CFP-2020-di-330

Hello world!

I am trying to make an acquisition of digital input using the CFP 2020-di-330, but I do not understand how to make the physical connections.

In the diagrams, I see two entries INa and INb, but I don't know who I have to use since I work with signals TTL.

I worked with DAQ, but it's a little different, I think that I have the external power supply to achieve... Thanks in advance!

TTL signal is applied between the INa and INb, reefer to the manual, especially page 9.

  • error of cFP-2020 by using entry to the worksheet File.vi

    System: cFP-2220 running LabVIEW 8.5

    We are using Scripture in the File.vi worksheet to record data to our PSC and get a very strange error.  It will not accept the name of the file and gives us and error that the file name is empty or a parent.  The name of the file is built as "YYYY-MM-FichierJournal.txt" and the actual value is "c:\2010-01_LogFile.txt".  Thus, it is not relative and the correct name is fed to the vi.  This vi is polymorphic and I use DBL 2D data.  I changed the text data, but it did not help.  In addition, I changed the name of file/path to "c:\1.txt" where it was a matter of length of file name. Nothing has worked.

    All the suggestions and help is greatly appreciated...

    Hi FilterGeek

    Your PSC-2020 and your cFP-2220 run a different operating system.  The cFP-2020 is to use Phar Lap and the cFP-2220 uses VxWorks.

    The two operating system use different path conventions.  Your specific question is explained here.

    Please let me know if you have any problems of implementation of the workaround that is listed in the article.

  • cFP-2020 market alone

    Hi all.

    I would like to know if I can run the cfp-2020 only with no backlplane and no modules. Just using the serial number and ethernet ports.

  • Unable to connect/configure PSC 2020 using MAX

    Hello world

    It's something like 'part II' to try to use the serial ports on our PSC 2020.

    I received a lot of help and valuable advice from Ravens Fan and others of the Spanish community in regards to the series, and I really appreciate their help.

    However, just at the point where I was about to make the first test, after you advise them, someone in my Department decided, there are a few days to clear (or format) all the contents of the memory of one of our CFP-2020. In addition, there is an another PSC 2020 which was unused for a long time. Well, the point is that none of the two controllers is seen by MAX, and therefore they cannot be configured by MAX either. Both are simply a blank space (i.e. nothing appears) under remote systems or devices and interfaces or another area in the configuration tree.

    Another important detail, we used an earlier version (4.xx, I guess) and also a newer version (7.x.x, I guess) of MAX trying to win again the communications. None of these versions could not communicate with one of the CFP-2020. In other words, none of these versions could establish communication or to show a sign of life of one of the two controllers. We test the wiring and it worked perfectly with the other PSC 2020 we have in existence.

    I guess that LabVIEW 7.1 or 8.0 (versions that we have) will not be able to communicate with controllers or if MAX has failed before. Am I right?

    Is there another way to see (contact) the CFP-2020?

    Is there a procedure for 'must - after setting shaped' that we are missing?

    This behavior has something to do with the DIP switches in the cFP2020?

    Is it possible to say if controllers are broken (fatal hardware failure) or if it's just a matter of software configuration?

    The deadline to begin a period of testing laboratory with the cfps 2020 is very narrow, and I really need to retrieve both controllers, so I would really appreciate help for this problem.

    Best regards

    I am pleased to have been able to help so far.  Let me see if I can help even more.

    First of all, to find a big stick and go fight anyone who formatted your controller overhead.

    Second, if you don't see anything under remote devices, I'll guess that the controller has been the installation of another IP address on a different subnet than where you are now.  I would try the instructions on page 3-6 of this Manual to reset the IP address.  That set it back on a 0.0.0.0 address who should make them findable by MAX again.

    Thirdly, MAX is up to version 4.6.2 (perhaps under minor version or two later.)  So, I'm not sure "newever version 7.x.x" unless you have a version number of LabVIEW.  Yes, you will certainly get the controller found in MAX before LV can work with it.  Definitely check the DIP switch as safe mode and reset the IP.  It is possible, that there is an incompatibility of drivers fieldpoint between the remote control and your LV version but I think that the two would have to endure somehow offset, otherwise you wouldn't be able to update the fieldpoint drivers in the controller.

    If there is a problem with the controller, I don't know how to determine that.  A person of OR may be able to help.  I think that the most likely scenario is that the last IP address defined for the controller corresponds to the setting for your PC or network, you are now, in which case the IP reset should help that.

  • While loop inside a timed loop

    Hello world!
    I use:
    -LV 7.1 + real-time;
    -compactFieldpoint;

    When I put some time, I noticed a strange behavior, loop inside a timed loop.  Let's fix loop timed with these settings:

    -Clock 1 kHz
    -1 ms period (Yes, I know it's short...)
    -offset 0 ms
    -Stage 0
    -Take the period of absence (ON) and maintain initial Phase (ON);
    -Timeout:-1.

    So, inside the loo, I put a traditional while loop, waiting (for example) an event will occur, and if this event doesn't happen, my cFP-2020 crashes! I mean, it becomes inaccessible for the debugger, and also, if I run a ping at his address, after a few cycles it becomes inaccessible as ping!

    Obviously, that statement of code lock the fieldPoint, because if I remove the inside while loop all work.

    I know that with 1ms duration, timed loop always the finishing of the delay, but I put the scrapping period missed and timeout-1.
      
    It seems to me that sometimes timed loop add overload heavi programs, I all so that the loop according to the tasks, even if my application has be in real-time!

    Tips welcome! Good day!

    Graziano

    Thank you very much for your answer!
    I'll test the entire application and then look for the best practice... but I still think I'll replace it timed with while loops loops...

    Good day!

  • lost the external monitor feature: NVIDIA GeForce GT 330 M video card needs to update the driver in El Capitan?

    Hello
    Apparently Apple no longer supports the NVIDIA GeForce GT 330 M 256 MB and did not update the driver in the operating system to account for its recent update Linux (below)? What is a macbook pro user to do? I know my MBPro is now 5 years - but with an i5 and 8 GB of RAM I think I shouldn't need to take immediately for new?
    Running any video seems to disrupt communication between my Vizio E240AR and MBPro - El Capitan OS (with NVIDIA GeForce GT 330 M 256 MB).  Power cycling the monitor and then force the MBP via a modification of the resolutions seems to temporarily improve the issue - until I have run video or insist on graphics card memory.

  • Pavilion 550 153na: R5 330 Max Graphics resolution

    What is the max resolutions 60 fps and 30 FPS available of 550 153 graphics edge r5 330?

    Is the HDMI 1.4 or 2.0?

    In my case, it will be used for video, but no games.

    Hi @Malc_Edwd, thanks for the reply.

    According to the characteristics of the graphics card, 4096 x 2160 is the maximum display resolution supported when you extend or replicate them to an external monitor or TV.

    It does not just playing games.

    I stand to be corrected the previous link I sent was for Mobile M330 graphics card, however you can refer to the link below for the graphic specifications R5 330.

    Link:http://hp.care/2dmU1RF

    Using the link that you may know well can run a game on your PC.

    Just mention details such as the type of CPU, memory and the name of the game it will tell you all the details.

    Let me know if it helps!

    Have a great day!

  • Qosmio F60 - 10J: black screen after XP Nvidia GT 330 M driver installation

    Hello

    On my Qosmio F60 10J, I installed windows XP on a DD of esata, I found almost all the XP drivers. XP works well, now...
    I downloaded GT 330 m XP drivers on the Nvidia site because the Web from Toshiba site, it's only for Windows 7.

    I installed these drivers XP of 330 m easily... but to reboot XP, after the XP logo, I have a black screen and a fan running at full speed.
    I tried to change the options in the bios, but it's always the same problem.

    You have an idea?

    Thanks in advance

    Hello

    Seems that the driver is not fully compatible.
    Try the www.omegadrivers.net graphics card driver
    But note; Drivers Toshiba not in use ONLY at your own risk.
    As far as I know, these 3 third-party drivers are not configured for mobile use and this means that the GPU could overheat and damage.

  • Support and driver updates on the Satellite P500-15F and Nvidia GT 330 M

    Hello all and thanks in advance for your help.

    First of all, I wonder if the toshiba support center works for all products... try again with 'satellite', P500 and you find not 15th!

    He continues with Toshiab Tempro... I can't validate my serial number...

    However, I wanted to update my Nvidia GT 330 M driver to the latest version 314.22 but can't fnd any info on the OEM driver...

    Best regards and good luck to everyone!

    >... try with 'satellite', then P500 and you will find no 15th!
    On this forum, you can find hundreds of threads with the same question and the same answer: to find your model, you must choose the short model number and not this part of the model name. THERE

    our P500 a short model number * PSPGSE * please visit Toshiba download page http://www.toshiba.eu/innovation/download_drivers_bios.jsp and check it once more.

    Latest drivers will be there. I have the model PSPG8E, original use Toshiba driver and don t have still no problem with video performance.
    You have a few problems with the performance?

    Satellite L500-xxx was equipped with an additional graphics chip (I guess that he s ATI GPU).
    Why you want to use the chart of your processor, if there is already another GPU?

    I m assuming that this integrated graphics chip HD would work only if no additional graphics chip would be available on the mobo
    Also, I found this notification on the page of Intel:

    + Intel® Graphics Technology offers you an experience visually optimized for Blu - ray * and HD video with Windows Vista * support¹ and comes standard with many laptops, mothers and desktop cards * without needing to add an external and costly graphics card * +.

  • Can you connect a cable DB37 to block cfp-cb-1 connector?

    Hi all

    I am looking at upgrading an existing unit of the point compact field to a unit of the cDAQ and I find a way to test the new system without having to release and rewire any old compact field point of terminal blocks to test.  I would like to connect the cable on the blocks db37 cfp-cb-1 connector that are on the existing system, so I can do tests with the new cDAQ replacement system without any wireless.  Unfortunately, the material is in another State, and I do not have a physical cfp-cb-1 Terminal block sitting in front of me to test to make sure that a db-37 cable mate correctly without running into the cfp-cb-1 module case.  Someone has he done this before, or know if a cable will connect without interference problems?  Thank you!

    All,

    I was able to put the hand on a block PSC-cb-01 and a fellow cable standard db37 male to this block of connection without any interference.  This can be useful information for someone in the future trying to update an old unit of PSC.  You can connect the test cables to the old PSC-cb-01 terminals to test your new system and easily return to the old system without having to release all the your existing connections to the unit of the PSC.

  • LV2010 and cFP-2120 and remote control panel

  • Variables shared on the CFP becomes zero and communicate with the PSC

    I use a PC with two network cards, one on one wired ethernet, the other on a private IP directly connected to a PSC-2120 (running 6.0.5 full). I use variables shared on the CFP and aliasing to static variable on the PC (initially LV 8.6, now 2009f2 with the same problem in both). PC variables are stored in a database of the Citadel. I have the CFP program built to run at startup, and it works fine when not connected to the PC.

    When connected to the computer all variables shared on the CFP will from time to time (almost 1/min for a few seconds) and randomly becomes zero. Even if they are resized only not to allow to become zero. I can say that what is happening because I use the variables shared as relay alarm thresholds module, and relays to suddenly slam on. I confirmed this by checking that the CFP has written to its internal flash memory card, and indeed variables suddenly are nil. On the PC it says that it cannot connect with the shared variables. This happens although LabView is not running on the PC!  Manager distributed system variables shared on the CFP are listed as (disconnected) during this time, but it continues to be able to read the correct values to live of the CFP entered the module.

    Interestingly, I have the same computer with the same configuration (and a PSC-2120 different) that does not have this problem. Both PC's are new from the factory. I tried to disable the second ethernet adapter, closing all wall-lights/virusscan and re - order network cards in windows networking/advanced settings without success. Simply disconnect the cable between the PCP and the PC does not cause this problem and shared variables become zero does not trigger the network on the CFP monitoring parameters.

    My questions are:

    (1) this problem can be fixed?

    (2) lost communication for a few seconds is OK, but given the PSC variables become zero is not. Can I stop the variables of the PSC to become zero?

    -David

    To update my previous post, it turns out that the re-installation was not the solution (the problem of variables start again occurring began). I finally realized that this only happens when I put the CFP time server IP (under Additional Configuration to the MAX). I was upgrading the server time on 192.168.1.1 IP (the IP address of the adapter of the CFP has been directly connected to). However, this compensation setting solves the problem.

    I do not think that the time on the CFP must need to be addressed too often (and perhaps it is synchronized if I never re - deploy files to the CFP?), so I guess that leave it empty. Curiously, I have the same setup time on an another PSC server IP and PC (running LV 8.6) without problem.
