low-level VIs has
different number on inputs that the USB camera VIs
Hope this can give you an idea.
P.S. in case you will wonder about the sequence structure; it is only the
camera setting that I am interested and it is the one shown in the
structure
All the broken wires in the picture are going into a very larg while loop with
many other VIs.

Low Level VI for ELVIS

Where can I get the low level VIs for ELVIS functionalities not currently exposed in LabView eg for Bode Analyzer, Arbitrary WaveForm Generator

Hi Adnaan,
The lower level VI's are just as you list: DMM, FGEN, etc. I'm sorry the Bode Analyzer low level's are not available.
It looks like all of the controls for the BodeAnalyzer can be accessed from the block diagram, is this not the level of programatic control that you need?
The Express VI link was included in case you we're interested in how to create these.
Have a great weekend!

High level and low level grabs

Hi, I'm looking at different acquisition options. Fast acquisition is a priority as is fast processing. I'm a little confused on high level versus low level. Is there any benefit to which one is used? Or is it 6 one way and 1/2 a dozen the other. Thanks

If you feel comfortable using the Low Level functions I would personally recommend using them instead of the High Level. Bruce's answer is correct, high level will call low level with standard options selected. If you think of ways to improve the speed of your code, you may want to use low level, my reason is because high level VIs will actually be a function call calling other functions, which introduces a minimum delay, instead, if you use low level you are directly calling the functions for acquisition so there is kind of a small time saving if you think of it as acquisition wise.
Also, the high level VIs if you check their block diagram it has more structures for error checking, session ID checking, etc., so with low level you have direct control over the acquisitio
n from your main program without introducing innecessary structures or functions.

Low level control of serial port?

Hi there,
We're using LabVIEW 7.1 and I would like to control some low level aspects of the serial port (I'm having a LOT of difficulty connecting to an ABU93 autoburette). Is there a way to set the DTR, DTS RTS and CTS in LabVIEW 7.1? Is this controllable through VISA?
Thanks for any help,
Russ

The serial lines cannot be adressed using the Configure serial port VI. You need to dig a little deeper, and access the modem property node.
See the attached vi.

Unable to create a folder in lower levels of root folder

It appears to me I cannot create a new folder in the lower levels of root folder. Currently, I have to create a new folder right below root folder and then drag it to lower level folder. Why I can't do it in one go. Thanks!

Hi Ray. That is normal behavior for Snow Leopard now. The OS wants to reserve the root level for itself. Also, folders you create at the root level may not accurately reflect the correct permissions.
You want to try to keep all your files/folders in your Home (User) folder. That way all your documents remain portable when you move to another Mac or migrate your data back after an Erase & Install. If your docs are scattered all over the drive there is a chance some stuff will not get transferred during a move. So try to keep everything inside your Home folder.
If you have to place a new folder at the root level, try creating the folder on your Desktop, then dragging it to the root level.

Issue in determining Low level codes

Hi Gurus,
We are having an issue running heuristics when running along with Temporary low level codes. We are in SCM 7.0 environment.
The SNP Heuristics jobs are failing with this message "Low-level code
not available for product XXXXXXX at location XXXX
Job cancelled after system exception ERROR_MESSAGE"
Also, the message in the job log for the product in was flagged for deletion and I am not too sure why is this being picked up for processing and then failing?
I tried using SDP relevance as '1' for the product flagged for deletion for testing purposes and then the program is not considering this SKU, but stopping at another SKU and also that SKU is flagged for deletion. But the flip side of using SDP relevance is that that setting is at global level andmay have issues where the SKU is active.
I have couple questions:
1) Is there a way for the program to skip the code which has an error and move forward instead of failing the job? and provide a spool with error codes.Also, to provide the LLC number for all the correct SKU's instead of failing at that point and not generating the LLC's?
2) Why is the program also considering the codes which are flagged for deletion which should not be the case?
Also, I tried another way of maintaining the codes in thevariant which are not flagged for deletion and tried running heuristics in the background but failed at a point and it gave a message stating Low-level code not available for product XXXXXXX at location XXXX, Job cancelled after system exception ERROR_MESSAGE
But the product which was displayed in the job log is an active SKU. I am not too sure why the job failed with this error?
I tried running that individual SKU in the background including the temporary determination of LLC, it was successful. I am not too sure why it failed when it was a part of selection?
Any suggestions, would really help us a lot.
Thanks and regards,
Murali

Hi Datta - Thanks for the replies. I was able to have a workaround by using selection profiles excluding the Procurement type 'P' and it worked.
At our client, whenever a product is made 'non-X0' in ECC, procurement type is set to 'P' and by excluding that piece in the variant I was able to continue with my processing.
But still, don't you think the products which are flagged for deletion shouldn't be picked up heuristics?
Thanks and regards,
Murali

Collective Planned orders Scheduling for lower level orders with reference to the Superior order

Hi All,
Collective planned order scheduling.
I have been trying to reschedule the superior planned order and i was expecting the lower level planned orders to reschedule based on the superior planned order.
My problem is
when i try to reschedule the superior planned order the system is not rescheduling the lower level planned orders.
For example if i change the basic finish date of superior planned order as 30/09/2014 and reschedule the planned order it is only scheduling the header planned order and the lower level planned order is not scheduling.
Could some one tell me why this is not happenning at planned order level.
As the rescheduling of collective order will work at production order level but for some reason it is not happening at planned order level(as there is no option available to do so).
Please give your thoughts on this asap.
Mahee.

Hello Mahee
Please observe that your system is working as designed. Planned orders are scheduled independently, even when they are part of a network/collective order. Note 152319 explains the planned order scheduling in detail and it provides the following information:
* No scheduling of overall networks is executed although a directly manufactured component is assigned.
Note that no scheduling of the overall network is executed for planned orders. For the components requirements dates are determined. In order to cover them, planned orders are created in the next MRP run. Since the requirements are not managed using the exact time, the results of the planned order scheduling and of a scheduling of the overall network of the converted collective order can differ.

Difference between Low level and Normal IMAQ ?

There are two options in IMAQ palette a low level and a normal one. Both have the same function names and the same icons the only difference being the balck and white icon of low level functions and colored icons of the normal functions. What is the difference between these two and what is the need of making a low level palette of functions ?

How to disable Wifi and Network access in low level setting for security ?

Hi
New to here
One of our final customer bought imac last months. OS 10.9, SN is c02*******J4i
Since they are security printing, all the necessary ports accessing to outisdes need to be disabled in low level setting(not the ons just like turn on and off ).
The ports including USB storage, Network and WIFI.
I googled and found the following
Open the /System/Library/Extensions folder.
To remove support for USB mass storage devices, drag the following file to the Trash: IOUSBMassStorageClass.kext
Open Terminal and enter the following command: $ sudo touch /System/Library/Extensions The touch command changes the modified date of the /System/Library/Extensions folder. When the folder has a new modified date, the Extension cache files (located in /System/Library/) are deleted and rebuilt by Mac OS X.
Choose Finder > Secure Empty Trash to delete the file.
Restart the system.
I want to confirm this before sending to final user. Since I didn't have mac on hand, just wonder whether there are similar kext files for network and wifi to remove.
Just like step 2 described.
I would like customer to backup these files before permanently removed.
Many thanks
Kevin

Is it possible to disable Internet access point and WAP as when I use WiFi some connections to WAP server of my provider are still made and I get charged. I am looking for the option not to delete it entirely from the access point list, but rather disable it as I might need connection when WiFi is not available and I want to be able to enable it as once I delete the server name and setting I won't know it.
Is it possible to do it and how?
You could delete WAP accesspoint. Not all providers (carriers) allow this.

How to low level format an external hard drive on Yosemite

I need to perform a low level format on an external hard drive as the WD external hard drive does't provide instructions for doing it on my Mac with Yosemite.

Drive Partition and Format
1. Open Disk Utility in your Utilities folder.
2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Click on the Partition tab in the DU main window.
3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Click on the Options button, set the partition scheme to GUID then click on the OK button. Set the format type to Mac OS Extended (Journaled.) Click on the Apply button and wait until the process has completed.
4. Select the volume you just created (this is the sub-entry under the drive entry) from the left side list. Click on the Erase tab in the DU main window.
5. Set the format type to Mac OS Extended (Journaled.) Click on the Security button, check the button for Zero Data and click on OK to return to the Erase window.
6. Click on the Erase button. The format process can take up to several hours depending upon the drive size.

Premiere Pro CS6 - A low level exception has occurred in ImporterMPEG

Hi Adobe Community,
I'm having a bit of an issue with the ImporterMPEG.prm plugin for Premiere Pro CS6 that's causing playback and exporting issues.
Computer Specs: Win7 PC, NVIDIA GeForce 6150SE nForce 430 graphics card
Description: After playing back video for a while, Premiere will eventually start repeatedly reporting "A low level exception has occurred in ImporterMPEG". The preview player will be completely frozen, and I'll be unable to export. The exporting will fail with a generic "Unexpected error" message.
This issue has only started a week ago. Until now, I've been able to use Premiere Pro CS6 with no issues. If possible, I'd like to avoid upgrading to CC 2014, because the CS6 version was working fine before.
So far, I've tried a few things:
• Deactivating and reactivating (which, by the way, apparently doesn't help subscription users like me, per my recent chat with Adobe support on this issue)
• Uninstall and reinstall (I didn't know about the CC Cleaner tool at the time, so I haven't tried a clean uninstall yet)
• Change the Preview File Format in Sequence Settings (from I-Frame Only MPEG which had worked since I installed the software over a year ago to Microsoft AVI)
• Crying silently to myself (this did not help, the computer is cold and cruel)
• Clearing out the media cache (which I'd never done before and let it get up to ~75GB without me noticing)
• Moving the plugin from its location in Program Files, hoping that maybe Premiere Pro would notice it was missing and to try to find a new fresh one (it didn't work)
So far, only the Preview File Format change seemed to bring relief, but the bad behavior came back after about a week.
I'm thinking maybe the ImporterMPEG.prm plugin got corrupted somehow? The one notable thing I can remember with the computer in the last few weeks was a power event that shut down my computer unexpectedly. I think I had Premiere Pro open at the time.
If it's relevant, I mostly work with .AVI, .MP4, and .TS files in my projects, all varying resolutions and FPS. I'm usually working with about 1GB of files in a project, very rarely more than 2GB.
Has anyone else had this issue? Or, even better, has anyone else resolved this issue?
Thanks!

But really, the real solution for me was to not update Premiere Pro CS6 after a reinstall. The most recent updates just do not like my computer, I guess.
Figured I should post this solution here in case anyone in the future has this problem. (relevant: xkcd: Wisdom of the Ancients)
