• Cannot add serial port in MAX

  Hello

  I have a cRIO 9076 and you want to use the port series. I can see the cRIO able and Automation Explorer, but I'm unable to add a serial port. I get the error "Internal Error Max could not get interface to database of the MAX". A new installation does not solve the problem. Any ideas what could be the cause?

  Thanks in advance

  

  Thanks for your answers, even if they did not help. Already tried to resolve this question of the repair of a corrupted Max database before posting here, but he has not changed a thing. An other error message told me that maybe NI-VISA has not been installed on the controller, so I installed just that. What I didn't know, is that you will also install "server of NI-VISA. Could be obvious to more experienced LABView users but I'm new to this software and the large number of software components is a bit frustrating...

  Anyway, problem solved :-D

• Add serial port to VM, get BSOD 0x0000007b

  The operating system is Windows XP and it has been converted from a physical PC about 2 months ago.  He was the starter and working for all of the two months.

  But this computer starts.  I have a snapshot that I can surely return.  And this snapshot successfully starts and restarts.

  But when I add a single serial port (which is a physical port mapping) you get a BSOD on startup.

  After getting the BSOD, if I remove the newly added serial port, he continues to get the BSOD... safe mode or not.

  I am able to join the 'hard drive' to another 'computer' and read / copy files.

  No minidump file is generated by the BSOD.

  I read through all the STOP 0x0000007B VMWare community articles.  While I'm sure it's related to that those who are all about the SCSI drivers and boot devices.

  He is a serial port...

  Someone at - it a theory or something to try?

  OK, so far, I've saved a copy of the VMX for bootable and BSOD.

  A diff seems to indicate that SCSI is get added.  I will try to reduce the VMX BSOD and see what happens.  I might be able to save myself, but feel free to drop some knowledge on me if you have one.

  As well as it did.

  I have nuked two SCSI lines out of the VMX file and it starts.

  scsi0. Present = 'TRUE '.

  scsi0.pciSlotNumber = "16".

  Don't know why VMWare 9 added THAT SCSI on a computer virtual set to IDE... perhaps that will happen every time I have to change the settings.

  Don't know...

  This virtual machine was a horrible time, conversion from physical to virtual and it never worked when trying to make the recommended patches SCSI community.

  Maybe when life slows down I'll clone and try to convert them into SCSI again.

• Need help to add serial port to a virtual with "Output to the file" computer in PowerCLI

  I have a requirement where I have to add a serial port to a virtual computer that is an Ubuntu operating system and the port type must be 'output to the file"with a file name specified in a data store on the same ESX host.

  Can anyone provide me with a script of powerCLI for this please?

  Thank you very much

  Suparna

  I advise you to upgrade to 4.1 PowerCLI.

  If this is not possible use the attached script that works for versions pre-version 4.1 PowerCLI.

  Hi David,

  The error is because you don't have to specify the 'fileOperation' in the VirtualDeviceConfigSpec to add serial ports. The virtual machine correctly, reconfigure if you remove the following line:

  > fileOperation = > $fileOp,

  In addition, properties "pipeName" and "end point" of "VirtualSerialPortPipeBackingInfo" are strings. Thus, instead of

  > my $endPoint = VirtualSerialPortEndPoint-> new ('server');

  > my $vdpName = VirtualDevicePipeBackingInfo-> new (pipeName = > $pipeName);

  You simply do:

  > my $endPoint = "server."

  > my $vdpName = $pipeName;

  Hope the above helps you to resolve the error.

• Add data from serial Port in the indicator series front panel?

  Hello! Everyone,
  I'm new to LabVIEW but has prior programming experience.

  I have to develop a front for my camera and this is why I need LabVIEW, data comes from serial Port, so I started internet research / LabVIEW forums and found various tutorials by the help I am able to do the part Serial Communication, but has got stuck in one thing.

  Whenever data from serial Port, it gets displayed on the indicator chain but clears quickly, but I want some data comes it does not erase the old data and new data to add with the old data.

  I read the string concatenation will work in this case, but I am not able to use it.

  Please take a look at my VI attached to this mail.

  You must use a shift register to keep your story.

  

  I recommend you go to some of the tutorials available.  They will help you a lot to get off on a lot of things like that.

• Add card serial port of the Optiplex 780 desktop

  I have a refurbished Dell Optiplex 780 compact desktop computer.  I would like to add an inexpensive PCI card that has two serial ports RS-232 legacy.  The description says that it is a "PCI to serial port card".  He mentions "for 5V PCI slot only."

  I think the 780 will take this card, but I'm not well versed on the specifics of the new PCI standards.  This card will probably work?

  Thank you

  Jan

  Typical PCI cards have one or two notches, according to voltage signalling. Cards requiring 3.3 volts have a notch 56,21 mm from the rear of the card; those requiring 5 volts have a notch 104,47 mm of the rear plate.  Universal PCI cards have two notches to allow them to be plugged into two system 5 v or 3.3 volt slots.

  According to the Manual, the 780 has PCI 2.3.  PCI 2.3 supports 5 volt cards. Your slot machines are probably universal whereas they should accept a card with the notches or both. But be sure that

  An important point is that the map you saw is low profile and full height. The manual said that 780 office accept "without editing card - up to two low profile cards. If you need to pay attention to the voltage more than just.

  And the desktop version does not have a PCI-e x 1 slot, which means you need to find a PCI card.

  Another alternative could be a USB > serial adapter cable.

• Option named pipe to add the missing Serial Port to Linux host

  Hi all

  I try to add a serial port as a channel named for a kernel debugging

  the installer, but this option is missing (see screenshot1). There are

  However the options to add the serial port in the file/socket.

  The host is 64-bit Fedora 10 2.6.27.24 - 170.2.68.fc10.x86_64 running.

  Workstation is 6.5.2 build-156735. I found that the named pipe option is missing, regardless of the type of the guest OS.

  I had posted this last week.

  http://communities.VMware.com/message/1267552

  and he said since as soon as I put in the following options in the marked .vmx file, a serial port option came (see screenshot2).

  Serial0.present = 'TRUE '.

  Serial0.filetype = 'pipe '.

  Serial0.filename = "/ tmp/com_1".

  I realized that I have a VM as the serial port server and others as a customer. So adding the option-

  Serial0.pipe.endpoint = 'server '.

  However, this option is breaking the vm configs (cannot start VM until I have delete this line).

  Please see the attached screenshot3 6.5.2 on Windows and you will see that there is a different and complete serial port setting to the research. You can easily set a virtual machine as a client/server side of the connection series on Windows.

  I would really appreciate if someone could give me some pointers as to why this difference between Linux and Windows, and how to get the type parameters for the serial ports under Linux Windows?

  My main goal for the purchase of workstation was to do kernel debugging using the serial ports, and now I'm totally paralyzed because of this. Pointers and suggestions are greatly welcome.

  Thank you very much

• Two module I/O servers. a serial port

  is this possible? It makes sense that you would wan't to put multiple devices on the same network series, so you do not have add extra ports to control you. I can't find the answer. I ould think that the API manages the port behind the scenes sharing, but who knows. Can I save myself a job and use the I/O Server, or I'll have to do this the old-fashioned way and use the modbus library?

  As long as you use a 485 port, you should be able to communicate with multiple devices using the Modbus over series.  It seems a little strange because you must have a different I/O Server for each slave device, but you can assign all use the same serial port.

• Measurement & Automation explore (MAX) cannot find any serial ports

  Hello

  I tried half of the internet, but I can't find a solution for my problem. Maybe someone of you have an idea :-)

  My System Information:

  OS: Windows 7 (64-bit)

  LabView: LabView Professional Development System 2015 (32 bit)

  MAX: Version 15.0.0f0

  NI-VISA: 15.0

  NOR-Serial 14.0

  I've attached a screenshot of MAX at the end of my post.

  All the drivers for serial ports are properly installed (see another screenshot). But Max, I can't find these ports. There is only the error code "0xBFFF0011 (VI_ERROR_RSRC_NFOUND). If I want to add the COM Port via 'Devices and Interfaces'--> 'New'--> ' Port (serial or parallel) ", I can only choose between COM1-COM4 and LPT1-LPT4. But I need COM9!

  Anyone have any idea what I did wrong?

  Thank you

  deZeus

  I looks like something is wrong with your installation OR VISA (as MAX does not find ALL ports).  Make sure that NEITHER VISA is activated (sometimes of other kinds of visa in the way), or try reinstalling NI VISA.  Serial number NOR is not necessary since you are not serial ports using OR.

• Store data from the Serial Port in the buffer and then take action?

  Hello! Everyone,

  I'm new to LabVIEW and I take assistance from various videos and stuffs available online to get started with LabVIEW.

  But I have a duty, therefore needing help.

  initially I see some of the tutorial videos and learned about the LabVIEW interface, and does a little project to communicate with the Port series (receiving and sending data).

  Happens to my task.

  My LabVIEW application will send a few State request packets on my device or control and based on the response packet that I have to display values.

  The Structure of package is as

  Header, length, Op_Code, data Checksum

  There is no terminator as newline or carriage return or anything else.

  In C language, I read the data from the Serial Port, and based on the length, I conclude that I got the full package or not, and then by recalculating the checksum value, the integrity of the package is verified and then based on that Op-Code has been sent will be decided.

  (I'm dealing with hexadecimal data)

  But how can I do this in LabVIEW.
  A tutorial or any referece will be useful for me.

  1. I suggest that you learn to use Shift Registers instead of local and global variables.  They are much more efficient (memory and execution speed) and make it much easier to read the schema.

  2. you don't need this inside the loop property node.  Is there a way to configure a Serial Port to turn off the stop character.

  3. you don't need to wait for playback VISA will limit the rate of loop if no data is coming.

  4. Once you have the length, you simply read the rest of the entire message and process it at a time.  This will make things a LOT faster.

  5. you should really do this enum a def type so that you can ensure that all your enum constants have the same values.  If you need to add a State later, simply update your enum in the same place then.

  

• Visa OR written closing serial port

  Hi all

  Currently in collaboration with LV2011 and NOR visa 2014.  In my application, I have 7 open including 4 serial ports I write for devices, 3 are simply listening.  Now, I write to 4 of these devices, alternating between them, the second time I try to write to a device, the writing is not received, but when I exit the application and close the port, the message is received. I saw this on 2 similar devices and it is a bit random. Possible, it is a matter of the unit, but I don't see this problem when you use the tera term.  We never seen it before?

  I can post code, but it is a great application and I use the AMC add on.

  Thank you

  Matt

  Using native serial or USB-to-serial adapters ports?  USB adapters often behave in certain circumstances wrong with LabVIEW.

  If he can be a bit of work around the problem, is it possible you can close the reference in LabVIEW just after writing of visa for 'forcing' the message, and then open again the serial port reference?

• Serial port doesn't work is not on the installed machine

  Hi people.

  I developed a labview program that reads from the serial port. It works fine on my development machine, but when I install it on a different machine, it will not work. I tried several facilities. Both the automatically selected installallers and checking the DURATION of NI-VISA 15.0. I also see shared components VISA 5.6.0 (64-bit) in installed programs. Do I need to add additional drivers or anything like that.

  I would assume that selected installers automatically chooses everything. I am blind as to what is the problem.

  Select this option.

  
  

• Agreement between MAX and Windows serial port.

  I use a laptop running Windows XP and LabView 8.5.  I have a variety of USB to serial port devices that I use from time to time.  In the past (from what I remember), has accepted the name assigned by Windows, and MAX (COM1, COM2, etc.).  Recently however, MAX seems to think there are three serial ports on the computer, but the tags with a little black 'x' by saying that the device is in a State of 'unknown '.  Using the Windows Control Panel, I see that no serial port is listed in the system until I have Plug one of the converters in.  When the converter is connected Windows automatically recognizes and says it works normally.  It seems that MAX does not allow me to delete the serial ports that scored because they did not add statically.

  Is there a way to clear the MAX?  This has not caused any problem I was not able to get around yet, but it should be clarified.

  Thank you.

  
  

• How to transfer files from PC to PC via a serial port using labview

  I need to transfer files (.txt, .doc, .xls) from PC to PC via a serial port using LabVIEW. Is it possible to transfer files, if so how to transfer?

  Yes, it is possible to transfer files with the serial port using LabVIEW.  The files are just collections of bytes and the serial port is good enough in the expedition of the bytes from one PC to another.  You must connect the ports series with a null modem cable.

  First, take a look at the example of serial communication.   In LabVIEW, go to the Help menu and select «Find examples...» ».  From there, you can search for "serial" or navigate to hardware input and output > series.  Select «Write series base» and Read.vi  Try this example to gain confidence on the serial communication methods.

  Then it's time to learn how to read and write files.  For this, the examples might be somewhat confusing as they deal with files that are presumed to have data of a specific type in them.  I would recommend just familiarize yourself with the functions in the file e/s palette.  Specifically, familiarize yourself with the following functions.

  1. Open/create/replace file - on the side of your destination, you will need to create the copy of the file you are trying to transfer
  2. Close the file - when you're done reading or writing to a file, you must close it.  It cleans the memory used and finalizes write operations that are still floating in the write buffer.
  3. Read a binary file - is the best way to play a file when you don't really like what type of file it.  In your case, you just want to get these read bytes and sent so they can be written down instead of destination.
  4. Write to a binary file - next to the destination, is what will store the bytes in the file that you created with the number 1.
  5. Size of the file get (under the range of the advanced features of file) - you need to know how big the file is, so you know when you are finished.

  OK, so once you are able to create files byte write and read bytes from existing files, you can move forward.

  I suggest the basic method is to have the user specify a source file on the source PC, and a folder on the destination computer.  Then find the size of the source file using the number 5.  Divide this number of size by the number of bytes that you want to transfer to the times.  The series pads are usually around 32 k (if I remember correctly) in order not to exceed that.  Now start to send data by reading a number of bytes and this string output wiring to the feature of writing VISAS.  On the side of destination, you will want to monitor the serial port for bytes and read when they arrive.  This string of yarn to the writing of the function of binary file to add them to your destination file.

  This is the basic outline of how to do it.  He needs to not to overload him write and read buffers on the serial ports.  Initially, you can use delays on the side sending to make sure that the side reading has enough time to digest.  To make things faster, you can bring in a control of flow.

  If all that sounds a little intimidating, there are there Alliance member companies (such as the automation of PrimeTest) who can write this code for you and even provides a turnkey for you solution.

  Happy wiring,
