How to append data in same log after start and stop signal express

how can i append my data to the same log file after starting and stopping the signal express ? Is there some option to do this. After start/stop it always makes a new log file. How can append datat to the same log file.
Thanks in advance.

Hello mbhatti,
I founded a KB which seems do describe the way to solve your problem.

Configure Logging VI start and stop without losing or dropping data

Hi there,
I am currently using a M-series PCI-6280 and a counter card PCI-6601 to do measurements on Labview 2010.
I have 3 tasks set up, 2 linear encoder counter tasks on the 6601 and 1 analog input task with 4 x inputs on my 6280. These are all timed with a counter on the 6601 through an RTSI line.
On all of these tasks, I have a similar set-up as the picture in http://zone.ni.com/devzone/cda/tut/p/id/9574 except they are all set up as "Log" only and "create/replace" file for the configure logging.vi.
Since I want to have the encoders continuously locate my position, I never "stop" the counter tasks. However, I need to use the data acquired after every move along the path to obtain and process the location and the subsequent analog input data points I have. What I have done, is I would "stop.vi" my sample clock on the counter, then open the tdms file, read the tdms file, get the array from there, close the tdms file, then "run.vi" the sample clock on the counter. However, I found when I stop the sample clock, not ALL the data points have been streamed into the file.
For example, say I move my carriage to 100mm to the right while logging, then stop the sample clock, obtain the array from the tdms file, find the size of this array called "X" for future use. Then, I move the carraige back to the origin WITHOUT starting the clock again. THEN I start the sample clock again and move 100mm towards the left. After this is done, I again, stop the sample clock and obtain the data from my tdms file starting the offset of read at "X+1". I EXPECT that this array SHOULD start at 0 then move on to 100mm to the left. However, what it does, is I see the data start at 100mm from the right for a few data points, then JUMPS to 0, then moves to the left as expected.
I propose that this means that when I stop the sample clock, the data from the counters (buffer?) have not all been streamed to the tdms file yet, and when I start the clock again, the remaining gets dumped it. Here, I am confused since I thought that "configure logging.vi" streams directly into the file without a buffer.
I was wondering if I am doing anything wrong, expecting the wrong things, and if there is a way to implement what I want. As in, is there a way to flush the remaning data in the "buffer" (i tried the flush tdms vi, but that didn't work and I didn't think it was relevant) after I stop the clock or something like that, or is my implementation competely off.
Thanks for reading,
Lester
PS. Having a way to read the most recent point from the counters would be awesome too. However, everytime I set the offset/relative to most current, it says that I cant do that while logging, even though I saw a community post saying that it works with analog inputs. Maybe this is off topic, but yeah, currently I'm just trying to get the arrays from tdms working, THANKS!
Solved!
Go to Solution.

Hello, Lester!
There are a few solutions for you here.
First, since you don't need the excess data points, you can set the "DAQmx Read" Property Node to "Overwrite" any data from previous acquisitions.
To do this, first select a "DAQmx Read Property Node" from the functions palette. The first property should default to "RelativeTo." Click on this, and instead select "OverWrite Mode" (see attached). Next, right-click on the input, create constant, and select "Overwrite Unread Samples" from the drop-down enum. After wiring the other inputs and outputs on the node, This should accomplish what you're looking for. If for some reason it doesn't, consider the following options.
Your second option is to limit the buffer size. If you know how long you want to acquire data for, you can use the sampling rate (it looks like 5000Hz, in your case) to determine the number of samples to acquire. Simply use the "DAQmx Buffer Property Node" and input the number of samples desired. When the required number of samples is acquired, the buffer will begin to overwrite the old samples. This, of course, is not a very flexible method, and obviously requires a pre-set number of data points.
Your final option is to do a brute-force open and close of your task with each acquisition. Simply use the "Clear Task" and "Create Task" functions with every new set of data desire. This should clear the buffer, but will be fairly slow (especially if you eventually change your program to take many sets of data very quickly).
As mentioned, the "OverWrite" property in the "DAQmx Read" node should take care of this for you, but feel free to try the other options if they better suit your needs.
Let us know if you have any further questions!

How to create a clock with: a reset, start and stop

How can i create a clock that have to do the following thing:
Countdown visual in the screen
Timeset with day's in seconds
- Pressing start -> it start to run
- Pressing stop -> The clock is stopping but it keeps the time, when i press start again then it goes on with counting
- Pressing Reset -> the clock goes back to the start position and waits to start again.
Tia, William
Running with Labview 6.1
Fieldpoint hardware

The key is to use a shift register to hold the previous count...
Attached is a quick and dirty version of what you describe. It displays the passed time as seconds so if you need it to be in days just divide the value by 86400...If you don't need sub-second updates you can increase the wait time.

Painfully slow data transfer on Airport Extreme (Start and stop over 6 hours for 200 megs)

I've had my airport extreme set up for 2 years with 2 hard drives attached for my files. I have never had a problem with transferring to them until this morning. I have been unable to transfer anything to the drives at all. Every file I have attempted starts, will get about 10% through the transfer (regardless of size) and hang. I left one file "transferring" to see how long it would take - a 183 meg file took over 6 hours!
I have restarted the APE, the drives, the computer and check all connections. Nothing has changed from yesterday to today.
I don't even know where to begin with trying to figure out this issue. Can someone please help?

The new Airport Extremes and Time Capsules suffers from terrible performance over the 5GHz band and it's a problem that not only affects me and you, but hundreds of thousands of other owners.
Nobody knows if it's a firmware problem or the Marvell chips inside that's the problem, and Apple hasn't said or done anything for months.
I'm still hoping for a firmware update to solve this, but if it doesn't get fixed soon enough, I'm gonna return it and go back to backing up to wired disk and my rock solid Airport Express.
Not the happiest answer, but at least you have a clue now.
Cheers,
Koski

How to Select data using same column name from 3 remote database

Hi,
Can anyone help me on how to get data with same column names from 3 remote database and a single alias.
Ex.
SELECT *
a.name, b.status, SUM(b.qty) qantity, MAX(b.date) date_as_of
FROM
*((table1@remotedatabase1, table1@remotedatabase2, table1@remotedatabase3)a,*
*(table1@remotedatabase1, table1@remotedatabase2, table1@remotedatabase3)b)*
WHERE b.dept = 'finance'
AND a.position = 'admin'
AND a.latest = 'Y' AND (b.status <> 'TRM') AND b.qty > 0;
GROUP BY a.name, b.status ;
NOTE: the bold statements is just an example of what I want to do but I always gets an error beacause of ambiguous columns.
Thanks in advnce. :)

Each object must be uniquely identified. So you cannot do this:
select * from (table1@remotedatabase1, table1@remotedatabase2, table1@remotedatabase3) a3 objects cannot share the same alias. Example:
SQL> select * from (dual, dual) d;
select * from (dual, dual) d
ERROR at line 1:
ORA-00907: missing right parenthesisYou need to combine the objects - using a join or union or similar. So it will need to be done as follows:
SQL> select * from (select * from dual d1, dual d2) d;
select * from (select * from dual d1, dual d2) d
ERROR at line 1:
ORA-00918: column ambiguously definedHowever, we need to have unique column names in a SQL projection - so the join of the tables need to project a unique set of columns. Thus:
SQL> select * from (select d1.dummy as dummy1, d2.dummy as dummy2 from dual d1, dual d2) d;
DUM DUM
X X
SQL> I suggest that you look closely at what scope is and how it applies in the SQL language - and ignore whether the objects referenced are local or remote as it has no impact to fundamentals of scope resolution.

You can not access the backup directly.
Did you restore your replacement from this backup?
If so then you already have everything in the backup on your device.
If not, you can wipe the device and restore from this backup:
Settings > General > Reset > Erase All Content & Settings
What is it you are worried about losing that isn't already on your current device?

How to copy only part of a binary file after selecting a start and stop byte?

I need to copy a selectable block of binary data from one file to a new file. The binary file is made up of several data widths (8/16/32 signed and unsigned). If I use a read binary function I will need to account for the data types within the file. I was hoping to do a copy function with a start and stop byte control. Any pointers?

The attached Rube Goldberg Code copies two arrays of clusters to two arrays of indicators.
Ben
BTW: It does so by writtng the flattened data to a fixed length file and decoding same on the read.

Not precisely that way, but just off the top of my head, you would have to have a handle to the proccess (server) in the first window, then have a monitor program that allows you take this handle and end it. I would make this monitor program be the gateway to starting and stopping your server. To run a .bat file you can use runtime.exec().

How to use counter as an start and stop trigger in 6009

Hi ALL.
I'm using USB 6009 as a subject of to acquire data.
I would like to know on how to use the counter digital input as a start and stop trigger.
The acquisition will only start when the first pulse of the digital signal is received and it will stop when the desired number of pulse is received.
I was trying to use the VI as attachment as my reference. However, after tried, the VI is not working for USB 6009 as the counter input cannot be used as a trigger.
I would be happy if anyone could suggest me some ideas on this matter.
Thanks.

DigitalStartandStopTrigger.vi ‏32 KB

Hi Kate.
Thanks for your response.
For your information, I've design my VI using the counter method. However, it doesnt work well. Please see the figure below. The file also attached with this reply.
At first, the first counter from Device 2 will start counting. If the counting equal 0, then the acquisition for Device 1/AIO also the counter of Device 1/ctr0 begin acquiring data and counting the edges respectively.
However, when I did the test, it doesn't work as wanted. It is happened because when counter of device 2 in not equal to 0, the acquisition for Device 1 not happened as it will go to false state.
Is there anything that someone could suggest on how to start the acquisition for device 1 only and if the counter of device 2 is equal to 1. I would like the acquisition of device 1 start only when the counter of device 2 is equal to 1. I cannot use the trigger as 6009 is not support for it.

I am trying to free my mac book for space. everytime i try to empty the deleted items in trash, it starts and stop without clearing the items. how do i empty the trash

I am trying to free my Mac book for space in oredr to upgrade. Everytime i try to empty the deleted items in the trash, it starts and stops immediately without clearing the items. How do i achieve this?

I had the same problem yesterday with an application file that was deleted after installation of an update. I used "Put Back" to move it back to its original location, then used "Show Package Contents" to delete/empty trash for small groups of files at a time. I suppose the application file itself may have been too large to empty at one time. I hope this helps.

How to Start and Stop Processes?

How to Start and Stop Processes?
Im trying to create a program which allows me to Start and Stop (and Restart) GameServers. I will then expand on this so i can start and stop them through a web applet with build in useraccounts.
Currently the way we do this is to log into the server using a RemoteAssistance. Which is not very safe as the users have the abbility to do anything on the server and potentially corrupt it.
Below is my code for how i start the servers. But i dont know how i would stop the process.
