• Difficulty communicating with a GPIB instrument using VISA

  Hi all

  I am trying to create a Subvi allowing communication between a computer and a spectrometer to MS260i. This is an old spectrometer and can only be interfaced via GPIB or RS232. I chose to use a GPIB-USB-HS adapter to connect it to the computer. The following parameters in the NOT-MAX I would easily send commands to the spectrometer when you use the Communicator of NOR-488. 2. I have also attached a picture of a wavelength successfully query.

  

  

  However, I am unable to do a Subvi with the same settings. For example, the following VI

  

  Returns the following error

  

  Is there something that I forget? I also noticed that even if I saved the GPIB interface properties, these do come up not by default when you use the Communicator of NOR-488. 2. Indeed, I have to manually configure EOS settings every time that I reopen it tool.

  Any help would be greatly appreciated.

  Did you do a right-click on the control of the chain and select ' \'Codes display? If you do not, the stop character is not sent.

• Problem with 2 GPIB instruments

  Hello everyone,

  I work in a program with LabView 2015 this control 2 instruments, the Rohde & Schwarz Smiq02b signal generator and Analyzer of spectrum n9010a Agilent EXA. I use the cable Agilent - 82357 B USB/GPIB to connect my laptop with these two instruments (PC-> EXA-> Doganovic). I also installed the two drivers of instruments from their official websites.

  The program worked correctly until I had to format my computer and reinstall LabView but something wrong now.

  The problem comes when I run the program, is unable to initialize the SMIQ02b, the program stops and opens a new window of block diagram. This block diagram belongs to a block driver the instruments within this scheme, there is a VISA write flashing block.

  

  This only happens when I'm initializing two instruments in the same program, if I create a new VI and use the Doganovic only, I have no problem.

  I don't know what is happening, it is very strange that it worked well before, and now this happens.

  That's what I installed in my laptop:

  -2015 LabView
  -NI Device Drivers (included NI-VISA 14.0 and NOR-488. 2 14.0)

  -Agilent IO libraries Suite (configured as secondary VISA) 17.1

  -Passport OR VISA for tulip IT

  I'll be very grateful if someone could help me with this.

  Thank you!

  You set a breakpoint, it's what's causing the break.

• 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.

• Read several GPIB instruments

  Hello

  I have a question of time, when I want to read the GPIB instruments at the same time (1 to 24 instruments with 2 cards GPIB - GPIB0 and GPIB1).  The user can choose the number of instruments that it will read.

  For 17 instruments chosen for example, is an array of 17 lines connected to a loop where playback GPIB is made (see TestVi and Loop.jpeg). It took about 5 seconds to get all the data.

  But if I just copy 17 times playback (configured as a falling) Vi in a simple vi as in Untitled2.vi, tool around 1.5 sec to get all the data for the same conifguration! (See without for loop.jpeg)

  How could I read as fast as in the 2 without title vi with a for loop or something else in order to allow users to set more or less instruments without copying playback Vi once the configuration has changed?

  I tried to use call a VI dynamically , but it did not work.

  Thank you for your help

• 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?

• Problem with PCI-GPIB card control Agilent 8648 D generator interface

  Hello

  I downloaded the driver Plug-and-Play (project-style) for Agilent 8648 A generator of signals. I use LabVIEW 2011.

  I open the file project and resource VISA name menu, select COM1. Note that I use 82350B of the PCI-GPIB Interface Card.

  I run the project, and I get timeout error.

  Is there a problem in the PCI-GPIB interface or am I missing something? I'm new to LabView and PCI-GPIB interface, and I'd appreciate any help.

  Thank you

  Given that you do not use a NI GPIB, go to MAX, select software and NI-VISA. In the right window, click the Options of VISA, and then select passports under general settings. Check on the passport of NI-VISA for Tulip.

  I'm assumimg you loaded the driver of Agilent and tested the communication with their software.

• How to avoid the automatic launch of SignalExpress with a USB instrument?

  When I plug in (or activate) a USB instrument (I have 2 USB power sensors and a signal RF N9310A Agilent generator) - SignalExpress 2009 will launch automatically.  It is very annoying (and apparently by default) behavior.  With 3 switched instruments, I get 3 instances of SignalExpress which must be closed.  Anyone know how to disable this feature?  Of course, I'm sure I could just uninstall SignalExpress altogether, but not this option, what is the solution?  I'm running on Windows 7, with LV 2009 Professional.

  After some research, I found the solution.  As I said in the original post, it's Windows 7, so this may be a problem of Windows 7-specific.

  To disable the autorun of SignalExpress property when you plug a USB T & M class in Windows 7:

  1 run the configuration utility AutoPlay from the Windows Control Panel (Panel of-> hardware) and sound-> AutoPlay, or simply type AutoPlay in Windows Startup box.

  2. scroll to the bottom of the list and you will see-> Test and measurement device. Change the selection to "Control Instrument using LabVIEW SignalExpress" to "not act."

  3. Save and you're done.

  I suggest you this info. added using SignalExpress for the next version.

• 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

• 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.
