• I can measure the speed of the NI 9401 fan & cRIO 9075 under Scan Interface?

  Hello

  I am currently using OR 9401 & cRIO 9075 to develop a project, which is to control the CPU fans.

  Since I have to communicate with other instruments by serial port, while I have a NI 9870 module to implement the instrument control.

  I finished the part of control instrument under scan mode and would like to add the function of the fan speed reading.

  Now, I wonder if there is a problem when I choose the Scan Interface to deverlop the program.

  I found the following tutorial, he uses the FPGA interface to impement the acquisition of control and PWM frequency.

  http://www.NI.com/white-paper/3230/en/

  So if the function of the fan control only developed under an FPGA interface, I have to rewrite the control instrument part, seems to be a bit complicated...

  You can use the hybrid mode.

• NI 9401 pulse width measurement.

  Hello

  I'm not sure that I understand very well the pinout diagram. At the present time, I have a NI9401 in a NI 9172 chassis.

  DIO0 and DIO1 are connected at the gates of light. I have an opto switch and I want to measure the pulse width when an object blocks passes through the slot. Can I use one of the other free entry of the for do?

  The entries are DIO2, DIO4 and DIO5.

  The other IO pins are used as triggers.

  See you soon

  Hi Kamilan,

  If you explore in the measurement and Automation (MAX) and find your 9401, you can right click on the device and select "Pin of the device" which pulls up a window that says what features each pin on the device.  For example, according to this document, DIO2 is PFI2 to THE CTR0 CTR0 B and FREQ OUT.

  To answer your second question, do a right click on your device and create a new task for your 9401.  "You should do an acquisition of signals" counter input "pulse width and select CTR 1 on your device.  Once you do this, you can configure the parameters of your task and Max it will tell you where you need connect your signal source, which, for me, is DIO5.

  I would like to know how it works for you, thank you!

• With the help of a NO-9401 read the angular Position and trigger a reading I

  Hi all

  I am writing some software dependent vs angle chart and to the monitor when the buttons are pressed.  The software allows all DAQ lines to be configured so that multiple configurations data acquisition can be used.

  Currently, I peut use my NOR-9411 read the angular position of my quadurature encoder and trigger the playback of my entry (measured with a NEITHER-9219 or 9237) load on a rising edge of A or B input terminal analog.  Also, I can configure the software to do the same thing with a card OR-6259.

  My problem is that when I switch to a NO-9401 to read my meter task, I can no longer use the input terminals A or B to trigger my analog input.  I get error-200414 saying that the entry A (PFI0) is an invalid clock source.

  I know that the 9401 is configurable by nibble for input/output lines0:3 and 4:7, but how that affects the ability of a trigger, a route line PFI?

  Measurement and Automation Explorer shows it as an acceptable way of PFI0 AI/StartTrigger and AI/SampleClock.

  I joined the my code section that defines the tasks and that causes the error.  You take a look in the Utilities folder and open the Tasks.vi create.

  I am writing in LabVIEW 2011.

  Thanks for any advice,

• A measure of speed high speed with encoder in quadrature and NI 9401 on cDaq

  Greetings,

  We use an encoder in quadrature with 360 pulses/turn on the tracks (track A and B) and no trace of Z to measure motor speed at startup. Data acquisition, we use a NI 9401 in 9178 cDaq chassis and a pc with LabVIEW. The problem is that the start-up period is relatively short (less than 1 second), during which we measure speed as precisely as possible. The speed range is from 0 to 10000 RPM.

  What type of measurement method that you would recommend.

  Here are a few methods that we have already tried:

  -Measure with DAQmx CIFreq--> high frequency with 2 counters: speed measurement, but with a very big mistake (+ 166 RPM).

  -CIFreq DAQmx--> wide range with 2 counters: good speed data but more slow measurement,

  -CICntEdges DAQmx (counting separated the two lanes, speed conversion): very incoherent speed data.

  Thanks in advance for your help.

  I would definitely say a 4, the measure of a low freq called option with 1 meter.  (Frankly, I've never been

  fond of this name because it is useful for freqs much higher than what I expect most people think "low freq".)   This

  is the method that I almost * always * use for frequency of counter measures.  It works really well to capture transitional

  variations in speed.

  10000 rpm and 360 cycles/rev, you are looking at a maximum frequency of 60 kHz.  The frequency measurement mode 1 meter

  There will be 80 MHz internal clock by encoder cycle edges, then you will get more than 1000 strokes per measure.  The point

  that means only 1 number of quantization errors, you can expect<>

  Further, you can average overall, say, 10 samples to you give even better accuracy and you could still be a data capture

  rate significantly higher than the probable bandwidth of your mechanical system.  (The average would just clean the jitter and noise and would not

  Hide answer true mechanical characteristics).

• Digital output with NOR-9401 in cDAQ-9174

  Hello

  I have a cDAQ-9174 with an e/s digital NOR-9401 module. Now I want to output Digital signals on line0:3

  $line0: Boolean 1 time = 10ms

  Line1: Boolean variable 1 time = 20ms

  row2: Boolean variable 1 time = 30ms

  line 3:20 pulses (period = 250us, duty ratio = 0.5) after a time = 40ms

  the value of line0:3 must be Boolean 0 after 45ms

  Can someone let me know what I need to work to solve this please?

  Thank you all for your help.

  Thank you Christian for your quick replay.

  I have some experience in programming of microcontroller with C. I learned LABVIEW for about 1 month and followed a lot of demons in line and tutorials. I know that nodes DAQmx Data Acquisition screws and fundamental property.

  As I said at the beginning on the $line0, lin1and line2, they serve to control the relay in my circuit. 10ms could be controlled with the OS clock. Pulse of line3 series is used for IGBT gate signals, which is the critical moment. I want to use the clock machine to accurately control line 3 and synchronize at the same time the pulse with analog inputs from an another two NI9206 modules in the same cDAQ chassis.

  I just want to know more on the digital line demand signal relay output and a correlation between the line of analog input-synchronized finished pulse output. Waveform diagram is locked.

  Thank you.

• Two ports in the NI 9401 module?

  Hi all

  I'm relatively new toLabView, but I have to say that I'm enjoying learnicg it. My problem is that I need to generate two independent signals with a connected NI 9401 module a OR cDAQ-9172.

  I need to generate a sequence of bits to control a demultiplexer, the sequence is 0000, 0001, 0010, 0011... 1111, 0000, 0001... So far, with the help of this great forum, I managed to generate the sequence, my problem is that I need to use the other bits to control the spindle enable (bit) of an another demutiplexers cascading.

  I read that the NOR-9401 is configurable nibble, so I understand that I could use bits 0:3 to generate the sequence and 4:7 bits to control bits allow for demultiplexers. But until now I could haven´t this task, I see all the 8 rows as a single port and I was not able to learn how to configure two ports as outputs time and generate different signals.

  I'm using LabView 8.6

  Could someone help me please in this task, I would appreciate any help really.

  Kind regards

  Joseph

  Hi Joseph,.

  I thought after studying the best way to do it, not with the crazy arry.

  Use the power level 2 - n = 4 and x being the u8. You can then wire the output for the upper nibble DAQ.

  Note: If you have placed a number of u8 to a data acquisition task configured for the 0 line - it will seek only to bit 0. It is the extension of what ever and the number of selected lines.

  

  Hope this helps
