How to graph the counter frequency

Hello, does anyone know how to make a graph from a frequency signal that comes from a counter?
It seems that I first need to convert the frequency signal (scalar) into a waveform type.
I do not know how do this. Any suggestions for me?
As a basis I use the "Meas Dig Frequency-Low Freq 1 Ctr.vi" example from NI for the frequency measurement.
Thanks,
Peter

Peter,
I can't look at the example you mentioned from the PC I'm at now, but I can describe the way I've always done it.
I'm assuming that the incoming frequency varies, and is calculated by timestamping the incoming edges. This would mean that the hardware is doing something like period measurement and the sample rate varies with the varying periods. Such data wouldn't be suitable for the waveform datatype which assumes a constant interval time dt.
I would recommend graphing on an XY Graph. The Y data is your frequency array. The X (time) data is derived from it pretty simply. First send your frequency array through a 1/x function block to create an array of individual interval times. Then perform a cumulative sum of the interval array to produce a Time array for your X axis.
The cumulative sum can be obtained with a For loop with a single shift register initialized to 0. Auto-index the loop with the interval array. Sum each element with the left-hand shift register value. Send the sum to both the right-hand shift register and to an auto-indexed output for cumulative time.

How to convert the counter input as a RPM

Hello NI,
Could you tell me. how to convert the Counter input to the RPM. I am using Rotary encoder has a 5V amplitude with 500 PPR. i am going to measure the Engine speed as a rpm.
I am using third party hardware, from the hardware i can get the Count as well as Frequency also.
Could you suggest to me...? i looked out some disscussion in these forum but i cant able to understand.
can you please explain with simple way....
if you have any simulation send me....

If you're able to read frequency as X pulses/sec(?) that seems to convert RPM as follows:
X (pulse/sec) * 1/500 (rev/pulse) * 60 (sec/min) = X * 60/500 RPM (???)
Cheers!

How to make the counter count or start at different time

Hi,
How to let the counter count the time, that doesn't start at the same time ?
This timing system is a sport timing system for canoe competition, it need to track 6 competitor that start at different time .
I have a problem , I have 6 counter in a VI that use to track 6 competitor, but it start count at the same time, how to make it count separately for each competitor ?
Do you guys know how to solve this problem ?
Solved!

HI,
ya, i run it. I mean i know how to make it to 6 competitor already , and yes, it works but the time, it still count or start at the same time. I need to run each competitor at different time , like this competitor A 20-2-2012.VI . This is the one i do but it cant put a stop button. once i put a stop button, the clock stop counting but the whole VI is running.
Regadrs,
Sam

How to get the count of each minutes

Oracle 10 DB
Hi All
I using this query to get the count of records fetched by the concurrent program per min,
select count (distinct b.attribute2)
from oe_order_headers_all a,oe_order_lines_all b
where a.header_id=b.header_id
and b.flow_status_code ='AWAIT_QUINTIQ_BOOK'
and to_Char(b.last_update_date,'DD-MON-YYYY HH24:MI:SS') between '19-JAN-2011 02:00:01' AND
'19-JAN-2011 02:00:02'
This is used to get the count of records fetched at one mins
How to find the count of last 10 mins ie 1 mins count 2.00 to 2.10
Thanks & Regards
Srikkanth.M

Try this:
SELECT TRUNC(b.last_update_date, 'mi') time_mins, COUNT(DISTINCT b.attribute2)
FROM   oe_order_headers_all a,
       oe_order_lines_all b
WHERE a.header_id = b.header_id
AND    b.flow_status_code = 'AWAIT_QUINTIQ_BOOK'
AND    b.last_update_date >= to_date('19/01/2011 02:00:00', 'dd/mm/yyyy hh24:mi:ss')
AND    b.last_update_date < to_date('19/01/2011 02:10:00', 'dd/mm/yyyy hh24:mi:ss')
GROUP BY TRUNC(b.last_update_date, 'mi');I'm not sure why you're bothering with the join to the oe_order_headers_all table, since you're not referencing that in the where clause or the selected columns list. I think you could probably do away with it.
I've changed your code to take the last_update_date and truncate it to the minute level, and added that as a column, so you can see which count goes with which minute. Obviously, this has to be in the group by.
I've also changed your date comparisons so that you're actually comparing dates to dates, rather than strings to strings - why would you deliberately take information away from the optimizer? Oracle does not treat strings the same as dates, and forcing it to use strings rather than dates could lead you to have a vastly differing execution path, which will most likely be less performant.
Not to mention, coding like that leads you to assume that you can compare dates in strings without any problems, and that is just not the case. '19-FEB-2011' is counted as being earlier than '19-JAN-2008', as strings sort alphabetically.

How to find the count of tables going for fts(full table scan in oracle 10g

HI
how to find the count of tables going for fts(full table scan) in oracle 10g
regards

Hi,
Why do you want to 'find' those tables?
Do you want to 'avoid FTS' on those tables?
You provide little information here. (Perhaps you just migrated from 9i and having problems with certain queries now?)
FTS is sometimes the fastest way to retrieve data, and sometimes an index scan is.
http://asktom.oracle.com/pls/asktom/f?p=100:11:0::::P11_QUESTION_ID:9422487749968
There's no 'FTS view' available, if you want to know what happens on your DB you need, like Anand already said, to trace sessions that 'worry you'.

How to stop the counter after getting maximum amplitude from a waveform graph?

I am using accelerometer, optical encoder and daq card (PCI MIO 16XE10) for my tyre balancing project. Basically i am trying to stop my edges count from the optical encoder to get the position for putting the mass for correcting the balancing. Could anyone please help me by telling me how i can achieve it or is there any other ways to get the position using the daq card? One more thing, could anyone tell me how to change the waveform graph to frequency domain instead of time domain?

Time to Freq is easy. 1/time = freq. example. 1 msec period = 1000 hertz (1kHz).
I guessing you are attempting to design a new spin balancer for tires. I would record the entire "spin cycle with index count" then search the resulting waveform for the max amplitutes. Correlate the indexes and that should give you the high point and location. You might want to count the number of revolutions, then grab that 60% of that number of peaks.

WM RF Inventory : how to change the counting.

Hello every body,
We are using transaction LM50 and LM51 for the WM inventory counting with radio frequency terminals.
My question is how is it possible the change the counting for one material in one bin ?
The situation is that we have big bins with several material in it. When I count for 1 material in 1 bin, sometime I can find the same material in an other part of the same bin. Then I need the change the counting, but I don't know how to do it.
One other solution would have been to add a new item (using F7), to add the product again, but it's not possible because the same material is already in that bin...
If someone has an idea, it would really help me.
thank's !!
Mathieu.

How you change the download frequency for a single Podcast?

I have iTunes 11.1.5 for Mac, and I can't find how to change the down load frequence , aka "check for new episodes" setting for individual podcasts. I've tried using the settings menu in the "My Podcasts" and the "List" podcast view. When I do this, I see these setting:
Keep
Download
Sort Order
Play Order
If I click on the "Defaults..." button, the top setting is "check for new episodes"
I have no problem with being able to change the default download frequency setting, but I am at wit's end with locating where I can change that setting for individual podcasts.

How to get the count of repeating elements in a xml doc.

In many xml documents, in is common to have repeating child elements and what I would like to know is how do I determine exactly how many of these child elements exist in a particular document. There is probably a correct XPath string to determine this, but I cannot figure out what it is. Here is an example
<a>
<b>
<c>1</c>
<c>5</c>
<c>22</c>
</b>
</a>
The above 'c' element is what varies in number from document to document and I need to know how to get the number of 'c' elements for the document, which would be 3 in the above case.

create table test_xml(data xmltype)
insert into test_xml values(
xmltype('<a>
<b>
<c>1</c>
<c>5</c>
<c>22</c>
</b>
</a>')
select extract(data, '/a/b/c').getclobval() from test_xml
select count(*) from test_xml
where existsnode(data, '/a/b/c')=1
good luck.

Select Count(*) from Sample_table - how to get the count using JDBC?

Hi All,
It would be glad if anyone could help me with this. The problem is that I have to get the 'count' of records selected from a arbitrary table say, 'sample_table'. Is that possible to form the SQL in JDBC as
Select Count(*) from Sample_table
and get the value of the count? If yes, how?
Thanks in advance
Prabz

stmt = con.createStatement();
ResultSet recordcnt_rs = stmt.executeQuery("Select Count (*) as record_ctr From Sample_table");
recordcnt_rs.next();
record_ctr = recordcnt_rs.getInt("record_ctr");
hope this helps.
