When I concatenate hex values in 2 different ways a get different results

[Threads]

When I concatenate 2 strings in "hex Display" the result is what I want.  When concatenate a [decimal number converted to a Hex] with [a string in "Hex display"] the results is very different.  Attached code shows the 2 cases.  In my code, why is "LDD_Command 2" different than "LDD_Command"?  Thanks.

Because in one case you are converting a number to a hex string, then displaying that as the hex values that make up the ASCII characters.

0000 hex is 0000 hex.   0000 as a string is 3030 3030 hex because is zero is the hex value 30 in the ascii table.

When you convert numeric to Hex string, it gives string in normal representation (LDD_input indicator). You display it in the string with Hex representation (second part of LDD command 2), they are not equal.

If I got you right, you need to display data (0CCD is hex for 3277=u16(1/20*65535). So you need to have data with string representation - data should not change, only the way you display them should. This is done with the type cast.
