• USB-6525

  Hello

  At first, I want to control a USB-6525 in labview. I want to creat 3 switch control relay as if switch1 is out of relay 1 is open, switch2 is narrow so relay is close

  Can I control switch using the DAQ (Labview8.5) Wizard, I choose relay wich I want to open/close, but I don't know how to connect with a switch for failing to enter the DAQ assistant.

  Secondly, I would like to control them by timers but I first want to understand how it works with the simple switch

  Thank you

  Kind regards

  PS: I'm french so sorry for typos

  Please answer me

  I'll try that

• USB 6525 6501 digital for output to the step motor

  Hello

  I try to use USB 6501 or USB-6525 out of step motor signals which command the stepper motor. My questions are

  (1) do I 6525 USB, I'm not sure the function of it (perhaps as a relay).

  (2) now I connected input 5V for USB-6501 "+ 5V" pin and GND to pin "GND". On the other side (output side), I connected ' enable '(from motor drive) to P0.0. 'direction' to P0.1 and GND to GND.  Can I use the express signal to test, the error says "lack of entry."

  (3) I guess the next step is programming labview. Does anyone know of similar examples?

  Any help would be appreciated!

  Melody,

  If the engine must input external logic level I advise to use the USB-6501, which is just a digital I/o card. The USB-6525 housing does not have the digital outputs to control your motor drive. If I understand correctly you just try to turn the motor on and off with a digital signal. It seems that you also provide your drive motor + 5 v and GND. The USB-6501 has channels for + 5V and GND. I've attached an example of navigation that controls the outputs digital using DAQmx and LabVIEW. This specific programme allows to control 8 digital output lines, but it looks like you don't have one. If the engine waiting for you just a strong to put logic in operation and a logic low to shut down this program example will be able to turn on or turn off your engine. Just connect one of the USB-6501 digital output lines and then use the program to this line of control.

  I don't really know any reason, you need to use the USB-6525 it seems to me that the USB-6501 run action you need. I hope this helps.

• control solenoids with USB-6525

  Hi, I'm new to Labview and try to use a USB-6525 control six independent valves.  They'll be turning on and off at different frequencies to control a cell infusion system.  I drew a diagram that allows me to program schedules that the CRDD is closed and open.  The routine is inside a while loop to repeat until a given time has elapsed.  I can duplicate this six times to allow each valve must operate independently.  But I would like to trigger all tasks at the same time.  How do I synchronize loops so they all start at the same time?  Simply put all the loops inside a conditional loop, or it will run the tasks in the order?

  Thank you

• I can parallel two solid state relay ports for a maximum current of 1 AMP USB-6525?

  Hello

  I plan use USB-6525 to change a PSU 7VDC/1 AMP DC.

  USB-6525 having only 500 my maximum current for each channel, I can two parallel ports of relay to solid state for a maximum current of 1 AMP?

  Is it safe to use in this way?

  If not, is there any other USB device can provide 1 channel AMP relay?

  Thank you

  Hi Ben,

  Yes you can do this, please refer to the KB, it contains the information you need

  Can I use several relay on one device to allow power to pass?

• Turn it on and an Opto SWITCH with USB-6525

  The attached photo, a composition of a circuit consists of: Mitsubishi PLC FX series, USB-6525 and OPTO Switch (PNP OTBVP6). In the code, I put under tension of the OPTO then cutting the voltage; power on/off, using the USB-6525.

  My problem comes when that at some time in my code, the OPTOMETRISTS remain without electricity (immediately after programmatically, I just

  They shall ensure with outputs USB-6525 high level). I already checked the code, in my opinion its seems fine. I have in mind the 6525 isn't a fast DI / DO peripheral, that's why I use delays above 200ms.

  The last hope is to change the USB6525 for a brand new, it's what I'll do. But if anyone see a problem with the code or has another explanation why the OPTO not to receive or be (somehow) not powered, I'll really appreciate your help.

  I also enclose the .VI

  I really need help.

  Thanks to all in advance.

  I found what was going on. Connectios, common, everything was fine. In the code, between the States (I use a state machine structure) missed me a delay of 200ms. This because I change the outputs to reading entries, so between them missed me a delay, that's all. in any case, thanks for your help!

• USB-6525 NiDaqmx how to detect where the device interrupts the communication

  This could be considered a more generic question for NiDaqmx, but I write a custom control for internal use with the USB-6525 and possibly other devices of i/o using c#.  I use DigitalChangeDetectionEvent to warn me when an entry has changed and everything seems to work very well.  In an effort to be complete, I decided to unplug the USB cable and see the result and found that no error has been detected until I tried a writing output.  This is not acceptable because under normal conditions abstraction entry begins a process that will change output - given that admission never happens, the system is basically hung.

  I tried many things and have spent more time on what I want to admit so I would like to hear suggestions on how to address this problem.  Here are my attempts that I am not satisfied:

  (1) periodically switch (pulse) output that allows to detect the problem, but I may not be an available exit, so this isn't a good situation.

  (2) periodically trying to read the input byte with the same entry workflow, this does not work because I believe that the other player is still active with the DigitalChangeDetectionEvent.

  (3) attempted to take the message of Windows to change hardware, but seems too complex.

  (4) I read on the guard dog, but not sure that it is available on the box USB-6525.  So before I start with this I'd hear rather suggestions of others with more experience.

  Any suggestions please?

  THX, Ed

  Hi IntegroEd,

  Those are all very innovative way to potentially address the problem, and I'm sorry you haven't seen success with them.  Fortunately, the typical way to capture a break between a device of data acquisition and monitoring system is indeed a timer, and the 6525 has the innate ability to use the feature, as seen on page 5 of the user manual.  I suggest you go that route, if another user does not post a peripheral solution specific to your case.  This is a documentation on the implementation of the monitoring-

• LabVIEW.lib or labviewv.lib?

  Hello

  I'm writing a C++ DLL that interacts with the LabVIEW code, which uses features of LabVIEW Manager. The linked article says I should link against labviewc.lib, but there is another similar library called labview.lib

  What is the difference between them? Which should I use?

  It's labviewv.lib not labviewc.lib! Generally, you should use labviewv.lib for all new development. It handles better on the right the LabVIEW core binding when you have complex situations such as a DLL LabVIEW (screw of LabVIEW compiled into a DLL) that uses the DLL and when that LabVIEW DLL is called from a LabVIEW system which is a different version of which was used to create the DLL of LabVIEW. With labview.lib, this scenario is very likely create a chaos he is trying to link to the system LabVIEW calling instead of runtime DLL runs under.

• State of relay by default USB-6525

  Hello

  When the NI USB-6525 enclosure is powered on the default state to solid state relay is closed.  I'm trying to use it to control a 4 position RF switch.  Obviously we do not want to be on as this disrupts the 4 switch inputs.

  Is it possible to change the default state of the relay, so that when the device turns on the relay are all open rather than closed?

  Hi SeanJ,

  Sorry for the delay on this point - I just noticed this post by searching for clients who may have encountered this problem.

  From DAQmx 8.9, programmable start-up States have been added to the USB-6525.  However, flash on these cards was not initialized correctly to 'open' State, so the check for PPS caused tips have added a default PPS to 'closed '.  The solution is to simply set the States start to their desired state.  This can be done through MAX as follows:

  

  

  All the councils that are currently on the market have their flash correctly initialized to the open State.

  To reduce the risk of this question anyone adversely affecting during updates, we also add a check for the firmware in DAQmx 9.2.2 and later charger to initialize the flash if you are upgrading a version of the driver without PPS.  If the upgrade to a version of the driver with PPS, the startup States will not be affected.

  More information can be found here:

  I apologize for any inconvenience that you please do not hesitate to let us know if you have any questions.

• measure the State of the output to USB-6525

  Hi, is it possible to check the status of microsatellites in a USB-6525 using a multimeter.  I hooked up a meter to measure the resistance through the P0.0A and P0.0B output connections.  I wanted to use the automatic test routines to check the SSRs were closing.  As expected, there was an open circuit when LIFE expectancy was 0, but the circuit seemed not close when I changed the TTL of 1.  Do I need to connect to a power source and load to be able to see the closing SSRs?  Is not which is what a multimeter?

  Thank you, Nick

  Nick,

  Multimeter will not provide the source of tension and support you need.  Check out this link.  http://digital.NI.com/public.nsf/allkb/B0FF01B2AFFA52FC862573A2005A9570

• Watchdog USB 6525

  I need to return my USB-6525 to state results course in case there is a problem of communication software.

  Basically, I have sent close the relay for a short period s.5 a.25 seconds then the relay open. I can do this by writing a loop for close and then delay for the milliseconds and then open the 2nd iteration.  It works fine except the relay must the software or computer in bulk communication unit would remain shut down and cause a dangerous situation.

  The literature indicates you can do this by setting a watch dog timer but I can't find how to configure it. The way I understand, once the watchdog is set if it does not receive a software reset within the time limits, it will define the output for which is determined the safety position.

  Someone at - it an example of configuration of this device.  Either way, I would also do this with a SCXI-1163R also module.

  Another solution would be to send a pulse on a specific length of time, but I do not think that the 6525 allows execution of timed material.

  Thanks for your suggestions.

  Randall

  There are DAQmx watchdog timer screws if you have the driver installed DAQmx (installed device drivers), you can easily configure and use this timer. Their screws is very explicit.

• convert elements using the DAQCard-6024E card to USB-6221using LabVIEW 2009

  I just got an old project, the VI has been primarily designed using the DAQCard-6024E map. Since we would be upgrading the equipment and the DAQCard-6024E serves not long. However, they want to keep the similar façade. I am trying to convert the drop-down menu that I can use with USB-6221 with Windows 7, but I don't know how. Can anyone help?

  Windows 7, NI USB-6221, LabVIEW 2009 sp1

  Hi smoothenigne007,

  After watching your upgrade.  All your writing VI should use the same task.  There is no need to close this task until the end of the program.  In addition, you can remove all the time because they do not allow the task close a loop.  I did a performance highlighted with your code and you can see that the first task was not allowed at the time wherever the data reached the second task.  When you try to create the second task, the error is generated.  Because you do not give me multiple writes to the same port there is no need to open and close the task each time.  Here is a link that will explain a little more about the DAQmx driver works.

• How to convert the file with VI for LabView .lib to CVI?

  Hello

  I have the .lib file for my lock in the amplifier. The lib file is written for labView and already contains a visual interface (like ActiveX). The point is that I need this file for programming in CVI (8.5). How can I convert a LabView ICB .lib?

  Thank you.

  Denis.

  You said that you had a .lib file and in fact you have an llb file. There is a huge difference between an "i" (eye) and a 'l' (ell).

  There is a LabVIEW Instrument Driver Export Wizard but it's only for new pilots of project lifestyle and you need LabVIEW. There is no other way to convert a LabVIEW driver to a driver of the CVI. If the LabVIEW driver uses methods and properties of the ActiveX, you will need to write the same thing in CVI.
