UDINT_TO_STRING
Unsigned DOUBLE INTEGER into STRING
Generates a result string in right-aligned decimal representation, filled with leading spaces up to
the predefined maximum number of characters.
To add an enable input and enable output to the instruction, select [With EN/ENO] from the
"Instructions" pane (LD, FBD or IL editor). To reuse an instruction select "Recently used" from the
context menu or press <Ctrl>+<Shift>+<v> in the programming window.

Availability of UDINT_TO_STRING
 When using the data type STRING with small PLCs like FP-e or FP0,
make sure that the length of the result string is equal to or greater than
the length of the source string.

Example
In this example, the same POU header is used for all programming languages. For an example
using IL (instruction list), please refer to the online help.
POU header
All input and output variables used for programming this function have been declared in the POU
header.
The input variable input_value of the data type UDINT is intialized by the value 12345678. The
output variable result_string is of the data type STRING[11]. It can store a maximum of 11
characters. Instead of using the variable input_value, you can enter a constant directly at the
function’s input contact in the body.
