Count number of triggered events

I'm trying to continually retrigger a digital output; is there a way to count the number of times the trigger has occurred?
Right now I have it set up where it triggers off the 20MHzTimebase. Would using the counter CI Count Edges on the 20MHzTimebase give a correct reading? Or is there a better/known way to do it?

just one little addition to the vi provided in the previous post from Vij@y,
I would place the Trigger-Button inside the eventcase of the Trigger.valuechange, so it will reset after it is read out without the toggeling.
In addition, the count indicator belongs before the event structure so it correctly shows zero if the program is started but no button has been pressed yet. (another option would be to enable "clear indicators when called" on the vi properties...execution page).
Still, this has nothing to do with the original question.

How to count number of edges using PXIe-6363 Counters

Hello,
I am trying to count number of edges in a test signal in a 50 ms duration. I am using PXIe-6363 card and connecting the test signal to CTR 0 SRC (PFI 8). Is it a correct connection? What else do I need hardware-wise to make a correct set up for this application?
Thanks

Hi Jeet,
When you say interrupt signal, do you mean a pulse that will pause your counter task? If that is the case, and you want to pause your task with a digital pulse, you need to use the DAQmx Trigger Property Node and set that to Pause, Trigger Type. As you said, you can connect that signal coming from the chip to any PFI line and then set that line as the source of the property node.
There is an example that you can use that does exactly what I just described. This example is called Count Digital Events-Pause Trig.vi, and you can find it by going to Help>Find Examples..., then on the NI Example Finder window go to the Browse tab and navigate in the folders to Hardware Input and Outpout\DAQmx\Counter Measurements\Count Digital Events.

How to Count Number of completed line items in past 6 months / 12 months ?

How to Count Number of completed line items in past 6 months / 12 months ?
Hi,
I am trying to count "Number of Completed Line Items in Purchase Order Document" for my Key Figure ZPO_CNT.
Purchase Order document = ZEBELN
Line Item = ZEBELP.
I need to find and count if the Line Item has been received in the past 6 months from today and similarly in the past 12 months.
I have "Delivery Completed" field, ELIKZ.
So, based on this would I be able to calculate it in Query Designer?
If so, Please let me know how

Hello Deva
If youe want to calculate the completed line item for last 6 or 12 month then i think u will be displaying the query data for these montrhs...create a customer exit to give you date range and restric it in filter area....
Now Choose any of the below option
1. I would suggest to implement an additional key figure "counter" in cube and fill values with one for which delivery is completed.
Now use calculated key figure in Query Designer based on logic
IF counter = 1 THEN counter ELSE 0
OR
2. create a formula variable based on ELIKZ and use replacement path variable, it will display you no. of docs for which delivery is completed....
Award points if it solves your problem
Revert back in case of further assistance...

Hi
Instead of using counter in a loop use describe statement.
Describe it_sflight.
the no of rows will get populated in the system variable sy-tfill.

Why does iCal insist on formatting a phone number as a hyperlink? How can I prevent this, and prevent iCal from launching FaceTime in response to entering the phone number in the event box?

I just want to enter a phone number into an event in iCal. I do not want to launch FaceTime. How can I just put a phone number in an iCal event, without OSX 10.10 insisting on launching FaceTime in response to entering the phone number? I use a Macbook Pro.

Ever since I upgraded my iPhone 4S to iOS7, it has basically become a brick. It constantly freezes, and the home button becomes completely inoperable. People have suggested a number of fixes for the home button problem ("calibrating", tightening screws, etc.) but none of the fixes solved the problem. Through trial and error, I've come to realize that the problem is that the phone doesn't have enough computing power and that too much of its RAM gets used up by background processes, causing the phone to freeze.
I have found an app that stops unnecessary background processes currently running, frees up RAM, and lets the phone function properly (Free RAM 1.3). Once I've run this app, the phone functions perfectly.
However, this clean up only happens each time the app is launched (ie: it does not continuously free up RAM). So, I constantly have to run it (and sometimes am not able to because the phone is frozen and the home button won't work).
When it is running, the app displays the background processes that are running. Looking at the list, there are many processes for which I have no need, such as processes related to automatic checking for app updates, processes related to iCloud (which I do not use), etc. Preventing these processes from running in the first place would go a long way in making my phone more useable (being able to return to a previous iOS would be a better option, but Apple won't allow this).
Here is my question: is there a way to prevent unnecessary background processes from running at all?
Which app is this?

How to count number of ones in table

Hello,
i created one table 16x32 each cell is updating 1 byte of data,how to count number of one in all cell,and is it right way to calculate check sum??
thank you

The simplest way is to call GetTableCellRangeValues with VAL_ENTIRE_TABLE as the range, next summing array elements.
But I don't understand your comment on checksum, so this may not be the more correct method for your actual needs: can you explain what do you mean?

URGENT HELP NEEDED: counting number of particles from image

this image on the left is showing particles
hello i want to create a small VI that can count number of particles from a image that i load up. please see the attached image of particles and the VI printshot.
I have used the tutorial "counting number of particles" but still the above VI does not work. it shows the number of particles = 1.. I do not know why it is doing so??
I am not an expert in Labview so please can someone tell me where the problem is. sorry i could not attach the VI file itself but i have given an image of it..
after anyone has solved this problem, i have to create a live system that will get live images from the camera - four frames every sec and the above VI has to count the
number of particles for each frame and output to the user?? is this possible can anyone do it for me???
p.s. in the above VI i read the image from file and count the number of particles. i do not do it to the binary image becuase the binary image is only a black screen
when i run it
thankyou

Hi Farhan,
Vision Assistant would be the best option to create some steps which you can then export to LabVIEW. You should try using the IMAQ Find Circles.vi. The attached image helps you find the number of circles of an image acquired from a camera. I have used the IMAQdx VIs in this example.

What is a best practice for counting number of payments in Payroll Run?

I'm trying to get a feel for what people are using as a means for counting number of payments being created during a payroll run. I would like to get a total number of checks, direct deposits, wires and zero net checks. My initial thought is to use the Pre-DME number "Selected and Evaluated Persons". This number seems to always match the number of persons "Selected" and "Evaluated" in posting to FI/CO.
Since many companies are restricting use of SE16 and access to many of the BT tables is locked down, I would like to use something that the end user has access to and can easily use. I don't believe the spools from RFFOUS_C and T are appropriate since it would have overflow pages (2 page REM Statements) in that number and thus would not be an accurate reflection of total number of payments.
I would appreciate your insight and thoughts on this topic.
Thanks!

Hello Jennie,
This is what we do every payroll:
1. After running live payroll and before exiting our users run wage type reporter /559 to get the payroll net pay. They also run Postings to FICO simulation run to check payroll net pay GL account. This match all the time. So this is the first pass.
2. They finish all subsequent activities in PRD run upto RFFOUS_T.
3. We have developed a custom report which almost looks like REGUH which gives the net pay details by every payment method and amount to be deposited or paid. We match this report from the output we received from step 1.
4. Run postings to FICO live and check the payroll net pay GL account for final validation.
The steps might sound tedious but of a great use.

Regarding Workflow triggering event.

Hi,
Description: I have created a Object type and a event for the same by transaction SWO1, after that i have created a WorkFlow(WF) for which the triggering event is the event i have created in the Object Type. There is a report in which i have used the FM "SWE_EVENT_CREATE" and passed the Object Type, Event Name, Key field values and the creator.
Problem: When i am executing this report the FM is called and the sy-subrc after call is 0, stating that the call was succesfull, but the WF is not getting triggered when i went to transaction SWI2_FREQ to check this WF is not at all triggered. But when i tested from WF transaction SWDD it is working fine.
Could anyone please explain me on this. or is there any other way to use an event of a Object Type to trigger WF.
Thanks and Regards,
Raghavendra Goutham P.

Work Flow - Triggering Event through Webdynpro

Hi,
I am new to Workflow. I have generated the Workflow related to claim (Objects as ABAP Class). Now I have generated Webdynpro component and through this I need to execute the Workflow. I have used the FM SAP_WAPI_START_WORKFLOW & SAP_WAPI_CREATE_EVENT. To raise the event 'cl_swf_evt_event=>raise'. I have used. But this is not triggering event. So, Any one can help me on this issue.
In workflow using ABAP CLASS is essential or Business object.
In my case I have used only ABAP CLASS. In workflow I have generated the Triggering event as SAVE. In webdynpro I have generated the code in 'ONACTIONSAVE'. When ever the user clicks SAVE' button. Workflow shouild trigger and approver should receive the mail as notification and he/she will approve/reject the claim.
Thanks & Regards
Kannappan

After SAP_WAPI_START_WORKFLOW do you have COMMIT WORK?
Does the SAP_WAPI_START_WORKFLOW return some error message?
Are you sure that the event is not triggered? Check this with event monitor SWEL (turn monitor on in SWELS).
Also, ready Jocelyn Dart's blogs about ABAP OO. She have clear instructions about how to trigger ABAP OO events.

Karri

Triggering event from for-each

Hi,
I have a process that takes long to execute, I want to be
able to send a progress notification to the user with the hope of
not getting him bored or impatient, for some reason I can't achieve
it and I don't know where to go for help, if you know how to solve
this, any help will be greatly appreciated.
I have some code like this:
<code in mxml for my application>
- component declared .. onXEvent="showProgress()"
- script for showProgress calls refresh for ProgressBar
Component
</code in mxml for my application>
<code for my component>
for each (var myObject:xObject in MyCollectionOfMyObjects)
// do some complex logic and calls methods for this item
// creates and triggers event for progress notification
</code for my component>
I would expect to see my ProgressBar advancing as the process
is completed, but for some reason the process seems to take control
of the execution and no onProgressEvent is fired until the foreach
finishes execution. It will run perfectly in the debugger (step by
step) but it doesn't work at runtime.
Is there any way I can achieve this in Flex?? Is there any
event class I can use to solve this issue?
maybe anyone has done this before or knows a link to more
information on this subject?
Thanks in advance

Flash functions execute within a frame. They finish before
any UI rendering is done. You will have to use callLater , somehow,
within your loop to give the UI a chance to draw.. There is a more
detailed answer to this thread somewhere else.
