• How to convert the Ascii string containing hex to hex string info?

  Dear all,

  I am busy doing a control/reading program for pumps of ISCO.

  Right now I'm in trouble with to send orders for PUMPS in HEXADECIMAL. When I use a CONTROL to the STRING in HEX display, everything works fine (when I manually write down the command in the control of the chain).

  Exist it a couple of pieces order: string Destination, length, ordering, Checksum. I'm doing a sup - screw that automatically calculates the checksum (modulo 256) and adds it to the string. Everything is going well: first of all, I shared the ascii bytes command and I calculate the checksum and add as ASCII HEXADECIMAL value to the chain of command. Also a CR (= 0d) is added. Now the whole string must be converted to hex. The string contains the right nummers HEX, but they are in ASCII format. Here was I feel worth it, I don't know how to do it!

  So to summarize:

  I have an ascii string that contains the values HEX (for example 315230303652454D4F544531420D) and it must be converted to a HEX string (for instance 3152 3030 3652 454 4531 420 4F54) for the pump of the ISCO can understand the command.

• Related problem of Hex String

  Hello

  I would like to add 20hex string together & divide by 20, but somehow, I can't get the correct result.

  Attach with my vi here.

  Thank you and best regards,

  Simon

  Try the attached VI, I changed the lag that you used in the chain of research/split of 2 because you view the input as hex string, so when labview works on the rope he works on the ASCII representation of the string (which is a character), even if your display is in hexadecimal (two characters with an ascii character) so you only need to divide at an offset of 2 instead of 4. For example, direction = FFFF.

  Why don't post it your questions "convert x to y ' in one thread?

  

• Y at - it an easy way to change 323 (string) for "43 01" (hex string) or 3249 (string) to "0C B1" (hexadecimal string)?

  It depends on type of exactly what you want in the end.  Do you want a channel which shows the 4 characters who are the hexadecimal number for the number you enter.  Or do you want a channel which has only 2 (1 for each byte) characters, but the indicator is formatted to display those hexadecimal display?

• Concatenation of Hex and bites of ASCII to get a HEX string

  Hello

  I'm trying to concatenate a MODBUS Application Protocol header with a function code and data that I send over TCP/IP to a motor controller.  I am running problems when I try to read my code function and data length.  I use "string length" to read the order data that I am seized, that convert a hexadecimal number, and then that the concatenation with some strings constant hexadecimal display and my function code and data which is also in the hexadecimal display. When I concatenate the lines, the end message is incorrect because (I think) the length of string, I have read and converted to hex in ASCII text?

  Does this sound as if that was the problem, and if this is the case, can someone help me to fix? If this isn't the problem can someone help me understand what is?

  Thank you

  Ran,

  Converting to hex it will show as ascii, it is what it is, a human readable number represented in hexadecimal. What if all you want to do is add the gross value, then convert this to tank and add it. For example, if you have more bytes data then 16 then you will add two additional bytes to the end instead of one.

  

  What if all you try to do is add a vale bytes that represents the amount of data you send simply converted in a single tank and add, as shown above. Of course, this means that the length of string cannot be greater then 256.

  Even if you have less then 16 bytes of data to the hexadecimal value added at the end is only 1 tank so unless the receiver is supposed to read a hexadecimal value, it will be always wrong. For example, 1 in hexadecimal read like 49 gross.

  Hope this helps,

  RGS,

• A string that can be displayed as ASCII and hex in an indicator will allow not to store the data in a file in ASCII format

  You can see the data in an indicator very well, but when we try to write this string of hexadecimal data in a file, it will only save the data in ASCII format.

  This seems simple enough, as the indicator can be selected to display the data in different formats (VI > properties > appearance > display Style: Normal, backslash, hexadecimal).  However, I could not, for the moment save data in different formats.

  Altenbach says:

  ... or you can just read the string: text.text property to get everything that is actually displayed.

• Concatenate the hex strings

  In the attached example, VI is there a way to have the 1 b be represented as Hex instead of ASCii after the output string concatenation? Why function concatenate strings automatically converts the 1B in ASCII?

  Rather than convert the number to a string of ASCII characters, you should change the representation of the byte in a string. If you always want only a single byte, use the U8 instead of I32 data type. Convert an array of U8. Convert to string. Concatenate. Lynn

• integer to hex string

  Hello gentlemen,

  I'm having this problem try to send a 18 bytes in HEXADECIMAL string according to my device using the TCP Write.vi request schema

  As you can see in the attachments, if I use the string concatenation function and hardcode the 18 bytes as constant as HEX display, the message is valid and the device responds correctly.

  The next step is to have F and 11 as user input bytes, so I replaced the two constants '14' and '15' with two digital inputs and using the hexadecimal string number I hooked up the output of the function F of Byte and byte 11.

  The output of the number of hexadecimal string is correct as I enter the value 20 and function converts to 14 (hex) if I have an indicator of the value to the normal display.

  If I change the indicator to display Hex then I get the ASCII representation of the value 20.

  The problem is that if I connect the output of the number of hexadecimal string to the string to concatenate instead of the constant value 20 is represented as "3134" as ASCII.

  How can I convert a value of 20, which is a hexagonal I32 14?

  I've attached a few screenshots of the code working with constants and does not not with I32 conversation Hex.

  As your values may go in a single byte, change your your two entries U8 or I8 data type.  After that, just use Type Cast to change these bytes to a string.

• Hexadecimal number to hex string

  Dear moderators of Labview and experts.

  I'm looking for a simple tool, but could not know.

  Could you help me?

  I want to convert a hexadecimal string, Hex number unchanged.

  I mean digital Hex display shows E8 and I convert it to a string and I have Open indicator string Hex window and get the same answer E8.

  Someone knows how to do?

  I thank very you much in advance!

  cast will do what you want.

  

  (Make sure that digital is U8 and the string is defined to display hex.)

• String ASCII to decimal string and its sum

  Hi all

  I am a beginner in Labview and this is my first post on the forum.

  I get a package series "1200F" on a MCU COM port. These are all ASCII characters.

  I want to convert all of these ASCII characters into decimal numbers and add their decimal values to get the sum. So I took the ASCII string in a table using "Array of strings of bytes" and then typecast this constant using type U8. I put this in a loop and collects the decimal value using the Array function build. So I "Add elements of an array" function to add these decimal values to get the sum.

  The problem is that for the input string, I am able to get the sum of "1200" only. At the time wherever I type the last character ASCII F, the sum does not. I see that when the sum exceeds 255 it resets again from 0. I have attached the VI for reference.

  Any help would be appreciated.

  

  Convert 32 to avoid the limitation 255 of U8.

• normal string to hex string

  Hi all

  This question has probably been asked before, but I can't seem to find a situation that quite matches the issue I am experiencing. I have a table that I flattened as a string of data, reverse order, take the first two elements, reverse the new order and feed the characters in a loop for. I want the string to hexadecimal, thus having FE0C (in hexadecimal) through the loop for, but when I select the execution I see that normal display characters cross instead. When I view my channel, I already have a right-click to display the hex that is correct. How to convert the normal string to a hexadecimal string?

  Thank you

  J

  You can use Type Cast to change into a U16 (since it is supposed to be 2 bytes) or the Unflatten of the chain.

• Conversion number to a hex string

  Hello

  I want to send a command string hex to a device via the serial port. The chain includes a fixed part (address, function, register) and editable part (setpoint). The fixed part is a string constant hexa (0106 0022) the editable part is a number (1000) converted to string hex (03E8). Finally, the two are coding pour get the final string. The problem is that instead get: 0106 0022 03E8, I get: 0106 0022 3033 4538.

  After concatenates two strings, it seems that the second part is turned into ASCI.

  I can't find the solution!

  Thanks for your help.

  Sorry, I saved the vi in a different version.

• Conversion to Hex string to a hexadecimal string that can be converted into a floating number with comma

  Hi, could someone help me please. I've been racking my brains out for almost three hours trying to solve this problem by trying different things.

  I have a code that retrieves a string of a robot control. The string is in hexadecimal and represents the number 1.234567. The string itself is 3FF3C0C9539B8887

  If I make a cast on the channel that I have, it simply returns the value zero.

  If I delete the control string, change it to hex and manually type in 3FF3C0C9539B8887 (so Labview auto updates 3FF3 539B 8887 C0C9) I get the result I need.

  However I can't find a way to do this. My apologies, someone out there is probably shaking he leads to something that is relatively simple, but I'm kinda new to deal with hex.

  Code is attached below in LV8 (although I'm under LV2012)

  Thank you

  The for loop is not necessary if you limit to 64-bit.

• Ascii to binary string string conversion

  Hello

  I am fairly new to LABVIEW but now I connect to a device using a serial RS232 cable.  In any case I use VISA read to get the output of the unit, and I wanted the device to return the output to ASCII format.  He is able to do, but now I'm stuck.  Now, I'm trying to convert this string of ASCII characters to a binary string.  In other words, if my release was a "Medley" of VISA Read, I have to be able to get a string that was '0111000101101110 '.  Any help is appreciated.  Thank you.

  This does not make much sense, because "0111000101101110" would be "SB" and not "QN". You want to throw a conversion 'lowercase' too?

  In any case, here's a solution that works with any length of string.

  

  This seems quite complicated. In general, it is easier to work directly in binary strings rather than binary to ASCII format.
