I was trying to use some of the conversion function blocks in my application and little bit confused to understand the implementation of function block STRING_TO_BYTE or any other datatype format from STRING/WSTRING.

My ideal understanding is that string/wstring which is a collection of characters when converted into a byte datatype it should represent each character in the string/wstring as byte(AscII) .
like for example "ABCD" should have four bytes [65,66,67,68].

or is this used mainly like atoi?

Hi,

thes functions are mainly used similar to atoi. the problem with your expectation is that then the output of the functions would need to be an array. Even worse the size of array is determined by the size of the string.
