Define the number of single retriggerable pulses

Hi everybody!
I generate single retriggerable pulses using a PCI-6602 and BNC-2121 Box (sent to my spectrometer) for my data aquisition.
For every trigger signal one spectra is aquired by our spec. It is very important to have a defined number of spectra, therefore I have to define the number of pulses in a retriggerable single pulse task.
Unfortunatly it isn't possible to use a pulse train instead because the jitter of my source is to high so that each pulse has to be retriggered.
Is there a way to do this?
Thank you very much for your help!

Hi Konradeo,
it is a little bit difficult to understand, what du you want to accomplish. It would much more easier for me and the other forum user, if you could provide use your LabVIEW-Code and a sketch, what du you want to output with your PCI-6602.

How to define the number of tab displayed in Tab page group

Hello,
I have an application with Tab Page group with 8 tabs and the browser is displaying only 5 of thems. I have to scroll to display the remaining 3 although I have enough spaces on the screen to displayed all of them.
Do you know what parameter/setup I need to change to display all of them at once ?
Thanks for your help,

The link is to the closest linkable point in the documentation to the description of the Number of Rows (Item) attribute.
It sounds like you have been trying to enter—unsuccessfully—an item name or substitution string into the Number of Rows attribute. The Number of Rows (Item) attribute is the one that actually allows you to do this. Click on the flashlight icon beside it to get a list of items from the application.

How can i define the number of pdf-pages that will be print on each page?

Hey everyone,
im currently working on a handout for my prensentation.
That handout will be downloadable for everyone.
So, here is the problem:
I have 24 pages in pdf. I want them to fit on 4 printed pages.
In order to have everyone exactly 6 pdf-pages each printed page,
it'd be nice to have a pre-setting for that.
I found some settings for duplex-print but thats not what i need.
Thank You!

How to generate a delayed retriggerable pulse using only one counter with PXI 6070E card

Hi
I have a problem in generating a retriggerable delayed pulse with a single counter(triggered through a signal at gate) using PXI 6070E card. VI was developed in NI LabVIEW traditional DAQ Ver.7.1. I have used the "delayed pulse generator config" VI and a "Start counter" & "Stop counter" VIs for the purpose. But there is no output seen at the out terminal of counter. So I introduced a "wait" VI and set it to 1 sec. Now the pulse output appears but some pulses are missing mometarily after every 1 sec interval. (any solution for this)
I have gone through a few similar requests in the forum but they suggest either to use two counters or to generate a finite pulse train which does'nt fit my application. Moreover PXI 6070E has only 2 counter timers. I am already using one counter to measure the frequency of a pulse train(signal 1). The application requires to generate a delayed retriggerable pulse for every pulse in signal 1. So I have only one counter left.
Can I measure the frequency of signal 1 by analog means.? so that I can use two counters for pulse generation. (Signal 1 is a TTL signal).
Request some help.
Thanks in Advance
Regards

A finite pulse train (N_Pulses >= 2) does require the use of 2 counters on most of our older hardware including your 6070E. If you're just talking about generating a single retriggerable pulse, you would only need one counter.
Here's an example in Traditional DAQ that shows you how to set a retriggerable pulse generation (it also allows you to adjust the characteristics of the pulse on-the-fly).
If you're writing a new program, you might consider switching to DAQmx as it supports NI's latest hardware and recent OSes should you ever need to upgrade. Traditional NI DAQ is no longer in active development. Here's an example of how to implement a retriggerable pulse generation in DAQmx. You should take note that you can't use the two drivers to simultaneously talk to the same piece of hardware, although you should be able to go back and forth by resetting the Traditional DAQ driver before switching to DAQmx.

How to set the number of rows displayed in a classical report at runtime?

Hi,
Our customer has several standard client hardware configuration and would like to enable end users to choose their 'display profile' at login time. This 'display profile' would contain predefined values for these hardware configurations and supposed to set various paramters that should define the number of rows displayed in a classical report region.
I tried to provide parameters on the report region but it refused to accept anything but numerical values. Is it possible to do this?

Get the number of elements in Array

Hi everyone,
Could anyone give me idea on how to get the number of elements in an Array (not number of rows) ?
I tried to find that in both property node and array functions but nothing.
Thanks,
-Kun

You are going to have to provide some proof that the Array Size does not work correctly. Right click on the input to it and select 'Create Indicator'. Run the VI. Go to the front panel and select 'Edit>Make Current Values Default'. Save the VI and attach it to your post.
You can also check the array size yourself. Right click on the index display of the array and select 'Advanced>Show Last Element'. I will bet you that number shown is equal to Array Size -1.
p.s. The number of elements in an array is equal to the number of rows in a 1D array. If you define the number of elements as anything else, you are mistaken.

Define PO Number Range for XYZ plant

HI,
I want to create the Number Range for PO.
Scenerio: -
I m working in ABC Plant and we define the number ranges for PO i.e starts with 4500000000 series.
But now we have 2nd plant XYZ. So we want to create new runmber range for that (should be start 5500000000).
Plz let me know, how can i define new number ranges for XYZ plant.
Regards

Dear Friend,
with respect to plant PO document type restriction not possible, so in this case copy the NB document type define the new document type
SPRO>>MM>>Purchasing>>Purchase order>>Define the no ranges and assign the no range to document type
SPRO>>MM>>Purchasing>>Purchase order>>Define the Document type here you assign that no .range to your document type

Limitting the number of records in query

I like to limit the number of records retrieved in the query. I set Query All Records block property to NO, Query Array Size to the number I want to retrieve. Before doing that, I set form Preference - Array Processing checked. The result is form always retrieves all records meets the search condition. Could someone tell me what's wrong with it?

I do not understand why and what exactly you want to do. The query array size defines the number records your form should fetch at a time, i.e. if you have 100 records in the database and you set the array size to 20, forms will perform 5 fetch cycles to retrieve all records. However, this is transparent to the user and he will see all 100 records. This property is used for performance tuning when working with a large volume of records.

How to confg the number ranges i.e started from an alphabet

number rages started froman alphabet
ex:aa123...... for an production order

Hi,
You need to define the order type for a production orders in tcode opjh
For this order type you need to define the number ranges as external number range.
The defined number ranges should not overlap with the existing ones

Hi,
There are lots of STATE is available for composite instances, like mentioned in the below query. I hope you will get answer from the below query.
SELECT (CASE WHEN STATE=1 THEN 'OPEN AND RUNNING'
WHEN STATE=2 THEN 'OPEN AND SUSPENDED'
WHEN STATE=3 THEN 'OPEN AND FAULTED'

Determining the number of elements defined in an enum

Hello,
I have an enum and I want to determine the number of elements (constants) defined in this enum by source code. I know I can use reflection but I just want to know if there's an easier way.
Thank you very much.

Hey JavaWisdom,
You can use the ordinal method. I made a simple example to demonstrate.
public class NumberOfEnums {
     public static enum Enumeration {
          item1, item2, item3, item4
     public void count() {
          Enumeration[] values = Enumeration.values();
          int numElems = 0;
          for (Enumeration type : values) {
               if (type.ordinal() > numElems) {
                    numElems = type.ordinal();
          // Correct 0 indexed numbering
          numElems += 1;
          System.out.println("numElems : " + numElems);
     public static void main(String args[]) {
          NumberOfEnums noe = new NumberOfEnums();
          noe.count();
}Cheers,

How to use counters of PCI 6251 to count the number of pulses

Hello,
I have inputs from an optical encoder {pulse train} and i need to count the number of pulses for a short period of time to estimate the speed of the DC motor. Could you please tell me how to use the counters in PCI 6251 DAQ. I found something on DAQ STC, whichs says the input pulse should be connected to PF0 {ctr source}, but i have query where do i get the output {number of pulses counted in a particular period of time}.
Looking for your reply.
Thanks & Regards,
bsnr

Hi bsnr,
Thanks for the post!
In MAX (Measurement and Automation Explorer), if you find the device (DAQmx devices) and right-click, you can select pinouts - which should contain a table telling you which pins are what PFI lines.
Then, in labVIEW, you need to generate some code to use the choosen coutner in a task to count digital edges. If your not sure on this, go to Help>>Find Examples>>Hardware I/O>>DAQmx>>Counters.. and take a look at some of the code provide.
ps. It seems (maybe just your wording), but your expecting the counter output pin to provide the number of counted edges - this isn't the case.
Please let me know what you think?
Kind Regards,
Kind Regards

Define the maximum number of registrations

Hi,
my company uses your form central to organise events for the employees. But ofeten the number of seats are limited. There is a way to fix the max number of registrations? Otherwise we have to check every hour the number of registration to see if the number reached the maximum and it is really disappointing.
Sometimes we had more registrations than seats because we couldn't check often enough and so we have to write to apologise because the seats are not enough. You can understand that it is not nice to do.
We hope you will help us.
