This is a 64 bit number, how do you want to convert it: to a byte array, as a single i64 or u64 integer, another way?

Hello developer,

you also have to define what a "binary" is! Do you want to have a boolean array or a string containing "0" and "1"?
Converting to a different string is easy: Use "Scan from string" to convert your hex string to a number and "Format into string" to get a boolean string. The format codes are "%x" and  "%b", respectively. You can also use the intermediate number to convert to a boolean array.

First point to note - as already mentioned, the hex number equates to a 64 bit binary number, and it's only since LabVIEW version 8.0 that 64 bit integers are handled.

Presuming you have LV 8 then see the attached VI...

Important: You must wire a 64-bit integer to the "default" input of the "Hex to Number" function, if you want the function to return a 64-bit integer output, because otherwise it will return a 32 bit number by default (legacy from before LV handled 64 bit integers) 

Mark.

P.S. If you don't have LV 8 then there would have to be more code involved to split the hex string into two parts, then convert the two parts before recombining into a 64 bit string..

Try this vi. Note that we need to split the hex string in two parts each 32 bits long.
