How to send HEX data by LabView TCP Socket

[huaew]

using LabView2015, string data can be sent by TCP/Socket, How to send HEX data ? 

[crossrulz]

There is typically some kind of message protocol you have to follow to talk to your device.  Please share that protocol so we know exactly it is you need.  I have seen too many versions of "Hex" data to feel comfortable giving an answer with that exact protocol.

Right click on the "data in" constant or control wired to the TCP Write function and select Visible Items -> Display Style and then select Hex Display. You can also wire an array of bytes to the data in input.

Thanks.

but I can't find the way to use in LabView2015.

do you have such a vi file ? would u like to attach a copy.

You were given steps to produce the code.  Did you try it?

A string can contain all types of numbers, even hexdecimal numbers. 
Example:

Do you need help for how to format a integer to a hexadecimal string or do you need to send a byte or byte array.
Since a byte just contain a value between 0 and 255 (decimal) your question is a little misleading if you ask for how to send hexadecimal data.

I would like to ask the same question as crossrulz, could you share information about your  message protocol.

I want to send byte array. such as send 0x08 0xa0 0xe0.

Hi huaew,

you still don't attach your VI…

1. Then you need to create an array constant.
2. Place a "byte" (aka U8 integer) constant in the array constant.
3. Change the display style of that U8 constant to show hex formatted values and show the display style indication…

This is pretty basic LabVIEW knowledge: did you take note of those "Training resources" offered here?

Excuse me if I am opening an old forum, I need to send the frame string "Trama_Elip.T_Definitiva_ELIP" in hexadecimal format (I am attaching an example of the frame:

4C410000203030303229317CAA05A09900000000000000000000000000000000000000000000000 000000000000000000000000000000000000000000000000000000000000000030000000000000 ).

I tried this way "Right click on the "data in" constant or control wired to the TCP Write function and select Visible Items -> Display Style and then select Hex Display.", but this only works when applied to a constant, in indicators it does not give me the Hex Display option, please help me by explaining how I can send that frame in hexadecimal.

I've attached some images so you can see the code.

The pictures don't show an indicator, they show an unbundle by name node.

An indicator looks like this on the block diagram:

And would look like this on the front panel:

On the front panel, you can set "Display style":

I suspect what you really need to do is to convert ASCII text currently showing hexadecimal bytes into a byte array.  Can you confirm?
