Hexadecimal string with UDP sending

Similar Questions

• Can I use a hexadecimal string with a case statement?

  Simple question:

  Can I enter a hexadecimal string to a case statement and have the case statement see it as hex?

  I understand that I could convert the hexadecimal string to a number and then enter the hexadecimal number to the case statement but I am curious to know if I could have the case see the string itself as hex without this added feature.

  Would be nice to not have to convert all my numbers throughout my code strings

  Thank you

  How long are the strings? Since you mention convert in numbers, they are probably short and all of same length.

  Are there different possible channels how?

  Case header includes \-codes in the case of a label deal selector As string, so that should be enough for your use. For example this code turns the LED (.. .so that a simple string of "\00\00" of wiring would not be!)

• Convert a single number to a hexadecimal string of 32-bit and exchange the high and low bytes

  I need to convert a number single precision floating decimal to hexadecimal format of 32 bits, share the high and low bytes and that convert a hexadecimal string.  I tried to use the 'Word of Swap' function but it seems to have no effect on the unique number.

  Then

  A single decimal number of entry: 100

  Convert 32 bit hexadecimal string with the low byte first: 0000 42 8

  Anyone have any ideas?

  Thank you

  Slightly lighter, try to cast U32 and exchange words. Same difference.

  (apparently, exchanging words is a NOOP for SGL, but still accepts SGL without constraint. Interesting...)

  

• create a hexadecimal string

  I want to send a hexadecimal string to a device.

  0000 0000 0006 0103 2 0001 07D

  If I send the string as written above, I get the expected response.

  2 07D is a register number and I would like the user to be able to choose the register. I created this code to see if I could insert the hex string required in the full string. (Note that string constants are in hexadecimal display)

  It works very well, producing the correct hexadecimal string, 0000 0000 0006 0103 2 0001 07D.  I send the string and the device reacts as expected.

  Since I want the user to be able to choose the registry I created a mechanism for it and replaced the constant substring (07D 2) with this code.

  (Note that the value entered in the D - Reg control no. 2003)

  Although the conversion of a hexadecimal string of product 07D I16 control 2, replace the hexagonal result string of the function subset string produces this, 0000 0000 0006 0103 3037 4432 0001.

  Can anyone offer advice or perhaps suggest another method?

  Thank you.

  First of all, when the formatting strings, you're better off the coast using the Vi of string marker rather than replace elements in a string. However, in this case your string format is retrungin you the representation of ASCII number and, therefore, you get an incorrect value in the output string. What you need to do is to replace the bytes of the string with the actual binary data, not the ASCII representation. One way to do this is to simply flatten the number to a string, then replace the bytes. You can also convert the number as well, and then replace the data. Here is an example.

  

• UDP send receive application

  I'm writing an application to send UDP packets. I had no problem with the send() call, but I would try to receive the message sent, perhaps on the same connection.  (I use another connection to receive in the same thread, but the result is the same).

• Hexadecimal string to HEXADECIMAL number

  Hello Experts,

  I just stuck in a simple problem. in fact I'm having an array of string HEX I want to convert it to HEX number format, I am looking for this conversion. It's that simple, but I can't do this job. Please see the image to join for more understanding.

  

  Soon harry and thnaks in advance

  Harry,

  You can do this (and many other conversions from string to a number) with analysis of the chain. %x indicates LabView input data are hexagonal. There are also a lot of string functions to a number (for example ' in hexadecimal string to the number") which could be faster if you do this 100 000 times in loop, but analysis chain will solve 99% of your problems.

• quick help hexadecimal string

  I know it must be very easy (or I guess, it should be), but here's my question:

  Side block diagram, how I translated the string so that it enters the right hex format, so when my rope is 0907 in hexadecimal, my light. Basically, I can't format the string to a 0907 of weird symbol that it is now. I know it has to do with the way in which the string is stored as a "normal string" vs "hexadecimal string", but could someone show me how to easily switch between the two on the side of block diagram? (on the VI side its as simple as right-clicking, but I was in trouble he is).

  Thank you - and have a nice weekend together.

  Your channel is actually two characters \09 tab and \07.

  Your structure case string should be "\09\07" will be converted to "\t\07".

• The hexadecimal string to decimal content content

  I write a code in LabVIEW to convert MBus data for some energy meters.

  Apparently the meter that I use sends the data as a string in hexadecimal format, however after correctly parking that string in hexadecimal format, the real value is the decimal number in this hexadecimal string without conversion.

  Example:

  -Response of the meter (String in hexadecimal display):

  68 37 37 68 08 07 72 89 12 13 67 A7 32 04 04 00 00 00 00 0C 06 09 58 02 00 0C 14 39 13 79 00 0B 2D 47 00 00 0 B 3 B A 30 32 00 5-0 HAS 81 03 0A 5TH 68 0 A 03 62 13 00 0F 21 04 00 00 20 86 16

  -After parking, I get 22 bytes to 25 (09 58 02 00) in the right order, i.e. 09 58 00 02 meaning 25 809 MWh.

  This means that I need to transfer sort the string in hexadecimal numbers to display a decimal format and divede by 1000 to get the correct value in MWh.

  I tried to use the Type Cast and Conversion of string without success. Can someone please help me find a solution?

  Best regards.

• Number of allocations of memory of hexadecimal string

  I am convert a string to a byte array and then converting this array of bytes into a hexadecimal table using the built-in primitive like this

  

  What is the best way for a performance? When I run the DETT I see multiple memory allocations. I think that one for each element of the array. I think it has to do with the point of constraint. Also, it happens only if I connect to the chain of the indicator. If I run this without the indicator chain I don't see not all memory allocations. (Perhaps LabVIEW do not know the code because I don't do anything with the result)

  I just got the DETT and I'm not very sure of how LabVIEW allocates memory. But I do a test by running this code

  

  I see not all memory allocations in the DETT as I do with the number of hexadecimal string.

  
  

• Converts a hexadecimal string to ASCII by VBAI

  Good day, experts, OR the

  I would like to ask for help on the stage of the VBAI calculator. Is there a way I could convert a hexadecimal string to ASCII character? For example 25 (Hex) to %(ASCII) or, if not in the calculator to other methods? I'll have to send data via TCP/IP later.

  Thank you very much
  Andrei K.

  Now I understand what you want. You can actually do from TCP step. First of all, you need get the length of the string in a digital as you did in step of the calculator, but then you can send this digital as a hexadecimal string of ascii to TCP step. To do this, have the length of the string as a numeric result in the return of calculator. In the TCP step, add a "Write" command and insert a result. Select the digital output of the step of the calculator and U8 of the data format. You can use the display/Hex Normal display to view the data that will be sent, and when displaying normal view, you can see that it is a '%' value when length is 37. See the attached screenshot to see how I did it.

  Hope this helps,

• hexadecimal string in hexagonal table

  Hello

  I have a hexadecimal string that contains the address then the word:

  8E39 0

  1 60E3

  1 B 2

  3 42

  4 100

  5 0

  I'm trying to create two tables, one with the address in two bytes and the other with the word of four bytes, so that I will eventually:

  8E39 00

  01-60E3

  001 B 02

  03-0042

  04 0100

  05 0000

  Any help will be greatly appreciated!

  Thank you

  hiNi.

  You can also directly use 'read the worksheet file' (but you will need to convert later to U16).

  You said you wanted two tables, must still be decided on two columns.

• Number in hexadecimal string conversion problem

  Hello

  for a serial communication, I need to send byte-code in an ascii hexadecimal string. When I use the constants and send them by VISA to the COM port it works fine, but if I use converters numbers it doesn't. Can someone show me what I'm doing wrong?

  Windows XP SP3, LV 8.5.1

  Since your string indicator is set to hexadecimal display, it seems you want to a hexadecimal string, a single byte/number.

  (You are currently using a hexadecimally format string, composed exclusively of ASCII of the 2 characters/byte "0.F" characters.) This is not what you want!).

  Here is another solution using type conversion:

  

• remove the two zeros of hexadecimal string

  I'm passing an ASCII string of bench to a VI I wrote and I start with "04" and my VI the ASCII get normal "04".  I then have to convert an ASCII string to a Hex string (using a solution of VI, which I found on the web) and instead, having it display Hex '04', it adds two zeros in the Hex display "0004".  I need to remove the two zeroes don't is just "04".  I don't know there is probably an obvious solution (I'm fairly new to LabVIEW).

  A statement of format for a cast of just wiring operation confuses the programmer. Don't, don't. The value is not important as the type. (.. .and if you want a string, you can't even wire type.) String is the default!)

  What is the representation of the blue zero constant wired scheme down to the left of "hexadecimal string to munber '? Make sure it's U8.

• I use different e-mail accounts: I send an email with the sender A (standard!), email is archived to the sender sent archive and the email is sent to the sender, B

  A really strange problem!

  I use different e-mail accounts. I send an email with a sender (defined as standard!), email is archived in archive A sent from the sender, the sender is wrote in the header of the email as the sender, but the email is sent with the sender B written as the sender in the email received.
