Supplying 26 Analog Outputs and 104 Digital Outputs

I am a graduate student in CWRU and trying to control 26 brushless DC motors independently that requires 26 analog and 104 digital outputs. I couldn't find any card that is capable of this task. Can you please suggest some solution to my application?

Hello. I would recommend 7 NI-7344s. Each 7344 has 4 analog outputs to drive servo motors and 32 configurable digital input/output (DIO) lines. However, if you don't need the trajectory control from the 7344 (ie, you're just running your motors with a constant voltage or your feedback loop is slow enough for software), then you could use a few NI 6704 Analog Output boards (each with 16 AO lines) and a few DIO boards (such as the 6503 which has 96 static DIO lines).
If you can give me some more details about your application (what the DIO is used for, what kind of feedback you need, etc), then I should be able to recommend exact products for you.

Merging Smartform Output and Adobe Form Output in a single PDF File

Hi All,
My Requirement is as follows -
I have multiple Smartforms and a single Adobe Form.
I want to merge the Smartform Outputs and Adobe Form output in a single PDF.
I am able to merge multiple Smartform Output in a PDF , but not able to find any way to merge smartform and adobe form output as the Smartform output is in OTF Format and Adobe form output is in PDF Format itself.
I have tried few ways , but could not find any success.
Request you all to give me some direction to this problem.
Thanks & Regards
Bhavika

Kumar,
I am afraid this is not possible using SAP functionality. There are probably 3rd party tools which allow you to merge several PDFs into one, but SAP itself does not offer such a mechanism. There is an internal SAP function, though, which can merge several "parts" (=several PDFs) within an Adobe-created spool request into a single PDF, intended for downloading this PDF from SP01.
This is described in note 1717357.
Best regards,
Alexander

I want to use two analog channels and one digital simultaneously

Hello and thanks in advance for reading this!
What I am trying to do is generate two different signals from the output channels of my interface card (PCI6024E) and simultaneously use a digital line so that I can switch two tranzistors (one NPN, one PNP) which actually control the "flow" of the two signals. This means that both signals need to be "active" while the VI is running and at the same time whenever I want to choose the signal not in use I need to use the digital line so that I switch the tranzistors and I get the desired signal.
I have already created a VI which activates a digital line and while I was trying to add with the NI-DAQmx Assistant the first digital output, I discovered that it c
ould not be used simultaneously, because there was the error code -200324 saying that "Device not available in NI-DAQmx. It is possible that the device is being used by Traditional NI-DAQ or that the device is being reset."
I did reset the device but as I get it when VI runs, it cannot have an active digital channel and an analog output channel at the same time (not to mention two analog channels). Correct me (And make my day if I am wrong but this seems to be the case. Thanks a lot for your time!

Hey Shootist000, Thanks for the replies. First off, I am actually okay if we both have each other applications so I am not concerned about that. It is still unclear from what you have said as to whether I can in fact, use these two separte time machine backup to create two separate profiles on the new hard drive. If that in fact can be done, then - will it create two copies of the apps we both have in the ROOT of the drive as well as placing all the ones we each have separately?
And reading your second reply, makes me think that maybe the partition is the way to go to begin with and then down the road - after I am in the new iMac, I could reformat the iMac 27 with only one partion and restore my son's latest back prior to the reformat thus giving him full access to the 2 TB of the drive.
If this is still making sense, does this mean :
replace the 1TB with a 2TB - but have it partitione - 1.5 TB & 500 GB.
Install(Restore using Time Machine) my latest back up prior to the 1.5 partition
Install (Restore using Time Machine) my son's latest back up prior to the 500 gig partition
Lastly, in order for us both to be using the partioned computer - I am assuming Switch user can no longer be used - so would we need to restart and select our respective partions in order to use the computer? And if so, how would we each be able to be using time machine to back up - two separte external hard drives - with each one dedicated to only one partition? Or ?
Thanks so much.
Ironically, I am only trying to do this so that I don't need to manually install all his apps, setting, games, blah blah for this temporary period. :-)

How to read back the output state for digital output or anlog output ?

I use NI-pci 6221(68PIN) Accquistion card to do measurmet,after i do digital output ,or anlog output ,I find that the output will be maitained by the card.even after i exit my accquistion program.But if i reset the card ,the ouptut also will be reset.
Now if i don't reset the card ,how can i read back the output state,?

Hi Mike,
There is no way for you to internally route an analog output to an analog input. The only solution is to physically connect the two lines together with a wire.
I came to this conclusion through the following steps:
1- Start MAX and select the DAQmx device under "Devices and Interfaces>>NI-DAQmx Devices" that you want to internally route signals through.
2- Click on the "Device Routes" tab on the bottom of the right hand window (It defaults to the "Attributes" tab)
3- Line up the Source with the Destination to see if the connection can be internally routed (either direct or indirect)
I came to the above conclusion by following these steps for a PCI-6251 DAQ device (the analog output & input do not exist in the "Device Routes" tab therefore they do not support internal routing), but you should verify this for your specific hardware. Let me know if you have any other questions/concerns.

Output mismatch between BEx query output and WebI Report output

Hi All,
I have a BEx query in which there are only characteristics placed in rows.
There are combinations of the values of the characteristics giving different records in the query output.
Date is one of the characterisctics in the query output.
There is an output mismatch between the query output and the WebI report output in the following case:
When there are 'Not Assigned' or '#' or blank values, there are additional entries(rows) in the WebI report, giving repeating or wrong entries in the Date field. This is incorrect data.
Is this because of the 'Not Assigned' or '#' or blank values of the Characteristics or is there any other reason?
How do I fix this?
Please helo me with this.
Thanks and Regards,
Srilakshmi B

Hi Rajesh,
I need to verify the WebI report output for records with # and 'Not assigned' values for the cHracteristics in the report.
So I cannot check the WebI report by hiding the # or Not assigned values.
The problem is that in the Query output the records are like these shown below:
Char1                    CHar2                          CHar3                       Date field
A                             B                                 C                                Date1
#(Not assgined)      #(Not assgined)      #(Not assgined)             No value
Where as the WebI report output is as below:
Char1                    CHar2                          CHar3                       Date field
A                             B                                 C                                Date1
#(Not assgined)      #(Not assgined)      #(Not assgined)            Date1
As shown here, there are wrong/repeating entries for the Date field in the WebI report output.
Please check this and let me know what could be the issue and how do I fix it.

Is there a difference between the earphone output and the audio output of the docking connector, or is it in fact the same signal ?

Is there a difference between the earphone output and the audiooutput of the docking connector of the iphone 4, or is it in fact the same signal ?

One basic difference is that the LTE frequencies each is able to operate on are different. After that, it is pretty much the same phone. Others might be able to add to this.

No Center/Sub from Audigy using Klipsch Promedia 5.1 (analog) - NOT a CMSS/digital output qu

I am receiving no center/sub output from my Audigy Platinum card. I have had the card installed on the same system (P4 3.0/ASUS P4800 Mobo/Win XP Pro SP2) for a couple of years with no problems. I recently began experiencing intermittent loss of my center/sub channel. Since I have not changed the connections in quite some time, I was able to rule out an improper output connection. Also, I was able to independently test the speakers themselves and the center and sub are both functioning. Additionally, I switched my Klipsch volume/channel output controller to headphone mode and ran the Creative Speaker diagnostic and I hear four channels (FR/FL/RR/RL) in the headphones (as I do with my front and rear speakers) but I do not receive any signal for the center channel (i.e., no "center channel" speech signal). Based on all of the above, I am certain that the speakers are functioning correctly (I am of course using them in analogue mode), there is no "switch" on the rear of the subwoofer for 2/2., all of my Creative and windows software are configured for 5. audio. I have uninstalled and reinstalled all of the creative drivers and software (using Driver Cleaner Pro in Windows Safe Mode) and reinstalled from my original Audigy CD and then performed a complete Auto Update from the Soundblaster.com site. <Still no center/sub even in diagnostic test!!!!

I want to be clear: I am not confused about CMSS 5. gaming/audio issues; I believe this is purely a soundcard output issue. Despite all the grousing I read about the Creative driver series, I have been most happy with the Audigy Plat card. It has performed extremely well with the Klipsch 5. in gaming, DVD, and audio contexts for several years through numerous driver updates. I know how to configure the settings to get true 5. in any context. However, now I am completely stumped. Is there anything I have overlooked or might try so I do not have to conclude that this great card has just "crapped out" and now needs to be replaced?
Thanks for listening.

Thank you! I had my digital coax connected there with an adapter, but since that can only carry ac-3 and stereo signals im better of using direct 5 chan ( i don?t watch movies on my PC... that?s what the home theater is for) Most games use EAX or some other direct sound, so ill stick with 5. direct analog. who would have thought the digital jack was also for center/sub heh.

Thanks again man!

Feedback using analog input to control digital output

Hi all,
I've got a program that I intended to open and close two valves (and thus actuate two pneumatic cylinders) based on the readings from load cells mounted to each cylinder. The idea was that it would send a digital out to open the valve and extend a cylinder, then close the valve when the load reaches a pre-determined value (with frequency dictated by increasing or decreasing the inlet air pressure and thus the fill time of the cylinder). It would then do so for the other cylinder in a loop. The issue I have is that the response time of the loop actuating the valves was too slow-for a desired force of 1800 N I had to set the limit to 1100 Newtons. It was nice and consistent in this regard but then I started having instances where the valve would stay open long enough to apply a force of 3600+ N. The biggest need in this program is to maintain a consistent load and ensure that the max. load is not being exceeded. I've used local variables and a queue to pass the load values to the valve actuation loop but it did not seem to make a difference. I don't know if part of my problem is the mishmash of data types I'm using in passing the load cell values or if a notifier would be a better bet.
Attached is my code (LV 8.2). Thanks in advance if anyone can offer some guidance.

2 analog input and 1 digital

hi,
i attach the vi..
in the following vi i have a problem with the analogs..
when i'm running the vi.. At the results.. olly one of the analog will show me the measuerements..
at the one time maybe the clock analog will give me the results..
and the other analog nothing.. and opposites..
why they don't work together? and and the 2 analog give measurements at the same time..

Hello Andrikoscy,
For most multi-function DAQ boards what you're trying to do is not possible. If you want each analog input to run on a different sample clock then you'll need to look into a NI R Series Intelligent Data Acquisition Device. These DAQ boards have a built in FPGA and allow for more customization than M Series boards, including independent sample clocks.
To address your questions:
1. On a non-intelligent DAQ board all analog input channels must share the same sample clock--if you need two different rates I would suggest sampling both channels at the faster of the two frequencies and then just ignore some of the data points on the slower channel.
2. In order to find out the exact time between samples from an external trigger (instead of the constant dt inserted by the waveform acquisition), you will need to take a period or frequency measurement of your signal using a counter on your card. By taking a buffered period measurement you will get an array of the times between samples and with that you can graph your samples on a precise x-axis. Normal analog input tasks that use an external clock do not associate any exact timing information with when a trigger was received.
I hope this helps, and if you'd like more information on the R Series Intelligent Data Acquisition Devices please feel free to contact National Instruments directly at www.ni.com/contact.
Have a great day!

How to disable SP-DIF (digital) output on Audigy

Hi, I am using Audigy 2 soundcard connected to Altec Lansing ADA885 speakers. These speakers have built-in Dolby Digital Decoder, and of course SPDIF input for this. Additionally, they have inputs for analog front and rear speakers signal. They can be switched to different operation modes : Dolby Digital decoding, Dolby ProLogic decoding, stereo, and quad modes. I have connected them to my Audigy 2 using analog connections, and also digital output. The problem is, that they process both kind of inputs (analog and digital) all the time in most modes simultaneously. For example, when I set them to "quad" mode (for gaming) they process analog signal that Audigy deli'vers them, but also they attempt to decode the signal from digital input. This produces some kind of phase distortions (basses dissappear and the sound becomes slightly muffled). Possible solutions could be : - disable digital decoding in speakers when using analog output from Audigy - this can't be done, these speakers' decoder is not configurable, - disconnect digital cable when using analog output from Audigy - obvious solution, however not very comfortable - disable "ON-DEMAND" spdif output on Audigy card and enable it when necessary. This would be most satisfying option for me. But.... is it possible at all ? Just something similar to the "Digital output only" setting in soundcard panel, but in my case i'd like to have an option of "Analog outputs only". Thanks in advance for any help Greetings, Martin

PID Control - analog input, digital outputs

Hello everyone,
I am trying to use the PID toolkit to convert my existing feedback control system to one using PID or just PI whatever works best. Problem is that the tutorials out there discuss in detail about obtaining Analog inputs and using the PID output to control an analog output. Are there any tutorials that show how I can control my process variable which is an analog input by using the PID output to generate digital outputs?
Basically, what I am doing is controlling the incline of my device with two digital outputs that control two solenoid valves. The angle is calculated from a calibration curve that plots distance sensor voltage with Angle. Any help would be immensely apprecitated. I want to try this out on my own before I post some vi's. Thanks!
V
I may not be perfect, but I'm all I got!

That is exactly what I am doing currently. I have error bands specified around the target to make sure that it doesn't oscillate. But, under load conditions such as pulsed load conditions, the device goes out of bounds and the values trigger to correct for it. But, what I need is seemless or atleast seemless correction. Currently what I see is sudden adjustments to the incline. Please find attached what I am currently using. I am trying to get a more finer solution if at all possible.
Note: Within 5% of the target = NO action
Between 5% and 15% = Pulsed ACtion ( DO On for Pulse width time)
Greater than 15% = continuous action until it reaches Pulse band
I may not be perfect, but I'm all I got!
