NI PCI 6221 and SCB-68 and timer

I'm using NI PCI 6221 and SCB-68. Can I use timer with Single Two-Signal Edge-Separation Measurement. Is this type of measurement can be set with that hardware combination. I,m asking becouse when I,m using DAQ ASSISTANCE it pointing the pin name that doesn,t exist on the SCB-68.

Hi Fazi,
The SCB-68 has pinout labels for E-series DAQ cards while the NI PCI-6221 is one of the newer M-series DAQ cards. The Single Two-Signal Edge-Separation Measurement you want to take is possible with your card. Below is a KnowledgeBase article which gives the SCB-68 pinouts for M-series cards. Let me know if this fully answers your question or I assumed something wrong.

How can I configure NI PCI 6221 and DAQ SCB-68 for pressure sensors?

Hello
everybody,
I am using the measuring board (NI PCI 6221) and DAQ
SCB-68 for the data acquisition.
With the DAQ-Assistant I created AI for the voltage of
pressure sensors. In a big indicator panel from this DAQ-Assistant I see the
voltage for both sensors in the correct size. But if I set sensors in the
blockdiagramm to control the signals for sensor one I get a wrong voltage size
and for sensor 2 nothing.
How can I configure this data acquisition equipment to
get the correct signals?
Thanks a lot for your help.

I do not know the type of sensor you are using. But pressure transducers may have a very low output voltage(in the mVolt range). They also need an excitation voltage. Here is an introduction. http://focus.ti.com.cn/cn/lit/an/sloa034/sloa034.pdfThen working with pressure sensors I always use 3 stages in the circuit.
1 Instrumentation Amplifier as a preamp
2 filterstage
3 Final amp and output buffer
(you may combine stage 2 and 3)
Besides which, my opinion is that Express VIs Carthage must be destroyed deleted
(Sorry no Labview "brag list" so far)

All AI channels have the same value - NI PCI-6221 and NI PCI-6229

Hello,
I use the example aiex1.cpp for a multichannel AI read with the mseries devices 6221 and 6229.
This example works for one channel, but the other channels have the same value (+- 0.001 Volt difference).
For example: I set 5Volt on the first channel and then the other channel have 5Volt too.
What should I consider in the configuration?
Please, can someone help me?
Best regards,
Heiko

Hi Heiko,
Like Moritz, I'm curious what signals you have connected to your AI channels. What voltage do you expect to read on each channel?
Tom gave me your initialization code and it looks like you've modified aiex1.cpp. Does the example work without any changes?
I have some more questions that will help me determine where the problem could be coming from, but these two are the easiest. We'll keep getting more and more specific as we remove possible causes.

Using timer/counter with PCI-6221/USB-6210 to control timed-loop VI

Dear all,
I need to ask about two devices and one of their functionalities, PCI-6221 and USB-6210. For our NI-based system, we need to control some timings in a Timed-Loop vi, for that currently we are using PCI-6221 and we give external TTL signal (at 1 kHz) to it,
recenntly we need to make some changes and for that we found USB 6210 DAQ to be more suitable, but we need to clear ourselves on some specific things.
Can the counter/timers functions available in the either PCI 6221 or USB 6210 can be used to control the Timed-loop VI by giving external clock or by using their own internal clock source?
Although we are using external clock with the PCI 6221 but we want to know about the usage of their internal clock, also are controlling timed-loop also possible for USB-6210
Also... What if we use the RTOS, are they still able to control the timed-loop VI without giving any 'EXTERNAL CLOCK' and using the internal clock sources of the DAQs
Waiting for reply,
Bests,

Ben,
I having read previous email which I send earlier with general overview, we discussed in more detail within our team and I am giviing the specific answers.
Please check in RED the most recent answers. Blue are the questions/suggestions by your side.
1.    Using Internal hardware clock of PCI-6221 would enable us get rid of external clock, but how to divert the internal hardware clock to the current settings. Any idea (can you provide us with some reference manul for otherwise). I mean is there some flag-bit etc. or VI
2.       Is it also meant that with the installation of RTOS the timed-loop can directly get the timing source from the internal hardware clock PCI-6221? --- How???
3.       In order to make desktop to work as RT system, what is the hardware (motherboard, processor, etc..) requirement? What are the LabVIEW modules (specific name) that needed to be installed? Our platform is LabVIEW 8.6. (Currently we have windows-7 with i7 core processor)
What kind of application are you intending for this system? ---- high-speed laser scanning system.
Are you most concerned about accuracy, speed, or responsiveness? To control the laser mirror scanner to move at 1 kHz or 2 kHz speed. On the other hands, using PCI-5105 (128 MB memory) as a DAQ for real-time/on-the-fly data processing.

PCI 6221

Good day all,
Kindly assist on this. I have a PCI 6221 and a connector block BNC 2110. I am using a PCB accelerometer to acquire signal from a modeled building with the aim of getting the frequency components from the time response after exciting the building at a specific constant frequency. The problem is I kept noticing that I cannot select acceleration with PCI 6221 so I selected voltage in DAQ. The time response seems okay but the FFT is totally not worth it. I presume I should get my specific frequency back since this if forced excitation but this is not happening.
My question are
1) Since PCB accelerometer are supposed to be given a little voltage of 4A to get them started, can I use PCI-6221 the way I am using it and still acquired signal from my building which can be presumed normal.(I mean okay)
2) Is it right for me to select voltage in DAQ instead of accelerometer using PCB accelerometer when the aim is to acquire acceleration values or let me put it this way :if I cannot get a card that can read acceleration can I still used the voltage in DAQ since the PCB ICP accelerometer gives out voltage values. Please which is the right way.
Thanks all.

Hi Osmosis,
to measure acceleration using 6221 and PCB accelerometer, you need signal conditioner (480C02 from PCB) to
power sensor and decouple sensor DC offset (around 10V). You can use voltage task and scale readout according
to your accelerometer sensitivity (for instance 100mV/g). Another way is to use one of DSA cards. Consider
USB 9234 for direct connection to PCB accelerometer and measurement using acceleration task.

Pci-6221 card is not recognised with DAQ

I have installed NI DAQ 7.3 and monted a PCI-6221 and PCI-MIO 16E-4 cards. The PCI-6221 is not recognised by the software.

The card is supported by NI-DAQmx 7.3 and should be recognised by the PC without trouble. Can Windows see the card at all?
Check the specification of your PC's Motherboard. M-Series cards require the PCI bus to supply 3.3V, 5V & 12V. Some PCI slots may not provide these required voltages.
Hope this helps!

How to use scb 68(pci 6221) for voltage and current measurement

hi

PCI 6221 is DAQ card with 68 terminals and SCB (Shielded Connector Board) 68 is termination board to those 68 pins of 6221 card, so that you can connect signals (to be measured) to appropriate pin of PCI 6221. You might already aware of it.
Refer to the pin out of PCI 6221 to check which is the correct terminal, for voltage measurements.
You cannot measure current directly, instead use a resistor of known value (and appropriate current rating), let current (to be measured) flow through it and measure the voltage across that resistor.
I am not allergic to Kudos, in fact I love Kudos.

Displaying and saving multichannel waveforms using PCI-6221 DAQmx card

I am trying to obtain voltage readings at 8000 kHz from 9 channels using a PCI-6221 DAQmx card. The waveforms are to be displayed on individual charts while being saved. I have run into problems when I have 4 channels reading in at the same time. The charts stop displaying the data. Since the program will be running within another program where video acquisition is being done, space/buffer size is a very large consideration. If anyone can offer any suggestions about being able to display and save this data without losing seconds of information, the help would be appreciated.
Thanks,
Nina

Hello Nins,
The first thing to notice is that you are going far beyond the specifications of the 6221 if in fact you are sampling at 8000 kHz. Something I can tell you is that when you are performing fast acquisitions and processing the data at the same time, it is sometimes advised to have an acquisition loop (procucer loop) and a processing loop (consumer loop) and transfer data between the two. That way, you can put a wait in the consumer loop and use a waveform graph to plot the data rather than using a Chart wich requires memory.
Hope this helps some...

How to reduce reading and recording data time/ Visual C++, PCI 6024E and PCI-MIO-16E?

Right now I am working on a data communication programme. The time of reading digital signal and recording data is more than I expected, which is about 100 microsecond. I need to reduce the time. The software I am using is Visual C++ 6.0. I use two DAQ boards, which are PCI-6024E and PCI-MIO-16E. I have set the priority of Visual C++ to be realtime by task manager. The operating systme is Windows XP.
I am wondering how to set the interrupt of reading or writing data to be the highest and stop any other kind of interrupt.
Thanks in advance!

The primary limitation you will encounter when trying to do high speed
digital I/O using your E-Series hardware is that the digital lines are
all software timed. This means that for each and every digital
read it is necessary for your software to issue a command to your
hardware, read a single point, then receive the response from the
board. This prevents you from performing digital operations at
very high speed. In general, I would say that 100 microseconds is
a very good response using software-timed digital I/O on a Windows
computer.
It is difficult to make a good recommendation without more detail about
what you are trying to do. You may need to consider switching to
a Real-Time operating system, or upgrading your DAQ hardware to a board
that will allow you to time your digital acquisitions on the board
itself. These devices, such as the m-Series DAQ or the PCI-653x
series, would allow you to use hardware triggers for your digital
acquisitions, change detection, and buffered data acquisitions to
reduce the software overhead involved in a rapid acquisition.

SCB-68 & M-Series PCI-6221

I have a PCI-6221 M series (68PIN) that I want to connect to SCB-68
The manual that came with the SCB-68 (under Quick REference labales) does not show M Series Devices!
It only shows, E,S, 670X671X/673X,660X,653X and 7811R/7831R Devices.
Any idea where do I find the information for the M series devices?
Thank you

Hi,
The device pin-outs given in this manual for your PCI-6221 should match with your SCB 68 pin numbers.
As far as i know, the switch settings on SCB 68 has not changed for M series.
Plus your MAX also shows the device pinouts.
Go to device and interfaces, click on your card and select for device pinouts from the drop-down menu.
hope this helps

Data acquisition and frequency generation togather with PCI-6251 and LV8.2

Hi friends,
I am a new user of Labview. I am using LB8.2 with PCI-6251 .
I have to generate frequency and then measure the data and then for next frequency and so on.
i know that for this i have to use looping and that is not a problem. The real problem for measurement is to identify whether the frequency is been generated. if yes then measurements starts otherwise it should wait until it started. then after finishing the measurements send a signal to generator for changing the frequency and amplitude.
Now these two things {generation and measurement} togather are not working correctly for me. so i make 2 diff file, one for generation and other for measurements <by modifying the examples>. I can run both file togather and it works. But it need lots off effort and time. I have to measure from 10Hz to 1000Hz in 2Hz frequency step and i cannt leave in between .
can anyone help me how to syncronize these two togather .
Trying to attatch. both the files here ..

PCI-7334 and L298

Hi there!
Hope someone will help me with this one. I am currently working on a project that uses the pci-7334 stepper motor controller. unfortunately, i don't have any power drive with me. but i do have an UMI-7764 connector block and a L298 dual full-bridge driver. i also have some stepper motors with me but they are not of NI's. my question is: is it possible for me to used the pci-7334 to connect with the L298 and to the stepper motors using the UMI-7764? if possible, could anyone help me with the proper wire connections? thanks ahead for the response!

It is NOT that easy to drive a stepper motor, you need quite a bit more circuitry than just a plain half-bridge driver. You also have to control the current flowing through the motor winding. This is mostly done via PWM (pulse width modulation) since this method allows for using plain on/off switches which have more efficiency than an analogue control circuit. Also, using plain switches allows for running a stepper motor in full-step mode only which will yield rather rough motion/rotation.
You can enter the learning curve and design all this from scratch but it will be probably much more cost and time effective to use a ready-for-use driver. We are using drivers from IMS
http://www.imshome.com
They also offer a range of stepper motors but their drivers are compatible with most 2/4 phase stepper motors on the market, we are using them together with Phytec and Oriental motors. Their manuals are very extensive and also cover the basics of stepper motor operation and connection to drivers.

Can't access Web Site, super slowly and time out!

Hi all,
I am using Server 2012 R2 with Hyper-V, HP DL360 G6 Server
The Master OS have a NIC1 to VLAN1 Switch (Also in the Cisco SG300 Switch)
Plus other NIC2 connect to Cisco SG300 28 Switch (Running in L3 Mode), this Cisco then connect to a SonicWALL NSA 2400.
I build some VLAN31 on SonicWALL NSA 2400, and add this to the Cisco SG300 as Truck Port connect Both...
Other Port on the SG300 are untouch, so mean default running mode is Truck mode, and one of it port connect to the NIC2 to the Server ...
Ok, if Hyper-V VM, not enable VLAN in the Hyper-V Management in 2012 R2, it can take the DHCP from the SonicWALL NSA 2400 no problems, can see other LAN (VLAN1) machine well both direction, and go to Internet too.
But, if I setting the VLAN31 on Hyper Manager to some VM, it can take the DHCP and take the IP from SonicWALL for this VALN31, include DNS, GW etc...
But ... it just can ping internet, for example, ping www.yahoo.com it ok, but open IE, enter www.yahoo.com will super super slowly and time out, if running CentOS 6.5 Linux, enter yum update, it total not work, time out, 0.2kb/s etc. But it can ping to www.yahoo.com
no problems...
And If Windows run routert www.yahoo.com, over 10s to see next hub ...
I am double checked SonicWALL NSA2400 Firewall Policy is allow all VLAN and LAN to WAN, and VLAN TO VLAN too..
What is wrong on the Hyper-V VLAN? Do I am setting wrong of my switch port mode (Access/Trunking)?
I am now out of direction what is go on to troubleshooting this.
Thank you.

How can i use PCIe 1433 and basler line camera to construct image and pocess it?

hello! every one ,I am new to machine vision.i have two problems to ask.First,how can i use line camera and 1433 to acquire 2-D image?second,if i want to pocess the 1-D signal ,how can i do it ?i expect for your answer ,thank you!

What you are trying to do is not something you can easily do in a forum, but I can give you the basics.
You have a CameraLink frame Grabber (PCIe 1433) and a LineScan Camera
The framegrabber needs to be configured to understand how to communicate with the camera. You need a file from the camera vendor. This file might already be installed. You can use MAX to check if it is, under Devices/IMAQ.
Assuming you can get to the point where you can communicate with the camera, you need to configure your acquisition.
Since the camera is a line scan camera, it captures image data one pixel ine at a time. You will need to configure the frame grabber to determine how many lines per image you want. The low limit is usually 1, and the high limit is either based on the framegrabber's internal memory, or that of the computer.
If you are using labview, you will need to open a sessing to the camera, acquire the image(s), and then close the session when you are done.
Once the image(s) are captured, you can performa analysis using the NI Vision Toolkit.
Sorry, but there is no way to condense years into one post.
