TCP/IP visa write stop character

Similar Questions

• Why do I get a warning "stop character has been read" with VISA read and TCPIP?

  I use VISA readings with raw sockets TCPIP without problem with NI-VISA 3.0.1 but when I moved to NI-VISA 4.4 I was getting timeout errors.   Time-out errors disappeared when I put the stop character allow the property (which seemed to be default in NI-VISA 3.0.1) but now I get a warning indicating that the "stop character was read.

  Can I turn off this warning?   Can I put the ending character activate by default?   How can I get rid of this annoying warning?

  Hey, Dagwood,.

  Unfortunately, there is not a way to globally change the attribute VI_ATTR_TERMCHAR_EN to VI_TRUE.  Talked with R & D ability to use registers and they say that it is not accessible through that.  To answer why this change was made so the developer who made the switch isn't around more I can not find his reasoning to explain.  The best to you in your code would be during initialization, use the node property VISA to make the change and until the closure of this VISA resource, this change will be the value that you assign the value.  I'm sorry, we cannot provide any other solution for these problems.  Also, if you feel that it is a heavy load on your programming practice you can certainly submit a product idea for the ability to change the overall values for default attributes VISA.

• Request stop when I write a character with a ^ as a i u e o... (French text)

  Configuration: MacOS 10.10.3, Adobe Story more (desktop app), French.

  Hello

  Since the last update of Adobe Air, Adobe Story more stops without any warning when I write a character like a, e, i, o or u (widely used in French!).

  Thus, it is very difficult to write a script

  There was no problem before this update.

  I deleted my preferences, but this was not a solution for now...

  Any ideas?

  Please, fix this bug soon!

  Thank you.

  Guillaume.

• Change the stop character doesn't seem to work

  Hello world

  I hope that this will be a quick fix and I'm just on something stupid!

  In short, I'm doing a LabView program to control a pump syringe via RS - 232. I use a Keyspan USB serial adapter to connect my laptop to the device. After a repair on my own, I was able to download a program HyperTerminal and can communicate with my well pump (change of position, speed, during initialization, etc.). However, when I try to do the same thing with LabView, nothing happens.

  First of all, I can say that LabView sends my pump data, because the light on the USB-serial adapter flashes quickly once (its indication that it comes to Rx/Tx). The same thing happens when I communicate with him via the HyperTerminal program. He seems to be in working condition.

  After a lot of reading posts on this forum and developer of the examples, I think that the problem is to send a character of endpoint with my data string. For example, when I have the program HyperTerminal open, I can enter "/ 1ZR ', which will initialize the pump. That move the pump to its original position and prepares for further information. When I go into the properties of "stop character" in this software, it is said: '13,10"(with the quotes). As far as I know, 13 in decimal is a return carriage (or 0xD hex) and 10 is a line break. I don't know if it sends them both. The company says that my program does not work because my LabView program is probably not send the right stop character.

  I tried almost everything I can think of to change the stop character. I know that the VISA VI set up the Serial Port uses the same settings as my COM port shows when I open Control Panel (9600 baud rate, etc.). I had a big bang and thought that maybe I should check MAX and see what his settings are... they are the same. HOWEVER, when I open the "VISA test Panel" on MAX for my COM port, under "Settings/o", the stop character is set to line feed \n. I have change to \r carriage return, but when I click on "apply changes", I get this:

  SET to 0xD stop character
  No error

  And when I close the Panel test and re - open, always back to \n line break. I also tried to change the setting of "tank of termination" in the VISA set a Serial Port to a constant (as a 13) or control (which I tried like 0xD hex as well as 13 decimal).

  I'm fairly convinced it's the issue... If anyone has any idea on how I can force it to use a carriage return? I even tried to disable 'enable the separation tank' and manually compose a string with a \r at the end, but it does not work either...

  I have attached a photo of a simple VI which shows what I want to do (the 2000ms waiting was put there just so that he would not close the COM port before initialization completed... its useless I think).

  Thanks for your help in advance!

  The stop character with the definition configuration function has absolutely nothing for adding a character of termination in writing. Look at the advanced example for how to do it. In addition, if you want to do with the string you enter, you must activate '-' code display. It is a right click option.

• stop character during the IV sweep with keithley 2600

  Hello.

  I have a labview code to make the IV scans on a solar cell.

  When I sweep V and I measure, it works great every time. Totally reproducible results.

  When I I sweep and measure V, I get randomly 410 interrupts with the vi printbuffer() when playing back the results.

  On the edge of survey error, I find the following details of the error.

  WARNING 1073676293 was held at VISA read in KE26XX.lvlibrint Buffer.vi-> sweepiv_test_2600.vi

  Possible reasons:

  VISA: (Hex 0x3FFF0005) the termination character was read.

  I disabled the stop character in him intialise Keithley 2600 vi, but the problem persists. The strange thing is that the code for the dredging of the V is exactly the same for I sweep (with obvious switches in the source and measurement).

  It seems that the levels of measurement/source are eventually go out of scope and causing the weatherstripping to end at the beginning. But even when I force ranges to a level that would deny such a problem, I always get the error intermittently.

  Any help would be greatly appreciated!

  You can change a property for the stop character node and allow stop character in port VISA.  It's under settings based on the Message.  However, I have not work with GPIB to know how he handles things rather than serial ports.  I don't have your Keithley VI to find out what's going on inside of them.

• VISA SERIES termination character producer consumer model

  Hello

  I'm developing a HMI to receive data from a sensor.
  Material sensor is built in my company and I have no flexibility with her. Only 2 RX & GND wires, no possibility of
  hardware handshake.

  The sensor send to an RS232 com port a string hex each 1 s, 10 s, 60 years or more and I can not know the frequency.
  So, I scan each data bytes to the serial port and serial port with VISA Read 20ms. At the end of the string hex sent by the sensor
  There is a stop character but I don't how to use it.

  I use the model producer/consumer do not lose any data.

  In fact, I read and concatain received data (with VISA READ) until I got the right number of bytes (because I know the size of)
  the sent hexastring is 495 bytes).
  But in the real work, I don't know the size of the data to be received by the sensor. (<500>

  So, I want to use the character of endpoint to stop the loop of producer that contain VISA READ.

  Should what special function or the property node I use to do this?

  I've attached a screenshot of JPEG of my code.

  PS: for the development of the VI, I simulate the sensor data with another PC that sent the hex string in loop
  with the stop character.

  Hello

  A method to read an unknown number of bytes: put just the bytes to the Port in the whole loop (not read). Place the output of bytes to the Port into a shift register and compare the latest iteration with the current. When the number stops change (current loop = last loop) then all bytes have arrived. Bail out of the loop so directly while reading VISA.

• Stop character does not Change

  Hello, I use vi to establish and send to a serial port. When I try and change the stop character on the front panel of 0xA (\n) to 0xD (\r) and try and scroll the vi that I find that the stop character constantly 0xA that is not what I want. What I am doing wrong.

• VISA READ stops the playback to the 'zero' - tank

  I read a message to binairy, from a RFID tag that looks like this:

  spell [01 09 0C 6th B9 53 0 to 00 00 00 00 8B]

  The bytes to Port-property shows me the full message (12 bytes) is present in the port.

  I do a Visa_read with the 12 bytes as input, playback always returns with 7 bytes read.

  If the Visa_read stops to ZERO characters...  In a subsequent read I take the other 5 bytes.

  Why the VISA_READ stops at zero?  (I use XON/XOFF and the stop character is defined as 15, not zero!)

  Check the code below

  Thanks for the help in advance!

  In fact, I bet she's reading the 0x0A and you put in place of the port with the following default properties:

  • The end of the reading mode = TermChar
  • Char end = 0x0A
  • Char term remove for readings = True

  If you check the cluster of error of the warning message will tell you that the tank of the term has been seen, there could be more data available...

  Enable the implementation of the port with a F wired to the character of the period.

  EDIT: Oh the jpg clearly shows that I was right make T a F

• How can I send a GET command (Group execute Trigger) with the "VISA write VI"?

  I have an old Type of Yokogawa (1981) 2553 (DC voltage current Standard) with a GPIB and an Agilent converter USB to GPIB interface. So I write my orders using the "VISA write VI. According to the manual, I send the GET command after the other commands. How can I do this?  I tried to use the GPIB VI, instead of VISAS, but I always got the error 7: "NOR-488: Interface GPIB not found '...

  You cannot use the low-level GPIB functions because you are an Agilent controller. The low-level functions are only for the OR.

  Visa application, use the trigger to make visa.

• Reading series: maybe stop character?

  Hi all

  I'm trying to use labview to plot the data I send from a pic microcontroller. I'm programming in c pic so I can quite easily format the output. More specifically, at this time I sent hexadecimal numbers in this format "xxxx" on the serial port. I used playback advanced series and writing vi sample, got rid of the portion of Scripture, added a hexadecimal string to convert to the number function and send the output to a graph. My problem is to get the numbers down. For example if I send the FFFF number sometimes he read _FFF sometimes it reads FFF_ F_FFF etc., when of course I want to tread FFFF. I don't know how to solve this problem. I spent a ton of time on this because sometimes it works perfectly if i ' ts frustrating because I can't figure out what to do.  I have the following settings

  2400 baud

  5 bytes read

  input buffer 5 bye (not really sure that it should be)

  no flow control

  endless, read about the stop character

  So I thought maybe I should add a termination character to my output, such as \n... but if I have it and labview to stop read the stop character as soon as he comes to \n it stops completely. I'm sorry if this post is not clear, please let me know if you need any information, I really had an incredible amount of time on it so that any help would be great

  
  

• Serial RS232 Communication VISA write does not

  I am trying to send a SPELL of 5003 01 command to my card that I am logged in via Rs232. This command should get my PCB to change play modes.

  I posted about this problem before thinking it was a problem with it not sent in HEXADECIMAL:

  http://forums.NI.com/T5/LabVIEW/RS232-serial-communications-visa-using-hex-values-seem-to-be/m-p/326...

  It wasn't the problem.

  I use the CTS line for flow control. I know that the CTS signal is reaching the computer of my PCB as I tested it and I know that the PCB can send data to the computer I get the answer correct 4 bytes in HEXADECIMAL when I use the reading visa to get my player to PCB data.

  I get a 1073807339 error when I try to write even when the read function is disabled.

  The only thing I can think is that LabView is not to recognize the signal CTS go down and, consequently, time-out.

  I use the good 9600 baud rate, 8 bits of data and no parity, 1 stop bit. I am using RTS/CTS flow control, but the RTS line is not connected. I don't think it should be a problem that RTS is used to indicate the Council when to send data to the PC to my knowledge and is not serious.

  FYI the written string section of the VI is unused. The string to write, that's where I'm seizes my "5003 01" command.

  Thank you

  Kyle

  I just thought of it. I had messed up the wiring of the PSTN line. She received the RTS line, I think. I thought I had it correct since the Tx line was correct. Thank you for your help on the problem of the HEXAGON.

• VISA Write / read error

  Hello

  From what I saw this was not posted before.

  It seems that the error of read/write VISA is quite common and after reading through a few posts and try as proposed solutions, I find that nothing works. I am trying to contact my motor controller. I have implemented the correct COM port and the interface parameters (such as baud rate, parity, etc.). In the terminal program, termites and the measurement and Automation Explorer I can access and send commands to the controller and it works (the read buffer returns an error but always returns the correct answer).

  The format of the command is EN1\r 1 where 1 is the header and address, EN1 allows the disc and \r is the carriage return. Send orders in this format works. BUT in the program I wrote that I get error infamous timeout as in the attached photo. I tried to remove playback VI but nothing works.

  Please any help would be appreciated.

  Kind regards

  Richard

  I'm quite sure your error (-1073807339, timeout) was published thousands of times before.  So if you haven't seen, you may not have tried.

  The constant string in your diagram, what is the display for this mode?  Is this normal mode or \codes?  A common error is to have it in the normal display and you send a backslash followed by an 'r', rather than send a carriage return character who presents himself as '\r' when the string constant is displayed using the backslash.

• Satellite M40X-184: problem with keyboard - only writes a character in 1 second

  Hello

  There is an interesting problem with my laptop, it cams with Xp Home edition with 1 partition, I used partition magic to create another and then format C:, after installation of XP Pro. Install drivers one by one, now when I try to write something in anywhere like msn, notepad or Word, she wrote just a character in 1 second;

  Like when I write "trial" he write in 5 seconds... Why what happened and above all how can I work this?

  Hello

  have you tried to uninstall the pilot how you installed? Maybe you should do this, I think it's probably just a software problem and no hardware failure.
  So you can also try to set the rate of your keyboard type in Control Panel-> keyboard control-> (delay repeat, repeat rate) and maybe it s just there a setting that needs to be corrected.

• TCP Read and Write at the same time

  Hello everyone,

  I have a question about parallelism in TCP connections.

  I know that it is possible to read and write on the same connection ID.

  So, if you ReadTCP and WriteTCP block each other, if you use the same TCP connection ID?

  Or to request more precise if I run two while loops, in parallel, with one end by calling WriteTCP and the other called ReadTCP.

  one of the delay of loops (or block) will be the other if both loops call their VI TCP at the same time right?

  The system is Windows 7 and Labview 2012.

  Kind regards

  Sebastian

  They are perfectly parallel.  Just write in one and read it from the other.  There is no conflict.

  See My TCP articles for more details.
