• Problem with getting communication with old instrument GPIB-ENET/100

  Hello!

  I'm trying to get my program in VB.net to communicate with an older instrument (Infratek 305 A, measure of power) via a GPIB-ENET/100 device.

  The manual of the instrument does not say what GPIB standard, it supports, but the instrument is detected by the measurement and Automation Explorer.

  Detected by that I mean that MAE has detected an instrument located on the right GPIB address, but indicated identification is the output measure instrument string

  instead of the name of instrument (as shown for some more recent instruments of Agilent).

  When I run my application, I followed the communication with NISpy.

  Configuration of the device seems to work and I present only once in the program.

  The problem is reading data from the instrument. Whenever I read the data, I get a correct string of the instrument. But the problem is

  I get the same data in two consecutive and all readings first after that I get new data and also these new data are received in two consecutive readings.

  According to the manual of the instrument the instrument generates the data as follows:

  "A row of data ends with CRLF. The instrument can send multiple rows of data. "When all of the data transfer is complete the EOI (end or identify) is sent.

  My endpoint settings are:

  Send EOI to write complete: YES

  Terminate read on EOS: No.

  EOS byte: 2

  8 bit EOS compare: YES

  Define EOI with EOS on write: No.

  How can I configure the GPIB-ENET/100 to work with my instrument?

  Here are som NISpy logs:

  Hello!

  I don't have the opportunity to test with other controllers.

  However, I found a solution to my problem.

  The instrument should output 4 lines of data.

  L1 - line with comments

  L2 - line with current values

  L3 - line with the values of voltage

  L4 - line with power values

  The first line of the reading stops the instrument of implementation of additional measures.

  The measurements in the instrument began reading the last line of data (L4)

  The problem was that the instrument for a reason any also released a fifth line, which was empty.

  Read this line 5' th stopped the instrument again.

  By configuring the HW to finish reading on EOS, with EOS PMQS, the value byte, I could read the

  buffer of the instrument with a line output instead. This way I could read just L1 - L4

  and the instrument could work again.

  Next time I should read data from the Instr. first of all, I would like to read the empty line, then

  L1 - L4.

  Why the outputs Instr. an additional empty line will be left not resolved.

  My problem is solved.

• Implement the json JWT with labview web token

  I need to implement of JWT authentication with labview, how can it be done?

  I'm not aware of an existing library of JWT for LabVIEW. You can see the site of JWT to the creation and analysis of JWT requires:

  JSON encoder / decoder

  base64 encode / decode

  and a signature / encryption method (commonly built HMACSHA256 depends on the Oracle application)

  JSON encoding and decoding is available for LabVIEW 2013: https://zone.ni.com/reference/en-XX/help/371361K-01/glang/flat_unflat_string/

  The other two are not available of NEITHER, but have implementations in the LabVIEW community:

  Base64:

  https://decibel.NI.com/content/docs/doc-5544

  https://decibel.NI.com/content/docs/doc-23233

  Signature:

  https://lavag.org/files/file/198-encryption/

  If unfortunately JWT support is not provided by default, but all the necessary parts to the realization that he should be here.

  Hi gullo56,

  Welcome to Microsoft Answers Community Forums.

  To help you better I would ask,

  a. If it functioned very well under Windows 7 before?

  ·         I suggest you to disable your firewall security software and check if you are able to play the game.

  From the link below, what I discovered is Microsoft Flight Simulator 3 is not completely compatible with Windows 7, but I would suggest that you follow the steps below to help troubleshoot your problem.

  http://www.Microsoft.com/Windows/compatibility/Windows-7/en-us/search.aspx?type=software&s=combat%20flight%20simulator%203

  1. as Microsoft Combat Flight Simulator 3 is supported by Microsoft Windows Vista to function normally, I suggest you run this program in Vista compatibility mode in Microsoft Windows 7.

  For information about how to run a program in an earlier version of Windows, visit the link below,

  http://Windows.Microsoft.com/en-us/Windows7/make-older-programs-run-in-this-version-of-Windows

  2. you can also try to reduce the hardware acceleration and check if it solves your problem,

  1. Click Start-> Control Panel-> appearance and personalization.

  2. under customization, click on adjust the screen resolution.

  3. in the display settings dialog box, click the Advanced Settings button.

  4. in the monitor Properties dialog box, click the Troubleshooting tab.

  5. click on the change settings button.

  6. in the Security dialog box, click on continue.

  7 move the hardware acceleration slider to none to reduce or turn off video hardware acceleration.

  8. click on OK.

  9. restart Windows.

  Hope this information helped you.

• DASYLab is not communicating with the hardware dbk25a3

  Hello:

  I'm trying to troubleshoot a high pressure processing equipment. This system uses a PID controller. The level of pressure does not stop at the set point, but continue to increase. I am trying to solve this problem. As the program was written by someone else and there is no documentation on what each represent module and done. It is very difficult for me to solve the problems. Therefore, I decided to start all over again with my own module.  However, I have a problem. My hardware (DBK25 and others) is not communicating with the module of Dasylab. I tried several different things, that nothing seemed to work. I get this error.

  DBK25A3O

  An entry of a module is open.

  Any help is highly appreciated

  Thank you

  The error message indicates that you have a module that has one input open - nothing is connected. You must have a data wire to all entries.

• SPI Communication with PIC24HJ256GP210

  Hello

  I need make the SPI Communication with hardware PIC24HJ256GP210 in LabVIEW 2010 with NI USB 8451.I want to send 8 bytes data and receive data of 8 bytes of PIC. I'll send data byte-by-byte change the signal of the chip Select (CS). Before you send the data I will send ENQ (mark 3A) to check the status PIC, then after receiving ACK (Acknowledge as A1), I will send the data packet.

  My test procedure indicated below,

  • Setting clock polarity at zero (LOW idle), a second Edge clock Phase) and the clock frequency of 1 MHz to device NI USB-8451
  
  
  • 3 sending data (ENQ) and followed meaningless data byte by byte, also change state Chip Select
  
  
  • No explicit deadline has provided since the sending of the API takes 20msec to run
  
  
  • Receive the acknowledgment of receipt (A1) of the sensor
  
  
  • Send DataPacket [Eg: A5, 03, 02, 00, 00, A6, 2 c, DD] byte by byte, also changing chip select signal
  
  
  • No explicit delay gave between each byte from API takes 20msec to perform sending
  
  
  • Send 8 bytes , which means less data byte-by-byte, and receive byte-by-byte data PEAK
  
  
  • Received all of the data of 8 bytes with an incorrect value

  If please review my test procedure and give your comments if you have worked with SPI or if you have any input for my query.

  Thanks in advance.

  Note: Tie my code with this mail for your reference.

  Kind regards

  Nicolas.

  Hello O_Proulx,

  Thanks for your reply.

  Communication SPI after sending the data we send again meaningless bytes, which equals how many bytes we would like to receive the answer System.So we cannot read the data in the same VI as you mentioned in the code.

  My problem has been resolved. Byte meaningless, I need to send the file HEX .beacuse 'AB' has been developed in this way.

  Kind regards

• RS 232 communication with a projector

  Hello! I work in communication with my prjector. The controls are pretty simple, just PWR it for OFF\r PWR to turn off and LAMP? How many hours have the lamp worked \r to land the aircraft. So I just used the example of the writing/reading series with labview, but had a few problems.

  1º) it works but it keeps giving me an error, I can't handle. Is the current operation of visa wait time. I tried it here and all the people say something on the lines of commands, but I put them and set up in the port, so I don't really know how to handle this error. Another thing, it is how can I put \r or 0xD for my end of just the default write command?

  2º) how can I make my request just be an exe that you don't have to press ' EXECUTE ' always to use it?

  3º) my last question is to ask questions about how to manage this thing, I need to read used with the control LAMP lamp hours?, and projector will answer me with something like: LAMP = xxx. How to handle this response to send it via TCP/IP? Should I have to create a new variable or something? I mean, I just need with another application in order to power switch of the projector via tcp/ip and calling hours of lamps via TCP/IP, so I don't really know how to handle. Thanks for all the peoples and let me know if you need more information, I'm not native English sorry for my mistakes.

  Edit: I forgot to put my vi.

  1. you will obviously get a timeout when you send the commands that do not generate a frequency of the instrument. Only do a reading when you send the LAMP? interview and to automatically send \r, set the stop to "0 D" character.

  2. you have the app Builder to create an exe file. In order to make the VI automatically running, go to the properties of VI > execution and check "run then '.

  3. I do not understand. First, you talk about RS - 232 and now you want to convert this TCP/IP communication VI?

• Checking the status of communication with NI DAQmx or NI6143

  Hello world
   
  I'm working on checking the status of communication with NI DAQmx or NI6143 in Microsoft Visual Studio 6.0 C++ on Windows XP. The communication situation is checked between the DLL and the NOR-DAQmx/NI6143. I wonder what is the command for the control of communication for NI DAQmx or NI6143, and if there is no code available. Any suggestion or advice is greatly appreciated.

  Thanks in advance.

  There are many examples available on your computer that install with NI DAQmx. For examples in C/C++, follow the steps listed in this white paper:

  http://www.NI.com/white-paper/6999/en

  If you are new to data acquisition, that I suggest using LabVIEW. LabVIEW has several examples to begin to use a data acquisition equipment. To find them, open LabVIEW and select help > find examples... > Input and Output material > DAQmx.

  As a note of clarification, NI DAQmx is the driver used to communicate with your device (NI 6143). You do not communicate with OR-DAQmx itself, but use it to send commands and receive data from your device.

• Modbus communication with a piezoelectric dynamometer

  Hello..!

  I am a new user of LV and I try to communicate with a piezoelectric dynamometer in modbus RS232.

  After you install NI Modbus Library, I created a master VI with labview 8.6 using these libraries and I can get communication with scale, these values are added in the registry U32Bit 1 and it's good, if I press a load cell, I can see the values exceed. (from 0 to 65535). Now, I want to show on the front the weight in KG, as the decimal separator, for a proper interpretation of the value for my client, so I added a block table to unbundle that I convert a value with I32Bit (-32768 a 32768) with a flag, but I don't see not all values...

  I guess I did something wrong (conversion), I read a few KB, but I do not see a solution...

  Can someone give me a link or information to show me an example to convert this value... ?

  Thanks in advance for any help to...

  Configuration of master VI:

  Read now register

  Address starting 2012 (query to get the net value of the load cell)

  Quantity 1

  Slave address: 1

  RTU

  9600

  3 com

  parity none

  Can you post some examples of bytes you receive from the Modbus read and you expect that these values are?  It's probably just a matter of the right of casting, or the number endianism, or operation of scale that must be done.
