  Hello

  I'm trying to connect an instrument stahl ER-300 with labview. The Stahl is connected to my laptop via a serial port/USB converter.

  When I run the program, I get this error property node (arg 1) visa set up a Serial Port (Instr) .vi-> Untitled 1. VI

  the driver of the converter is set up and my phone is read as a COM4 and I Don t understand why I get this error.

  The program is attached.

  I need your help

  The error indicates that an input parameter is not valid to configure serial port VI... have you checked that you had wired up to this node correctly?

• Error: The property node (arg 1) in .vi VISA set up a Serial Port (Instr)

  Hello

  I've seen people once they have gotten this error, but none of them really apply to my situation.

  Right now I use LabVIEW example code to read from a device manufacturer. This device is connected using a Tripp Lite USB adapter series (http://www.tripplite.com/en/products/model.cfm?txtSeriesID=782&txtModelID=2430) for the connection from the PC to device with RS232. The adapter works fine when using the software prepared in advance (not LabVIEW) given by the manufacturer and the COM port is seen by LabVIEW. When I run the program, I get the property node (arg 1) visa set up a Serial Port (Instr) .vi (I've also attached the VI but it's a standard VI I got of LabVIEW). I get this error despite the fact that I use the same COM port, who has worked with the manufacturer's software.

  I have attached manual of Protocol RS232/debit BUS (not sure if this applies) that requires the device. The device is a mass flow controller whose operating instructions is: (http://nemu.web.psi.ch/doc/manuals/device_manuals/Bronkhorst/917023--Operation%20instructions%20digi...

  I'm using LabVIEW 10.0.1

  Any help is appreciated

  Try to restart the PC and then try the LV version before trying other software.

  I have seen thrid party serial interfaces work on the first try but fail when you switch to another application. It was as if the pilot did not know that it was no longer the first process.

• Time GPS, Position, Velocity.vi - error-1073807360 reading was held at node (arg 1) .vi property VISA set up a Serial Port (Instr)

  We receive information such as the Latitude and Longitude of a receiver Garmin GPS18xLVC via a serial port on our PC using LabView 7.1.  Successfully, I connected the GPS on the serial port and tested with HyperTerminal.  I tried reading GPS time, Position, Velocity.vi several times and still receive the following error message: error 1073807360 has occurred to the property node (arg 1) visa configure a Serial Port (Instr) .vi.  I think it has something to with the configuration of the VISA series under vi.  Any suggestions would be greatly appreciated.

  Thank you

  I understood the question, that I had with the time reading the GPS, the Position, the Velocity.vi.  The vi. "do not open" port com automatically and so I had to modify the NMEA GPS Subvi reading to first open the port (VISA open command) and then continue with other operations.  Once I did this it started to work very well.  I don't understand why this feature has been left out because it won't work without it.  I tested the code with a receiver Garmin 18xlvc and it seems to work fine.

• error of node (arg 1) .vi property VISA set up a Serial Port (Instr)

  Hi all

  I have a request, he had run on a machine well for months.  I use VISA to make the communication between PC and PIC.

  Suddenly at certain times, it reports error of node (arg 1) VISA property set up a Serial Port (Instr) .vi. Since then, it does not work.

  Œuvres of HyperTerminal.  I check MAX, the COM port it and looks very good.  What is the problem?

  Furthermore, I use VISA 4.2.  Maybe somehow it crashed?

  Many thanks for any help.

  Problem solved.

  The reason is that the hard disk was running out of space and there is error.  Somehow, causing accident DURATION VISA.

  We cleaned drive C: for free space and then repaired DURATION VISA.  Now, he runs with happiness.

  Thank you, everyone, for your help.

  

• Visa to configure the serial port

  I'm trying .vi VISA set up a Serial Port (Instr) allows you to configure my serial port.

• Can not read the serial port VISA without MAX

  Hello

  I'm trying to build an application that will interface with a Black Cat Systems GM-10 radiation detector.

  The app works fine on my computer (with the full development system OR) but when I install it on another computer, without LabView, the application cannot see the serial port!

  I checked that the driver is installed correctl and Windows can see the device, but when I run my program, he can't seem to access the serial ports.

  I then tried to install MAX on the second computer, how the application worked well, but as I install this app in other places, I don't really have the ability to install MAX everywhere (software must be autonomous).

  Any help would be appreciated!

  I would have joined the project file, but the forums seem to not want to allow me to download that big of a file.

  What version of LabVIEW are you using? With 8.x, the installer is very able to install the runtime of NI-VISA and MAX. If you are using an older version of LabVIEW, there is an option to include the series VISA support. Install just MAX will do nothing to make the available ports. This is the VISA that does this.

• The VI "VISA set up the Serial Port" will only work at 9600 baud

  I wrote a Serial Port RS232 RW.vi monitor of ' "which works for most. The problem is that it will not meet the alternative port configuration settings... For example: the default RS232 serial port configuration is:

  (COM1, 9600 baud, 8 data bits, 1 stop bit, no without parity)

  As a test, I use a Null Modem cable to connect to my LabView Com1 port to another PC running RealTerm Serial Port Monitor... Using my "RW.vi RS232' newly designed with the port settings of (COM1, 9600 baud, 8 data bits, 1 stop bit, no without parity), I can send and cannot receive data back throughout the day no problem...

  However, if I configure the port "RW.vi RS232" all other configurations, such as (COM1, 2400 baud, 7 data, 1 stop bit, odd parity bits)... He will not take the expected risks and continues to operate @ 9600 baud rate etc.

  Then, I changed the settings default "RS232 RW.vi" (2400,7,1, Odd)

  He still refuses to derogate (COM1, 9600,8,1, no...)

  I also went in the Device Manager of Win XP on the system of LabView and configured manually Com1 2400,7,1, Odd

  and yet,... work at the "RS232 RW.vi" @ 9600,8,1, none

  Everyone can test my VI in the car and see if they have the same problem of not being able to see the new changes in the Port configuration settings... other than (COM1, 9600,8,1, no...)...?

  FYI... Unfortunately my LabView runs on Version 6.0, you may need to up-conversion of the attached vi

  Instead of simply appreciate the comments, you need to implement.

  Having closed VISA inside the loop is definitely the problem.  And Crossrulz is 100% correct about the problem being that the serial port gets zero to default baud rate after the closure of the port.  Here's the proof.

  

  Note that while may have set the port settings manually in the Device Manager, these parameters are reviewed by the pilot VISA.  If you look in the measurement and Automation Explorer under devices and Interfaces > serial and Parallel, you'll see the default settings using the VISA driver.  If you change this setting, your program will work as desired.  But this is not the appropriate fix.  The correct solution is to get the VISA close out of the while loop.

  The port settings are established in this order.

  1. by Windows device drivers.

  2. by the VISA driver as set in MAX.  Since you are using VISA, these settings will be automatically replace #1.

  3. by the port settings, you set programmatically in your LabVIEW program.

• 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.

  

• How to periodically send various types of data via the Serial Port?

  Hello! Everyone

  I have to send data to LabVIEW to my device on the Serial Port.

  I know how to send data on serial port in LABVIEW, I already have this part.

  Now the problem is that I have several types of data I need to question my embedded device, if I want to send the query periodically command.

  So lets say that my four Op Codes are the following, which will send four different types of query command to my device on the serial port.

  (To be honest only OP_LED and OP_SENSOR is used now)

  0, OP_SYNC

  1, OP_LED

  2, OP_SENSOR

  3, OP_FUTURE

  Structure of basic package is as follows:

  Header (0x2C), Checksum, length of the data (n bytes), Op_Code (1 byte), length (length of Code + data Op)

  For OP_LED, I need to send the package as follows:

  0x2c 0x02 0x01 0 x 00 0x2F (0x2F being the XOR checksum) (calculation of Checksum part is done and SUB Vi form)

  Length of the package this is 0x02

  0x01 is Op Code for OP_LED

  In the same way

  For OP_SENSORi need to send the package as follows:

  0x2c 0x03 0x02 0x00 0 x 00 0x2D (0x2D being the XOR checksum) (calculation of Checksum part is done and SUB Vi form)

  0x03 is length of packet here

  0x02 is Op Code for OP_SENSOR

  So, how can I do this periodically in labview, in such sort that period can be adjusted whenever necessary.

  Is there something in LabVIEW to do.

  I had done the reception and decoding part and working properly.

  http://forums.NI.com/T5/LabVIEW/store-data-coming-from-serial-port-in-buffer-and-then-take/m-p/32722...

  So I must implement read and write the part of same while loop?

  Do not insert in the table if you put data in an array at index 0.  Just use array to build.

  No need to have Visa to write don't be a part of wire to the wire of reference and error VISA go in the upper part.  These wires should go THROUGH the entry VISA.

  Don't your checksum requires all the bytes up through data?  Righ now, you only put the checksum on data bytes and forget the opcode and length bytes.

  Your sending is not the opcode for Opsync or Opfuture.  You just send the empty tables.  At the same time for the other two, you put the opcode in the data table.  All your original opcode in the table build thread.  Get the data out of these structures in case item which is supposed to represent the opcode.

  xpress_embedo wrote:

  Now it works but I have now two problems.

  (1) OP_SYNC and OP_FUTURE do not data, but still receive its data on serial port, can I do something here as I have nothing when the table is empty in the structure of the case.

  I do not understand this statement.  Perhaps my answer above will fix any issue you have here.

  (2) how can selection operation Code to be send is done using control façade but real application, this task should be automated to a certain frequency, like OP_LED package must go out to the serial port to 100msec and packet OP_SENSOR must go out to 1000msec, I do this.

  Now you agree a little more architecture.  I would encapsulate the code that is in the while loop as a Subvi.  Then with the hand of your program while loop, use two time Express VI, a game for 100 msec, the other for 1000 msec.  When an express VI is true, run the Subvi with a command set waiting for the answer.  When the other VI Express is true, have it run the Subvi with the other set of commands.

  The device responds with anything when you send these commands?  You only send data.  I see no VISA Read to be able to recover all the data.

• Using the Serial Port for data acquisition Non-Serial

  I searched the forums and can't find anything on this topic.

  I saw that it was possible to use the parallel port for e/s digital single and I was hoping that the serial port can be configured the same. It seems all VI VISA only to use the serial port to receive ASCII characters at a given flow rate, but is it possible to simply query the status of the line series at my own speed to see if it is high or low, kind of like a single pin DAQ?

  It seems that it would be possible until the serial data are read and controlled by labview, not Windows. Let me know if you have ideas of how to approach this problem, or any comment as to why it is not possible.

  Thank you all!

  Select the property > settings series > Modem of the line parameters. For example, the State of the CTS is an entry to the pc.

  With the help of these lines is a very poor substitute for a scope or map DAQ. The only things you can return is Asserted, Unknown or Unasserted. The range of acceptable signals is important enough. Anything between + 3 and -3 is an unknown state. Your other signals is + / 3 to 15 volts. What type of signals do you really want to capture?

  Edit: there is no such thing as a visa so I have no idea of what you actually use.

• How to connect Agilent 8163 b via the serial port

  I have a problem connecting to the serial port with Agilent 8163 b. The driver that I use is driver_vxipnp_816x_4_1_4.exe. The problem always message display "Visa resource not found. Check the HPIB-Bus address"when I use the components inside the"hp816x tree.vi ". However, I have no error if I use normal read and write VISA.

  Y does it can someone help me answer my question? Thanks in advance.

  Thanks for the reply.

  I face a problem that you use with GPIB-USB-HS due to the physical dimension, as shown. The width between the remote locking connector (FIR) and (w1) GPIB connector to the appliance is too small for the GPIB-USB-HS (w2) connect to this topic. If I unplug the connector RIL, tunable Laser will not be activated. So I have a few questions as follows.

  1. the LabView can always activate the tunable Laser if I unplug the connector at RISK in my case via GPIB?

  2. the LabView is compatible with GPIB connector (model x 10833) Agilent?

  3. is there a way to solve the problem posed by the RIL connector unplugged?

  The drop box

  P/S: version please is 4.84 to 8163 b.

  Thanks for the help and I'm too new in this field.

• whille prob get bytes to the serial port for serial communication

  Hi all

  I have one using the series write vi to send the command to the instrument. the answer I get is read NICU playback vi. I use between read and write the serial port bytes accumulate bytes. BU what I observed is quite strange. When I run the vi with the debugger, I could c the bytes to port series is 201 and what I get in buffer is only 133.

  any1 can guess at what the problem would be b?...

  You don't show the function of VISA set up a Serial Port, but I guess you have the active stop character. Playback will end automatically when the character is detected and you should never allow when you try to read hex.

• 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?

• How to set the number of packages to be send per second on the serial port in labview

  Hello.

  I need to send data to the serial port such that each data packet must be sent at a rate of 4 packets per second? How can it be done?

  Thanks and greetings

  What defines a package?

  You just need to have a while loop with a timer waiting for 250 milliseconds surrounding your VISA writing the function.
