NOTICE
String manipulation when converting to STRING or WSTRING
When converting the type to STRING or WSTRING, the typed value is left-aligned as a string and truncated if it is too long. Therefore,
declare the return variable for the type conversion operators <>_TO_STRING and <>_TO_WSTRING long enough that the string has enough space without any manipulation.
The operands of type DATE, DATE_AND_TIME, TIME_OF_DAY, DT, or TOD, which are passed to an operator for a data and time conversion, are converted to
their constant syntax (literal syntax). The generated string contains the keyword
D#, DT# or TOD# and then the size with its data and time unit, as indicated in the IEC 61131-3 specification.
