Using EXT trigger 3499A and polling status

I was looking for a way to use the EXT trigger as a way to make my code wait. I am not familar with its function though. Looking through the manual, I do not see a way to status the trigger. I was hoping I could set the EXT trigger up and then poll its status. Once I see it has triggered, I can continue on with my code. I am sending RS-232 commands if that matters.

That does not sound like a LabVIEW question. It is very instrument specific. You have not specified it but I'm guessing you are referring to the HP/Agilent/Keysight 3499. If there is something, it would probabl;y be in one of the instrument registers (Status Byte, Event, etc.) or OPC. A quesry to the vendor is going to provide the best information.

Frequency measurement with High Speed Digitizer using External Trigger

Hello:
I have a

Hello Brooks:
Thank you for attention !
I will try to explain my application:
I need to measure a signal of a speed/position sensor. This sensor works with hall effect principle and is placed in front of a wheel with some teethes. Is used for automotive purpose in CAM and CRANKSHAFT applications. So, I need to measure period, duty cycle, rise time, fall time, Vpp, Angles for each teeth x encoder, everything from 40 to 7500 rpm.
I'm using CH0 to measure a signal of this speed/position sensor.
I'm using CH1 to measure a signal of an encoder connected to wheel.
I'm using EXT Trigger to sync acquisition with encoder's INDEX signal.
I need to measure the frequency of EXT trigger to know the instantly speed of the wheel.
So, If I know that my encoder has 2048 pulse/rev, I can measure FFT_FREQUENCY of CH1 with scalar measurement functions and calculate the speed !
The NI-Scope is wonderful because it can measure a lot of things automatic and fast, like period, frequency, duty cycle, rise/fall times ...
Now I have one more question:
I want to use 10:1 attenuation but I can't use a common probe. I want to connect the CH0 to sensor with a special connector.
I've tried to make the same circuit with 9MOhms and capacitor like explained on site, but I reached bad results. The industrial probes has special characteristics for capacitance and noise rejection.
Do you know how can I solve it ?
Thank you.

I inadvertedly changed a setting where the top of my screen no longer shows the apple logo in the top left or the clock and wifi status and strength on the top of the screen, how can I get it to show both of these things again like it used to?

I inadvertedly must have changed a setting where the apple logo and files and things that used to be in the top left corner of the screen are no longer there as the clock and wifi status and other installed settings used to show up in the top right hand corner of my screen. When I move my mouse to the very top of the screen they drop down but when I move my arrow away from the very top of the screen they both disappear again. So I was wondering how can I get it to revert back to the way it used to be? I hope this isnt confusing.

I tried the zoom thing but it still didnt resolve my issue Im gonna try to clarify my issue a little bit more, before the change, my screen when I would surf the web would have the apple logo and safari and file and edit and view buttons at the top left hand of the screen and the upper right hand screen would have the time and the wifi strength and my name and the spotlight box and a volume control but now they dont show while Im browsing the web unless I take my arrow and move it to the very top of the screen then those boxes will drop down like it used to be but when I take my arrow and move it from the top of the screen it disappears again and ll I get is a back and forward arrow and the url input bar. Anyone else have any ideas of what I did to mess this up?

How to use the selection profile and status profile for production order?

Hi expert,
I want to know how to use the selection profile and status profile for production order. what's the usage for these two selection profile and status profile ?
Please help me.
thanks in advance.
george.shi

Hi George,
There are are two types of statuses.One is system status and second one is user status.These statuses will tell us current situation of an order.
We can't change system statuses.But we can create our own statuses through status profile.With this profile we can control user statuses.
In this status profile,
1.We define the sequence in which user statuses can be activated,
2.We define initial statuses
3. Allow or prohibit certain business transactions.
Selection profiles are used to select the objects (say production orders) with different status combinations.We assign status profiles to selection profiles in BS42 T-Code.
Regards,
Raja.

Fetching the sales order data using both system status and user status

Hi,
Could any one tell me how to fetch sales orders using both system status and user status.
My requirement is to fetch sales order data in a report where the user enters the system status and user status in the selection screen fields.
For example i need sales orders where the system status is I1002 i.e. OPEN and user status is E0002 (status profile CMSCON0) that is In Process
Early replies are appreciated.
Thanks
Tanveer

Hi,
The system status and user status are stored in CRM_JCDS & CRM_JEST tables you can get the all the order GUID on particular status further pass the order GUID in table CRMD_ORDERADM_H to get transaction ID.

HT204492 If you're using the paired remote and the Apple TV status light flashes white, the problem isn't with the remote.

If you’re using the paired remote and the Apple TV status light flashes white, the problem isn’t with the remote.
Then what is the problem since I have troubleshoot my remote, it is working but cannot do anything on apple TV?

If your problem persists get yourself a micro USB cable (sold separately), you can restore your Apple TV from iTunes:
Remove ALL cables from Apple TV. (if you don't you will not see Apple TV in the iTunes Source list)
Connect the micro USB cable to the Apple TV and to your computer.
Reconnect the power cable (only for Apple TV 3)
Open iTunes.
Select your Apple TV in the Devices list, and then click Restore.
(You may already have a micro USB cable if you have a camera or other digital device)

Shipping and delivery status from R/3 to CRM

Hi all,
we are creating sales orders in CRM and replicating it to R/3. CRM is the owner of the document.
Now whenever changes are done to sales order in CRM, the changes are replicated to R/3.
Let's say the shipping status is updated in R/3. Now the requirement is the changes need to be replicated
back to CRM.
I can use the scenario X + Y or X alone. But with X or X + y scenario Once I make changes in R/3 then the
document owner changes to R/3. this means any further changes in CRM will not be replicated back to R/3.
I require all changes from CRM to be replicated to R/3, but from R/3 I require the shipping and delivery status to be replicated back to CRM. How could this be achieved.
It would be great if you could share the experiences.
Thanks
Jothi.

Hi all,
I have a similar requirement. Can you please tell me how to go with it?
The requirement is to send the user status from CRM (where the request is generated) to R3 (where the material is processed).
The user status of the return order in CRM should be sent real-time to R3. Any updates to the user status in CRM should result in a corresponding change in the user status in R3. Any updates to the user status in R3 should trigger a corresponding change to the user status in CRM. All user statuses must be available in BI/BW for reporting and analytical requirements.
From R3 to CRM Standard R3-CRM middleware exchanges information between the two systems any time a transaction is created or changed. At this point the order information is exchanged between the two systems depending on whether the item or the header level data is changed in R3. The development should be able to download the user status at the header & the line item level when the middleware brings down R3 sales transaction data to CRM. For the sake of simplicity the status profile in R3 and CRM will be defined exactly the same therefore we do not need a mapping table between the two systems. This information should also be exchanged in case the line item is deleted / cancelled / rejected.
The same from CRM to R/3.
Processing restrictions :
This should not be transaction, item category or status profile specific so that as and when a new transaction type, item category or a status profile is added it should still be allowed to transfer between the two systems.
Should be developed as an enhancement to the standard middleware data stream between R3 and CRM.

Raju

*when we use at user -command and give smaple code fro at user-command*

Hi experts,
i am new to abap can any body tell me when we use AT USER-COMMAND and give a sample code for that.
point will be rewarded.
thanks.

Hi,
AT USER-COMMAND is a list Event.This Event is triggered when user make an action on the Application Toolber Or Menubar.
Here is the Program.
START-OF-SELECTION.
SET PF-STATUS 'TEST'.
WRITE: 'Basic list, SY-LSIND =', sy-lsind.
AT LINE-SELECTION.
WRITE: 'LINE-SELECTION, SY-LSIND =', sy-lsind.
AT USER-COMMAND.
CASE sy-ucomm.
WHEN 'TEST'.
WRITE: 'TEST, SY-LSIND =', sy-lsind.
ENDCASE.
This program uses a status TEST, defined in the Menu Painter.
Function key F5 has the function code TEST and the text Test for demo.
Function code TEST is entered in the List menu.
The function codes PICK and TEST are assigned to pushbuttons.
The user can trigger the AT USER-COMMAND event either by pressing F5 , or by choosing List -> Test for demo, or by choosing the pushbutton 'Test for demo'.The user can trigger the AT LINE-SELECTION event by selecting a line.
Hopr This Will help You.

Sujit

Use reference trigger for cyclic recording data

Hi,
Before I start, let me briefly introduce what hardware I have and what I want to achieve.
I got SCXI-1000 (Chassis), SCXI-1102C (module), SCXI-1303 (terminal block,
mainly for temperature sensor input); a couple month ago I bought feedthrough SCXI-1180 and terminal SCXI-1302 to input my digital signal (see attached PNG file). In fact, I have two digital signals to input. The first one is Injection digital signal (input as PFI0) which will trigger the start of recording my
temperature profile; The second is packing signal (input as PFI1), which I want to use as a reference trigger to stop the recording and save as the cycle file.
And then the injection cycle keeps going. Please see the attached VI for details.
I get my digital trigger working to start recording my temperature sensor profile. However, I can't get the second part trigger to stop the recording.
The error message from running my VI is that a reference trigger is only applicable for finite sampling. It seems that I need continuous sampling to recording my temperature profile! So, by looking through my VI, please give some suggestions to do the task and solutions to solve the conflictions for sampling.
Your assistance is higly appreciated.

Hi, Jim:
I've tried with the way you suggested to poll out the digital line. In your VI, it will stop the running of the whole program when the second signal jumps up. If you see my VI attached, I'd like to start recording with the first trigger and then stop the cycle file by the second trigger signal falls down, and then keep recording the second cycle until clicking stop (reference to my signal illustration).
So what I am trying is to use both trigger signal to output a boolean value (when both trigger signals are 0), reverse it to true (1), and use it to stop the cycle file. But I am still little far away from doing the task. Is there any way to do the cyclic file as I want with or without 'Write to Measurement File' VI?
Please edit my VI and save in V8.5. Thanks for your help!
Best Regards

Retrieving latest updated or inserted records without using a trigger

I have to retrieve the latest updated/inserted records from a set of database tables. Say, if 'n' sets of different records have been updated or inserted into one or more different database tables then all the 'n' records of data should be retrieved using a java code without using a trigger.

helpmeplz wrote:
Thanks for your reply.
But I don't know when or from where or what kind of data gets inserted/updated into the tables. I need a listener or a component which can handle events occured on the particular set of database tables, and get the event data. the java code should get the updated/inserted rows that have been inserted into a set of database tables by a third party.
Please lemme know how I can do this.Realistically you can't.
If and only if the tables have a modification timestamp then you could use that. Every table would need it.
Other than that the only othe possibility would require that you keep an entire copy of each table in the memory, poll at a set interval and then do an entire comparison for each table. For very small data volumes (on the target tables) that is practical. For larger volumes it isn't.

Uses for trigger on image acquisition board.

I am new to the concept of external triggering of events. I am trying to figure out how to use the trigger on an image acquisition board (specifically - I have the pci-1411). I am wondering if I can use the trigger for things that have nothing to do with image aquisition. I don't necessarily want to acquire an image when the board receives a trigger signal. I would like to use the board to detect that trigger signal, and, when it does, execute a particular set of code. Can this be done?
Also, I am wondering if the IMAQ image acquisition boards that are capable of generating a signal through this trigger (I understand that the pci-1411 cannot generate a signal?) could be used to control some external device like a s
mall motor for example.
Thank you for your help.

Kindly refer,
http://zone.ni.com/devzone/conceptd.nsf/webmain/BF9C43586430C32B86256BFB00528558?opendocument
http://search.ni.com/query.html?col=alldocs&qp=%2Bcontentformat%3Asoftwarelib&layout=SoftLib&qt=%2Bimaq+trigger+pulse
The pulse that the imaq board generates is not meant to drive motors. For that we have motion cards, refer, ni.com/motion
http://zone.ni.com/devzone/conceptd.nsf/webmain/66E6F4EE7E0848D686256A550060C436?opendocument
IMAQ Generate Pulse - This function allows you to generate a pulse from the TIO chips on the board. This functionality is only supported with the 1409 and the digital boards (1422, 1424, 1428). You can only drive at most two pulses at once. Driving pulses doesn't require events, unless you are triggering the pulse off o
f the Frame Start or Frame Done.
IMAQ Trigger Read - This function allows you to read the status of External Trigger lines or RTSI lines.

A better way to get current and previous status?

I'm working on a system where status messages are read into a table for items of equipment. My requirement is to find all the messages arriving within a particular time window, together with the status value and the status value for the previous message sent for that equipment item, if any. This previous message can (and probably will) have a date outside the window I'm looking at, or might not exist at all for a brand new equipment item.
The table looks something like this:
create table eq_state
(eq_id NUMBER, -- ID of the equipment
event_date DATE, -- Date/Time of the message
status NUMBER) -- Status passed in the messageThere are indexes on (event_date,eq_id) and on eq_id. It'll get very big, so it's important that indexes are used wherever possible.
Here's what I have so far:
WITH eq_state AS
SELECT 1 eq_id, TO_DATE('01/05/2013 12:01:00','DD/MM/YYYY HH:MI:SS') event_date, 1 status FROM DUAL
UNION ALL
SELECT 2 eq_id, TO_DATE('01/05/2013 01:01:00','DD/MM/YYYY HH:MI:SS') event_date, 2 status FROM DUAL
UNION ALL
SELECT 2 eq_id, TO_DATE('01/05/2013 12:02:00','DD/MM/YYYY HH:MI:SS') event_date, 3 status FROM DUAL
UNION ALL
SELECT 3 eq_id, TO_DATE('01/05/2013 10:00:00','DD/MM/YYYY HH:MI:SS') event_date, 4 status FROM DUAL
UNION ALL
SELECT 3 eq_id, TO_DATE('01/05/2013 12:03:00','DD/MM/YYYY HH:MI:SS') event_date, 5 status FROM DUAL
UNION ALL
SELECT 3 eq_id, TO_DATE('01/05/2013 12:04:00','DD/MM/YYYY HH:MI:SS') event_date, 6 status FROM DUAL
SELECT eq_id,TO_CHAR(event_date,'DD/MM/YYYY HH:MI:SS') event_date,curr_state,prev_state
FROM (SELECT Es.Eq_Id,
 Es.Event_Date,
 Es.Status AS Curr_State,
 Es2.Status AS Prev_State,
 RANK() OVER (PARTITION BY es.eq_id,es.event_date ORDER BY es2.event_date DESC) the_rank
 FROM Eq_State Es
 LEFT OUTER JOIN Eq_State Es2
 ON Es2.Eq_Id = Es.Eq_Id
 AND Es2.Event_Date < Es.Event_Date
 WHERE Es.Event_Date BETWEEN TO_DATE('01/05/2013 12:00:00','DD/MM/YYYY HH:MI:SS')
 AND TO_DATE('01/05/2013 12:05:00','DD/MM/YYYY HH:MI:SS')) x
WHERE the_rank = 1
ORDER BY 1,2This gives me the desired results and seems to use sensible indexes (I'll spare you the explain plan):
 EQ_ID EVENT_DATE CURR_STATE PREV_STATE
 1 01/05/2013 12:01:00 1
 2 01/05/2013 12:02:00 3 2
 3 01/05/2013 12:03:00 5 4
 3 01/05/2013 12:04:00 6 5So what's the problem? Just curiosity really - the technique of finding the RANK() in the inline view, and then selecting rows where it's equal to 1 seems like a bit of a kludge. Is there a more elegant way to do it? Maybe something using LAG() or KEEP DENSE_RANK LAST?
I'm still not really up-to-speed with analytic functions, so I'm hoping to learn something from those of you that are!
ORACLE 11.2.0.1.0 by the way

I would use another way, firstly sorting by any unique criteria and using joins
WITH eq_state AS
SELECT 1 eq_id, TO_DATE('01/05/2013 12:01:00','DD/MM/YYYY HH:MI:SS') event_date, 1 status FROM DUAL
UNION ALL
SELECT 2 eq_id, TO_DATE('01/05/2013 01:01:00','DD/MM/YYYY HH:MI:SS') event_date, 2 status FROM DUAL
UNION ALL
SELECT 2 eq_id, TO_DATE('01/05/2013 12:02:00','DD/MM/YYYY HH:MI:SS') event_date, 3 status FROM DUAL
UNION ALL
SELECT 3 eq_id, TO_DATE('01/05/2013 10:00:00','DD/MM/YYYY HH:MI:SS') event_date, 4 status FROM DUAL
UNION ALL
SELECT 3 eq_id, TO_DATE('01/05/2013 12:03:00','DD/MM/YYYY HH:MI:SS') event_date, 5 status FROM DUAL
UNION ALL
SELECT 3 eq_id, TO_DATE('01/05/2013 12:04:00','DD/MM/YYYY HH:MI:SS') event_date, 6 status FROM DUAL
), sorted as (
select row_number() over (order by a.event_date) as rn, a.* from eq_state a
select * from sorted s1
left join sorted s2 on (s2.rn = s1.rn -1)
order by s1.rn

When building a vacation leave holiday system using SharePoint Foundation 2010 and SharePoint Designer workflows how can I add half day functionality?

Hi,
I have built a vacation leave holiday system for SharePoint Foundation 2010 using SharePoint Designer workflows and Javascript. Everything works perfectly but I'm struggling to design a solution for users to specify half day requests that span over dates
greater than 1 day, i.e. my half day solution works but only when the start and end date are the same. How would I change the user interface to allow users to choose which day they want the half day to be requested when the vacation leave holiday request is
from, say, 6th - 10th Jan 2014?
Thanks.

Hi ,
I have a test on my machine with a custom approval workflow and it can work normally .Here are the detailed steps :
1.
Open the site in SharePoint Designer .Create a workflow to associate with the document library .Set the workflow to start when an item is created and when an item is changed
.Also allow the workflow to start manually .
2.
Choose ‘Collect Data from a user’ .
3.
Click on the data and give a name to the Task created .
4.
Define the custom form field name as ‘Approve ?’ .Set the information type as Choice .
5.
Set the choices as ‘Approve’ and ’Reject’ .Display as Checkboxes .Uncheck the ‘Allow fill-in values’ and ‘Allow blank values’
.Click finish to save .
6.
Click on users and add the users who will approve the documents .
7.
Keep the output to variable as collect .
8.
Add a new step .Choose ‘If any value equals value ’ .Set the any value ‘Data source’ as workflow variables and parameters .Set the ‘Field
from source’ as Variable: collect .
9.
Set the value behind ‘equals ’ as ‘Approve’ .
10.
Add a new action ‘Update list item ’ .Set the item as current item .Add the field Approval status as Approved .
11.
Add an Else-if branch to update the Approval status as Rejected .
12.
Publish the workflow and test in your site .
Thanks,
Entan Ming
