How to switch multiple relays using PCI 6601 DAQ card

What is the specification of the digital output value given from the PCI 6601 DAQ card?How to develop LAB VIEW code to switch a relay?Can anybody please explain?

Hi hasi,
did you read the manual and the specs of the PCI6601? It says: "5V TTL/CMOS compatible"...
You shouldn't expect to much current from a simple DO pin - probably it's not enough to drive your relay!

I need to read multiple counters using PCI 6601 can I do this, and How?

I am reading 4 TTL signals from a Magnetic Pickup how do I read multiple channels using PCI 6601?

Not concerning my primary question, I would like to point out to an N.I. Rep. that there is a typo in the help section concerning "posting a message".
I have built a large format, two axis digitizer using linear encoders, a 6601 counter/timer, and labview 8. In building my application program, I initially am using two daq assistants, with each set up to accomplish the task of reading two encoders simultaneously. In doing some research, It has come to my attention, that, with my current configuration, errors may result, due to one daq assistant attempting to access the cards driver while the other is acquiring data. All attempts to get two channels working through a single daq assistant have resulted in an error message informing me that I can only have one task per counter.Thus far, I have not seen any noticeable errors, thought I would like to have this device "rock solid", as it will be used extensively.
Is it possible, that I should have purchase an "S" series board instead?

Noise in thermocouple measurement using PCI-6024E DAQ card

I am using a PCI-6024E DAQ card for thermocouple(TC) measurement. The
TC is installed in the mold cavity of an injection molding (IM)
machine. The leads from the TC are connected to the DAQ card using a
CB-68LP board. I made a temperature mesurment task in LabView 7.0
with the two leads from TC as differential inputs and used CJC value of
25 deg C.
The problem is that when the IM machine is OFF, I get a reasonable temp
reading with some slight noise but as soon as I turn ON the IM machine,
the temp readings go wild with a lot of variations around the mean
value. The temp values also don't go to higher values when the TC is in
contact with the molten plastic in the IM machine.
Do I need to ground something here or put a resistor in the I/O board?
BTW the IM machine is grounded and the TC give correct temp values when
connected to a hand-held temp reader.
Any help will be highly appreciated.

Hello Aftab,
Looks like you need to use bias resistors to reduce the noise. Check out the following tutorial for more information about how to use bias resistors.

What is the maximum number of samples that can be acquired with a single trigger using PCI-6036E DAQ card?

1. My PCI-6036E card has a FIFO of 1024 bytes in AI. Maximum how many samples can be acquired with single trigger for digitizing a waveform?
2. PCI-6036E DAQ card has got a AO with 10ks/s update rate? Can I generate a pulsed output with the AO of this card? I need a pulse of, say, 5 V and 1 kHz frequency.

Giri,
1.The trigger is usually for enabling the acquisition. I mean, when it is logic zero, you acquire nothing; however, when it is logic one, you start acquiring your waveform,and you can acquire continuously without having to worry about how many samples, unless you want to set your program for doing so. You can acquire continuously by implementing buffer acquisition. Finally, the FIFO that is in the board will not affect the buffer acquisition.
2.Yes, you can do that! You can generate your 5V signal with that specific frequency, and you should not have any problems, because the freq fits in the update rate.
I hope this information is helpful.

32 bit I/O using PCI-6533 DAQ card

I am thinking of purchasing the PCI-6533 DAQ card and need to know if the the 32 bits can be configured individually as input or output. I know that they can for unstrobed and static applications but I need to be using strobed or non-static. I also know that the you can set the 8 bit ports as input or output ports for highspeed. So my question is... Can I configure each individual line as input or output for highspeed applications?

Hi,
Unfortunately, the 653x boards can only be configured on a line-by-line basis for asynchronous digital I/O.
When in synchronous pattern acquisition/generation mode, the 653x is divided into 2 groups (2 ports in each group). These two groups can be operated independently as input or output and at different clock frequencies. However, all lines on both ports of a group are configured in the same way.
If you are looking for completely individually controlled lines in a pattern generation/acquisition application, you might consider the new high-speed digital board (NI 655x).
Hope that helps. Have a good day.

Need an enable/disable Labview VI for SC-2062 relay board using PCI-6503 DAQ Card.

I am using Labview 6i, and I need to write an enable/disable VI that will enable and disable 6 of the 8 relays at any time while keeping the whole vi running. Therefore one or more positions may be changed at a time, but positions that don't change cannot be interrupted when changing others (no port resets allowed). I was wanting to maybe send a 1 by 6 array of some sort out but I can't figure out how to use the array to communicate with the DAQ card, relay board and SC-2051 adaptor. There also needs to be error handling in and out. Thanks for your help. Any examples would be very helpful.

Hello;
The best way to go about that is to disable the data points correspondent to the channels you want to disable. Meaning that you can ignore the datapoints of the channels you want to disable on the fly. That is the only way to disable channels on the fly.

Thanks!

hi childs,
is there any graphic card switch button? also, have you tried to disable/activate the graphic card in bios?

Measuring the frequency using PCI 6221 Daq card

Hi
I want to find the frequency of an external signal.
How can i do that give me some idea or example.
Regards,
Hari

If you need to capture the waveform look at the aquire waveform examples and add the
Extract Single Tone Information VI
Owning Palette: Waveform Measurements
VIs
Requires: Full Development System
Takes a signal in, finds the single tone with the highest
amplitude or searches a specified frequency range, and returns the single tone
frequency, amplitude, and phase. The input signal can be real or complex and
single-channel or multichannel. Wire data to the time signal in
input to determine the polymorphic instance to use or manually select the
instance.

I am trying to sample 2khz signal at 8khz,with an accuracy upto 6place of decimal ,using pci 1200 DAQ card.

how can i externally trigger this operation.i need to sample my signal at 4 points and store it in a excel sheet and the values should be same,as the the 2khz signal and the 8 khz signal both are comming from the same source.

could u tell me what more details would be required....i will be more than glad to let u know about it.

PCI-6023E DAQ card maximum sampling frequency

Hello
I am using PCI-6023E DAQ card in pc-based ETS solution (and writing appilication in LabView 7.1 with RT module). The card has 200kS/s maximum sampling frequency, but it can be set for much higher sampling frequencies and the waveform acquired appears to be correct (i.e. i've tried setting it fo 1MS/s and sampling 400kHz sine, which is obviously above Nyquist frequency for 200kS/s card, but on spectral graph, main peak is at 400kHz). Is the card driver doing some kind of free/coherent sampling?
Moreover, when sampling frequency is set to 200kS/s, the card seems to be doing same thing - i.e. for 200kS/s and sample block size of 200kS, graph should be updated once in a second, but it's updating slighty slower.
I'd really appreciate if someone could explain me (or gave me a link to materials) what exactly is happening here? Is driver doing some background work, or maybe it is problem with network latency/unstability ? What is the impact of this effect on real-time aquisition?
Thanks in advance
Jan Kienig

Since the fundemental is 4 times the nyquist, then what you are measuring is an alias of the fundemental. This works well as long as the fundemental is a repetitive signal. Sampling every other peak and every other node looks the same as sampling every peak and node. Tektronix exploited this on their 7S series sampling heads. Another use of this phenomena is the effective demodulation of high frequency signals as long as the bandwidth meets nyquist. As with your card, if the input amplifier supported it, I could extract modulation information from a 500 MHz signal so long as the the bandwith of that modulation did not exceed 100 kHz.

How to get multiple records using fn-bea:execute-sql()

Hi,
I created Proxy service(ALSB3.0) to get records from DB table. I have used Xquery function(fn-bea:execute-sql()). Using simple SQL query I got single record, but my table having multiple records. Please suggest how to get multiple records using fn-bea:execute-sql() and how to assign them in ALSB variable.
Regards,
Nagaraju
Edited by: user10373980 on Sep 29, 2008 6:11 AM

Hi,
Am facing the same issue stated above that I couldnt get all the records in the table that am querying in the Proxyservice.
For example:
fn-bea:execute-sql('EsbDataSource', 'student', 'select Name from StudentList' ) is the query that am using to fetch the records from the table called StudentList which contains more than one records like
Id Name
01 XXX
02 YYY
03 ZZZ
I tried to assign the result of the above query in a variable and while trying to log the variable, I can see the below
<student>
<Name>XXX</Name>
</student>
I want to have all the records from my table in xml format but it's not coming up. I get the value only from the first row of my table.
Please suggest.
regards,
Venkat

How to upload multiple files using wicket

Hai,
how to upload multiple files using wicket at a single browse.
any suggestion?
Thanks in advance

You have to do this your self by either (as vinod said) using a different component (not present in adf) or implementing this:
1) allow the user to select multiple filenames (somehow)
2) zip them together
3) upload the zip
4) unpack the zip on the server
5) work with the files

How to retrieve multiple columns using "returning" in the Insert query.

hi,
wanted to know how to retrieve multiple columns using "returning" in the Insert Query.
For retrieving one column we write the query as follows:
Insert into TABLE values(1,2,3,4) returning COLUMN1 into PARAMETER
But can we retrive multiple columns in the same query?
am using oracle 10g and coding in .NET

Hi,
You can definetely get multiple values from a single query using the 'returning' clause.
Eg : insert into emp (empno, ename, job, deptno) values (7324,'ADAM','MARKETING',30) returning ename, deptno into var1, var2; PN : var1 & var2 to be declared as varchar2 & number respectively.
More insight into the 'RETURNING' clause in this link.

Could I use PCI-6601 to generate a 200Hz clock based on a external 40kHz clock?

Could I use PCI-6601 to generate a 200Hz clock based on a external 40kHz clock?
That means I want to use PCI-6601 as a frequency divider. (40KHz->200Hz)
Is it possible? Is there any example I can refer to?

1. Yes it's definitely possible to make such a frequency divider.
2. Here are a couple links that may help:
