convert hex string to number

[mned]

Good Afternoon;

I am trying to do the same thing.  I am reading 8 bytes of data from a modbus gateway.

I grab the substring that I am interested in....if I set the display to normal the reading is non printable.....set to hex display the reading is 3098 should be decimal 12440 I believe?

This feels like I am close but not quite.............

If you have the section of the string that is your data, use Unflatten From String to convert to your number (either I16 or U16).  I say to use the Unflatten instead of the Type Cast since you can specify Big Endian or LIttle Endian.

You do have it.

Decimal 12440, whether it is U16 or I 16, will directly typecast to hex 3098.

If you don't think you have it, then post a VI that shows the data you have saved as default in a control and the way you are trying to manipulate. it.

Here it is, String2 and substring are set to hex display.

String2 is read directly from a device.

The payload of the string is 08B6.

I need to convert this to decimal......should be 2230.

the 2230 / 100 = the position that I sent the actuator to.......22.3mm.

I can not get the conversion......

I know my last post was with a different value than the first.....I have 2 different axis

Did you even try our suggestions (Type Cast or Unflatten From String)?
