Planning Folders with multiple input and output layouts

Hi,
I have a planning folder with one input layout and 4 output layouts. The input layout has a GPS assigned to it which will be executed before layout change. Will this function get executed when I open any of the output layouts(out of 4) not necessarily the immediate output layout (next to the input layout) and will the calculated data be displayed accordingly. Can some one please confirm me on how that works.
Scenario2: I have one input layout and 2 output layouts. The input layout has a GPS assigned which will be executed before layout change and the first output layout has another GPS assigned which is basically a push button. Then how does this work.
Points will be assigned . Help is greatly appreciated.
Thanks,
Vamsi

GPS will not be executed when you open any of the output layouts but will be executed only when you open the input layout. Yes, the calculated data gets stored in planning buffer so it will the displayed in input/output layouts accordingly.
Scenario2: The GPS assigned to input layout will be executed when you open the input layout. GPS which is assigned to output layout in the form of a button will be only executed when user will click on that button. Calculated results will be available in all the layouts as the result remains in planning buffer until user explicitly click the 'SAVE' icon in applpication toolbar.

How do I create an xControl with multiple inputs and outputs?

Hello,
i am trying to write a new Xcontrol Element. In the data model I can create data types using the cluster to create compound types, eg an int and an int array. But how do I create an xcontrol which has multiple data inputs and outputs?
Kind Regards

Alright: I see: An xcontrol is either an input OR an output. How do I achieve an output? Secondly: So you are saying the only Elements that can have multiple inputs and outputs are VIs?
Can you take a few steps back and explain what you are actually trying to do. SubVIs and Xcontrols have nothing in common and it is not clear why you even try to compare them side by side (e.g. in terms of the number of connectors).
Your questions about input or output tell us that you seems to have some misconceptions about xcontrols. Xcontrols are like regular controls, except they have some built-in intelligence that you can program. Most front panel object can be either controls or indicators and the same is true for Xcontrol. You create an Xcontrol, and after placing it on the front panel you can decide if it should be a control (where the code reads the value) or an indicator (were the code writes values to it). When you define the xcontrol facade, you also need to program how the visuals change if it is changed from control to indicator or vice versa.
As a first step, you should opend the example finder and look at some xcontrol examples.
Again, what are you actually trying to do?

Multiple inputs and outputs using DAQmx VIs

Hello,
I am fairly new with the LabView programming language. I have a few training books that I have been reading, and I have been following online tutorials and reading the forums. However, I have come to a problem where I don’t see a clear solution. I am using LabView 2009 (9.0f3) and DAQmx VIs.
I am using a NI 9172 chassis PLC, with two 9201 AI cards, 9217 AI RTD card, 9472 DO card, 9263 AO card, and two 9237 AI Bridge cards.
I am reading eight analog inputs with the 9201 cards, two analog RTD inputs with the 9217 card, three digital outputs with the 9472 card, three analog outputs with the 9263, and eight analog inputs with the 9237 cards.
I wrote a simple program to test one digital output task, two of the analog output tasks, and a single analog input task. I put all of them in the same while loop, and it worked perfectly. However, when I add analog input tasks to the same loop, I get an error 200022. So I tested each sensor individually by changing the channel before each run. I searched error 200022 and found that this is because I cannot start another analog input task until the previous one ends. With this said, I don’t know how to acquire an analog voltage in the same task as an analog RTD voltage. Both inputs take different constants in the start task DAQmx icon.
Attached is my test program. It is titled “Test All”. This is the program I used to test the various sensors. I tested the input sensors one at a time, and it worked fine. A few tasks are written just to test functionality, and will be added to later. The data is only displayed on the screen. I will add triggers and data write to disk functions later. This program works now, but if I add more analog inputs, it will generate the 200022 error.
Can someone show me how to correctly write the code for multiple inputs and outputs using DAQmx? All training materials and tutorials I can find all show a single input or single output, not multiples of each. Thanks for looking.

Hi RandyC,
The Knowledge Base article Using Different Types of DAQmx Global Channels in the Same Task goes into a little more depth of what Bryan is talking about, and it also includes some example code to help show what to do.
Hope that helps,

Problem with File Input and Output

So basically is my computer not letting this APPLET create a txt file? For security reasons, applets by default cannot access the local file system (on the client) and cannot open any network connections except back to the server that served them up. You can sign your applet, and set up permissions in the JRE that your browser runs to allow the signed applet to do things that applets normally can't. However, before starting down that path, I suggest you examine whether your applet really needs to access the local file system, and if it does, if it should really be an applet, or would be more appropriate as an application.

Multiple Input and Output from a 6534

Hello
I am after some advice regarding my PCI 6543 digital I/O card and the best way to achieve my desired results. I am programming in Visual C++ with Ni-DAQ 7.
I want to generate a pattern output from one of the ports, Port A, following a software command. This pattern consists of a 10uS pulse on DIOA0, that repeats 200 times with a period of 100uS. I want this DIOA0 output line to initiate an input on ports C and D, possibly through the REQ pin. Consequently the input should acquire 200 times for each call to the pattern output.
I want this to repeat, so the pattern output goes again (as in a FOR loop), and the input occurs again for an as yet undetermined number of times.
I have managed to get something worki
ng for 1 iteration, and I can generate multiple pattern outputs, but the inputs only seem to acquire for the 1st iteration. However, if I step through the code in debug mode I can get the input to work correctly.
Any ideas would be gratefully appreciated.
I am still trying to get some earlier problems with this application solved.
Kind Regards
Jamie

Hi Jamie,
There are a couple different ways you can loop from a buffer. You can either use the onboard memory of the 6534 and loop from there or you can specify as a software configuration that the board loop through the PC memory buffer.
For the onboard looping you need to specify the following:
iStatus = Set_DAQ_Device_Info (1, ND_PATTERN_GENERATION_LOOP_ENABLE, ND_ON);
For software, PC memory looping, the following function specifies this:
iStatus = DIG_DB_Config (iDevice, iGroup, 1, 0, 1);
I attached a couple programs that might be of use. Check this post:

CFP-DIO-550 open multiple input and output at the same time

I am trying to read and write at different times with the cFP-DIO-550. I cant figure out how to read all the inputs at the same time.
In the Create Tag.vi, I cant figure what to wire to the Item Name input. I have tried Input 0, and that works, but it is only one input, I need to read all 8. I have also tried Input All, All, Input 0:8. input 0-8, input 0: Input 8, Input 0 - Input 8, and I always get an error.
I cant find anything on it in the manual.
Thanks,
Kenny

Normally I would select 'All' using a FP IO point function instead of create tag ( LV 7.0 and up ). I have noticed that the 'All' is only available if the module is all inputs or all outputs. It may be that since your module is an IO, 'All' is not available by default.
I think you need to create an item in MAX in the Data Neighborhood under the DIO-550 Module and configure it to use all the IO on the module.

SSIS: How to use one Variable as Input and Output Parameter in an Execute SQL Task

Hello,
i need your help,I'm working on this issue since yesterday and have no idea how to deal with it.
As I already said in the tilte i want to start a stored procedure via a Execute SQL Task which has around 15 prameters. 10 of these should be used as input AND output value.
As an example:
i have three Variable:
var1    int        2
var2    int     100
var3    int     200
the stroed procedure:
   sp_test
     @var1 int
      @var2 int output
      @var3 int output
   AS
   BEGIN
        SET @var2 = @var2 * @var1
        SET @var3 = @var3 + @var1
   END
So in the Execute SQL Task i call the Stored Procedure as follwos:
    Exec sp_test  @var1 = ?, @var2 = ? output, @var3 = ? output
(I use an OLE DB Connection)
The parameter mapping is as follows:
User::Var1        input                   numeric              0                 -1
User::Var2        input/output         numeric              1                 -1
User::Var3        input/output         numeric              2                 -1
Now my problem. If i set  Var2 and Var3 as Input parameter the values are still the same after running the package. If i set them to a output value the are both Null because the procedure doesnt get any values.
I already tried to list them a second time - like
    User::Var2        input                  numeric              1                 -1
    User::Var2        output                 numeric              1                 -1
or i use a new variable
    User::Var2                  input                  numeric              1                 -1
    User::Var2Return        output                 numeric              1                 -1
but i alwas get the error
"Multiple-step OLE DB operation generated errors. Check each OLE DB status value, if available. No work was done."
Has anybody an idea how I can solve this problem?
Thanks a lot.
Kind Regards,
Alice

Hi Alain,
thx for your answer.
I have around 15 procedures called one after the other to calculated and modify my values. Each procedure is responsible for an other but overlapping set of variables. So i thought it would be a good idea to call them one after the other with the needed variables via a execute sql task.
So if i use a result set, how i get my stored procedure to return 10 values? I would have to use a Function instead of a procedure, wouldn't i?
As if i have 15 procedures this would be a lot of work.
But thanks a lot for the idea. I think an other idea would be to create one function which calls all stored procedures and returns all the calculated values as a result set, wouldn't it?.
Kind Regards.
Alice

FINALLY INPUTTING and OUTPUTTING Annotations!

Ok, before everyone thinks that this is a very bad solution, I have to tell that I`m no programmer and my knowledge of PostgreSQL, Ruby or any other language is very poor.
With useful help from Jamie Hodge, fbm and Nicholas Stokes (mainly)
I could manage to write a command for inputting and outputting from Final Cut Server Annotations.
So lets go to the fun part:
INPUTTING:
1- Create a Response called "Annotations IN" (or whatever you want):
a - Reponse Action: "Run an external script or command"
b - Run Script > *Commnad Path: /Library/Application Support/Final Cut Server/Final Cut Server.bundle/Contents/Resources/sbin/fcsvr_run
Command Parameters: psql px pxdb -c "COPY pxtcmdvalue FROM '/FCSRV/annotation-in.txt' USING DELIMITERS '|';"
2 - Create a poll Watcher with name: "Watch for Annotations IN"
a - Enable: true
b - Monitor Address: Chooses a Device (create a new one or use a tmp one) and path to where you`ll going to put a txt file with the annotations.
c - Response List: Choose the Response you created "Annotations IN" in my case.
d - Event Type Filter: Created, Modified
e - Poll Watcher > Listing Frequency: 2 (or any number of seconds you feel like it).
Listing multiple: 2
Wildcard include Filter: *.txt (or any custom extensions you want)
3 - Create a txt file and use this as a template:
{ASSET_ENTITYID}|1527|{TCIN}/(30000,1001)|{TCOUT}/(30000,1001)|{Annotation}|{USE RID}|{DATE}
Where:
{ASSET_ENTITYID} = Is the entityid of your asset. You can find what number it is by issuing:
/Library/Application\ Support/Final\ Cut\ Server/Final\ Cut\ Server.bundle/Contents/Resources/sbin/fcsvr_run psql px pxdb -c "SELECT pxmdvalue.entityid, pxmdvalue.value AS asset_name FROM pxmdvalue INNER JOIN pxentity ON pxentity.entityid = pxmdvalue.entityid WHERE pxmdvalue.fieldid='1543' AND pxentity.address LIKE '/asset/%';"
This will output ALL your assets, so if you know the name or want to parse the name you can use:
/Library/Application\ Support/Final\ Cut\ Server/Final\ Cut\ Server.bundle/Contents/Resources/sbin/fcsvr_run psql px pxdb -c "SELECT pxmdvalue.entityid, pxmdvalue.value AS asset_name FROM pxmdvalue INNER JOIN pxentity ON pxentity.entityid = pxmdvalue.entityid WHERE pxmdvalue.fieldid='1543' AND pxmdvalue.value='ASSETNAME' AND pxentity.address LIKE '/asset/%';"
Where in ASSETNAME you`ll have to put your Asset Name without extension.
{TCIN} and {TCOUT} is, of course, the TC`s points. In the form of: HH:MM:SS;FF
{Annotation} is the commentary.
{USERID} (in my case was 1)
{DATE}: This one is tricky. My example is 2009-03-15 19:31:15.839795-03
So is in the form YYYY-MM-DD HH:MM:SS.????? I really don`t know the rest. Could be milliseconds?
Of course one can write a script to translate everything from a txt file like:
ASSETNAME | TCIN | TCOUT | ANNOTATIONS | USER
But as I`ve said I`m no programmer
Ok.. now the time for the OUTPUT:
The command-line is:
/Library/Application\ Support/Final\ Cut\ Server/Final\ Cut\ Server.bundle/Contents/Resources/sbin/fcsvr_run psql px pxdb -c "SELECT pxmdvalue.value AS Asset_NAME, pxtcmdvalue.value, pxtcmdvalue.begintc, pxtcmdvalue.endtc FROM pxmdvalue INNER JOIN pxtcmdvalue ON pxmdvalue.entityid = pxtcmdvalue.entityid WHERE pxmdvalue.value='ASSETNAME';"
Where ASSETNAME is the Asset name without the extension.
Or issuing the following to OUTPUT ANNOTATIONS from ALL assets:
/Library/Application\ Support/Final\ Cut\ Server/Final\ Cut\ Server.bundle/Contents/Resources/sbin/fcsvr_run psql px pxdb -c "select * from pxtcmdvalue;"
Adding "> /PATHTO_WHERE_IN_WANT/ANNOTATIONSOUTPUT.TXT" at the end will put all output into a txt file.
It`s possible (in theory) to:
1- Create a boolean md field in FCSRV called "EXPORT Annotations" (don`t choose lookup)
2- add or create a md group called "Export Annotations" and add the above md field to it (don`t choose lookup)
3- Add "Export Annotations" md field to Asset Filter md group
4- Make a Response for Running external command. Command path: /Library/Application Support/Final Cut Server/Final Cut Server.bundle/Contents/Resources/sbin/fcsvr_run
Command Parameters: psql px pxdb -c 'SELECT pxmdvalue.value AS Asset_NAME, pxtcmdvalue.value, pxtcmdvalue.begintc, pxtcmdvalue.endtc FROM pxmdvalue INNER JOIN pxtcmdvalue ON pxmdvalue.entityid = pxtcmdvalue.entityid WHERE pxmdvalue.value=[FileName];' > ~/Desktop/ann-out.txt
(I`m having problem with this, it doesn`t work).
5- Make a Subscription that if Export Annotations modified = true, trigger if changed and trigger the Response above.
6- Add exporting annotations md group to Media md set.
In theory it`s possible to modify the FinalCutServerIntegrationSample get and input annotations instead of adding another "comment" field to md group list.
Few!
Ok so please help beautify this out!
This will be very useful for a lot of people.... We know that it`s only a matter of time to FCSVR have this function built-in... but this "time" could be years.
So let`s start ourselves!
Thank you very much!!
Regards!

XiFi and Audigy Take Over Input and Output from Bluetooth Head

I am having trouble with my bluetooth headset when making phone calls in any VoIP application (Skype, Yahoo!). I usually use the headset as the input and output for my VoIP bits so I can move away from my desk, etc... First, it worked under XP with my Audigy no problem. I bought a XiFi and installed the latest drivers and it began stealing my audio. Oddly, it does not do it until the call connection is made (so I hear the ringing in the BT headset and once the call is answered the system reverts to the mic, a Logitech USB, and main speakers, directly plugged to the soundcard).
I decided to put my audigy back in, because I was planning on upgrading to Vista and thought the XiFi may be bad. I did a fresh Vista install with the Audigy and everything worked (i.e. audio for phone calls stayed in my BT headset). I then upgraded from the Microsoft drivers to Creative?s Vista drivers and the problem then happened with the Audigy as well.
This leads me to believe that some sort of regression happened in the latest drivers. Everything else works great, games, movies, etc? but this is a show stopper because I want to use my bluetooth headset. I tried to downgrade to the Microsoft drivers but the card would no longer work. I have tried a driver install only, then added the software, removed that and did a full install. This is with BETA drivers on Vista, but the problem existed in XP as well which were not BETA drivers AFAIK. I have updated to the latest Bluetooth drivers as well with no luck.
I have confirmed this on two of my PCs and a friend of mine is having the same problem (XP, XiFi) so he went and bought a Skype phone which works correctly.
Thanks in advance

How to set the input and output of a subVI

I am trying to configure a subVI by following Chap. 7 of "LabVIEW fundamentals". But I stuck at "Building the connector pane".
My subvi is quite simple, just for testing purpose. I plan to do a summation and display the result. So I placed one numeric Add icon on the block diagram and a numeric Indicator on the front panel. I built a connector pane with three terminals, two for input and one for output.
But, how could I associate the terminals on connector pane with inputs and outputs of terminals on the block diagram? I wanna build a subVI, whose input are two numbers and display the summation on the subVI.

Hi Forrest Bao,
use the right mouse key as often as you can in LabVIEW. It´s very helpful. If you right click on a link in the connector pane, then you can select to disconnect selected or all.

Statistical forecasting....Input and Output at different levels? & MAD and MAPE calculations

Team,
Couple of questions on Statistical Forecasting...
1) Is it possible to have input and output KF at different planning levels?...
2) Is there anyway to see MAD and MAPE values for each Forecast run?
Any help is appreciated....Thanks for your help...
Thanks,
Krishna

Hi Krishna,
#1 - The Inputs and Outputs should be at the same base planning level. Output should be a Stored KF. The input can be a calculated KF.
To achieve input and output at different plan levels, you can do something like this:
I/P KF1@PL1 (stored) Output: KF3@PL2
Create a Calculated KF: KF2@PL2 with calculation like SUM(KF1@PL1) and use this as input for StatFcst
#2 - The result of Fcst run MAD cannot be seen from Excel Client yet, we will address this in near release. If you are on-premise, you can see the results in table: sap.sop.sopfnd.catalogue::SOPFCS_FORECAST_RUNTIME_INFO_TAB
Hope this is useful.
Thanks,

Synchronisation of input and output using myDAQ

Hello!
I am currently using the NI myDAQ and use both analoge output. and both analoge inputs. The sampling rate needs to be as high as 200k Hz. (Also within the while loop I do quite a lot of data manipulation and saving into text files.) My vi works generally fine, but I still have to problems:
1. How can I ensure that the read and write tasks are synchronised? I found out that it is not possible to use other trigger than the sample clock for write and read tasks using the myDAQ. (Is this right?) So as a workaround for me it is not important that the tasks start at the same time, but I want to ensure that the delay between "Start Write Task" and "Start Read Task" always is the same. Is this possible? And how can I realise it?
2. If I want to generate a non periodical signal that is not constant, how do I best generate this? At the moment I use a Sine Waveform.vi with a frequency of 0 and I change the offset input with every loop. I also tried to use the FormulaWaveform.vi but with this my produced waveform seemed to stop after completing the "number of samples in the waveform". But the sampling info must be the same for both AO channels I use, so I cannot simply increase this number.
Thanks a lot for any help! Jules

MyDAQReadWrite.vi ‏72 KB

hi Jules,
If you only want to ensure that the delay between "Start Write Task" and "Start Read Task" always is the same, you can realize it with a simple while loop (with Wait Until Next ms Multiple).
But if you want to synchronize for example both analog input, you can see how it works in different examples. Following Path is shows you how to find these examples:
In LabVIEW -> Help -> Find Examples... Brows(Brows according to Task): Hardware Input and Output -> DAQmx -> Synchronization -> "Analog Input Synchronizantion.vi"
To generate a non periodical signal that is not constant, you can change the offset input every loop. If you want to manipulate the offset while running you can also use local variables in the loop.
In this case you could manipulate for example with a slide control.

How can I use a different driver for audio input and output?

I did a search of course, and came up with something about an aggregate. I have no idea what this is, how to do it, or if it would even work for me.
What I am trying to do is:
1) Record into Logic Express using my Tascam US-122.
2) Have playback come out of my computer sound system, not the Tascam.
If I go over to the Audio setup window, I can only record when the driver is set to Tascam US-122. Likewise, I can only listen to sound when my Built-In Audio is selected. It gets rather annoying going between the two.
So, would this aggregate thing solve my problem? If so, how do I do it? Thanks for any help!

Yes it should do what you want.
Go to "Audio Midi Setup", and go to the Audio menu and click "Open Aggregate Device Editor". The interface is pretty simple but if you do get stuck, just use the help function in Audio Midi Setup, as it has a step by step guide.
Then when you return to logic, go to the Preferences>Audio>Drivers section and select Aggregate Device as the new driver rather than either the built in sound or the tascam. Then the inputs and outputs will apply to BOTH devices.

How can I make Apple Earphones be the Input and Output for Audio

I have some older headphones and they aren't compatible with a Mid 2010 (Intel Core i3) 21.5 Inch iMac
Is there some way to make Apple Earphones be the Input and Output for Audio in the iMac
This is a problem for me personally as when I am talking to someone on Skype the iMac picks up the In-built Microphone audio, and yes the headphones I'm using do work straight from the iMac as audio output
Any help is appreciated

you can connect the headset to something like this

and then connect the mic to the input and the headset to the headset port
